SOS! computer sleeps at random... i think. help!


i'm using a powerbook g4, one of the early 2001 models, 667 mhz w/ 512 ram and 133 mhz system bus.

i have just installed mac osx 10.27 (jaguar) and i reinstalled the os because i was having an issue w/ the display turning off.

now it seems that everytime i hit the command key to the left of the space bar, the screen turns off. sometimes the computer merely sleeps, so that when i hit spacebar, it comes back on as if on steady state off mode.

however, sometimes it won't come back until i've either popped off the battery and reinserted it and then turned it on; or if i hold the power key til the system turns off, then turn it back on *mind you when the screen goes blank, it sounds as if the computer is off.

the screen goes black but it usually still has a ghost effect of everything i was last viewing... almost like a burn in but not possible as LCD's take atleast 15 to 30 seconds to burn. (or so i was trained when i used to sell LCD tv's.)

if anyone could help, i would greatly appreciate it.

i've looked up a few things on the net that tell me install firmware before the installation of 0SX 10.27 but i dont have another OS to give me that luxury; and my friend who believes himself to be somewhat of a computer buff, is stumped and doesn't believe it to be firmware related.

Have you ran any test on the computer? I say this because it sounds as if you are having some kind of hardware issue. Did you install any third party RAM? Do you have the essential maintenance disk/program DiskWarrior? I hope you haven't tried to use a discontinued product. Also, maybe you should take the Powerbook to your local Apple Specialist to see what they say about it.

P.S. - Please have some patience in forums. Not everybody keeps the same schedule as you.


ok. i have now tried diskwarrior, and it says that all harddisks are working properly and all that jazz. now i've got os 9.1 but the computer hasn't been able to boot from the disc. so i've done the stupid thing of drag the system folder from the disc volume to my harddisk and now the computer attempts to start from os 9, gives me the "question mark folder" and then starts up in osx.

also, sometimes i turn it on and it makes "boop boop boop" sound. and the ram i have in it is samsung pc133 256 dimms (2 of em) so i dno if that's incompatible... you be the judge. and as for the schedule thing, there have been 30 views on this topic and 3 replies, 2, now 3 of em which are mine.

i appreciate ppls respective schedules but i'm still wondering why nobody is helping me when they've been looking at the topic.

i'm trying to avoid the apple specialist thing because they charge an arm and a leg for the specific reason that very few ppl are entirely versed w/ mac's.
