ok so I'm really happy with my new mac and all, but i have encountered a pretty serious glitch(?) here. whenever i put my g5 to sleep for too long, it will fail to wake up. I can hear all the normal noises coming from the machine, yet the screen (17 inch studio display) remains blank. any suggestions?

Have you tried pressing the power button on the display? I know this happens to my Dual 1ghz G4 MDD whenever it is asleep for extended periods of times. No amount of mouse movement or key pressing will awake this slumbering beast unless I press the power button on the display.

my PB does that sometimes. althought it's not as bad, occasionally it will sit at a black screen for a while after waking. i find this is even more so when using password upon waking from sleep.

it also depends on which button i press. i can't use the trackpad, but i can use the trackpad buttons and keyboard.

Re: sleeping glitch in panther (maybe)

Yes. I have this problem too. And I have the 17 inch studio display as well. However, I don't have a G5, I have a 1.25 dp G4. Pressing the power button on the monitor does nothing for me.

My work around is this:
You can get the display back by unplugging the monitor from the power source and then plugging it back in. Actually I unplug mine from the connection on the back of the monitor. This works for me.

Maybe it has something to do with the DVI Display Adapter. Maybe Apple would like for all of us to buy newer monitors.

I am having the identical problem with my new G5 Dual. The screen activates if the computer is asleep for only a short time, but after overnight it remains black. Switching off the computer did not help, unless the display was also unplugged and re-connected.
Now with Panther just installed the screen does not stay black but instead produces a pattern of coloured vertical lines. I sent it in for servicing today, so will keep you posted.

When this happens on my PB I just shut it again and reopen it again. It then runs just as normal. I had this happen twice since owning my PB for almost a yr now.

hi guys this may sound daft but here goes anyway. When my powermac and studio display go to sleep no amount of mouse moving will wake them. I discovered that simply clicking the mouse once brings them both back to life with out the need for unplugging. Worth a try, although you've most likely done it already.

Yep. 10.3.1. Although this morning my display came on just fine. Yesterday I had to do the work around. I'm not sure what the deal is. Sometimes it works and sometimes it doesn't.

No problems on my PowerBook or on a G4 MDD with a 17" Studio Display, both on 10.3.1. Although, I only sleep the display on the G4, not the whole machine...

Nope. Not today. Today I had to do the work around.

I've had this happen on my AL15 PB. What happens to me is that the machine has awakened but for some reason the screen brightness is turned all the way down. For a PB this is no problem, I just press the function key to brighten the screen it comes back to life.

This may be more problematic with a desktop. Try setting a function key to affect screen brightness. Then try the func key next time the machine fails to wake from sleep.

Whenever I put my G4 to sleep, it sleeps just fine. However when I wake it up, everything comes on as usualy, only my monitor settings/calibration are all gone, and I have to click 'Detect Display' again to get my settings back.

Really annoying it is. Im just going to not sleep the machine, and only sleep the monitor...im just kinda worried about my computer getting too hot or something, but Im just worrying lol.

Sleep is an "enery saver"...not a "heat reducer/computer pro-longer" lol - thats what I keep telling my self though, to feel better about it lol....

I had to do this with my iMac ( monitor sleep with no computer sleep ) becuase of problems when the iPod was attached. It seems that if the computer went to sleep and the iPod did not, then the iMac would hang after returning from sleep. Monitor sleep with no computer sleep solved this problem.

My display screen still does not activate after overnight computer sleep, despite a "faultless diagnostic check" (according to the service technician). It sometimes takes several frustrating and time-consuming attempts. I would love to know what percentage of G5 owners have this problem. The Apple forum has numerous references to this problem too. I hope Apple reads these posts and is researching the issue!
Any suggestions of what to do to end this glitch?

Sometimes I have the problem of my computer (17" iMac) NOT going to sleep. I'd rather put it to sleep than shut it down but I don't want it running all night.

I wish the login screen had a "sleep" option.

Sleep problem with USB mouse

I'm running 10.3.1 on a G3 800 iBook. I've noticed that it can be awakened from sleep even with the lid closed by moving an attached USB mouse. I don't think that this was the case in Jaguar but it does lead me to believe that the iBook can run with the lid closed (which as I understand it isn't Apple-approved operation). Anyway, this was an annoying problem since my iBook would sleep again when I opened the lid. Workaround? Unplug the mouse before closing the lid.

Just thought I'd share.

As all the ibooks are based on PB designs and these machines have been able to be awoken by usb mice and keyboards I suppose it is only logical this should continue. I recently discovered that it's not only mice that can awake macs with my PB asleep lid shut I plugged in my usb printer and it started up. Anyone know of any other unusual usb items that awake a sleeping mac? I assume that such is the nature of usb (maybe even FW) any such device will work.

hi there, I have a similar problem with my G4 powerbook. I always use a USB mouse (i hate trackpads) and I turned off the trackpad (ignore trackpad when mouse present - I think) in the mouse and keyboard settings.

Power settings set to automatic. The PB goes to sleep, and I notice that my optical mouse lights off. I wake up the PB by hitting the space bar, but my mouse does not come back to life.

The problem is that since I have the trackpad off, I have no way of moving the cursor. I've tried to disconnect and reconnect my mouse, but the machine does not even "see" it.

This seems to happen in both Jaguar and Panther. Any suggestions? Should I just keep the machine from going to sleep?

even if the light on the mouse goes out if you move it or click the button it should still wake the mac as the device should still be detected. If you turn on full keyboard access in the universal access panel in sys prefs you will be able to have control even if you can't use the cursor. What happens if you unplug the mouse then plug it back in? The mac should detect it again (soz if you've answered that, short memory span!). What happens if you put the PB to sleep by closing the lid then awake it? Does it make any difference?
