Thinkpad T61 : update to the T60

ThinkPad T61 and the ThinkPad R61 are the Lenovo Centrino laptops. They are so similar that you cant differ them only by their physical desigh. The thinkpad T61 is the update of Thinkpad T60: 14-inch models include all the important parts of Intel's revamped Centrino platform, including new Core 2 Duo CPUs, extra onboard Turbo Memory (for boosting access times), and 802.11n Wi-Fi.

The ThinkPad T61 continues the T-Series tradition of being thin and light enough to carry around with you all day - 336 x 237 x 28mm (WxDxH) and 2.3kg - but still maintaining a decent size screen and keyboard. In fact, whenever I've been asked what my favourite ThinkPad model is, I've always been torn between the T-Series and X-Series, with the latter being smaller and lighter, but also less feature packed.

Specs

• Processor: Intel T7300 Core 2 Duo (2.0GHz, 800MHz FSB, 4MB Cache)
• Graphics: Intel GMA X3100
• Operating System: Windows Vista Business

• Memory: 2GB (1GB x 1GB), up to 4GB max
• Ports: 3 USB 2.0, 1 FireWire, Monitor out, modem, Ethernet, headphone out, microphone in
• Slots: 1 PC Card Slot, 1 ExpressCard slot (optional media card reader and Smart Card reader)
• Optical Drive: Ultra-slim Super-Multi Drive

• Weight: 5.1lbs
• Battery : Thinkpad T61 battery 6 cell.

The new CPUs from Intel, including the T7300 in the ThinkPad T61, all include some power saving and performance boosting features. One feature is called Enhanced Dynamic Acceleration, which will power down one core of the CPU when it's not needed, and use some of the power saved to boost the still-active core, giving it more speed. On top of that the FSB has been increased from 667MHz to 800MHz, providing more bandwidth and faster communication between the CPU, the memory and the chipset.

New switchable graphics, LCD backlit displays, and DisplayPort technology features give you superior graphics performance on your ThinkPad T Series notebook. Experience brighter, crisper colors and lower power consumption life with the new LED backlit displays on the ThinkPad T Series. These new displays are bright without sacrificing battery life, with 25% brighter displays and using 2W less power than conventional CCFL displays. These high-resolution displays also contribute to the thin and light design of ThinkPad T Series notebooks, weighing 70 grams lighter than conventional displays. Users who travel frequently will appreciate the wide dimming range of the LED backlit display. This allows you to reduce brightness while still experiencing a crisp, comfortable display in dim environments such as an aircraft cabin. Finally, to protect the environment, our LED backlit displays are mercury-free.

One major feature the Centrino Pro ThinkPad T61 has over the Centrino Duo R61 is the inclusion of Intel's Active Management Technology. You get a faster processor front side bus (800MHz), more processor cache (4MB) and an improved integrated graphics solution in the form of the Intel X3100. If all that talk is nonsense to you, then suffice it to say the T61 offers newer and better processing components than the T60.

Battery Life : Thinkpad T61 battery is 6-Cell battery. It can last about 2 hours 15 minutes, check the reduce screen refresh option and you can gain a couple of minutes of battery life, and the interface will show you that approximation. But you d better buy a cheap thinkpad T61 battery replacement in www.laptops-battery.co.uk. The Thinkpad T61 battery also fits for thinkpad R61.

Compare with the prev Thinkpad T Series laptop, The T61 has following advantage

• LED backlit, mercury-free displays
• Dual-core processors consume 10% less power than standard-voltage processors
• 25% cooler and quieter than previous T Series
• Switchable graphics feature uses 15% less power than previous T Series
• SSD drives use 90% less power than standard hard drives
• Low-wattage processor technology (25 watt processors)
• Battery Stretch feature extends battery life and reduces waste
• Reusable packaging is designed for minimum 5 reuses
• Energy Calculator enables you to calculate power savings for your system configuration

In all the ThinkPad T61 Widescreen is the latest in Lenovo's ThinkPad T-series of world-class laptops that have stood the test of time among corporate professionals. But the transition is now complete - the T61 is the first ThinkPad in PC Pro not to feature the IBM logo at all - and we're relieved to say that the ThinkPad range is none the worse for it.
