Hi all, I have an iBook g3 running Tiger that I bought second hand almost two years ago that has been working perfectly up until yesterday. I use it for uni during the day and usually turn the machine off overnight while it charges. The other night I left it 'asleep' while charging instead of off. When I came to use it in the morning it would not wake up and was totally silent although it's pulsing 'on' light in the front part of the casing was on. The charging cable was still connected and was green, indicating a full charge, but the battery-life light display, when pressed, showed only a single light, which flashds a few times, indicating the battery wasn't fully charged. While trying to get the thing to do something I removed the battery. This caused the ibook to turn off the pulsating light - it was completely off and apparently not drawing power from it's adapter, which was still plugged in. I have been trying since then to get the computer to turn on. No matter how long it is left charging, the battery never indicates anything other than a single light with a few flashes, the computer will not turn on and the cable of the charger stays green when plugged in. I have tried inserting an older battery - which I know worked, it just only used to hold an hour's charge or so - and it will not charge at all. I have also tried resetting the PMU, which appears to have done nothing Does anybody know of anything else I could try? Thanks for any help.
