A few months ago, we took a look at what was then the latest ThinkPad offering from Lenovo, the X220. Based on Intel's second generation core processors, this system was consistently a classic business-oriented ThinkPad. A few months before the X220, I had the IdeaPad U260 in my house, which Lenovo classified as a “thin, light and stylish travel companion”.
I mention these two units as a transition to what we have for review today, the new ThinkPad X1. As the thinnest ThinkPad of all time, the X1 apparently takes the best features of the X220 and U260 and merges them into one. The result is an extremely thin and slim 13.4-inch notebook that is a real successor to the X300 series that many owned and love a few years ago.
The ThinkPad X1 offers a lot of features and powerful hardware in a thin frame. It's interesting to note, however, that the X1 lets go of some key features of the X300. Lenovo has switched to an internal, non-removable battery and removed the optical drive. In true Thinkpad fashion, however, the X1 retains a rugged design and an internal roll cage. For the first time ever, Lenovo has also added a chiclet-style keyboard that is both splash-proof and backlit.
The ThinkPad X1 device we sent is equipped with a dual-core Core i5-2520M clocked at 2.5 GHz. This is the same four threaded processor we saw on the X220, which also has Intel HD 3000 graphics for a maximum TDP of 35W.
Additional hardware includes 4 GB DDR3, a Hitachi hard drive with 320 GB and 7200 rpm, Intel Centrino Advanced-N 6205 Wireless, Bluetooth, an internal 6-cell battery (38.92 Wh) and a 13.4-inch TFT display with a resolution of 1366 x 768 Corning Gorilla Glass. Our tested weight is 3.73 pounds with dimensions of 13.26 "x 9.1" x 0.65 "- 0.84".
With the exception of the internal battery, the hardware specifications are practically identical to those of the X220, although you can configure the processor, memory and hard drive exactly to your specifications. We also received the optional external slice battery, a 6-cell unit (35.5 Wh) for extra runtime.
