Original owner. Purchased as an unused, unopened fleet laptop. First powered on less than two years ago. I upgraded the RAM from 4GB to 8GB (single module only) and replaced the hard drive with a 240GB SSD. I also purchased the secondary, internal battery separately and installed it. While I had it open I replaced the thermal paste. It is very snappy with Windows 10 (currently installed) and can run Ubuntu perfectly (tested before the Windows install). It traveled with me one time on a plane and was on a desk when in use, but it spent most of its time on a shelf in the closet powered off. It is a solid computer I just can't justify keeping it stored away when it could be in the hands of another user.
