Shutdown triggers sleep mode problem?
Authored by: evancm on Feb 11, '02 01:02:07PM

I have an iBook and tried this trick from Terminal last night, mainly because I was curious about what the display looks like in single user mode.

Logged in as root, I did a "shutdown now", and when I was done playing around in single-user mode, I "exit"ed the shell, and watched most of the bootup process occur.

I logged back in, viewed a couple of web pages, shut the lid to my iBook, and went to bed.

When I got up in the morning, the iBook would not wake (despite an AC connection and a full battery). I also noticed that the sleep light was not pulsating.

I haven't seen this happen before (I've had the iBook since November), so I can only assume that doing this "soft reboot" somehow screwed up the part of the system that handles the iBook's sleep mode.

Can you please confirm you discoverings by repeating the "shutdown now" trick on your iBook again?

I'm curious to know...

P.S. I hope it cannot cause any hardware damage...

I've done the shutdown now trick (Before it was posted) on my first gen iBook before with no harmful consequences. It may have been something unrelated that caused this problem.

Shutdown triggers sleep mode problem?
Authored by: Guiyon on Feb 13, '02 08:20:13AM

My iBook has started doing this within the last month or two (never used the shutdown command). Tries to go to sleep and crashes. Can't really get any support for it as it is very random. As for the shutdown command, i tested it on my Sawtooth G4 and it does drop me into Single-User mode. I have not noticed any problems with it.

Shutdown triggers sleep mode problem?-advice for those troubled with the sleep problem.
Authored by: Anonymous on Mar 02, '02 10:46:10PM

I had similar trouble with my TiBook (look under Apple Discussion Forums for "sleep of death". I called Apple support and a very helpful support person talked me through some weird-key combination rebootings and specific typed commands, etc. which fixed it.
He also suggested if it came back to clean up the perferences in:
/User/Username/Library/Preferences
by moving the folder to the Desktop, rebooting, and adding preferences one by one sort of like debugging extensions in Classic.
I'm guessing that one reason this problem is random is that some sort of preference from some application (3rd party?) doesn't get put in the right state during shutdown procedure, which gives the sleep problem. In the Apple forums, people with USB devices and desktops have also had this trouble.
Good luck.
