re: Help, Powerbook 12" stalling when trying to awake???

Message #1 - Posted 2006/10/23 - mammothta

Hi,

I have a Powerbook 12". so far there has been no problems what-so-ever. however, lately, i noticed that this powerbook infrequently has trouble "waking-up" after many hours of use during the day. The scenario is like this: the unit is on and I often close the LCD and it goes into sleep mode (fine)... after trying to open the LCD again, usually the computer wakes up... however a few times already, the computer LCD screen blacks out and does not come on and seems like the machine is on still, but can't see anything. I have to therefore take the battery out and unplug the a/c so i can do a hard reset. I never had this problem before.

A) is there something wrong with my powerbook?
B) is the LCD going bad?
C) any other issues i need to worry about?

please advise. thanks in advance!

D) the inverter is going bad.(if you still see something on the dark screen)

You should try with a clean installation first.
If it is a hardware related problem I would expect to see the same problems at startup too. Did it ever remained dark at startup?
