Bought this computer as a refurbished item. Had it for a few months before it started dying on me. I then realized it was dying on me when it wasn't plugged in even though it said battery was at 100%. By the time I realized it was a problem with the battery the return window had closed. I just replaced the battery myself and it seems to be working without the need for being plugged in. The refurbishing process wasn't very thorough.
