The simple test of HP Mini 2133 battery

Let us take a look at this HP Mini 2133 battery life. From our point of view before the media coverage of such Internet features of this product is any time a free tour of the Internet. This function perfectly or not, is bound to need strong support of the power system. To this end, the HP Mini 2133 is equipped with a three-core 10.8V 28Wh lithium ion battery, the life test results are as follows:

The final results, in the full-torn BatteryMark 4.0.1, the piece of the battery capacity of adhering to a moderate 73 minutes (in this test phase HP Mini 2133 to 70% of the screen from top to bottom, and power management in XP system on the all power-saving features of the option off). If the day-to-day use, can reduce the screen brightness, and then associated with energy-saving function of the operating system, I believe that this battery may last 100 minutes usage time, the same time the satellite A300 battery can work 250 minutes.

Evaluation of a line of the products are excellent, I believe that their long working hours under the state of the performance of body temperature can also be regarded as one of important criteria. After all, no one is willing to use a long period of time may be the Internet version, the body temperature to achieve the degree of fried eggs. To this end, the author carried out in the HP Mini 2133 battery life test, the use of the testo 825-T2 Infrared Thermometer their body temperature was tested (the testing process in the basic maintenance of the indoor temperature around 25 degrees Celsius ).

To the final testing results, HP Mini 2133 battery in the performance of body temperature can be used in this part of "disorder" to make an assessment. The main heat source is basically in the left side of the keyboard and the left side of the fuselage cooling air vents, under the late拆机inspection, the region where is the processor. VIA C7M processor so "hot" performance really let my accident. In addition, the HP Mini 2133 notebook cooling Apple Design and passive fanless cooling body has some similar, are relying on the most metal body heat away. Therefore, HP Mini 2133 in the use of process engineering plastic materials than other Internet users this will bring the feeling of heat.

Might see here, there will be readers to PC Mark05, 3D Mark06 Although the classic, but I do not know this will be the actual performance of the notebook is. You can not come to the actual point? OK, of course, no problem! The needs of readers, that is our goal. Next, I look for you to display the HP Mini 2133 HD video decoding ability.

Proficiency test in high-definition decoding of H.264 I selected encoding format, video resolution of 1280 × 720 specifications "Teenage Mutant Ninja Turtles" to carry out the tests. As shown in the following screenshot, HP Mini 2133 in the performance tests can be described as barely passing. But its good sound, images can be synchronized, the screen is still a natural transition. During playback, HP Mini 2133 occupancy rate of the basic processors in about 90% of the entire process. Used as a VIA S3G UniChrome Pro II integrated GPU, system bus frequency is only 400MHz notebook, this performance is still talking about the past. HP Mini 2133 is HP addtion in netbook to support HP Pavilion DV1000,Pavilion DV3000, DV4000, DV4, DV5, DV7.

As shown in game screenshot, HP Mini 2133 in the performance of the game is also still far from satisfactory. More than two games in high definition is not set up the premise, can smooth out the feeling. Perhaps this author is really some redundant tests, select Netbook "Internet of the" consumer products more convenient for a working or living conditions, most of them has been interested in the age of the game. However, I would like to express here is that, HP Mini 2133 in your spare time can also become a tool for your entertainment pleasure. Perhaps it is not strong enough performance, but occasionally or inadequate.

As HP's first ultra-portable mobile notebook, HP Mini 2133 HP carried on "with the most user needs for a wide range of mobile solutions," the commitment to "full-function ultra-portable + + the best experience" to meet the unique advantage of increasingly strong The ultra-portable mobile needs. Its elegant exterior design, whole weight of only 1.19Kg, measuring only 27mm (positive) × 255mm × 165mm, its concise and well anodic alumina shell design, while ensuring at the same time compact and durable machine can reduce the weight of ; in the main configuration, equipped with 1GB or 2GB of memory (only has one memory slot settings), Genuine Windows Vista Home operating system, as well as standard disk drives, can provide fairly good experience.

