review of lenovo thinkpad t61
Standard aspect ratio business notebooks are becoming more difficult to purchase these days from different manufacturers, but Lenovo has pulled through for another generation with the ThinkPad T61. The 14" 4:3 T61 is one of the last models of its kind on the market, and it is still every bit as durable and refined as the models before it.
The Lenovo(IBM) T61 4:3 14.1" notebook is offered with a wide array of options, with processors spanning from the Intel T7100 to the T7800, ram up to 4GB, hard drive up to 200GB, Intel turbo memory, Intel Wireless-N, and either the 128MB nVidia NVS 140M or Intel X3100 graphics cards.

Build and Design
Comparing the outside of the 14.1" T61 to the older T60, it's hard to figure out what all has changed. One clue that may stand out depending on how familiar you are with the hinge setup, is the left hinge is wider than the right hinge. Another subtle change that many diehard Thinkpad users will notice is the sticker has changed from being the older multi-color IBM logo, to just "ThinkPad Tseries". Other than that no visible changes have been made. Internally the 14" T-Series has gained a new LCD roll cage, which helps significantly to reduce screen lid flex, and ripples from pressing hard behind the screen.
Opening up the T61 another subtle but slightly odd change is the LCD is off center. If you are really picky about that sort of thing it may drive you insane, but I didn't even notice it after using the notebook for more than five minutes.
Structure wise the notebook is as strong as ever. Just like the T61p, chassis flex is not present, body panels don't squeak under hard pressure, and palm support is excellent for typing. The palm rest has been redesigned from the previous model, but it doesn't look much different without closer inspection. The front lip overhang has increased, and tasks like upgrading ram are a bit easier, since the palm rest seemed easier to slide off and reinstall.
Performance and Benchmarks
The T61 was an excellent all around performer, without any lag or delay opening programs or switching between programs. Much of this can be attributed to the amount of ram and the 7200rm hard drive which was configured with this model. Even tasks such as light gaming were possible with its business grade nVidia NVS 140M, comparable to the consumer nVdia 8400 GT.

wPrime is a program that forces the processor to do recursive mathematical calculations, the advantage of this program is that it is multi-threaded and can use both processor cores at once, thereby giving more accurate benchmarking measurements than Super Pi.

The only weakness of the 4:3 T61 is the screen in my opinion. The 200:1 contrast ratio really shows throughout normal use, with menus and other screen objects looking washed out. Some darker screens were difficult to view, with screen elements blending into the background. Brightness levels were acceptable for a 14.1" notebook, and I found my comfortable levels to be set at about 85%.
Viewing angles were average, with the colors tending to invert quickly on its vertical axis. Horizontal angles were better, keeping colors true to more extreme angles. Refresh times were also about average, with items like the mouse cursor showing some faint trailing on quick movement.
Keyboard, Touchpad, and Fingerprint Reader
The keyboard hasn't changed much, in fact it is the identical part number to the one found on the older T60. This is great news for those hoping that the trusted layout and feel stayed the same into the new model. Same goes for the touchpad and fingerprint sensor. With many keyboard reviews, you generally see that particular model being compared against the "ThinkPad Keyboard" and this really holds true. You can type comfortably for hours at this keyboard as if it was your desktop in front of you. The support under the keyboard is very sturdy, with absolutely no flex anywhere.
The touchpad, while being on the small side compared to versions found on other laptops, is still easy to operate. I find the semi-rough texture to be preferable to a polished feel for better control, and it seems to hold up longer to oils on your finger without getting too slick. The Trackpoint hasn't changed much over the years, and gives the same feel as it always has. The buttons for both the touchpad and trackpoint give a nice solid clunk when pressed, never needing to be forced to register the click. The fingerprint reader works great, although in general they take a while to get used to the swiping motion. If you have never used one before, it may be a few days before you get the single stroke login down pat.
Input and Output Ports
The speakers on the T61 (as with the previous ThinkPad models) are slightly below average. With the speakers pointing directly down on the lower edge of the palmrest, sounds were muted slightly. If you had the laptop on a soft surface like a bed, the speakers would be completely blocked. Peak volume levels were lacking for loud movie entertainment, but the headphone jack was an acceptable alternative. Sound output was clear and free of any hiss or other interference. A coax digital output is also available through the advanced or advanced mini dock for connecting to your home stereo.
This T61 was configured with the Intel 4965AGN wireless card, and in daily use it worked without any problems. Reception was always strong and clear if you were within reasonable range of the access point, and it never had any odd dropouts that would kill a long file download. Wired performance was also excellent with the onboard Intel gigabit interface, never giving any hiccups.
Heat and Noise
The T61 managed heat much better than the older T60 under normal use. In situations where the CPU and/or GPU would be close to an idle state, heat was dispersed passively through the chassis and keyboard with the fan turning on in small intervals. Under heavier loads the fans would come on more, but temperature levels stayed in acceptable ranges. Fan noise was minimal, with the 7200rpm drive almost always louder.

Battery Of IBM (Lenovo) thinkpad t60
The 9-cell battery on the T61 got just over 4 hours and 30 minutes in testing, with screen brightness at 80%, CPU set to adaptive, and with light internet activity. This was a bit less battery life compared to my 15" T60 running XP, but the key difference seems to be that Vista is slightly more intensive in background activities. For in-flight entertainment, the T61 should be fine for getting through an entire DVD movie.
Being one of the last 4:3 notebooks on the market today, the Lenovo T61 is a clear winner for those who still haven't adjusted to the widescreen format choices. It offers a ton of power for the demanding business user, and you are still able to get most of the features available to the widescreen T61 models. Overall it's great to see Lenovo still notebook format as an option to its customers.
