The ThinkPad X1 looks to be the next laptop off the Lenovo production line after a PDF intended for internal eyes only revealed details about its key specs.
The ultraslim notebook is set to host new battery technology that will help the X1 last three times as long as a typical notebook battery.
RapidCharge technology will also apparently help the laptop charge 2.5 times faster than previous ThinkPad batteries, charging 80% in just 30 minutes.
Previous leaks suggest the X1 will feature a 13.3-inch Gorilla Glass screen with 1366 x 768 resolution, 2.5GHz Core i5-2520M CPU, 160GB SSD and will be just 21.5mm thick.
Revealed alongside the already shipping E420S and E220S laptops, the document also interestingly mentions something called a X-Slate but includes no further details to identify exactly what the X-Slate is. Lenovo tablet anyone?
