[QUOTE="gbr80, post: 1598831, member: 196197"] The battery's been fine up to now, unfortunately I can't tell you cycle counts as I can't get into the utilities. The AHT extended testing also showed no trouble. It will currently charge no problem, and the charger is fine. I've just swapped out the HDD for a different one with a working OS on it from a similar model - the screen backlight now comes on, but now with no chime... [/QUOTE]