HP Mini 2133 Review of the advantages and disadvantages:

Advantages : 1, many of the products in the Internet the only model of a metal material, and excellent mold design
2, speaker sound quality on both sides of the screen, in many of the Internet's most successful products
3, such as 3D DriveGuard with hardware and software protection system hard drive, hard drive data more secure
4, key-bit layout is unreasonable, moderate-size keyboard, excellent use of hand
5, to break the trade restrictions, the provision of 2GB memory as XPS M1530 XPS M1730 PC, 160GB hard drive configuration

1, the normal body process of high temperature than those for similar models, the use of higher ambient temperature
2, pre-installed Vista system, the current allocation of the burden too heavy
3, six-core version does not provide battery life is too short

It to a lot of people compare Apple Macbook Air Apple Macbook Air as "the ultimate thin and light" and the ThinkPad X300 is a "no compromise light" here refers to the uncompromising performance, the existence of Apple Macbook Air interface less than , non-standard optical disk drive, memory card there, and many other battery change not regret, and the ThinkPad X300 is more comprehensive.

Light, is the beginning of thin ThinkPad X300 notebook to get the first impression, as is currently the lightest full-featured notebook 13 inches, really deserves. Whole transmission is still the appearance of the "black" appearance of the classic, although the machine has been monotonous black as main color, but it gives the feeling of losing fashion. Its powerful battery is litium battery as VGP-BPS8 VGP-BPS9 VGP-BPS11 VGP-BPS13. The reason why such a thin and light ThinkPad X300 with its use of the material body has a great relationship, X300 using CFRP carbon fiber and glass fiber GFRP as top and bottom of the body material, to ensure a solid body of good control at the same time weight machine.

Thinkpad X300 battery using locking design, unlock the front left is located in the fuselage, one-handed opening and closing of the notebook some difficulties, but the benefits of this design is the security of the notebook have a good guarantee. Of course, there are less than each notebook, I use the X300 for some time, found that the shaft resistance of a small notebook, so I do not know the design of the notebook, or more than the number of opening and closing of cause; In addition, the skin texture of the matte notebook region, if the user the situation in this touching and humid, it is easy to leave a mark, but it is very difficult to remove.

Thinkpad X300 interior design, in the whole extension of the ThinkPad is still the IBM traditional style, in the middle of the screen set up above the 1.3 million-pixel camera, the camera lights next to the keyboard, user-friendly to use in the dark. In the look down in the notebook inside of the two axes are the logo and the Lenovo logo X300.

Relatively rich interface X300 is a big selling point, many people give up Apple Macbook Air and X300 choose one of the major reasons is because this point. Although the X300 compared to the ordinary 13-inch notebook interface or worse, but has been used to meet the day-to-day. The following is a notebook specific distribution of the interface.

In fact, the whole performance of X300 can only say that it is ordinary, Core 2 Duo L7100 processor frequency of only 1.2GHz as thinkpad X200 battery, but the application of the ordinary day-to-day, or enough. In fact, the hardware configuration of the X300's biggest bright spot is the hard drive is equipped with, X300 uses SSD solid state hard drive, SSD solid state drive uses NAND flash memory, hard drive not have to worry about the collision of data loss, which greatly raised the hard disk data security.

Overall, this notebook is remarkable, 13-inch thin frame, 1.33 kilograms of whole weight, the excellent performance of the hard drive, LED screen, said to be worthy of the ThinkPad family of a milestone for inspiron 6000. But there are also many places with some regret that the general processor performance, interface, or a little weak, especially the price of the current wetlands, or some to be prohibitive. The X300 is currently priced at 24,999 yuan, more suitable for high-end business users, especially for a portable notebook and endurance than the value of this part of users.

Customers Rating :

Doesn't hold much charge, maybe an hour (when it was NEW). Now that it is a year old, it holds ZERO charge. If I unplug my computer, the battery holds no charge and the computer crashes immediately. Poor quality, poor value.

The battery that came with my M1730 is so weak my computer shuts down 10 sec after I unplug it. I did not use the battery much - always plugged in. The price is absolutely ridiculous for something that only lasts a year and provides 1 hour of power.

