Those looking at the ultra-portable Lenovo ThinkPad Twist might be a little confused about where segment it fits. However, ThinkPad Twist is not a normal ultrabook. The screen can rotate and turn the system into a bulky tablet. The following are our impressions about this ultra-portable with multifunctions.
When closed, the Lenovo ThinkPad Twist ultrabook brings a lot like ThinkPad Edge. The tape around the screen is glossy but does not cover the whole screen frame. The first thing that you notice when you take the ThinkPad Twist in hand is the very fine texture of the casing. The manufacturer used magnesium alloy for its construction, the screen is protected by Gorilla Glass.
Product name is inspired by the action that makes the user to turn the laptop into tablet. Special hinge of the screen is very robust and capable of maintaining the inclination. Its panel may shake less when accidentally hit the office, but there is something disturbing. The only thing that does not fit well with the overall package is the shiny plastic on the bottom screen. On the surface you can find the glossy Start button, light sensor and two buttons for volume.
I wish to say that Lenovo's ThinkPad Twist finishes are impeccable, but I cannot. On the front side of the base is a combination that clings when you pass your finger over it. Otherwise, I cannot say I found other construction problems.
Keyboard and touchpad
For those not familiar with Lenovo ThinkPad laptops, the keyboard is one of the best on the market. The buttons are large, well spaced and have a great race. Very good tactile feedback and editing documents is a pleasure. As with previous models, Lenovo ThinkPad Twist having the F1-F12 keys disabled by default. A simple touch activates the indicated function with white paint. For example for F5 you should use Fn key. The latter is located in the lower left corner, where it had to be Ctrl.
Personally I would have liked to have directional keys indicated by a small protuberance, such as that found on the F and J keys to the dismay of many, Lenovo dropped from touchpad to the separate buttons. Two-finger scrolling is inverted by default and is a function of enabled acceleration.
For ThinkPad Twist to be used in tablet mode, the manufacturer had to provide the IPS panel. He has over saturated colors and boast on paper with 350 cd/m². In practice it doesn't seemed to be so bright, which might be due to the active light sensor. The viewing angles are a little narrower than we would have expected from a IPS array.
Display: 12.5", 1366x768, IPS touchscreen, Gorilla Glass
CPU: Intel Core i7-3517U, 1.9 GHz, 4 MB cache, Turbo 3 GHz, dual core, HT, 22 nm, 17 W TDP
Chipset: Intel HM75
Integrated GPU: Intel HD Graphics 4000
RAM: 8 GB DDR3 1333 MHz, 1 DIMM
HDD: 128 GB, SSD, Toshiba THNSNF
Maybe it's not really that highlighted, but Lenovo ThinkPad Twist comes with a screen of 12.5" in a 13.3" format. Flat edges of the screen and the big space around the hinge make it even wider than an ultra-portable of 13.3". We find here a good hardware performance, at least for the ultrabook class. As we will see, ThinkPad Twist moves very well. The hard drive is SSD type, but one with platters would be protected from falling. Its housing is bolted to the chassis, HDD is Surrounded by a slightly flexible support.
In terms of performance, Lenovo ThinkPad Twist doesn't bring any surprise. The system is very fast, helped by the Intel Core i7 Ivy Bridge range and Toshiba SSD. Timed, Windows 8 Pro turns cold in 14 seconds. It is true that we have here a dual core ULV processor, but it can reach 3 GHz in Turbo Mode with a single core. Maybe it's not a perfect processor for video processing, but will easily run photo editing applications where the user reconciles with the screen resolution.
I have recently learned that Lenovo engineers prefer to build such systems with higher capacity than needed to prevent efficient reductions that occur over time. Dust and particles that are deposited on the heatsink fins can become a problem in 2-3 years, depending on the environment were the ultra-portable is used. That is when the CPU temperature does not exceed our limit of 90 degrees Celsius in 3DMark 11.
The noise of the cooling system is not disturbing. It is noticeable, but at full speed, the fan is heard only in very quiet rooms. The main problem is the location of the discharge slot. Because it can be used in tablet mode, Lenovo ultrabook could not have that slot on the rear. It is located on the right side. Warm air is immediately felt by the user when the CPU starts working hard.
Lenovo ThinkPad Twist failed to impress in this chapter. Offering a range of three and a half hours in both the multimedia test and in the office. For the test I used a multimedia movie with 720p resolution, running with the screen brightness reduced to 80% off the wireless card and a headset used to play the sound. For the office test we have drafted documents, I browsed the Internet using the wireless card and listened to music in the background using a pair of headphones. Screen brightness was reduced to 60%. Profile system used for the two tests was Power Saver.
