Can't wake up after sleep mode

Mac owner for 2 months now and have had no problems till today...had to reboot to wake up from sleep mode...one time occurrence or start of an issue?

That's an important one. Let it finish normally until you are fully rebooted and things are stable.
Whenever I get a firmware update like that one, I follow nine steps to ensure my computer is in top shape. Basically, they represent checking the disk for errors, fixing the errors, fixing the permissions, and setting the default memory values to whatever was in the firmware.
1) shutdown the computer
2) push the power buttom and as soon as you hear the chime, hold the option key and don't let go
3) when you see your boot options, let go of the key and select recovery partition (Lion only)
4) select disk utility from the options, then highlight Macintosh HD, do a repair the disk and repair permissions
5) now click the apple icon in the upper corner and shutdown
6) pull the power cord and hold the on button for 15 seconds
7) plug it back in, and find the option, P, command, & R keys
8) hit the power button and as soon as you hear the chime, hold all four keys (it takes two hands)
9) wait until you hear the startup chime twice and let go, allow the computer to finish booting
I'm not recommending you do it, it is just what I do. Good luck.

Help me!!!!!!My iBook 800mhz sometimes can't wake up after sleep mode...!!

Hi everybody. I'm a happy mac user sinc 2001, and i have since 2004 an ibook G4 800mhz. Ok, everything good, the problem is that from today if i leave the ibook in stop mode for half an hour for exemple it can't wake up, everything seems dead and i have to push the power button for 4 second and then turn the computer on again. If the sleep mode duration is about 5 minutes ok, otherwise it can't wake up. whyy???? what is the problem? i reset pram, nvram and pmu, but nothing. everything else works perfectly, but this is a very important problem for me because i risk to lose my work because i have always to reboot the system.
Pleas help me!!!
Ps i'm sorry for english, but i'm italian...
thanks a lot

annihilator,
Quoting from my own post:
""It could be a PMU problem. The PMU is actually a tiny computer within the computer. It's official designation is PMU99.
http://developer.apple.com/documentation/Hardware/DeveloperNotes/Macintosh_CPUs-G4/12inchPowerBookG4/2_Architecture/chapter_3_section4.html
"Power Control IC
The power manager IC in the 12-inch PowerBook G4 is a Mitsubishi M16C/62F microprocessor, also called the PMU99. It operates with its own RAM and ROM. The functions of the PMU99 include:
*controlling the sleep and power on and off sequences<</div>
*real time clock
*controlling power to the other ICs
*monitoring the battery charge level
*controlling battery charging
*supporting the interface to the built-in keyboard (AND TRACK PAD)
The PMU99 also provides the hardware interface to the keyboard. Software in the PMU99 IC scans the keyboard, then sends the data to the system in packets like those from the ADB. To the system, the keyboard behaves as if they were ADB devices""
Try resetting it:
http://docs.info.apple.com/article.html?artnum=14449
If that doesn't work try what I call a deep PMU reset.
Pull all power including the battery, push the power button to remove residual charge in soft start capacitors.
Then walk away from it for at least 10 hours.
This has worked for Macs with the PMU99 since the G3 Desktops and especially the G4 Towers (Sawtooth, GI, MD, etc)
Also:
i had a problem with trackpad that became crazy, but i unmount it from the case i clean it and now it works better than perfecty.
Could you explain this more clearly? You opened up the iBook, then
i unmount it from the case
so you removed the trackpad part itself from the upper case? the trackpad part and associated circuitry? Was it glued to the upper case? in that kind of little well it sits in? But you didn't break the plastic welds that hold the "clicker" part to the upper case?
i clean it and now it works better than perfecty.
Which part was dirty?

X505-sp8915r wont wake up after sleep mode

My laptop wont wake up after sleep mode (suspender). The laptop does everything it should like the red lights go off but when i hit the power button just the power red light goes on... The keyboard backlights if I try using it but the monitor wont show anything and the hard disc red light doesn't even blink.
Hibernation seems to be working fine. I had to change all that will make my computer enter sleep mode to hibernate. But I would like to get that fixed. I read something about the bios and my version is "BIOS Version: V1.40. 12/04/09.

Qosmio X505-SP8915R
The BIOS is up to v2.2 now. It's possible that will help.

Memory RAM upgrade won't wake up after sleep mode

i just recently purchase a pair 16GB RAM of crucial CT2K8G3S160BM for newegg.com. Yeesterday i try put this on my macbook i7 intel 2.9 processor that crucial said is compatible. but found out everything was good until i close my mac lid for hibernate. What happen is, it won't wake up no matter what i do until a way of reset SMC. BTW i try stick by stick to plug in together with my original 4gb RAM together found out 1 was ok and other one was not. But somehow why the info of hardware show that memory ram 16GB was installed and was OK. Everything was run smooth even booting. The only problem is won't wake up after sleep mode. I already try reset smc, pram, delete startimage, delete powermanagement.file and also sudo hibernate 0-7. Did anyone had this same issue of me. I'm my curiousity will it be the bad ram or software problem.

i just google around and found this two both crucial ram. Both spec are the same but different model no.
CT102464BF160B 16GB and mine is CT2K8G3S160BM are this 2 same? but both same spec.

