It also appears that, in some cases, all external devices must be disconnected before putting the machine to sleep. * The machine does not "Wake for network administrator access"ĭo not connect, disconnect external devices during sleep Avoiding disconnecting or connecting external devices - USB, FireWire, etc. * The CD works normally and will accept media, but the system does not react appropriately. * The afflicted machine does not react to a network ping.
#MAC OS TIMER FOR SLEEP MAC OS X#
These fixes deal specifically with the two most common wake-from-sleep issues affecting Mac OS X systems - a completely blank screen with the system unresponsive where a forced restart is usually the only option and a kernel panic where a restart is also required.īoth manifestations of these issues also exhibit the following symptoms:
Tutorial: Dealing with Wake-from-sleep issues I've never had the problem happen twice in a row. If that doesn't start in a second or two, I know it's not really going to sleep, and I try to snap it back awake and start over. I normally keep my DVD±RW off when not in use.įor now, I always wait to see my Mac mini's power LED start its sleep pulse before I leave the room. It seems to me like it has something to do with my external devices (DVD±RW and/or game pad). Unplugging my USB game pad from my keyboard (or pluggin it back in if it's not in to begin with).
Hitting command-control-power on my third-party keyboard (which normally forces a restart).ģc. Hitting the power button on my mini again.ģb. I found FOUR ways that each sometimes work. It IS possible to wake it up when this happens just not through normal means. It's never happened when I select "Sleep" from the Apple menu (although I haven't done this enough to prove it conclusively what is your experience with this?).ģ. It only seems to happen when I put it to sleep by hitting the power button. This was the same time I had my logic board replaced (my original one couldn't handle the gig of RAM for some reason), and a week or so after I began using a LaCie FireWire DVD±RW (I wanted to back up my whole system before doing any upgrades, naturally).Ģ. The problem began shortly after I upgraded my memory from 256MB to 1GB. I haven't really nailed down a cause/solution, but here are a few facts of my situation, which I hope you'll find helpful:ġ.
The same thing happens to me with my Mac mini. I just spent $2000 on a machine and it appears messed up and Mac has no answer. Well that is where I am now, and it has not done it again, but I am still trying to find out what exactly is going on here. Then I restarted, trashed the energy saver prefs and ran a repair disk permissions task inside OSX. I restarted holding the command-option-o-f keys down, then prompted the computer to reset the v-ram, and two other things he suggested to reset that I cannot remember. Well I took one guy's advice that seemed to know what he was talking about. I looked on apple discussion boards and there is alot of this happening. Well it was fine again for about a week and then it happened agin yesterday, not once but twice. I called tech support but they had me turn the option off that puts the harddrive to sleep when possible and then turn off my screensaver. It would not respond at all to the keyboard or mouse so I had to shut it down by holding the power button on the front of the unit and then start it back up. I left for work and when I got home that evening after the computer had been asleep all day, it sounded like the computer was taking off from a runway. I set everything up and dowloaded all the updates for everything, and then about a week into using it the problem started. I just bought a new dual 2.0 ghz power mac G5 about 2 weeks ago.
