My iMac G5 won't wake from sleep with a wired keyboard or wired mouse

My iMac just started having a problem in sleep mode. Whether I put it to sleep or it goes to sleep on its own, it is shutting down completely and I must use the power button to get it up and running again. It has just started this for the last few days....maybe a week now. I am not using the bluetooth so its not the lack of communication between keyboard and/or mouse and computer. Don't really know what is going on but am getting tired of restarting throughout the day. I usually leave my computer on all day and manually put to sleep at night. I was hitting the space bar to wake and now I must restart with the power button. Any suggestions or solutions???

Have you reset the SMU and the PRAM? Try deleting the System Preferences .plist in User>Library>Preferences>com.apple.systempreferences.plist. Please post back with results,

IMac G3 won't wake from sleep?

I have a iMac G3 500Mhz computer with 128Mb of ram and just recently added another 512Mb chip. My question is that my mac won't wake from a sleep, and when it is restarted it always goes to the disk aid whether the computer was shut down properly or not and that takes for ever. It never use to take so long. I also noticed that in some website, yahoo for instence it hangs while I try to receive my email. I have tryed to zap the pram I reconfigured my desktop I've fist aided it and it say's everythings fine. What could my problem be? I live in newfoundland and no one here know anything about macs. I had a guy over to try to fix an earlier problem but I think he made it worse. He uploaded a version of osx and I had os 9.1 but I couldn't retrieve any of my old files because it wouldn't classic share so I had to redo os 9.1 over everything. Could I have messed something up in the process to make my computer do all these funny things?

You should be able to get it from electronics stores (and probably from mega-computer stores) or from Radio Shack type stores. If they are charging more than $10, an online order may be cheaper even if there is a shipping charge. I have bought these batteries here with good results.

I don't have your type of iMac CRT, but it should be an easy replacement. You can find instructions online, or just ask here...
This article below lists things that are stored in PRAM, but people here have describe many different issues that where related to a weak or dead PRAM battery. Many had to do with startup issues.

IMac 6 won't wake from sleep

This is a 2nd hand question, as the computer does not belong to me, but I'm trying to assist a friend.
The iMac will not wake from sleep. If the hard drive is set to never sleep, the system will come out of sleep. But if the hard drive spins down and the system goes into standby mode, it can't be awakened. Not by a short press of the power button, movement of the mouse, or click of the keyboard (wired or wireless).
The iMac was taken to an Apple store for diagnosis. They used a 3rd party software tool (not the default OSX diagnostics) that showed no hardware issues per se, but it was noted that when putting the iMac to sleep and attempting to awaken it, the processor never gets a signal to do so. They surmised that it may be a power supply issue or something to do with a component on the motherboard. They re-installed the OSX completely fresh to rule out software as an issue. But the next day, the owner found that the same problem persisted.
First, I'm curious to know if anyone has ever reported this problem with the iMac 6 and if there's a known culprit. And naturally, if that culprit is easily fixed or if the motherboard would have to be replaced.
Second, since the problem does not happen with the hard drive staying "awake", would this problem be averted by installing an SSD?

Hello, what 3rd party Apps might be installed?
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Leopard 10.5.6 imac 24" won't wake from sleep

Hi - Recently my mac has stopped waking from sleep. This happens about 50% of the time and neither the keyboard or mouse will wake the machine... the only resolution is to hold the power button.
Is there anywhere I can check to see what's causing this or a quick resolution \ additional troubleshooting I can perform?

Oh yes, trouble.
I too have an iMac 24", and the problem I've seen is that it doesn't even get to sleep fully. It will shut down the screen, but I still hear a faint fan noise from inside. That's when I know it wont wake again and will need a press-and-hold power down.
But it's not always broken. I'm on the track to find a cause, and *every time it fails it's if I've previously run VLC.*
I'm inclined to think VLC is not the problem, just the catalyst for the bug in 10.5.6.
Can any one corroborate this pattern?
(ps I've not tried Caroline's suggestions)

MBP won't wake from sleep with lid down

This has been happening ever since the installation of 10.8.2. i can put my MBP to sleep and leave the lid open, and it will wake without issue. but, if i put it to sleep and then close the lid, the next morning, it will not wake.
when i open the lid, the white "sleep" light goes away, but the display is still black. my only recourse is to force shut down and restart.
has anyone else experienced this?