In the end the xps m1730 battery is a new battery as sony VGP-BPS8 VGP-BPS9 VGP-BPS13.There maybe some replacement in the market, you can select a cheap replacement for your OEM battery when you long working with battery. As the frequent "long time discharging" can damage your OEM battery.

Dell XPS M1530 battery customer ratings

Owerhouse of a battery. Charge lasted far longer than the 6 Cell I had prior. I still liked the look of my computer even though this battery was bigger (More bigger than inspiron 1520 1720 9cells battery). The extra weight was not a problem (I am female and not very big.)

It Made my computer (XPS M1530 Laptop) so hot I had to return it and buy the 6 Cell. I could feel the heat off the touch pad and where I place my left hand when typing (where the hard drive is located.)

ConsThis battery is nothing special. Yes it is 9 cells but the poor quality of the battery counteracts the fact that it has 2 extra cells as 9cells latitude D620 battery and latitude D820.

I called tech help who did verify that the battery has more "mass" therefore would be hotter. I was surprised by this because what I had read here had me thinking it would be cooler than the 6 cell. It wasn't. Too bad it was neat.

In all , this 9 Cells XPS M1530 battery is more powerful than 6 Cells XPS M1530 battery, also it become more hotter than 6 cells..

The basic structure of electric cars

The composition of electric vehicles, including electric drives and control systems, power transmission and other mechanical drive system, complete installation tasks. Power driver and control system is the core of electric vehicles as well as internal combustion engines of motor vehicles from the largest difference. Power driver and control system by the drive motor, power supply and motor speed control device and so on. Electric vehicles equipped with the basic and the other the same internal combustion engine vehicle.

2.1. Of electric vehicles, electric power cars

Power for electric vehicles, electric cars provided by the drive motor power, motor power of the mechanical energy into electrical energy through the direct drive gear or wheel and the work device. At present, electric vehicles on the most widely used lead-acid laptop battery power source is, but with the development of electric vehicle technology, and many are developing new type of battery. These power supply (batteries) are mainly sodium sulfur batteries, nickel-chromium batteries, lithium batteries, fuel cells, flywheel batteries, etc. Application of the new power supply for the development of electric vehicles has opened up broad prospects.

2.2. Of electric vehicles, electric cars drive motor

The role of motor-driven power supply is the mechanical energy into electrical energy through the direct drive gear or wheel and the work device. At present, electric vehicles, electric cars on the widely used series-excited DC motor, this motor has a "soft" mechanical properties, and the car is very consistent with the traffic characteristics. However, due to the existence of DC motor commutation spark power than smaller, less efficient, maintenance workload, with the electric motor control technology and technological development, it is bound to gradually brushless DC motor (BCDM) (Latitude D620 battery), Switched Reluctance Motor (SRM) and replaced by the exchange of asynchronous motor.

2.3. Of electric vehicles, electric car motor speed control device

Motor speed control device for electric vehicles, such as variable speed and direction of change set, its role is to control the motor voltage or current, the completion of the drive motor torque and the control of rotation direction.

Early electric cars, electric cars, electric cars, electric cars using DC motor speed control or change the electrical series resistance of the magnetic field coil turns to achieve. Because there is a level of speed and will produce additional electrical energy consumption or use of the structure of the complex, it is now seldom used. At present, the application of electric vehicles is a wider range of speed control thyristor chopper through the uniform change of the terminal voltage motor control motor current, to realize stepless speed regulation motor. In the electronic power of the continuous development of technology, it also gradually by other power transistor (into the GTO, MOSFET, BTR and IGBT, inspiron e1505 battery etc.) to replace the chopper speed control devices. From technology development, along with the application of the new drive motor, electric vehicles into the speed control of DC Inverter technology, will become the inevitable trend.

Electric vehicles, electric cars in the drive to transform rotary motor control, DC motor armature to rely on contacts or change the current direction of the magnetic field, the spin motor to achieve the transformation, which makes circuit complexity, reliability, lower. When the exchange of asynchronous motor drive, the motor can turn to transform the magnetic field changes the phase sequence of three-phase current to enable simplified control circuitry. In addition, the use of AC motor and VVVF control technology, electric vehicles, electric cars the braking energy recovery control more convenient and more simple control circuit.

