The process said to reset the nvram (as explained in this article) then reboot to OS 9 and cycle the battery. I have long since 86'd OS 9 on my iBook so I had to pull out an old OS 9 boot cd. Well I decided to give it the ol' "Try # 378" - rebooting into OS 9. So I read the article again and noticed one persons comments about using OS 9 was the trick on REALLY stubborn machines. Tried the nvram rest, let it charge overnight - tried it. I finally decided the battery had just lived its life and was depleted, even though I have rarely even used the battery.Īfter reading the Macintouch article last week - I decided to give it one more go. I tried everything including the nvram techniques and nothing worked. It would charge fine, but when it got to about 80% it would drop instantly to 0%. I have an iBook 2001 (late, dual usb) that has been giving me problems for the last 3-4 months. Good luck with your (hopefully) repaired PB! I still don't know why a crap battery can do this at these settings, but for me this was definitely the cause and effect. It turned from full to empty within an hour - wich I never noticed before as I mostly used the Power supply. I now believe my battery is dead and has to be retired. I found out that it started working normally after I set the Energy Saver Settings to Highest Performance.īut setting the Energy Saver Prefs to Longest battery kills it instantly and leaves only a way out via forced restart. Tears, Screaming, nothing helped, I saw visions of ruined Logicboards etc.īut then. I reset and zapped whatever was possible but nothing worked. I had nearly the same thing with my iBook Dual USB, in my case it would freeze as soon as the powerplug was pulled, rendering it a non-portable laptop.
