Macbook Pro battery problem

Message #1 - Posted 2006/05/16 - Gavin Saxby

When I put my Macbook Pro in my bag this morning it was quite happily asleep. When I got to work and opened it, nothing. I pressed the power button, nothing. Once the PSU was plugged it it came on fine, the battery meter said the battery was charged (it had been plugged into the mains all night). I removed the PSU when MacOS had started, the machine instantly powered down. When I press the little button on the battery it lights up all the LEDs.

I tried the battery from a colleague's MBP in my MBP and it worked fine. My battery in his MBP failed to work.

It looks like my battery has suddenly and catastrophically failed :( Has anyone else seen this? Totally clutching at straws, is there any software related stuff I could try? I've already removed and reseated the battery several times, checked to make sure there's nothing odd about the contacts on the MBP or the battery and made the the battery was fitting properly.

Any assistance would be appreciated.

Cheers,

Gavin.

Try the Power Management Utility voodoo:

Shut the mac down cleanly
remove mains and battery power
Hold the power button for 5-10 seconds
Restart.

The gadgetry that tells the computer how much charge is in the battery can get corrupted, this clears it.

Is this an early (OK, *really* early) MBP? Apple recalled some because of battery problems sounding quite like yours:

Thanks, but sadly, it didn't help :(

I saw that earlier today, but my battery does still report a full charge on its LEDs when you push the button.

I'm trying to get the whole thing sent back to Apple anyway, the whining CPU noise is really starting to annoy me.

Cheers,

Gavin.

That whine is easy to cure using CHUD from the devtools. Unfortunately, it doesn't remember to turn the second cpu off if you sleep the machine.

Sod that. Send it back. Why should you have to dump some of the procesing power buy turning off a core. he paid for that core!

I think it'll always occur, unless a machine has better acoustics or they develop a modification to the power management that shuts off one processor unless it's needed.

Well, I have at least got the battery problem fixed. Apple sent me a new battery which arrived today and works just fine :)