2.4. Of electric vehicles, electric cars gear

Electric vehicles, electric cars is the role of transmission of drive torque to the motor vehicle to the driveshaft, when the use of electric-wheel-drive, the transmission components are often the most can be ignored. Because the motor can be activated with the load, so no need for electric vehicles on the clutch of traditional internal combustion engine vehicle. Because of the rotary drive motor circuit can be controlled to achieve the transformation, so no internal combustion engine for electric vehicles in the auto reverse transmission. When motor stepless speed control, electric vehicles can be ignored traditional transmission vehicles. In the use of electric-wheel-drive, the electric vehicles can also be omitted from the traditional internal combustion engine vehicle of the differential transmission system. I also charge my inspiron 1520 battery in my electric vehicle.

2.5. Of electric vehicles, electric car driving device

Electric vehicles, electric car driving device which is driven by the motor torque through the wheels into force on the ground, the drive wheels running. It with other vehicle components are the same, by the wheels, tires and suspension components Pavilion DV4 Pavilion DV5 Pavilion DV7, Pavilion DV3000 and so on.

2.6. Of electric vehicles, electric car steering

Electric vehicles, electric cars for the realization of a special device is a vehicle set up by the turn by turn to drive, steering wheel, steering wheel and steering components, etc.. The role of control in the steering wheel through the steering and steering tilt steering wheel so that a certain point of view, towards the achievement of motor vehicles. Most electric vehicles for the front wheel steering, electric industrial forklift with rear-wheel steering is often used. Electric vehicles are equipped with a mechanical steering steering, hydraulic steering and hydraulic power steering VGP-BPS8 VGP-BPS9 VGP-BPS13 and so on.

2.7. Of electric vehicles, electric cars brake

The braking device for electric vehicles and other motor vehicles, is to slow down or stop and the car set up, usually by the brake control device and its components. In electric vehicles, the general also electromagnetic brake, which can be used to control motor-driven electrical power generation circuit to run, so that when the braking deceleration of energy conversion into the current battery, which has been recycled.

2.8. Electric Vehicle electric cars work device

Electric vehicles, electric cars is the work of installation of industrial electric vehicles operating requirements for the completion of specialized settings, such as electric forklift lifting devices, door frames, forks and so on. Fork lifting and tilting the door frame is usually motor-driven hydraulic systems.

The HP notebook Problems in 2009

Problems with faulty Nvidia graphics chips that caused large numbers of notebook computers to fail last year may not be over yet -- at least for some.

Some HP users are complaining that their laptops, which were not included in the company's official list of affected machines, are facing problems similar to what other users experienced last year.

"When I boot up my laptop, it says there's no driver and I can't install one. That means my machine locks up and shuts down," says Dana Hight, a HP notebook user who runs a web development company. "It is clearly related to what happened with Nvidia chips last year." Hight has bought his laptop about a year and half ago.

But he, along with other users in one of HP's online support forums, say the company won't recognize his laptop model as one of the versions affected by the faulty Nvidia chips. Hight has the DV9549US model. HP did not respond to a request for comment about the complaints. Now Lenovo update its ThinkPad X200 to solve this probelm.

Last year many consumers saw notebooks and desktops PCs that refused to boot up, did not detect wireless networks or offer any video on the monitor. HP acknowledged problems with about 38 desktops and 14 notebook models, Pavilion DV5 battery. In October, 2008, HP issued BIOS fixes and a limited extended warranty for these machines. Nvidia has said a problem with the packaging material for some of its chipsets led to the high failure rates. Dell and Apple also reported problems with Nvidia chips in 2008.

But Hight and other users in HP's forums complain that their notebook models from the dv95xx series are facing similar issues.

"About two months ago I started noticing flickering and the system locking up, shutting down and rebooting," says Hight. "It started getting worse but HP told me their technicians are not aware of anything with my chipset for HP newest notebook Pavilion DV7.

Hight, who had bought extended warranty with the now bankrupt Circuit City says he has two options: to pay up to $400 to get a new motherboard, but with the same chipset from Nvidia; or buy a new machine that will cost hundreds of dollars.

