About My Lenovo
I have a Lenovo ThinkPad E540 model 20C6008QUS (Core i7 processor, Intel video, 500GB hard drive, came with 4GB RAM, came with Windows 7 and disks for Windows 8). I purchased it in January 2015. I upgraded the RAM to 16GB, and I was considering an SSD but haven't ordered one yet.
I run Ubuntu 14.04 on it -- I tried Ubuntu 14.10 and it doesn't run so well. I've only booted Windows 7 in order to upgrade the BIOS.
