Better energy savings -problem with my iBook

[Jiddick ExRex]

Weird. When I run solely off battery with energy savings on, it shuts down screen brightness to 0. First time is when battery is half charged, next when the battery is almost down to none (with 10-20 minutes to spare). The only way for me to fix it is to shut down the lid, let it go to sleep and wake it again.

I HAVE tried resetting the PMU (command, apple, shift, on-button) and it still does it? Do you know of a way to fix this?

Just to clear this up, are you saying the screen turns itself off at ~50% and ~0% charge and it won't respond to the screen brightness key F2?

 

[Jiddick ExRex]

Yes. That's excactly what I tried to say (I may have failed miserably)

Okay, well I'd personally try re-seating the battery and then resetting the PRAM. Not sure how successful it'll be, but it's worth a try.

Also, try trashing a file named com.apple.PowerManagement.plist and restarting.

I will give it a try, and then get back to you. Thx.

Yep, it didn't work...

It still does it, this time during normal settings with an external display. The external display didn't go black though.
