If I close my computer lid with a Flash video paused, the computer refuses to go into sleep mode, and locks up entirely. No amber light is elicited to indicate sleep, but instead the blue light indicating my screen is still active remains lit. This forces a hard reboot. All of my drivers are up to date, and Acer is washing their hands of this bug as far as my experience with their tech support goes.
I have not tested the RAM yet, but I would be surprised to find if there were any errors. I will go ahead and do the test anyway, but any other suggestions are much appreciated! The only thing I remember doing was to do the 'Automatic Updates' following which I rebooted my laptop. Ever since, I've had this 'Blank Screen on Resume' problem. I have had this problem for many months now. I have not been able to determine the root cause but I have discovered a workaround.
While closing up that evening on a fresh installation of Win7 Ultimate I decided to allow Windows to update as it shut down. Booted the next morning no prob, put it to sleep and Black screen. The fact that I was updating Windows and drivers on my new build makes me believe it has everything to do with the an update that possibly conflicts with a driver on the D Attempts to reinitialize fail.
Start over rebuilding. I rebuild the original and don't even get all the way through the build when Windows Update reboots and on testing the system gets a black screen out of sleep. One curious thing: This time I notice that I get a "good" cursor but otherwise black empty screen. The "good" cursor -- a high resolution cursor, not a an x ugly pixelated cursor -- makes me think the video driver has initialized but Explorer is not coming up.
Event logs show the system initialized properly with no real errors other than some HW drivers I didn't install. I'm forced to move on and get a Dell E I install Win7 Ultimate bit retail that I had lying around.
Considering I was already limping by with my old D and a broken Win7 D I decided to figure root cause. This story is long enough so I'll cut to the chase. I could never consistently recreate the issue. At the black screen with a "good" cursor I force a cold boot, hit F8 on the to boot. Select Safe Mode and reinstall my video driver. Reboot to normal mode. Working again. No more rebuilds, thank God.
Regarding the blank screen on wake up from sleep issue, I have Windows 7 ultimate on a Lenovo T, and finally found the graphics driver was causing the issue. See the following article:. My back light fails to restart after a resume from sleep. This behavior started a few days ago after a windows update.
When I start up my HP dv7 notebook after a sleep I can clearly see the windows 4 panel glowing logo - back light is clearly working. Then the back light goes out. The machine is running normally - I use it if I connect an external monitor. I see this thread is old - if you get this far down on this page this might be the anwser you are looking for.
My back light fails to restart after a resume from sleep closing the lid. The machine is running normally - I can use it if I connect an external monitor. I have updated the ATI drivers update but this did not help.
Installing HP drivers seems to be the fix. What I have discovered is if I re-close the lid, repeat plugging the power in and removing it seval times, then opening the lid the back light activates. Been working just fine. Since the past weekend every resume from sleep has gone badly. Never had that happen before. Sometimes it comes on but the screen stays black.
Disco'ing the USB3 drive doesn't help. Forcing a hard power-off and restart doesn't help. Turning off the power to the case doesn't help. The one time it sprang to life was when I unplugged the two transceivers and used an old Dell USB keyboard straight into one of the ports on the front of the case instead of the wireless devices via a USB hub on my workspace.
The system was hung as usual, then a few seconds after I plugged in the Dell kb it came to life. Prompted me to nuke the existing state info and startup, which it did. After your machine resumes from sleep with no backlight turned on, try putting it to sleep again close the lid unplug the external power, wait 30 seconds, open the lid - if your machine still does not have a backlight after resumeing - now plug the power in and if that fails unplug the power and plug it back in right away.
I have tried a number of different combinations and there seems to be something about closing the lid and unplugging the power before sleep is complete.
Thanks for the suggestion. Was useful in a certain way. The machine is a desktop with no onboard video if I recall the mb spec. In hindsight that choosing mb without native video was a mistake on my part. Did try disco'ing the power and letting it sit for a few minutes before switching the power back on and booting. This time something different happened - the machine showed the basic bios boot screen for a couple of seconds and then Windows appeared and announced a resume from sleep - so far so good.
But then the monitor goes black except for a flashing cursor in the top left corner for a couple of seconds and then everything dropped dead - fans stopped, usb ports lost power, etc. But the activity led on the monitor continued to glow blue as though it was receiving a signal. I forced a restart rather than power off using the hard restart button on the front of the case and it booted perfectly - prompted me to kill the state and then proceeded normally.
Perhaps this one - it's the only one that was installed last week that looks vaguely relevant:. This article describes an update for Windows 7 and for Windows Server R2. This update contains the following new functionality, performance improvements, and solutions to issues:. I built a desktop for myself and one for my father, both with windows 7, but not all hardware was the same. I have never experienced the monitor not waking from sleep but my father does about once a week as described in most of the posts above.
