Full-sized and spill-resistant, the legendary ThinkPad ergonomic keyboard is renowned for its full array of keys, excellent feel, and TrackPoint® pointing device. And now it's optimized for Windows 8 with convenient multimedia buttons, function-lock capability, and immediate access to view apps. Plus, a larger, smooth TrackPad with 5-point click integration can be configured multiple ways through Settings. E531 includes numeric keypad.

|BIOS/(U)EFI||Yes/Yes||Both are working fine with Ubuntu|
|Graphics Chip||Yes||Use Prime, if you got an NVIDIA Graphic Card|

|Fingerprint Reader||No||Only thing that's not working|
|Docking Station||Partial||Everything works, but the Ethernet port|

I'm running this Laptop with Ubuntu Saucy & Trusty and everything is working out-of-the-box.
If you don't want to use the NVIDIA-Card deactivate it in the Bios, it doubles your batterylife.
If you want to use it, follow this instruction to get a nice switch.
I recommend to install the root and the home partition onto the SSD, placing the whole home-directory onto the HDD will cause programs to open slower. Some Versions don't have an SSD. The build-in SSD has a special Lenovo format.(At least in Europe, it is very hard to get one, so make sure it's already build in.)
TLP pushes the battery life for at least another 30min extra power, by the default configuration.
If you are using Saucy or below you might also want to trim your SSD.
I recommend this Laptop for a Linux-User because everything but the Fingerprint Reader is working out-of-the-box.