Does this problem still exist in the newer versions of the OWC firmware?
While my SSD is not an OWC, I've been having this issue with my OCZ Vertex 2, also based on the Sandforce chip.
OCZ's most recent firmware (1.32) has fixed the issues related to hibernation (i.e. "safe-sleep") but the drive still has issues waking from timed inactivity sleep.
I wrote about it on their support forums in this thread:
http://www.ocztechnologyforum.com/forum/showthread.php?86538-Hibernation-works-b ut-wake-from-auto-timer-sleep-problem-still-present-in-1.32
One of their support staff (who has been very helpful in ironing out the hibernation problems) replied with:
"I can tell you this new FW build has been fully validated by Apple at their labs, it may be possible your machine while fine with hdd may have an issue with newer ssd...or the line of macbooks with this issue are looking now for an efi update.
I will pass this back to SF but I suggest you also contact Apple and ask if a new EFI update is coming."
While my machine doesn't often sleep due to inactivity, it does happen. I am not a fan of the suggestion to set inactivity sleep to never. While this is a way around the problem, I don't consider it a solution—I would like the security of knowing that if I ever walked away from my machine on battery power for a few hours, I would be able to return to something that hasn't completely drained itself of battery.

IMac won't wake from sleep since Lion!

Since installing Lion my iMac (intel core 2Duo) won't wake from sleep properly using my wireless keyboard, trackpad or magic mouse! I haven't changed any settings and I have to hold down the power button to force shut down and then restart! Any help?? x

Hi all
Finally went to the Genius Bar to ask the question as nothing has worked. They said I needed to reset my PRAM. I did it (Following these instructions... http://support.apple.com/kb/ht1379 ) and it worked.
So relieved....it was really annoying me.
Hope this helps others with the same issue.
Thanks

IMac won't boot if Firewire device is turned on/won't wake from sleep

I am sometimes having an issue where my iMac won't wake from sleep; after I restart the iMac wont reboot (grey screen) until I power off the LaCie 300GB Firewire drive. I just bought this iMac a couple of weeks ago but the Lacie was on a PPC G5 Tower before and always was OK. I have no other Firewire devices to test the port with so my resources are limited. Anyone heard of anything like this ?
Message was edited by: appleboyperry

I noticed there is a firmware updater for LaCie drives. I don't know if it applies to your product, but here it is
http://www.lacie.com/support/drivers/driver.htm?id=10053
Please note what it says about backing up data on the drive before applying, just in case.

IMac 17inch G5 won't wake from sleep

Hi, my iMac G5 1.8ghz won't wake from sleep. It had been running poorly for a couple of weeks so I've re-installed Leopard however the underlining problem has not been fixed, which leads me to think it may be hardware? If i leave the iMac alone it enters into sleep mode successfully however nothing will wake it. I've tapped every key on the keyboard and nothing works. I then have to hold the power button in and re-start it. The only alternative I've found so far is to turn off sleep in system preferences.
Thanks for any help

Won't Wake From Sleep

I held off from posting this until I'd scoured the boards looking for ideas, but I'm totally out.
Every since I updated to 10.4.8, my MacBook Pro won't wake from sleep. I've tried resetting the SMU and PRAM, enabled and disabled bluetooth device wake from sleep, and installed the latest EFI Firmware update that was just released. I've now narrowed it down to the 10.4.8 and a change in how it handles Expresscards. If I have my NitroAV FW 800 card plugged in during a session, it seems to prevent the MacBook from going to sleep properly. According to various Console messages, the PCI device prevents the computer from going to sleep, and /or places the computer into System Doze instead, from which it won't wake. The sleep light stays fixed and steady, only disappearing if I press the power button (it only reacts to the power button). From there the screen remains dark and all plugged in device fail to respond. I can hear the drive spin back up.
It reacts the same whether or not I eject the card before putting the computer to sleep. This behavior was not present before installing 10.4.8 and having fallen back on a back up of my 10.4.7 install, can say it's not present in the older OS version. I was hoping last night's EFI firmware update would deal with this, but after having installed it and 10.4.8 anew, I'm having the same old results.
If anyone has any new ideas or can direct me toward how I can make sure the folks at Apple see this, I'd greatly appreciate it.
MacBook Pro 2.16 Ghz Core Duo Mac OS X (10.4.8) 2 GB Ram, 7200 rpm HD, NitroAV ExpressCard FW 800

Macbook Pro with Leopard Won't Wake from Sleep

I'm intermittently, but with increased frequency finding my MBP won't wake from sleep. A copy of my log is below. I've snipped out where the log repeats. A common message is the "unknown SIGSEGV code 0". Any ideas what the issue is? How can I go about diagnosing?

Hi David,
- Have you tried any troubleshooting steps?
You may try the following steps:
1. Reset SMC as per the following article http://support.apple.com/kb/HT3964?viewlocale=en_US. If this does not resolve the issue then go to step 2.
2. Navigate to Macintosh HD/Library/Preferences/System Configuration and remove a file called powermanagement.plist (drag it to trash, might prompt for a password). Restart the mac thereafter. If this does not resolve the issue, boot to safe mode as per http://support.apple.com/kb/ht1455 and check the issue there. If it works there, you will have to remove the following files to check Macintosh HD/Library/StartupItems, HD/Library/Caches and then restart the mac.
Let me know if this works.

