iMac crashing when put to sleep or awaken

Message #1 - Posted 2001/06/10 - Paul Fuchs

I have a 233 rev B iMac with 288 MB ram. I moved from 8.6 to 9.0.4 a few months ago, and then to 9.1 a few weeks ago. At this point, the major problem to the stability of the system involves sleeping. I had the energy saver cp turned on for automatic sleep after 30 minutes of inactivity. About 25% of the time the machine would not wake up, and I would need a hard restart. The longer the machine was sleeping, the more probable it wouldn't wake up. However, I don't think I ever had this problem when I put the machine to sleep manually through the special menu. At this point, I have the energy saver cp turned off, but I would really like to use it for automatic sleep.

My second sleep problem is that maybe 25% of the time, when I attempt to put the machine to sleep manually, the finder crashes. The mouse pointer still works, but everything else is inoperative. This also requires a hard restart.

I remember when OS 9 first came out there was a lot of discussion about sleep related problems on this group. Unfortunately, I didn't pay much attention, as I was determined to stick with 8.6 for quite a while.

Does anyone have a clue what's causing this and how to remedy it? It's almost like running Windoze ;-(

PS

My most problematic software is MacSoup 2.4.6 and Real Player v .5 and v.8. I run v.5 when I can as it seems more stable. These two apps seem incompatible, and I don't have them running at the same time.

I own Diskwarrior and TTP 3.0.1 and neither fixes the problem.

My energy saver cp is v. 3.0.2

The idle time Energy Saver settings are stored in your Mac's hardware and therefore removing the Energy Saver control panel should not disable this functionality.

You may find it helpful to install DssW Sleep Monitor. It is a free extension we released that produces a log file of power management events, such as wake up, sleep, start up, shut down. The log file also includes changes in any energy related settings that have changed. An extract is appended below.

Look out for Sleep revoked and deny events. These are caused by extensions/applications refusing a sleep request.

You can download a free copy from <http://www.dssw.co.uk/>.
