The T61p is the first widescreen ThinkPad mobile workstation, and the latest high-end offering from Lenovo. It comes with almost every feature a demanding business user could want, and is starting at a very reasonable price point below 1400 for the 14.1” model. This model has also gone under a number of changes from the previous generation, and in this ThinkPad T61p review you will find out how it stacks up.

The ThinkPad T61p comes in two sizes, one being 14.1” and the model being reviewed at 15.4”. The key difference between both these lines, besides screen size, is the memory size of the NVIDIA Quadro FX 570M video card included with the system. You receive a 128MB card in the smaller 14.1” model, and double the memory at 256MB in the 15.4” model. The processor selection is the same, spanning from the Intel T7100 to T7700, memory from 1GB to 4GB, and hard drives from 60GB to 160GB in 5400 or 7200rpm flavors. Other options include a fingerprint reader, Bluetooth, Intel Turbo Memory, N-wireless, and an extended battery version.
The following are the features of the 15.4” T61p being reviewed:
Build and Design
I’ll have to admit, as a current owner of a ThinkPad T60, I was quite eager to see what had been updated and changed with the T61. The items that gained the most attention out of the box were system operating temperatures, as well as the new LCD cover construction. Lenovo had advertised both items on how they were improved across the board, and I wanted to see just how much.

Starting off with cooling system changes, I turned on the laptop and opened up tpfancontrol to watch the internal temperatures. CPU temps were very similar, but compared to my T60, GPU temps were 15-20C lower at idle! Obviously something changed under the hood of the laptop besides the wider heatsink grills. To take a closer look, I removed the keyboard from both machines, and compared the heatsinks side by side. The fan structure and CPU pad are quite similar, but the GPU/Northbridge side changed quite a bit.
A look at the GPU and cooling system (view large image)
Key parts changed:
All these changes account for the dramatically lower GPU temps at idle, even with the higher-end GPU that T61p has in comparison to the T60. Below are some figures clearly showing the differences in temperatures across the board.
When the GPU was put under load, the playing field evened out. Both laptops have roughly the same size heatsink/fan meaning they will dissipate energy just at roughly the same speed. Both laptops had GPU temps peaked around the 80-81C range, with the T61p slightly higher (though it's a much better card than the old X1400 in my T60). Another aspect some might notice is how quiet the new T61 series is under load. At first I was thinking it was a new fan design, but playing with tpfancontrol I noticed you only have 3 fan speeds instead of 7 on the T60. It is quieter under high load because the fan is limited to ~3300rpm, whereas the T60 can go upwards of ~4300rpm. Less noise yes, but also less peak airflow. Speeds 1-3 are roughly the same noise level, but the T61 (with its newer heatsink design) spends more time without the fans on at all.
The LCD cover was also changed on the T61, going from the stamped magnesium piece, to plastic. I am happy to say that not only is the plastic lid just as sturdy, but it has much less flex than the older cover. New on this model was an internal magnesium framework behind the screen for support, and this has obviously helped out a lot. With the old design, although it protected the screen just fine, you could still flex it in if you pressed hard enough with your thumb. On the new design, the internal framework supports the lid completely, preventing almost all flex.
For those curious about items that didn’t change, the AC adapter, battery, and keyboard are the exact same parts found on the previous 15” T60 and Z60m/Z61m. Keyboard is tried and true, and you don’t have to worry about replacing your spare power cords, batteries, or even the docking station.
Performance and Benchmarks
With the broad range of Core 2 Duo processors available, combined with the NVIDIA Quadro FX 570M graphics, the T61p doesn’t fall short on performance. Even with its being targeted towards business applications, it has more than enough raw power for the latest games. Another fun fact for those curious about the video ram configuration, you will be happy to know this laptop has GDDR3 modules, Hynix hy5rs123235b to be exact. To keep system lag to a minimum, this particular configuration also had a 7200rpm Seagate hard drive. The following benchmarks are a testament to this business laptop’s shear power.

Windows Vista Experience Index:
The WUXGA high resolution screen that comes standard on the 15.4” T61p has a very good contrast, and plenty of backlighting. I found the screen to be very easy to read in bright rooms and even outside. Direct sunlight does wash out the screen, but short of a perfect reflection off the screen it is quite readable outside. On higher backlight settings some mild backlight bleed was visible on a completely black screen. Viewing angles I felt were lacking, as colors washed out with vertical movement up or down. Horizontal angles were better, with little color distortion as you moved towards a steeper angle. Those who are worried about the off center screen causing viewing problems; I didn’t notice it once I started concentrating on what was on the screen. If that type of thing bugged you, the matte black finish, squared edges, and industrial looks would have turned you off well before that wider bexel on one edge. Overall the screen was fine for normal use sitting in front of the laptop, but deep down inside I wish some screen manufacturer offered a Flexview screen in this format.
One problem that wasn’t directly related to the screen itself was my eyes viewing the extremely fine resolution. This is a more personal preference than anything, and I would highly suggest that you find a 15” WUXGA screen to play with in person before you make the purchase. My preference is the lower SXGA+ (1400x1050), or SWXGA+ (1680x1050) resolution range for the 15” screen size for ease of viewing.
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. The semi-rough texture I find to be preferable to 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.

Audio and Speakers
The onboard audio on the T61p is more than adequate for mild entertainment while traveling, or listening to music in a smaller room. Don’t expect much in terms of bass and midrange from the speakers, and you won’t be disappointed. They provide more than enough volume for most tasks, but don’t compare to the speakers found on some of the media center laptops. The external headphone/speaker jack gave clear and hiss free sound, and had plenty of power to drive a larger set of headphones.
The T61p comes with Intel gigabit wired networking, as well as your choice of 3 wireless card offerings and a Bluetooth option. This configuration had the Intel 4965AGN card, but an Atheros based 11a/b/g card, as well as the Intel 3945ABG were also options. I had no problems connecting onto networks promptly, and configuration was easily controlled through Windows Vista. I had no problems connecting with “Very Good” signal strength anywhere around my 2500 sq ft brick house, with the Linksys WRT54g located in a central point. The Bluetooth transceiver was plug n play with all accessories I had laying around, although a few items were strict about using the MS Bluetooth stack or the Widcomm stack.
Heat and Noise
The T61p 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 heat would still stay in acceptable ranges. Fan noise was minimal, with the 7200rpm drive almost always louder. Specific idle and load temperatures are listed in the “Build and Design” section above.
Off the grid users would be strongly recommended to look into the 9 cell battery for the T61p. With its beefier configuration, it has a tendency to suck down power at a greater rate compared the standard T61 or T60. While my old 15” t60 w/ t7400, x1400, 2gb, and 120gb 7200.2 can string out more than 5 hours on the 9 cell, the T61p comes in below 4 hours running in balanced mode with 50% backlight. It hit 5% on the battery gauge after running for 3 hours and 33 minutes.
Starting at around 1500 for the 15.4” version, the ThinkPad T61p is a great value. With many configurations possible depending on processor speed, ram, hard drive size, operating system, security features, and battery sizes you are bound to find a setup perfect for your needs. This machine offers high performance for both business and leisure (gaming) uses, without sacrificing any of the build quality of previous ThinkPad models. Platform updates from the T60 series seem to all be for the better, with other trusted components staying the same. Overall I find the T61p to be an excellent choice for almost any situation given its midrange price point.