OSX 8.2 new Retina Macbook Pro won't wake from sleep.

Since upgrade to OSX 8.2 new Retina Macbook Pro won't wake from sleep. Tablet lights are on in morning and fans running like crazy, but it requires hard quit and start. Tried with no apps running, no change. It was fine before this last update. Wasn't the recent firmware update supposed to fix this issue? It seems to have started one for me.

I have the exact same problem with my Macbook Pro OS 10.8.4. What happens is: I work on the train, press cmd/alt + eject to put to sleep..pop it in my bag...get home or office... open the lid...and nothing! Battery indicator shows I have plenty of juice but it will not wake up no matter what key I press.
The only difference between use on the train and home/office is the plugging in of peripherals and mains power. It happens sparadicially, perhaps once or twice a week and I always send a 'panic report', so somewhere there will be approx 20 reports of this fault at Apple.

Since upgrading to version 10.8.2 my MacBook Pro won't wake from sleep is her anyway I can fix this?

> during the entirety of this process the cursor was a "busy" pinwheel/beach ball/whathaveyou for a solid 30 minutes before I turned the computer off with the power button.
All that cursor means is that it is busy trying to do something. You can see if force quitting solves the problem with a simple force quit using command-option-escape. If you are having issues with iCal quitting, sometimes it doesn't always know whether or not it is properly communicating with a particular calendar. This can be a Mobileme issue, or even a phone synchronization issue, or a network issue reaching a shared calendar. Shutting down a machine directly from a cursor is the last step one should try, only after all others have failed. If you have done this in the past, lurking corruption can get worse each time with the directory, and upgrading the system will only enhance any corruption already present. When you restart your Mac, does everything appear to be normal?

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.

Macbook won't wake from sleep

My macbook won't wake from sleep. I have to power down and restart. I have also noticed that when it is asleep, the sleep indicator light doesn't pulse, it just stays on steady. Could this be a bug in mavericks? I have a Seagate external hard drive that I use for my Time Machine backups that it always connected. But ejecting it before the macbook goes to sleep doesn't seem to solve the problem.
Any advice would be appreciated.

You can access System Logs and other information on the computer's status in Console utility; where there are endless lists of all the processes ongoing in the Mac OS X. There are specific log-out and other automatic items the system will post to such logs.
•OS X: When your Mac doesn't sleep or wake
http://support.apple.com/kb/TS5357
Such articles are helpful in so much as they also have additional links.
Perhaps the computer is not going to sleep. The system logs can tell this.
Regarding power management, sleep, and other activities, have you read through the article about the System Management Controller to see if any of the items listed there can help? They'd take time to go through the list. And the end item is a reset of the SMC, after reading through and troubleshooting from the list.
•Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964
A good idea is to make a backup of your content in the computer, to an external hard disk drive, so when or if you end up totally erasing the hard disk drive (to include secure erase one-pass overwrite) and reformat GUID, that an all new system could be installed on there, in part of a larger troubleshooting effort.
Actually, if you have an externally enclosed hard disk drive with its own power supply, (not port power) and then use Carbon Copy Cloner (see Bombich software) to make a bootable clone of your entire system to a large enough external drive capable of booting in OS X, then you could get to the bottom of this issue. While keeping a boot copy of what you already have, because you can run the computer from an external clone.
•Mac Backup - Carbon Copy Cloner:
http://bombich.com/
A good source for external drives that can handle clones
is macsales; or a place to look to compare real details.
The problem could be based in software, or in hardware. Troubleshooting against either possibility is how to resolve this problem. Some models of earlier MacBook & other intel-based Macs do not really like Mavericks; or perhaps like it less than an earlier system it may have shipped with. The earliest like Snow Leopard best.
Anyway, there is a solution but it won't be a one-liner.
I've done some 40 hour days, troubleshooting issues.
Worst problem for me was buying one w/Applecare.
Good luck & happy computing!

MBA won't wake from sleep while connected to VGA Display

Since a few days I'm using a VGA Display connected through the official Apple Mini Displayport - VGA Adapter. However, when I put my MacBook Air to sleep and then close the lid (otherwise closing the lid will just continue on the display). Keeping the monitor attached, it won't wake from sleep anymore. Disconnecting the adapter at that moment won't make any difference. What troubleshooting steps can I make?

I usually...
Take out the charger
take out the battery pack
reinsert the battery pack
Then click the power switch
(if you have low battery I'm sure it would be a good idea to plug in the adapter again
