PowerBook Battery Problem

Message #1 - Posted 2007/08/02 - Robert Peirce

I got a new MBP and gave my old Ti PB to my wife. I suddenly started to have battery problems, which apparently have nothing to do with Migration Assistant.

The original battery showed no charge and would not charge. The electric plug glowed amber all the time. I replaced the battery. With the new battery, the plug switches back and forth between green and amber. I seem to recall that it used to stay amber until the battery was charged.

I totally discharged the battery last night and plugged it in over night. It was only up to 20% this morning. I have reset the PMU a number of times but that doesn't seem to help. If I pull the plug, the battery icon goes red, as it should, so the system seems to be working a little bit but not all the way.

Any ideas?

Later that day . . .

The power cord plug is now constantly amber but the charge is stuck at 77%. It hasn't moved beyond 77% for a couple of hours. Remember, this is a new battery and the PowerBook used to charge correctly.

Have you reset the power manager and recalibrated the battery?

Have you talked to Apple?

Yes and yes. I also checked the PMU battery. It is okay. I talked to the vendor and it looks like this may be a bad battery. I plan to send it back.

Lot of that going around. And not just batteries made by Sony.
