It's largely turned into a doorstop after the battery was dying a year or so ago. I bought a $70 battery from a random seller on advice from a friend who had good luck with fit and instructions. Replacement was a breeze, and it seemed great at first, but pretty quickly started just dying on me. I use the laptop so rarely, it just seems like, no matter what the SOC was last time I used it, next time I pick it up (usually a week or more later), it was dead and needed power.

that said, about a year or two ago was also when it just started feeling too slow to be usable (beachballs all the time). I blame web bloat, mostly :-/

I bought it new, so I definitely got my money's worth out of it.
