Great PC.  Looks great and performance is great for an older top tier business class PC.  This is the second of this model i bought refurbished.But following the recommended battery calibration procedures included with this PC damaged the battery such that it will not charge above 93% anymore. Limiting the battery life before getting much use from it!  Very disappointed in seller for recommending this procedure. And feeling very dumb for following it in the first place (I have never had to "calibrate" a laptop battery before.)
