kpreid | Sleep problem update

I wrote in a comment previously:

No, it's a PowerBook G4 12", latest revision (scrolling trackpad).

It goes to sleep normally. On wakeup the light goes out and the drives make the usual noises, but the screen remains off (not blank, and not backlight-off-but-showing-an-image). The one time I tried network access, SSH just hung and ping reported, IIRC, “Host is down”.

It didn’t do this when I first got it, but I didn’t put it to sleep for a while after that so I didn’t notice exactly when it started doing this.

I had an unrelated crash today, and I decided to try something while I had the opportunity.

I turned it off, waited five minutes, unplugged everything, waited five minutes, removed the battery, waited five minutes, put the battery back in, waited five minutes, plugged it in, waited five minutes, and then turned it on again. Now it works.

Ah, modern technology.

Update’s update: Apparently if I do anything but click Sleep at the login screen, it again won’t wake up. Ngh.
