i have a Clamshell iBook that until yesterday had a perfect battery but it now charges only to 27% what should i do? i have tried the battery reset apple application Battery reset 2.0. Thanks
It really does sound like a dead battery, but you could try a calibration and PMU reset all the same. If I'm right, then these techniques might make matters slightly worse. Of course, if I'm right then it also means the battery won't be lasting much longer anyway.
I tried the PMU reset and followed instructions from the site but now the iBook will not recognize the HDD or CD or Firewire Drives attached to it and i get an infinite question marked folder then it goes to the Face on the folder then back to the question mark and does this repeatedly.
If you can't boot from the OS discs, then you might need to have that thing looked at. Is there another battery you could try it with? It seems odd that it lost its start up drive after the PMU reset. That's not a brilliant sign.
