Computer goes to sleep won't wake up

I have given a laptop to an elderly parent so that she can surf. For several weeks now, at some point in the day the laptop goes black (to sleep?) and the slowly blinking white light bottom right glows steadily. Tapping the track pad or any key does not bring up the desktop. I have tried draining the battery and re-charging, changing System Preferences under Energy Saver for the display and computer to never sleep, cleaned up permissions with Disk Utility. That's about the extent of it, the computer shuts down every day I suspect at the same time but have no way to check.
This is a MacBook Pro 15" around4 years old? 2.53 GHz Intel Core i5 4GB Memory, 1067 Mhz DDR3. FWIW, the only non-native program is an application to run a signal antenna to connect her laptop wirelessly to my network. Generally the laptop is run connected to power, and I don't believe it makes any difference whether the laptop is left open or shut.
Appreciate any help you can give!

This isn't a fix, more a workaround I used when I had wake from sleep problems that lasted from some point in 10.6.x, through 10.7 and into 10.8 (got fixed for me in 10.8.2). It seems to be connected with Bluetooth failing to wake up properly:
System Preferences>Energy Saver and set 'computer sleep' to 'never'.

Went to sleep won't wake up

Just got a used 2004 ibook. Let if plugged in, came back fours later and sleep light was on. Couldn't turn the machine back on, though. Removed the power cord, no difference. Took the battery out and tried to restart, no soap. Sleep light is no longer on, iBook will not power up. AC Adapter was working fine, but now color charge indicator does not come on. Looked at the web pages, including the various restart procedures, so far nothing works. Am considering trying a different AC adapter, but am wondering what may have caused the shut down in the first place and/or if anyone has had a similar problem and how it was resolved.

These are some third party choices for an adapter, if you think that Apple's has fallen short of your expectations:
MCE Technologies
http://www.madsonline.com/index.html?
MacAlly adapter at Amazon.com
adapter at Other World Computing
Apple's is the only one with the glowing ring to indicate charging status, though, and can be found here:
http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore?productLearnMore=M89 43LL/A
I believe the one from Other World Computing is one of the sturdiest of the lot. The MacAlly adapter's cord is a bit flimsier than the one from Other World Computing, but both are working fine on our iBooks. We haven't tried the pricier ones.
Apple seems to be improving their adapter, too. The newer models seem to be a bit sturdier than earlier ones.

I changed the keyboard language from English to Vietnamese, then the computer went into sleep. I turn it on, it asks for the password, but the keyboard doesn't take vowels. what can I do?

You may want to wait for others to see this thread who might offer some other suggestions, but you could consider resetting the password. These instructions work for Lion (10.7.x) and Mountain Lion (10.8.x).

IMac 2011 screen unexpectedly goes black (to sleep), won't wake

I've been having an intermittent problem. I'm using an iMac (late 2011) with 10.7.3. I'm doing things on the computer or some process is going on when the screen instantly goes black (no dimming first). If a video was playing, I can still hear it playing, but pushing keys on the keyboard or mouse or pad does nothing to wake the screen. Sometimes pushing the power button a number of times will get the screen to come on, sometimes it won't. When the screen goes black, if an external drive was running and then stops, I can sometimes get the screen to come to live. Sometimes this black screen happens when I'm burning a DVD; when the DVD is finished, I can bring the screen to life. I thought one of my two external drives was bad, so I disconnected it. That seemed to help (though verifying the disk revealed no problems). But a few minutes ago, the screen instantly went black again; no dimming first. There have been times I thought this was associated with a new bit of software, but then it returns even after I delete the suspect software. Sometimes I have to use the power button to shut down the iMac then restart it. Once, I had to unplug and replug the iMac before I could get the computer to respond and the screen to return to life. I don't know if this is a hardware problem (internal or external), a software problem, or some combination...or something I haven't thought of, at all. Very annoying. Verified the internal drive, repaired permissions; no problems noted there.