Monitor won't wake up after sleep mode

Does anyone know how to fix the monitor, so it starts up after sleep mode? When my computer comes out of sleep mode the monitor doesn't always come on. Does anyone else have this problem and do you know the cause? The computer is only a few months old and hadn't had any problems.
Thanks,
Shaneil

Well my solution may not be the most cientific one but it works for me (at least until the real solution comes to the public)...
My computer has the problem that when it goes to sleep mode she never comes back... but it the screen that does not comes back... all the system is workin in behind (its like the brightness level was set on the less power possible) so i had to turn off the computer and had to do for a long time some times i had to wait that the computer cooled off a little and then try again to turn it on... I some tried things that the support page of apple said it could be... but did worked out... i dont know i think is a problem over 2 factors...
1. heating (the screen generates to many heat but, TO MANY!)
2. tiger os the OS "sleep mode" (it knows that the screen its heating a lot and tries to go to sleep to prevent over heating and damage)
So based on this i tried conecting a external monitor to the computer while she was unable to "awake" (or to show some thing in the screen)... and it worked whit no problem at all... so my conclusion was to prevent the over heating (1st factor) and the sleep mode (2nd factor)... so I deactivated the sleep mode setting up the computer to a never sleep mode... and to prevente the over heating well I use a low bright and when i need more brightness (to se the colors of what im doing or some thing like that) I use high brightness... when I away I set the brightness level to no brightness so there is no over heat and no sleep mode (cus if it is deactivated and it over heats it will go to sleep anyway...
Soooooo....
1. deactivate Sleep mode...
2. Activate a Screen saver...
3. And remember to contro your brightness your self... and turn it off when you are not using your computer...
well i hope it works for some body :P cya...

HP Envy Laptop will not Wake up from Sleep Mode with Windows 10

The reason I decided to go back to windows 8 was because since upgrading to Windows 10, when my computer goes into sleep mode, I cannot wake it up. I have to press and hold the power button to shut it done and restart. Even if I close my laptop, and reopen the lid, it wont start back up and I have to press and hold the power button and shut it down and restart. After trying to restore my HP Envy Laptop from Windows 10 to Windows 8, it got stuck in a Repair PC Loop and I could not even access the desktop, I tried the restore option to an earlier date and that failed and all the repair options also failed. The last option I had was to do a full PC Refresh, and that one worked. It took about an hour but no data was lost, and only a few of my downloaded apps were removed. An html url was left on the desktop that showed a list of all the apps that were removed. So all I did was download those back and now im back up and running Windows 8. I want to re-download Windows 10, does anyone have a fix for this issue?

Hello mistyb1,
Welcome to the HP Forums.
I see that you are having an issue with the printer not waking up from Sleep Mode.
I do have a few suggestions that we can try.
First off, please make sure that you have the printer power cable connected directly to a wall outlet and not a power bar/strip. Here is a document that uses a LaserJet printer as an example but it is meant for HP products in general. Please click on the following link that explains the Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector.
Once you have the printer connected to the wall outlet, please use the ON/OFF button to do a proper power cycle. This will do a Semi power reset on the printer.
If the troubleshooting does not help resolve your issue, I would then suggest calling HP's Technical Support to see about further options for you. If you are calling within North America, the number is 1-800-474-6836 and for all other regions, click here: click here.
Thanks for your time.

Laptop won't wake up from sleep mode

I have a Satellite L745-s2410 and usually whenever i close the lid to my laptop it goes into sleep mode and the orange light comes on and whenever I open it up again it would come back on (either automatically or just by moving the mouse or pressing the power button). However as of last week I noticed that when it goes into sleep mode it only comes back once. If i put the laptop to sleep again it will not come back and I am forced to either take out the battery or hold down the power button to turn it off. If you can please help me that would be great
Thank you in advance,
Eric

Did this just start?
Try this. Turn off your laptop, unplug all wires, remove the battery, and hold the power button for thirty seconds. Afterwards, reattach the battery and connections. Then test it again.

NEW iBook and doesn´t wake up after sleep mode!

