Hi,

Would appreciate help on this. I have a Powerbook G4 (15", 1.67GHz, OS Tiger) that of late goes to sleep when I am working on it.

Have gone through the net and have tried resetting PRAM, resetting PMU, discharged the battery and recharged it but to no avail.

Do I need to take the G4 to the service centre or is there an easy way out?

Please do tell.

Regards
 
MY PB G4 goes to sleep by it selfs, i have reset the VRAM and PRAM and still does it...Did you find a solution?
thank you

What does system.log (in Console) say when this happens? I can think of a few causes for this; either:
a. you have hot corners turned on, and are accidently putting the machine to sleep

b. you have some bad system thing - try repairing permissions/disks

c. your temperature sensor is going
 
no messages errors appears when it goes to sleep. The hot corners aren't enabled in the sys preferences....i did try many times to repair permissions without succes...my question is if i reinstall Tiger, is it going to resolve the problem maybe, is it a software issue?

thank you for the help
 
It could be a software or hardware issue. You can isolate that with a re-install, though that would be a inconvenient way to isolate it. You could also install OS X on a firewire drive and boot off that - then see if the problem persists.
