The Lenovo ThinkPad X61 is an ultraportable business laptop geared to individuals who demand the best. Like its larger brothers of the ThinkPad line, it shares all of the same rugged features, as well as the creature comforts of a full-size keyboard. The X61 looks as if Lenovo took a ThinkPad T60 and shrunk it down by 30 percent. Although it is much smaller than its counterparts, it is every bit as fast. This model came loaded with a 7200rpm hard drive, 2GHz Core 2 Duo processor, and 2GB of RAM. Light business travelers can rest easy knowing they didn’t sacrifice anything but weight when they bring the X61 on the road.

Design and Build

The X61 is a durable ultraportable computer. It shares many design characteristics with the rest of the ThinkPad line including its internal unibody structure, full-size keyboard, stainless steel display hinges, and complete port selection. The fit and finish is astounding, with no creaks anywhere (not even a small creak), as well as little unused space. The outside case is very strong giving it a good deal of protection when thrown into a briefcase or maybe even a tall purse. It really seems like a handbag sized ThinkPad down to the smallest detail.

For upgrades and repairs that might come up down the road, the X61 has the user in mind with easy to remove access panels and covers. The most frequent upgrade items being the HD and RAM are accessed through panels on the bottom and side of the X61. Other items such as the keyboard, wireless cards, and backup battery can be reached by removing a handful of labeled screws on the bottom, and easily popped out. For my first time taking it apart it took roughly three minutes to figure out how the panels came off once the screws were out. I found almost little to no risk of breaking other components during this process, unlike other laptops which are not so user friendly in this area.

One concern worth mentioning is the amount of heat that can build up below the palm rest after the computer has been powered up for about an hour. The right side was fairly warm to the touch, and when I took the laptop apart to find the cause of the heat, I found that both the WiFi and WWAN cards were directly under this area. Lenovo includes an additional fan with models equipped with the WWAN card, but this may not activate if the card is not in use. During my testing, I was only using the WiFi card for internet access. Since items are packed quite densely in this ultraportable laptop, it is hard to win on all design points.

Keyboard and Touchpoint

The most surprising thing about the 12” X series laptops is it has a “full-size” keyboard. The primary letters, numbers, and function keys are all the same size as the larger 14” and 15” models, with only the outer keys reduced in size. This gives you a comfortable typing surface, that once you get used to the odd size outer keys, becomes a pleasure to type on. Build quality is 2nd to none, and it shows with the very precise quiet clicks that each key press gives as feedback.
The touchpad or lack thereof will probably come as a shock to most users seeing only the red cap of the ThinkPad Touchpoint. To save space the X61 omits the touchpad system in favor of a touchpoint. I never really used the Touchpoint on my T60, falling back to the touchpad on almost all occasions. Even so I found transitioning to the Touchpoint to be painless, and I even found myself using it on my T60 without realizing it. The only problem that did come up is occasionally the pointer would start to drift without any input from me. I had to tap the Touchpoint a bit to make it stop. This may be a result of the fine sensitivity I had it set to, but it was hard to duplicate the problem enough to pinpoint the cause.
The screen lacks defined blacks and good contrast. Vertical viewing angles are not that good -- quickly inverting colors at the slightest change of angle from being perpendicular to the screen. Since this laptop will be close to you during normal use, this shouldn’t be too much of a problem. I found the brightness of the screen to be pleasant typing indoors, although it would be quickly washed out outside in the sun. For normal use inside, my comfortable viewing level was six or seven notches down from the max of 15.

Protection from the display cover is very good, requiring a ton of pressure before you start seeing any ripples on the screen. The hinges are strong, but they don’t feel as tight as other ThinkPad models. Normally it requires two hands to open up the display of a ThinkPad, but the X61 only requires one. Given that the hinges are so much smaller on this model, it could be that they have a much smaller friction surface.
The screen on my X61 had no defects like dead pixels or backlight leakage.
The speakers inside the X61 are very weak, and I would have to suggest wearing headphones for watching movies. For better speaker performance, the optional X6 base provides much better sound quality. The differences between the 2 systems are pretty amazing. Playing music outside of the dock sounds like headphones with the volume cranked, then when docked it sounded like a boom box.
The X61 is very impressive when it comes to raw power in such a small package. As the following results show, it provided some very respectable benchmarks. Overall I think the 7200rpm hard drive provided the biggest benefit, giving it instantaneous load times. Windows Vista startup time from the moment I pressed the power button to no activity on the desktop was 46 seconds.

I found the battery life to net between four to five hours of use on the 8-cell extended battery. With Vista the system likes to occasionally go wild in the background almost pegging the processor, eating up precious power from the battery at times. I also had problems with the ThinkPad power management software competing against Vista's power management settings. After every reboot settings such as HD spindown, standby, LCD shutdown, etc. were all changed back to the default Vista settings. Even though I had the Vista and ThinkPad settings both set to “Never” for every power option, it still returned to 5-10 minute intervals after every reboot. I found myself returning from a coffee break to the computer shutting itself down, only to have to spend another minute powering it back up. Compared to Windows XP, Vista has been horrible in my uses for power management or power efficiency. It was hard to ever have a moment just sitting where the HD didn’t start seeking like crazy, or the CPU going under load wearing the battery down.
When compared to other Lenovo laptops, the X61 recharges its battery extremely fast. I could easily say it was between 30-50% faster than my T60 trying to charge, especially as the battery got to a higher charge level. Around 90% the T60 slows down to about 40-50 minutes left, but the X61 takes 15-20 minutes from this point. Both systems were using their respective extended batteries, which were around the 80Ah capacity.
The power adapter is 65w model, measuring 4.134” x 1.709” x 1.138” and 8 oz in weight. This was small enough to not add any real bulk to my carrying case, a great pair to the X61.
Heat and Noise
Heat output from the laptop is more than you would expect from such a small machine. Unless idle, the laptop usually had its fan spinning at a low speed outputting a fair amount of heat. Fan noise was minimal though, so when its one you may not notice it.
The palm rest was also another heat source, with both wireless cards mounted under the right side. After being powered on for 30-40 minutes, the right side gets pretty warm. With a room temperature of 76F, the right side of the palm rest was measuring 97F, with the rest of the laptop around 90F. If you were typing for a couple of hours, your wrist may start feeling some discomfort from the heat.
This X61 was equipped with the Intel 4965AGN, and reception through the laptop was above average. The Atheros alternative (ThinkPad 11a/b/g) which I have in my T60 did manage to pull in wireless networks that the X61 could not see, and may be a better option if you are customizing it on the Lenovo website yourself.
I wasn’t able to fully test the built-in Verizon wireless WWAN card since I don’t have that service, but I did check its reception in my house. Usually cell phones barely work and cutout frequently. The X61’s antenna saw a 30% signal, and didn’t seem to change if the antenna was fully seated, or extended all the way.
I found the ThinkPad X61 to be a fantastic alternative to my larger 15” T60 in situations that I didn’t want to lug around the heavier machine. It had all the grunt of the much larger machine, but inside a much smaller package. I was also surprised by how easy it was to upgrade the ram in the X61, by removing a access panel on the bottom of the laptop. This is the only ThinkPad that doesn’t require you to remove the palm rest for this upgrade. Besides the screen, the only qualms I had with this laptop related back to Vista. For the ultimate travel machine, I personally would install XP Professional on it for better battery life.
