Lenovo ThinkPad T400s Touch
The multi-functionality is one of the new features added to laptops and tablet similar. Tablets currently offer only the manipulation of screen objects, while the portable multi-touch is limited by the touch screen. Lenovo hopes to change that with the addition of multi-touch screens for thin and light Lenovo ThinkPad T400. For $ 400 more than the T400 base, users benefit from a touch screen, even if a non-pivot. In this review, see the new T400 Windows 7 touch and see if you can actually find an increase in productivity.
Construction and Design
The new dell latitude e6400 battery seems completely restored and polished than normal T400. The chassis has been lightened considerably and the weight of the laptop also fallen by almost a pound. The exterior paint is still wrapped in black rubber Lenovo beloved, but the project seems cleaner and less crowded than previous ThinkPad models.
Inside, the major changes that become apparent. In addition, the new keyboard and touchpad to move quickly, Lenovo wrist rest changed your way around the touch screen, touch the color screen off the palm rest, instead of just "the collection. The framework the screen is smooth along the perimeter of the screen, unlike the T400 displays plastic panels near the antenna and cut close to the light and a camera. Even compared to the X301 ThinkPad T400 new look more refined. The speaker grilles are larger and resemble more appropriate for design. The fingerprint reader is able to blend in better with a design in black instead of gold and silver than previous models.
The build quality is always fantastic, with a hint of chassis flex even decreased in thickness. The screen has a low bending from left to right when opened, but no more than previous models. Protection for the screen, even with super-thin cover is surprisingly good, showing only small amounts of distortion of the screen when you press the back of the screen. The new chassis is very robust.
With the Lenovo Slim redesigned the chassis of the T400 and T400 is completely different from that, once you start to open. The hard drive is now accessible through a panel on the left side of the palm support, which is now 1.8 "instead of 2.5" found in the dell c1295 battery. System memory and wireless cards are a unique access panel on the underside of the laptop. In comparison with the elimination of support for palm in previous models, now simply unscrew a screw and a panel context memory single update. With most sites to change the position on the bottom of the laptop, removing the keyboard is now only necessary to replace a broken one, or to access the half-size mini-PCIe slot for USB Wireless wire is used in some models. I really hope that the future ThinkPad follow a similar design to the T400, it is much easier to upgrade components now.
Screen and speakers
The T400 uses a touch screen similar to the regular T400, but with a touch of the screen surface. Everest is the number of the panel that Samsung has made a device with multitouch N-Trig LT141DEQ8B00. As usual T400, the screen has a resolution of WGXA + and is backlit by LEDs. In general, the screen is almost identical, but a defect it shares with most touch screens. Touch screens seem to have a layer of fog on the screen, but the T400 is not so obvious. Users who have never seen a laptop from one side may not notice the difference, but if you come from a normal cell can be a bit "boring. Color and contrast are good compared to the activity of pocket, but what seems to wash with the best and brightest of the laptop big screen. The levels of backlight is strong, my preferred setting is 50-60% in my house and about 75 % in the office with the bright light. The backlight bleeding is minimal, just passing through the highest levels of brightness.
The contact area is a unique feature for a laptop. On the one hand we can directly manipulate objects without using the mouse or the touchpad, but on the other side has a fixed screen that can rotate as a tablet. Another inherent flaw of multitouch is already using the finger as a pointer, that will never be more accurate and precise as a pen input pad. This means that the controls are at best crude gestures or Database Command Reference. In this area of multi-touch screen works very well. The move is the web site easily with a finger, but sometimes, the monitor detects two voices and began to enlarge the page. While the drawing of circles, we noticed some problems with our pre-screen production in some parts of the panel would be nervous, instead of displaying the soft lines. As our model is very early in the panel would be safe to say that the production models would not have this problem.
Performance of the speakers was mediocre but that is common in business laptops. They work well for streaming audio or VoIP have a conversation, but for movies and entertainment in the headphone jack is a much better alternative.
Keyboard and Touchpad
Yes, Lenovo dramatically changed the look and design of the keyboard on the T400. After obtaining the floor of the unconscious, it is easy to see most of the changes for the better. The sense key is kept intact in most models of the past ... Besides the fact that the space bar appears, click aloud if the press along the edges. The biggest change was a function of the new design, offering more "escape" key and "delete". Lenovo thorough search revealed that two keys were used in the function keys. As a result, doubled and moved to the position of the input and the F1 key.
