[DM-MUG] PowerBook G4 flickers

[John Kisner]

I have a PowerBook G4.  It's several years old (667 Mhz).  The screen 
flickers once in awhile, and I have more crashes than I would expect 
with Panther-- but maybe those are MS Word related (which I don't often 
use, but have recently to do some edits).  Today I had a new one: in 
the midst of browsing web (on Safari) the screen got darker and I got a 
message in many languages to hit the power button and restart.

Do I need to take this in for service?  Or does it still sound like 
"normal" problems?  Alas, my extended warranty expired earlier this 
year.