Exactly the same issue here - same machine and OS. got so bad now that it blacks almost as soon as it comes on. Over the past few weeks I also experienced the flickering screen that others have complained about. The black screen only occured after installing latest update (7.3) - and I only installed this after earlier problems with the update reported by many users were sorted - but the flickering happened before so may be not relevant.
What's happening when you press the power button a couple of times is probably that you have 'use power button to put computer to sleep' selected in System Prefs. Henmce, 1 push puts it to sleep and 2nd wakes it up.
I have done all the usual checks plus power down, unplugged for 20 seconds and then restarted to reset the SMC (System Managemenmt Controller) but problem has recurred - normally after sleep.
Aplle did have a large batch of faulty LG screens apparently so maybe this is the poblem. Otherwise maybe graphics card issue,
Mine's off to a service centre tomorrow whilst it's still under warranty... will update when I get it back

My computer went to sleep and never woke up!

twin g4 867 MDD went to sleep at its scheduled time (2AM) The next day it would not wake from sleep as far as i could tell. Unplugged it, plugged it back in and i get startup tones but no video feed. HD's and fans are spinning. anyone have any ideas? Monitor burnout? graphics card? (i have a a nvidia gforce ti) im running tiger with all the updates, and an apple 20in cinema display. THANKS!!!

Hi,
If everything is spinning, it sounds like the graphic card is not working correctly. That particular video card has been known to do that. If you are familiar with your MDD, try taking the card out and re-seating it, then restart. Unplug the computer first.
Go here to see instructions in removing the video card in a MDD Mac:
http://docs.info.apple.com/article.html?artnum=26259
If that doesn't work, you'll have to locate a new/used video card that supports your ADC connector on your monitor and try that. Finding a loaner from a friend would be ideal.
Tell us what happens,
Regards,
Dave

Comp. went to "sleep", wouldn't wake up while in use (?!?)

Hey all, so yes I have one of the trouble-prone MDD G4's which has had TOO many problems to really go into all of them here (from the inadequate fan it came with that requires me to keep it in Nap mode all the time, to other freezes/Kernel panics that I assume may be related to the probably bad pirated OS I unknowingly installed in it). Although I suppose if I really wanted to spend the time and money on it, I could get it a bit more functional (and tolerable), but at this moment I've practically given up on it, and am just using it until I break down and buy a decent Mac laptop,
Still, I can't help but wonder when I notice a new problem, to see if I'm not the only one. And one I've noticed sporadically, and JUST dealt with, is this:
the computer seemingly "went to sleep" suddenly on its OWN, AS I was using it (just looking at a web page), and would NOT wake up, no matter how many times I clicked the mouse, tapped the buttons on the keyboard, or unplugged/replugged both (ALL of which, obviously, are things which would normally wake a computer up).
I generally just tend to keep the computer asleep when I'm NOT using it, wake it up when I need to, and turn it off/reset it whenever it crashes. And in THIS case, although I could still hear that it was running at full capacity--based on the nose the internal fan was making--I ultimately had to hold the power button down and turn it off after it wouldn't wake, and have turned it back on now.
Anyway, I've posted the problem report log below, if it tells you anything. Are there any settings I may unknowingly have it on in System Prefs, Energy Saver, Desktop & Screen Saver that I might not be aware of that causes it--or ANY computer--to do this??
Because as it is, and based on previous problems LIKE this, I have it set to "Never" go to sleep when it's inactive, "Never" put the display to sleep, putting the Hard Disk to Sleep is NOT checked, "Wake For Ethernet Network Admin Access" IS checked, as is "Allow Power Button to Sleep the Computer" (both under Energy Saver/Options).
Please help! Thank you.

Hmm. Sheesh, there are a LOT of variables that can go wrong with these MDD G4s!! (or at least mine). Insufficient fan, bad OS, bad drive.... oh well.
Well, the installed drive is one my family member (brother) chose pre-installed when he got the computer, a 111.79 GB model ST3120026A (not sure of the model) that I have separated into two 55.77 GB partitions. SINCE I am planning to switch over to a laptop anyway, part of me is thinking I MAY just take this opportunity to back this up onto a decent external teradrive, and transfer all of my personal files over that way. Still: if I DO still opt to get an inexpensive internal drive to keep this computer going, based on your own experience, what technical specifications do you advise me to look for??
And what is the best brick & mortar/online store you'd recommend for me to get a decent internal/external teradrive?? (I have a Fryes not far away, but I don't know if they're necessarily the best place to look...)