A quick look through a thread on one of HP's online support forums reveals similar complaints. HP technicians, say the users online, will not acknowledge their problems as being related to the bad Nvidia chips.

HP has not responded to Wired.com's request for comment. Pavilion DV4 battery

Hight says HP should step up and replace the faulty laptops instead of offering piecemeal fixes. "I would expect HP to give us a solution," says Hight. "Why should users who paid $800 to get a HP laptop have to pay now because they got a bad machine?"

In the last article we learn how to calibrate the battery cell. Now let me introduce how to repair the shell.

Points and then encountered trouble: it was soon filling power (twice as fast than normal), in the course of discharge to 70% of the time will suddenly prompt "The battery is dead, please insert the AC power supply" warning capacity to show an immediate 5%. The beginning of a long time thought it was not using the battery leads to memory effect, we should do like a few of the deep cycle. But after several full charge, after release and found that the improvement is very small, only about 45 percent take power, with half an hour, we still have the problem. The largest may be the Inspiron 1520 battery pack in more than one section or "black sheep" in trouble, have to pull it out!

Red several times in the subsequent discharge cycle every place is full of electricity and have finished after the battery power to open, measuring the voltage of each battery pack to find a group of "different": the per-charge when it voltage to reach 4.2V or even more than the first, leading to cessation of the entire VGP-BPS2 battery charge, and discharge when it was first to reach 3.6V or even less, is a typical decline in capacity. And the largest of which may still be a battery problem. This group of cells separated from the measurement of voltage, respectively, found that a battery voltage is low, only about 3.2V, a separate charge of their voltage quickly reach 4.2V, less than a minute of time, The A1185 battery basically has no capacity to speak with a light bulb when the discharge was found, it has the fundamental output current that can not provide even less than 1mA, measuring its resistance, has reached more than 2K seems to have been scrapped.
As a result of a "shock therapy" after the restoration of the normal cells, but not charging voltage reached 4.0V, it seems that it is "the pot boiled dumplings - do not put out an electric" soldering it back a battery discharge followed by the use of time of up to 90 minutes, has been near normal level of the battery.

However, when the charge is quickly filled, and disturbed mind up soon. Was a discharge, it is less than half an hour, open a test, just fix the bad and the battery.

Not always have to use a "heart to recover," ah, so the value on the lost.

This section of the final decision to do a battery operation, and then they can not, then replaced the batteries. Peeling of the batteries, removed the insulation near the cathode cap and found a slight corrosion around, but I do not like battery leakage and traces, as well as save. With halogen lamp from the battery positive and negative, there is no response Taking into account the previous "Anatomy" the same symptoms when the batteries are inside the battery with the battery cathode output between cathode cap (the pressure on, not welded) oxide occurred, resulting in increased resistance and end-of-life battery , and the internal battery is still good. Oxide layer in the case is not serious as long as the battery cap to strengthen the internal contacts and battery resulting in the battery does not leak if damaged can be restored. The simplest way is to step up the battery forceps are negative (one pad insulation film), while measuring the inspiron E155 battery output voltage (or current), while vertical extrusion batteries, once the battery output voltage is increased, the current increase (the change is often the jumping in nature, relatively large changes) to stop immediately, the battery will be able to repair.
The top edge of the battery cathode cap next to the mouth ventilation valve with cutting pliers, then immediately measured and found that the battery has been restored, the output current increases immediately. In order to insurance purposes, the battery cap in the week between the edge of the chisel a few more in order to increase the contact area to ensure that the use of effects.

The battery to re-wrap, solder back to the XPS M1210 battery pack, charge, discharge. The use of time to reach more than 90 minutes.

Again measured with test software and found that the current capacity of smaller 38.88Wh from the original into a 32.07Wh, a decrease of nearly 20 percent, but this is the real discharge process, there is no jump of dropped. After several red discharge cycle, the capacity has increased by some. Use has been made to the current two months, everything will be all right.

Repair battery 1: calibrate cell

First of all, the test voltage to zero, the machine can not start naturally, can not use power when charging (the battery light does not shine).

Disassemble the battery, more or less talk about the situation inside the battery.

