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...

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.

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 !

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!

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.
ACPI Flash BIOS version 2.20 for Qosmio X505 (PQX33U)

Won't wake up from sleep mode

I have only had my iMac for a couple weeks and four times now it won't wake up from sleep mode. I have to use the on/off button for a response.

Since you have a new machine, I would call Apple immediately and have them deal with the problem.

X1C won't wake up from sleep mode using keyboard

Hi...so finally got my X1C today. One thing I am noticing is that the machine won't wake up from sleep mode when I press any key on the keyboard -- it only wake up by pressing the power key. This is a bit unexpected to me. Is it by design, and is there any way to change this?
Thanks for your help.
Solved!
Go to Solution.

Does it awaken from stand-by if you press the Fn key? That's been the ThinkPad standard for as long as I can remember.
Regards.

Macbook Air 2011 won't wake up after sleep

My Macbook Air 13" 2011 won't wake up after sleep. I've taken it to apple genies bar, but they offered to replace my logical board!
I bought the Macbook Air in last August. Why cannot they replace a new laptop???

One thing you want to do is "Repair Permissions" in Disk Utility before you upgrade to a new revision, and afterward do the same thing.
On occasion files will become inaccessible to the logged-in user and cause certain components of the OS from acting cooperatively. This can most often happen during/after an update. Also, by resetting permissions before an update, it is to ensure that the update process itself can accomplish all tasks.
You may also want to consider applying/re-applying the downloaded 10.7.3 "Combo Update" from the Apple.com/downloads/ section. After resetting permissions, of course.

1G iTouch won't wake up after sleep

1G iTouch won't wake up after sleep. When I plug it back into my laptop it does a complete reboot. Tried both reset and restore. Works fine as long as plugged in. It shows a full battery and drains properly but once it goes to sleep it acts like battery is fully discharged.

Is the iPod or the laptop going to sleep?
I can't tell for sure from your post.
When you restored, was it "as a new iPod" or from a backup?
What software is on the Touch?

Monitor won't turn on after "sleep"

Hi,
I have an Apple Studio Display 17" hooked up to a New Mac Pro, running 10.4 Tiger. When the computer goes to sleep the monitor won't come back on when I wake it unless I shut the monitor off and turn it back on again. Why?
Dan

What did ssh probing tell you.
Try using PC blindly. For example, leave music player on screen, wait for the fault to appear and than start it. If you hear the sound, then it is either:
Your closed-source driver mistake. Try changing it's version either side or replacing with open-source one. For radeon it is really better already.
Your monitor can't wake up from sleep. Nothing can help it, then. When rebooting PC, it gets a special signal, different from that on sleep.

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.

MacBook Air won't wake up after sleep

I've been reporting sleep problems with my iMac for a while in the past. No-one here would take it seriously (probably hardware, your reports are incidents, no-one else has these problems) so I just went away and I disabled the sleep function of my iMac alltogether, and I won't select the "sleep" button in the login screen anymore, or select "sleep" from the apple menu. No sleep no problem, right?
*Well, I bought a Macbook Air three days ago, and in those three days I have had TWO occasions already where I wanted to wake the Macbook after sleep* (closed lid) and it wouldn't wake up. All I get is the rainbow mouse pointer and the Macbook is unusable unless I reboot it.
Mind you, nothing is connected to the macbook but the power cable, and I find it hard to believe that my Macbook Air would also suffer from 'hardware problems' like my iMac alledgedly is.
In all my time using OSX 10.4 on my 17" PowerPC MacBook pro I have never had any problems, but since switching to Intel Macs with 10.5 I have these "sleep" problems all the time.
What gives, and can I expect Apple to do anything about this problem that I've been having since I bought my iMac more than a year ago, and is now also spoiling my MacBook Air experience?

I have a Macbook Air and it also frequently (6 times out of 10) will not wake from sleep mode, only way to revive it is to hold down power button for 10 secs and force a restart. VERY FRUSTRATING!
I also occasionally use an external Apple 24' Screen (Non LED) and find that the MBAir will often freeze when you plug that into it or unplug it from it.. Perhaps I have a hardware fault on the MB Air? Or will this be fixed in software?

Macbook Air 13" Mid2011 won't wake up after sleep again after replacing logic board

I have replaced my logic board a few days ago for the issue of not waking up after sleep.
It was good when I was in store and the same night.
1 day later, when I put the laptop to sleep by clicking the sleep menu item, I cannot wake it up by all means in the next morning!!!!! Again!!!!!
I hooked it with a 22" LCD monitor via thunderbold to HDMI+HDMI to DVI. Will that cause issue?
I'm not sure when this will end, I cannot just keep replacing my logic board!

Satellite T230 - Won't wake up after sleep

I'm struggling with a problem on a new T230
After the machine goes to sleep, with Keyboard Wake enabled, it won't wake up no matter what I do. The only way out is to close it and restart or set it not to sleep, which undermines the main reason I bought it, the claims of long battery life
Any assistance will be most welcome

Hey,
Do you notice the same behavior when Wake on Keyboard is disabled?
Are you using the preinstalled Windows 7 from Toshiba?
To be honest its really strange that sleep mode doesnt work properly. I use often sleep mode and hibernation very often and it always works but I disabled Wake on Keyboard to safe battery power while its turned off and I have installed newest BIOS version from official Toshiba website.
Do you have newest BIOS version too?