Hi,
I´ve just started to use my new iBook G4 3 days ago, added my user information, and for a little while the wireless internet connection. Then, I closed the display to put it on sleep mode.....and.............it DOESN´T WAKE UP!!!
The hard disk seems to start up correctly (the fan is on and the disk noise is ok), the Caps Lock on the keyboard is on too, but as soon as I reboot the computer, a strange beep (like a phone tone!) starts up, then the sleep light signal flashes but the screen stays black.
I think that by now I´ve tried the most solutions (as far as I can having the black screen) I´ve read on the troubleshooting page and the recommendations posted in this Discussion chat... The iBook remains partially dead.
Help!!!

ummm, even when its not plugged in to the power adapter? i find that when my ibook annoyingly doesnt wake from sleep, its usually because i connected/disconnected something while it was sleeping. even plugging in the power adapter seems to affect it. the way i fix it is to put it to sleep again, and then open the lid. its worked every time so far.
oh, and apprantly 'manually' putting the ibook to sleep does the trick (ie from the apple menu)

Screen won't wake up after sleep mode

I bought the new Macbook Air 13" a month ago, and I got a problem with my screen display recently. This is the second time in a week. It went to sleep mode and when i opened the lid, the screen was still black as usual and no matter what i pressed (I tried touching and clicking the track pad as well), nothing happened. So i ended up pressing down the power button to restart it. The only thing I could do was to report this problem as it just turned unresponsive after the sleep mode.
Has anyone encountered the same problem as I did?

I'm having this exact same issue with my wife's 11" MacBook Air (July 2011) we just bought it last weekend and she's frustrated with the issue.
I have none of these issues with my 13" MacBook Pro (March 2011) which frustrates her even more, she wanted the Air because of the portability, but she's not very happy with this issue.
I imagine if it were a bug with Lion it would be present on my MacBook Pro, right? so I can only think is a firmware issue.
Hope Apple releseas a fix very soon!

Nokia won't wake up after sleep mode! ( Work aroun...

WCH1.... Posted this in my first thread
Found this somewhere, and it worked for me.
Freezing in sleep mode:
Go to the device manager (you can go to control panel and click on SYSTEM and then device manager will be in the upper left corner). Go to the very bottom and find Universal Serial Bus controllers.
Click on the arrow next to it and it will reveal 2 "USB Root Hub" devices. Double click (or double tap).
On each one, choose Power Management tab from the top. Uncheck "Allow the computer to turn off this device to save power". Then click on OK.
Be sure to do this on both device ISB Root Hub listings. ( The Credit is not mine) but much needed because they keep posting in my first thread !

Can't wake up after sleep

I bought a Macbook (15-inch, Late 2011) at Amazon on April 26, 2012, and I made it to be my primary laptop.
The Laptop is wonderful but sometimes I got a problem. After finishing the work I will turn my Macbook into sleep by pressing the sleep button under the top-left apple menu. However, the next day I found I have no way to wake it up, neither the keyboard nor the mouse would work. Even the power button fails to wake up my Macbook. Unless I force the Macbook shut down by long pressing the power button, and restart it again.
Such situation happened to my Macbook many times when it was fully charged. The problem is quite annoying and discouraging. Is it the common problem of Macbooks? And how can I deal with the problem?
Thank you.

Fan

X120e 0596 screen wont wake up after sleep mode until unplug it and remove the battery

I recently purchased a Thinkpad X120e (0596) and am genneraly very happy with it however when it goes to sleep the screen does not wake up when the laptop does. when i wake it up i hear the fan spin up but the the screen remans powered off. ive tried waiting several minutes and it still doesnt wake up, ive also tried holding the power button for several (more than 5 ) seconds to force it to power off fully then start it again and the screen still doesnt wake up. the only way i can get it to work again is to make sure to unplug it and remove the battery for several seconds then i can get it to boot with the normaly expected complaints from windows after an abnormal shutdown.
I have the latest updates from lenovo and microsoft installed including the latest firmware. I like the laptop so i would rather report the problem and provide any information neccisary to find a resolution than have to return it. Ive seen this problem with other laptops before and know its probably a bug in the firmware thats not waking up the GPU is ther any tool i can use to provide the debuging info or any more direct way for me to report the bug I tried calling customer support and they told me they told me my only option was to return it and they could not report or record the issue.

Same issue here, confirmed many times in linux, will likely recur at some point now that I am on windows (8). The event log from the HAL says "The platform firmware has corrupted memory across the previous system power transition. Please check for updated firmware for your system" even after successful suspends, so who knows what happens when it fails. Since it's video-related, the problem could as well be in AMD's driver (also hinting at this is the fact the system periodically freezes when the screen is simply turned off from being idle).
Also worth noting is the fact suspend seemed to work just fine on my system with the factory BIOS (1.08), with the issue appearing only in newer ones (the oldest one still available for download is already affected, and I am running the latest one). There are also slight differences in the issue between the legacy and UEFI boot modes, but none of them mitigate it.

MacBook Air not wake up after sleep

Hi,
My MacBook Air(Mid 2012) can't wake up after sleep. I recently updated operation system to Mac OS X Mavericks and now after sleep mode screen goes black and nothing happens after this. Only thing that I could do is hard reboot by pressing power button and boot again. Do anyone have the same issue and suggestions how to fix this?
Thanks in advance
Dmitrii

Same thing here. MBA 2011 working perfectly until I updated to Mavericks.
It often doesn't wake up fully. It does draw the password input box but there's no text cursor and no input is possible. The mouse cursor is not visible either. Waiting does nothing (tried ~15 minutes, no change). Closing the lid does not put the laptop back to sleep, it's fully frozen and the only way out is a reboot by holding the power button.