Battery in a total of 9 can be placed 18 millimeters in diameter, length 65 mm core CGH18650 models the location of lithium batteries, Panasonic's 22 batteries in parallel, three groups of series (OK, then my new Latitude D620 battery, the same, it appears that is 6), there is a very fine control with a single chip - the protection of the circuit, the circuit to the computer a total of five output contacts, respectively, are negative, the clock and data.

First of all, check the sticky in the battery temperature detection probe (temperature resistance), and temperature protection insurance, are also normal. Test-retest the battery voltage of each group, in which two sets of battery voltage of 3.8V, normal; a battery voltage of 0V, appear to have lapsed. The total battery voltage of 7.6V, then the failure of the battery pack has not yet open, then measuring the internal resistance was very small, almost in a state short-circuit.

First of all, failure to deal with Thinkpad T60 batteries, battery repair based on previous experience, the failure of the battery may not be completely damaged, can be activated through a number of methods, in particular the performance of state for the short-circuit the battery. The voltage of the battery to 0 with one end connected to the circuit board off line to avoid damage to circuit boards in operation. Open-circuit battery voltage after the re-survey, is still 0V, ruled out the possibility of short-circuit boards.

For short-circuit the battery failure, the method is more effective high-voltage electric current moment method, using the old IBM power supply (my back-up power), 16V maximum 3A output string on the multimeter (a tributary of the current file 20A), first negative power supply Even with the battery anode, and cathode power multimeter then red table pen, table pen with black multimeter battery cathode touch, speed, faster as far as possible, the former two degrees to see the multimeter has reached close to the 2A (moment) and the third on only 0.4 A about an immediate stop, measure the battery voltage has been restored to about 3V, the internal battery short-circuit that point has been an instant high-current boil (If you do not damage the battery to stop immediately, even if so, battery life and capacity have been the impact, if conditional, or recommend replacement, but if the replacement, then try to replace the entire battery pack are). However, the batteries need to be a separate charge (if the battery charge of the whole group, this will result in the other two groups had mesenchymal cells), plug in the charger to start charging ammeter to monitor during the charge current to 500mA or so, current for the 3.6AH battery pack is small, but the charger is the charge current is limited and a small current to the xps m1330 battery charge is good for the resumption. After about six hours, the charger showed the battery is already full, continue to re-charge for about two hours, remove the battery, measure voltage has reached 4.2V, with bright halogen bulb in the flashlight (3V, 500mA) to discharge its , bulb sharp discharge current of 700mA, the battery pack that has been basically restored, continue to discharge until the battery voltage down to 3.8V, the purpose of the two groups with the same battery voltage, charging time together so as not to overcharge the Back to the whole battery pack battery circuit welding.

Since the inspiron 6400 battery voltage while the circuit board there is no output, then, surely have damaged circuit boards, after observation, negative input circuit board (take battery) output (then output contact) is directly connected, and the positive input and output of by a high-power thyristor control, the thyristor remains cut-off state, that is, the control circuit has not been output control signals to the SCR control terminal, or simply the SCR has been destroyed. (Measured after the control signals that I did not) because I do not have the ability to repair single-chip microcomputer. IBM to take into account the protection of the BB more perfect, is about to run out of battery power will automatically shut down when, this battery is intended to be used for entertainment, therefore, need not be too concerned about, so I decided to shake the hp battery protection circuit, directly depend on BB's protection circuit. SCR is in the input and output pin (that is, cathode circuit board input and output pin) between the solder on a small 2A fuse, fuse 2A select the reason is based on current usage, the largest in the computer power consumption , the current does not exceed 1.9A, 2A capacity sufficient unusual circumstances (for example, short-circuit accident) but also to ensure that the fuse of the time, but also play a role in protection.

In fact, directly to the SCR control terminal so that it can also be a high turn-on, but taking into account the current the battery must be a reason to burn, and the reasons for the identification of protective measures taken before or better in order to avoid greater loss.

Well, the battery power has been the first non-stick, and on the machine to try it! Normal boot, plug in the power immediately after the charge on the flashing lights are up, the way when charging the battery with a random look at battery information management software, was also displayed, the battery circuit board This shows that the single chip is still working.