I think the best difference is the new buttons in the media and the power button. The noise and light up when the switch is activated, so instead of showing the power icon in the bottom of the screen, the same button is the indicator. The Caps Lock key is now a transparent window with LED lights to indicate Caps Lock is on. One thing missing is a lamp and battery with the screen open, as they are now outside.
The lenovo t400 battery has a feature not yet seen any other laptop to date: a speaker and a microphone button. Although I'm not sure how many times the staff to turn off the microphone, Skype or video conferencing if the frequent use after a touch of silence would be useful. Another small change is the key to the reduction of tolerance, which means there is less space for crumbs and dust from falling between the keys.
The touchpad is different, but I'm hard to know if it's good or bad. The project uses a slightly rough old opaque plastic, which gave some traction and has made it easy to move your finger around the sweat. The new design has raised dimple finish with a soft texture that feels weird. I found the increased sensitivity in the Synaptics control panel to feel the movement more fluid, but deemed too sensitive. It seems to be necessary to apply constant pressure as it moves across the touchpad, new where it was easy to flick your finger. I think if the bumps on the track was slippery and could use more light.
Another change is the shape and size of buttons on the trackpad. The keys have a beam passes through the edge of the buttons at the ends where they meet the palm rest. From the perspective of the design to improve traffic flow with the laptop than previous attempts, and is now even easier to access the touch screen.
Ports and Features
Port selection on the T400 is much better than the T400 model. New on the back of T400 is an eSATA port for memory expansion and DisplayPort output, which provides digital video of the laptop. Like the T400 has three USB ports, one with a combo USB / eSATA. Lenovo has maintained the VGA port for connecting legacy, as is still often used to the spotlight. With decreasing the thickness of the double slit T400 lost, leaving only an ExpressCard/34 slot. The T400 has a dock connector on the bottom, but it is a new design that is not compatible with older models. The big change came with the T60 final, and I can only hope that this format is the cradle of the same for generations to come a couple of laptops.
Performance
The Lenovo ThinkPad T400 Touch is the first "official" Windows 7 laptops that we had during the examination. This means that all the appropriate drivers from the manufacturer, and the new utility designed for Windows 7. In most of the dell latitude d630 battery that we have personally examined the upgrade to Windows 7, we saw decent performance hit, but it was not the case with the T400. Since the first review, the only elements that have changed the operating system with touch screen, SSD advantage, and RAM, which is now twice the size of 4 GB. All aspects of daily performances seem very agile, including startup time, application loading and playback of HD movies. When we went to a synthetic test of its performance, we conducted fairly drastic PCMark05 success and the success of a few "small wPrime. 3DMark06 is the only reference was increased. Some of these drivers can be linked, because Windows 7 is technically not officially released, but it will still against what we have seen on other computers. Otherwise, the interface is electoral actions, and with precious CPU cycles. The average user is not aware of this, because you can not see any drop in performance in using every day.
Heat and noise
We found the T400 Touch ran a little "hotter than the T400 series in our tests. Meanwhile mobile areas showed the same warmth, the touch T400 was 3-4 degrees warmer in each area. Some of these can be related to temperature, or may be related to certain components to be able to run hotter or faster on Windows 7, while a moderate load. In general, it did not work too hot to not to use, but it was a surprising discovery. The fan noise was similar to the standard T400, stay out of most of the time, only to come apart, while the reference point or a slight cooling internal components. Temperatures listed below are in degrees Fahrenheit.
Battery
Battery life was a surprise for the fujitsu lifebook t4215 battery. Even with the additional consumption of the touch interface, which is able to get a better battery life than non-touch version. In our battery test with screen brightness at 70%, wireless active profile and balanced system, which was 6 hours and 19 minutes. The T400 series has managed only five hours and 48 minutes under similar conditions. This could be one area where Windows 7 shines with a background process on a more efficient use of the processor. These two stages are much smaller than the T400 with long battery life, however, reaching almost 10 hours with the extended 9 cell battery.
Conclusion
The Lenovo ThinkPad T400 Touch is very cool, so the key of a standard laptop. It offers users the ability to interact with the computer of a potential much more natural and huge CAD applications or even play a little "while browsing the web. The only problem I see now that it has entered in a model is already expensive, is to put beyond the reach of most users. Adding to the base of T400, from $ 749, instead of the T400, which starts at $ 1599 would be the best option. In addition to some peculiarities of the pre saw it was a good application that does not even affect your life. If you are looking for the T400 today, and could increase the budget of $ 400, it might be interesting to add to your notebook for future use.