Are you able to bootup on your install disk?
Try using Disk Utility to repair your startup disk (hard drive) as shown in Dr.Smokes Resolving Disk, Permission, and Cache Corruption.
If it's a no wake from sleep issue, read on;
If your Mac happily goes to sleep but won't wake up--Hold down the power switch to force-reboot your machine and get it running again.
Don't worry-your Mac isn't narcoleptic. Its Open Firmware system or NVRAM (nonvolatile RAM) is likely corrupt, and your Mac can't remember how to wake up.
Restart your Mac and immediately hold down the Command-Option-O-F key combo until you see a somewhat intimidating command-line display that ends with the Open Fimware prompt. Type the following lines:
reset-nvram
press Return on keyboard
set-defaults
press Return
reset-all
press Return
Your Mac will reboot. Once it's running, put it back to sleep to test. If the problem recurs your Energy Saver preferences may be the culprit. Delete the com.apple.PowerManagement.plist file (go to Finder/Hard drive/Library/Preferences/SystemConfiguration)--don't worry, your Mac will regenerate a new one--and then restart to see if that rights the wrong.
Still did'nt work? Might be time to call AppleCare or see an Apple Genius or a technician.

Sleep - won't wake up, and now randomly goes off to sleep

Since the recent security update, my 1.67 G4 Powerbook has been experiencing problems with sleep. Sometimes it won't wake from sleep, forcing me to hard reboot or pull all power out, and now it's randomly falling into sleep when it shouldn't.
The issue is progressive - it will sleep, then I wake it, then it goes down again 2-3 minutes later, wake, then seconds, wake, then deep somnambulistic slumber.
I read in Macintouch that there was a fix recently for Intel MacBooks and sleep, but some of us in the PPC world are feeling it's effect.
I've reset the pram several times, and on one occasion the fan spun up very loudly on boot, then quieted down after 5 seconds. Might be nothing.
Another factor is the battery - pull the battery and the system behaves better. I wonder if there's a lowered thermal limit that, when the battery is charging, causes the system to shut to sleep...?
Anyone else having this problem? I'm ready to slip back to 10.4.9 to see if that makes it more stable -- this happens several time a day now.

For other who may be watching this...
The laptop did keep shutting down into sleep, but - following from a tip from another site - I began trying three things: One or all seem to have resolved the issue:
* Repair permissions - often and always. Something does get munged and I'd be interested to see if anyone else has the same files affected:
Permissions differ on ./Library/Widgets, should be drwxr-xr-x , they are drwxrwxr-x
Owner and group corrected on ./Library/Widgets
Permissions corrected on ./Library/Widgets

Permissions differ on ./usr/bin/fetchmail, should be -rwxr-xr-x , they are -rwxr-sr-x

Verify/repair finished permissions on disk disk0s3 Macintosh HD
* I stopped zapping the PRAM when it went to sleep or wouldn't stay awake on boot - I just booted from DVD instead and, lo and behold, the thermal errors didn't occur under the DVD. Fixed permissions and a reboot it often worked fine for hours.
* Running it alternatively from either battery or from mains. Initially under the battery, it would sleep at 70-60%, then - after a few days of being shut down instead of slept - it began running down to 0. I'd have to plug the unit in and charge it whilst off, but now -- after a week of this - everythings back to normal.
Ultimately, I'm sure this software. Something is up - and slowly, if you're patient, you can bring your system back without buying a new case or motherboard.

Mac air goes into sleep won't wake

MacBook Air goes to sleep as normal, but won't wake up now.

