IMac occasionally fails to wake from sleep mode

This is a transient problem. Happens every 2-3 days that computer fails to wake up from sleep mode. Space bar doesn't do anything and I finally have to unplug it and reboot. I have a late 2008 iMac and am running Lion. It has started doing this after I installed Lion but doesn't seem to be related.

It's tough to troubleshoot intermittent problems. You can try by restarting in Safe Mode, this will clear some caches. It's possible one or more is corrupt.

Macbook occasionally fails to wake from sleep

i have a new macbook (purchsed in july) which occasionally (every 1-2 weeks) fails to wake from sleep. it either hangs on the blue screen which first comes up when you switch it on, or on the black screen which normally follows shortly afterwards.
i regularly use it "closed", i.e., with an external screen and keyboard, but the problem seems also to happen occasionally when i switch it on without these peripherals.
any ideas?
i've also had dvd player crash once. it was in full screen mode, and i couldn't switch to any other applications or force quit dvd player, so again i had to cut power.
Macbook Mac OS X (10.4.8)

Having similar issues...not that it happens everyday ...it's very infrequent..but yeah im in the same boat..
As far as the computer being hot...
Go to :
System Preference--->Energy Savings
From there you should have the boxed check both on Battery power and AC Cord to put the Hard drive to sleep when possible..
Once i did this it never happened again(the closing of the lid and still running)
as far as the other issue??Help.!!Anyone?

Etch A Sketch Problem - failure to wake from sleep mode

My iMac fails to recover from sleep mode. I have only noticed the problem when it has been left in sleep mode overnight. When I try to wake it, the last screen viewed appears. The mouse moves the cursor, but a trail of dark grey is made as you move the cursor. It operates much like an Etch A Sketch. When the power button is pressed, the log-in screen appears. After logging in, the iMac seems to operate properly. This just started last week. I haven't loaded any new programs. Has anyone else experienced this problem? What is the cause and a possible solution?

Here's the article, review the bottom of the article.

It's most often caused by automatic logoff

IMac with waking up randomly from sleep mode

Hello everybody!
Since I installed Snow Leopard (all updates done) my iMac is randomly waking up from sleep mode without any reason that I know of. Some days everything is fine, next day it wakes up when I am at work and retrieves mails (thats how I see it is awake).
Also I set it up to shut down after 1h idle time- this does not work as well.
Any ideas how to track the problem?

Just happened again.

Compter won't wake from sleep mode

My Pavilion 17 notebook computer, purchased in Oct. '13, won't wake from sleep mode; I must shut down and reboot each time. I know this is not due to Windows 8, as I have another Win 8 computer that works normally.

I've done some more experimentation and found a workaround. I had Sleep and the Screensaver both set to Never, and by activating the Screensaver the wake up issue has gone away. This doesn't change the fact that there is an issue with my ATV sleeping when it shouldn't and failing to wake up, but having the screensaver active stops it sleeping in the first place I guess.
It's slightly annoying because I like to have music playing with the description and album art running, and this disappears when the screensaver comes on, but it is better than unplugging the thing every time I use it. Hopefully this will be fixed in the next update, because it only appeared in the last one.

Computer won't start & fails to wake from sleep

First post -- I have a 2009 HP Pavilion Elite w/Windows7. Good box & OS, never a problem until now. Started about a month ago w/the box not waking up from "sleep" -- no response (power light turned from amber to blue as usual but nothing else happens). Had to turn it off, but then won't come back on! After 10-15 minutes of repeated power-on button presses, it starts back up. Removing/reinserting the power cord during trys doesn't help. Occasionally it starts right up from sleep, but usually has this problem. Windows7 is up-to-date and no viruses or malware detected. HP or Microsoft diagnostics show no issues.
I opened the box to clean out dust -- also took off the CPU heatsink (really dusty) & cleaned it too. Fans rotate easily & aren't an issue.
So now I have "sleep mode" turned off, but occasionly the box has to be turned off & afraid it won't come back on. I've seen some of the HP videos & will try shorting the two start-up pegs on the MBoard, but the power-switch was hardly ever used & I seriously doubt that's the problem -- it wouldn't have anything to do w/the sleep-wakeup problem. Any suggestions?