Batteries battery is a Panasonic, the time the factory in June 2000, the first time in October 2000, the design capacity of 38.88Wh, the current capacity 38.88Wh, is charging cycle: 0 times.

Oh, do not know how to engage in, the inspiron 1300 battery may be burned when burning confused, even cycles to the zero, Now it maybe a new battery.

Macbook Pro and powerbook G4 battery life

As regular readers will know, I own two notebooks, an original 1GHz 17″ Powerbook and a top of the Sony Vaio Z1. As we all know, the 1GHz 17″ Powerbook is based around a G4.

The PowerBook G4 gets about 2-3 hours of battery life out of my typical use. That’s with the screen turned down to an acceptable level, now DVD drive use and most of the other power saving features switched on. I’ve had better than before now, but only when I’ve gone really offline and only the machine for writing or browsing content, rather than my more usual process of browsing the Internet (which implies wireless connectivity, and more power) and recompiling lots of code.

That’s why I specified the battery time in terms of my, so as not to confuse those readers who will chime in with comments that all timings are wrong…

The Sony Z1 is based around the Centrino set and the Pentium-M mobile CPU, both these components are predecessors to the components built into the new MacBook Pro. This has far more complex power saving systems, such as the ability to switch off (rather than simply not use) the DVD drive, and even to power off the PC Cards, built-in memory stick reader and of course reduce the CPU MHz and power requirements to a very low level.

With the standard laptop battery on the Sony I get about the same period of battery powered usage as the Powerbook. It can be as high as 4 hours, but in the majority of cases a more realistic figure is about 3 hours of my more typical use.

I can slap in a larger battery (exactly twice the size and capacity) and that I can get about 6.5 hours mobile use. It does however ruin the look of the laptop, and raise the back by about 3/4 of an inch.

Now just to summarize:
Powerbook G4, 17″battery, standard battery: 2-3 hours
Sony Vaio Z1, standard battery: 2-3 hours

To get 2-3 hours (and more) out of a Powerbook is quite an achievement when you think about the Z1, which is Centrino/Pentium-M based and has a heap of power saving technology. Both are using the battery that came with the machine.

Standard laptop battery, standard machines, more or less equal battery life.

Just in case the point I’m making still isn’t clear, using the Vaio, a notebook using the previous version of ‘low power’ technology that is in the new MacBooks I get the SAME battery life as my G4.

What could I expect out of the new MacBook Pro?

I’d expect about the same as I get from the Vaio, perhaps a modest 10-15% increase based on the newer technology, but that has to be tempered by a combination of other factors, like the fact that this is a first generation item from Apple, and that we’re using newer Dual-Core CPU.

For some reason however we have a bunch of Apple commentators (I refuse to call them fans, since they seem to be doing nothing more than slagging Apple off at the moment) who seem to think that the new PowerBooks should have 5, 6 or 7 hour battery life.

Why?

Hell knows - existing PC laptops get - as my Vaio experience demonstrates, about 2-3, 4 hours tops.

Why would an Apple-built, Intel based laptop somehow defy the laws of physics, common sense and exceed the capabilities of PC laptops that have been made by manufacturers using the technology for years before Apple got to it, somehow exceed by a factor 75% or more the inspiron 6400 battery life of existing Intel based laptops?

There’s a finite amount of power you can squeeze into a battery, and there’s a limit to how much you can reduce the power requirements of a laptop.

From a first generation - and more importantly, at the moment, pre-production Apple Intel notebook I think a time of 4 hours is pretty good. That actually equals, or beats, my Vaio.

While I’d love to see Apple produce a laptop that has a longer battery life, we need to be realistic. It’s going to take Apple a while to get the best out of the hardware, and even if they do improve the battery life, they wont be the first to do so - other PC notebook manufacturers will probably get there first. Apple were one of the first 10 companies to announce a dualcore Yonah laptop battery manufacturer??, so we’re already at the bleeding edge.

Meanwhile, give Apple a break - they enough on their plate right now without people criticising them for matching or beating the battery life of their old laptops and their current competitors.
