Clamshell not retaining PRAM Settings

Hey,

I've been having some problems with my clamshell lately. Basically, it's not retaining the PRAM settings whenever I restart. I keep having to manually enter all the settings after everytime I restart (not often, but still, I have to do it ;)). I am shipping the iBook to my cousin in AZ today afternoon, so I wanna get a solution at least for this before I ship it. Anyone have any ideas what this is?

BTW.I repaired permissions 'bout 3 weeks ago. I am running 10.3.9

No PRAM

Umm...actually, the clamshells don't have PRAM batts., they rely on the (main) battery power instead. My battery is 'bout 3 mos old and holds about a 3 hour charge, so I don't think thats the problem.

actually

from the tech records, it has a small capacitor that stays charged when the battery is removed. It sounds like the capacitor is going out. you might want to look for the capacitor and attempt to replace it

reset the power manager

IIRC, that's the cure for your issue. It's that tiny button behind the power button at the back of the palmrest.

With the 'Book off, press the reset button only once, wait 10 seconds or so, then start 'er up.

Also, you might want to do the ol' OF reset:
enter OF by holding cmd-opt-O-F keys at startup
at prompt, type "reset-nvram", hit return, type "reset-all", hit return again, it'll restart.

Whatever the problem, it has nothing to do with the permissions you repaired, it's a HW issue. I seriously doubt that the aformentioned capacitor is faulty BTW.