A new mini is on the way & I'm researching UPS's. A question that I now have is -
The new mini will have 10.5 which will be nice, but I really want to put my old hard drive straight into the new unit so I can have my old computer back the way I like it. Right now I have my external drive with everything on it plugged into my wifes macbook, & I can access everything except my email. The old emails are there in the folders, but as numbered icons, & I can't find anything. With my business I often have to refer back to old emails, & right now it's really hard to. I have tried to import them into mail, but it says it doesn't recognize them.
If I do this, can I put the new backup discs in & load leopard onto the old hard drive without loosing my old information & setup? We are on a very slow dial-up here, so I've never been able to accept the automatic updates. I look forward your advice.

Put to Sleep - Won't Wake Up!

The last two times I put the iMac to sleep, it would not start up the next morning. As per Apple's instructions, I removed the back cover and was able to re-start using the internal power supply button. After the second time, I just stopped putting it to sleep and it has been fine. But obviously I'd like to know what the problem is. My computer is one of the models covered by the extended warranty for faulty logic boards. Is this definitely the problem or could it be something else - and is there any way to find out on my own? Thanks!

Here's something you could try;
If your Mac happily goes to sleep but won't wake up--Hold down the power switch to force-reboot your machine and get it running again.
Don't worry-your Mac isn't narcoleptic. Its Open Firmware system or NVRAM (nonvolatile RAM) is likely corrupt, and your Mac can't remember how to wake up.

MBP goes to sleep, won't wake up!?!?

Recently my MacBook Pro has began going to sleep, either after not being used or after I shut it, and then it won't wake up and has to be restarted manually, which costs me data, time, etc.
I've researched the problem, but haven't seen anything that sounded exactly like what I am going through.
Plus I'm not the best at fixing stuff myself (lets just say I'm not going to get hired as a MacGenius anytime soon).
Help me! I'm writing my National Board Papers right now and need my machine to be reliable!!!
Thanks in advance.

I have just started having the same problem. I used to be able to use the MBP for a few minutes, leave it on the table and let it go to sleep. Come back anytime and it would wake. Now it won't, and I have to go back and plug it in to get it to wake. I have just now noticed that the battery is almost drained. I used to be able to do this for a couple of days without charging, and now it won't make it 12 hours.
The battery being almost drained would explain the no wake, but now the question is why it is draining so quickly even in sleep mode. Especially when I used to tell everyone how great the MBP is, and how long the battery lasts and how quick is starts up. Of course I was telling this to all my co-workers where we are stuck with the company issued Dell.
I think this may have all started after upgrading to 10.5 or iLife08, as those are the only two programs that have recently been added.

Random Sleep/ Won't wake up

Since installing 10.4.6, my computer goes to sleep after being on 15 minutes, sooner if I use a memory intensive program. Then, when I try and wake it up, it immediately goes back to sleep mode? Is this Tiger or my computer? Any ideas?

I'm afraid it sounds like your computer - a failing Power Supply Unit. If you have AppleCare, I would call them and arrange to take your computer in and have it checked out before the problem gets worse.
Please post back and let us know how you made out,
Miriam

Won't sleep, won't wake

I'm having two problems with sleep mode:
WON'T SLEEP
my iMac G5 won't sleep even though sleep mode is activated in Energy Save preference pane (file sharing off).
WON'T WAKE
When I put my machine to sleep at night (sleep item under apple menu), it won't wake up in the morning. The blinking sleep light indicates my iMac is in sleep mode. I hit a key to wake it. The sleep light turns off. Nothing else: no noise, no screen but the black on. I wait a few minutes and press the power button: nothing happens. Once it starts up after a hard boot (power button, 5 secons). Most of the time I have to wait an hour or two and then I can start up my machine by pushing the power button.
This problem occured yesterday for the first time. Today I did many test with same results: no wake after "manual" sleep mode and no "automatic" sleep.
Note: Apple Hardware Test did not detected any problem.

Even though the hardware test did not indicate a problem, you may still have one. I'd give AppleCare a call. Also note, if you are out of the one year or AppleCare coverage, you may still qualify for this program:

HT3231 Would it fatally interrupt my migration if I didn't set those settings and my computer went to sleep during the process?

help.

Why would you not want to set them and then find out? If Apple advises not to let the computer go to sleep when it is inactive during Migration, it probably will and mess things up. So just temporarily set it to never sleep and set it back to your usual setting when the migration is done.
