So, I have an iBook G4, 1.4 GHz Powerbook, 512 MB of memory. It's 2 years old.
Lately it has been shutting off at random times with absolutely no warning or normal shut-down procedures. It just turns off like a switch. When I start it back up it has reset it's date/time to March, 14, 1969.
-.-
It usually happens when I am running a larger program like photoshop CS2, though not always. To make it clear-it's not a battery issue, because it has happened when it has been plugged in and I have no reason to believe that the charger is screwed up.
Let me know if you know what it going on and what I should do. It's happening quite frequently and I run a risk of losing things I am working on.
69 is an odd date yea, normally they reset to 1974. what you can try to do is boot up with command-option-p-r held down on the keyboard and keep them held down until you hear the boot tone again. thatll zap the parameter memory and might sort the issue out, but theres a chance that the little battery on the logic board has run out of life (odd for such a relatively young computer), in which case the date will keep resetting.
the reason for the shutdowns is quite difficult to diagnose but some things to try are: pull out all the ram, blow some air on the sticks and the slots, and put it back in again. try running it with the battery out and the laptop plugged in, because the battery could be somehow causing the power management to flip out. try sticking in the system disc (or any osx disc) and booting off that by holding c as the comp starts up. if that one stops it shutting down then its a software issue and you should reinstall the operating system, but make sure you test it for a long time first cos its quite an annoying step to take.
if none of that stops it then stick in the system disc and hold the d key at startup and it should dump you into apple hardware test which you should run about ten times to see if any errors are reported. if holding d doesnt take you into the hardware test then you probably have a separate disc for it somewhere.

The reason it is 1969 is because Unix-based operating systems count, in seconds, the time since January 1 1970, 0:00:00 GMT (Dec 31 1969, 4:00PM pacific time). So when there is no time available, it will think that zero seconds have passed since that time, hence the odd date.
"As a result your clock will reset itself to 1969, 1956, or 1904."
My Pismo was 1904, but Most of my G4s were 69. I'm still having difficulty finding what and why. 1956 was Steve Job's birthday. Someone somewhere has to know.