Helix 20CG won't wake from sleep mode

Hi
After doing all updates (windows/lenovo) and ensuring latest lenovo power managers are installed, my Helix 20CG will still not wake from sleep mode. This problem has been persistant since the second day I had the computer.
If the Helix is in sleep mode for more than 2 hours and you press the power button, the screen will not turn on. However if the tablet is docked on the ultrabook keyboard the green light on the Fn key will briefly flicker. Also if you press the power button and then immediately hit the windows button on the bottom of the tablet it will vibrate a bit, but in both cases the screen does not turn on.
After continuously hitting the power button for ~5-10 minutes the screen will eventually turn on.
Has anyone else experienced this problem?
Thanks,
Brandon

For the past week, I've been using the Helix and just shutting it down every time I walk away from it. This morning I put it in sleep mode walked away for an hour or so and when I went to wake it up, by pressing the power button, the green light on the Fn key flashed but it would not wake up. I held the power button down for 4 seconds to do a hard reboot. I checked the system log, and when the computer was "asleep" the following warnings were recorded:

IPhone 1.1.4 will not wake from sleep mode

Hi all,
I have an iPhone with 1.1.4 firmware. The problem that I have is that the phone will not wake from sleep mode by pressing the "home" button. I have to press both the "home" and "sleep/power" buttons and hold them for 6 seconds for the phone to restart. I did restore the phone twice - did not solve the problem. Then, one day, I left it charging for about 3 days and when I came back it started working fine. Not for long though( After about a week of normal usage the wake up problem came back. I don't know what to do. I don't think it's the software problem, since I did complete restoration 2 times.
If the phone is connected to a charger or computer - it wakes up fine.
Thanks, Gene K
Message was edited by: rimini

rimini,
When you've restored the iPhone, have you tried setting it up as a new phone? This would truly eliminate software as a possibility.
If setting it up as a new phone doesn't correct the issue, it's probably time for service: apple.com/support/iphone/service/faq/
Hope this helps,

T410 fails to wake from sleep with 2nd Hard drive installed?

Ever since I've installed a second hard drive in my T410, a Hitachi 250GB drive, my machine fails to wake from sleep (sometimes)... Then I have to do a hard reset.
I had the same problem without the 2nd drive when I tried to use the HD Password in the BIOS and found out that it was something to do with the Crucial M4 drive I'm using. But this same problem is now happening ever since using the 2nd drive slot.
Any ideas? I really like the extra storage space and don't want to remove it based on this problem.

Solved!

Well it seems the problem was caused by the firmware version for the SSD I've installed.
The problem was resolved by updating the Crucial M4 SSD with the latest firmware.....
......and It solved the HD1 password issue too.

PowerBook won't wake from sleep mode

My PowerBook G4 won't wake from sleep mode. I open the lid and nothing happens. I hold down the power button and nothing happens. I resetted the PMU and it will wake up and I am able to login and then it goes back to sleep mode. What should I do please help? And if my computer is dead, is there any way to retrieve my information saved on the hard drive?

this would happen to me when my battery was dead. you test the battery life? (little button on bottom near battery)
I'd make sure it was plugged in and let it charge for 10 minutes or so. then try restarting it if it doesnt wake up by itself.

Battery wakes from sleep mode

I have a user who's laptop wakes from sleep mode while the laptop is closed. We changed the battery, checked all settings for sleep mode (wake on LAN, etc) and it still wakes up while the lid is closed. Also, the laptop gets really hot on the left-hand side by the fans, below the screen.
Any other suggestions of what it could be? I'm not sure where else to go.
Thanks!
Solved!

Hi again, itjedi
I did some research and found that there are some driver updates available for the machine that may be of some assistance. I would definitely make sure the BIOS gets updated, but the others may help as well. All of them can be found here, and the results can be filtered by OS and device type if you'd like.
Best of luck. Let me know how it goes

Powerbook Ti will occasionally not wake from sleep mode

When I put my powerbook in sleep mode, either it will wake, or it will wake but the screen will be blank. The HD will have turned on, the pulsating light will have turned off, and you can hear the fan running. I'll then have to force shutdown and restart.
So far I have tried:
1. sleeping via the powerbutton and choosing sleep to see if that changes anything
2. to plug in a peripheral via USB
3. to wait it out to see if the screen appears
4. to reset the PMU underneath the keyboard
5. to check to see if my ram was bad
6. to repair disk permissions
7. to repair file systems via fsck -f in terminal
Nothing has worked. Please help anyone. Thanks

ckoeshall: The note you quoted from that article concerns desktop Macs, most or all of which use non-rechargeable PRAM batteries. The internal backup battery in your Tibook is rechargeable, and is responsible for maintaining your time and date settings when both the main battery and the AC adapter are disconnected. It will only last a few minutes under those circumstances, though (it lasts long enough to let you change the main battery or get connected to AC power when your main battery runs down). You haven't mentioned that your time and date settings don't hold (but of course they're lost when you reset PRAM or the PMU), and I'm not aware that a depleted backup battery can cause the wake-from-sleep problem you're experiencing.
To recharge your backup battery just to eliminate it as a possible factor in your problem, remove the main battery and leave the PB connected to AC power for 4-5 hours. It takes much longer to charge the backup battery if the main battery is in place and in need of charging too, because the main battery evidently gets priority.
The fact that you have a third-party main battery probably has nothing at all to do with your problem. By now, I suspect that a large majority of Tibook users are operating with third-party batteries, since Apple no longer sells them.
