Q: Strange problem with new iBook G3 battery
Hi everyone!
I'm facing a strange problem with the new battery I've bought for my 12" iBook G3 800MHz (full specs PowerPC G3 800MHz CPU, 640MB SDRAM 133MHz, DVD-ROM, 20GB HDD, running OSX 10.4.11)..So I've got this laptop two months ago from a friend who wasn't using it anymore, and the original battery was almost dead: 141mAh of maximum charge was giving me about 6 minutes of work. I've recived the new battery yesterday (it was completely charge-less: the indicator lights weren't working), but it has this curious problem: when the iBook is off, it won't charge. I gave it a full charge with the laptop on, up to 100% (4414mAh), and was working fine. But this morning it started going crazy: osx gets bad charge readings, since the percentage jumps randomly from the correct value (and there stays about 2-3 minutes) to 3-4% or 100%. The battery itself is working: only readings are really bad. And there's still the odd "I'm not charging while iBook's off" problem..I'm currently trying to calibrate the battery: could that be the problem? I've already made PRAM, NVRAM and PMU resets..ideas? Thanks
iBook, Mac OS X (10.4.11)