I changed my father's machine to "yes" and his monitor seemed much more responsive coming out of sleep mode. HP slimline sf with Sapphire Radeon lower power graphics card and 2 monitors. When resuming from hibernation, I get 2 black screens and a solid cursor that can move between monitors, almost as if nothing's wrong. Same problem with a previous high power GeForce GS graphics card. The problem seems to occur more often when I bring the system up in the morning, vs.
I am experiencing this exact issue on one of my PCs at work and the hotfix that was presented previously was not valid for this issue. That KB article has the title as "You cannot make a computer that is running Windows 7 shut down or sleep". That is the opposite of the issue I am having.
I am unable to get the computer to come back from sleep and the symptoms are the same as the poster thebigdintx discribed.
I am at a loss at this point as to how to fix it. The computer has Windows 7 64 bit with SP1. I have turned off hibernation until I can find a fix. I'd hate to halt moving to Windows 7 based on this, but I am at a loss at this point as to how to fix this. I definitely need to have hibernation on for obvious reasons.
Any other updates on this, Microsoft? I too have been getting this screen sleeping disorder, but found a different way than forcing a hard reboot to make the symptom go away. Perhaps this example will be useful to others who continue to be frustrated by this issue, or help someone solve this problem.
While it looked like a video hardware problem when I first experienced it, it continued after updating my ATI HD driver. I essentially make the problem go away by closing open applications for 10 seconds at a time until the screen sleeps again until the screen finally stays awake. Here are my steps: After awakening from sleep mode my Win7 screen is fine for seconds, then occasionally the monitor goes black. This has been happening for a month, but not every time I awoke the system from sleep.
To address the problem I press the monitor's power button OFF, then back ON, and the screen awake again, with my desktop displayed as it was before the screen went black. That is only good for 10 seconds, then it blanks out again. So, I started using the ten seconds of a working display constructively by shutting down applications one at a time. Specifically, when I closed Excel , the display stayed on! When I restart the applications the problems to no reoccur.
If I close Excel before letting the PC go into sleep mode, then I do not get the problem when awakening from sleep mode. I have an 8 months old A cer Aspire running Windows 7. A few weeks ago, small areas of corruption started appearing on the log-in screen on waking up from Sleep or Hibernate mode. These consisted of fine, slightly wavy multicoloured horizontal lines, in blocks a couple of cm wide and varying depths.
However, after logging in the corruption disappears and everything is normal until the next Resume. The problem became more persistent, with larger areas of corruption, until finally, a couple of days ago, the entire screen was evenly covered with this stuff and I couldn't get a response from any key combination, so had to reboot by pressing the on-off button.
This morning, on Waking, the screen flashed momentarily with the corruption and then went blank. I have now rebooted. This clearly isn't limited to a single make of computer. I'm not inclined to believe it's a problem with the screen, cable inverter, graphics card, motherboard or indeed any hardware.
If it gets worse I will. Curiously enough I had a screen problem with an earlier laptop — an HP dv — which for many months corrupted or black-screened, and ultimately failed to recognise the internal monitor, but worked with an external. Tried all sorts of things including rebedding screen connections, different drivers etc, all to no avail. Then suddenly out of the blue, a few weeks ago, it started working perfectly again and I haven't had a problem since!
So I'm inclined to think this might all be related to Microsoft updates, simply because they're the most obvious major change factor other than the AV — Kaspersky. All extremely baffling, and clearly widespread with no apparent resolution. I had to make a name and register so I could help you guys.. I had it set to off earlier. There is also a setting for moderate power savings but it's been working on maximum so i'm not going to mess with it. My machine wakes if the power is plugged in or not back light would sometimes fail if I plugged the power in before wake was complete.
I am using a Dell Latitude E and have been having the problem with waking up my system after it goes to sleep. It typically happens when I close the lid.
I have tried numerous fixes and none seem to fix it. Finally I tried something over this weekend and it solves it for me. Hopefully this will fix it for a few other people out there. Hope it helps others with the same problem. I tried many suggestions with no luck. What I can do for now is changing the settings to turn off display after 5 hours, and choose High Performance for power option in control panel.
After sleep mode the screen becomes black but with black-light , the computer do work I hear notifications and I see working led's and the only solution to get back the images on the screen is to fold it and re-open it or shutting it down and back on!
Same exact problem, only I have to pull my video card out, start the computer and then restart, put the card back in for monitor to get any kind of signal, switch video cards and got the exact same problem. Ive just been shutting down my computer at night and upped the hibernation time for like 4 hours. Kind of a pain in the behind, especially since this computer is under a year old.
Running Windows 7 Premium, going to try the hot fix when i get home. I installed Win 7 Ultimate. After doing updates which included an NVidia driver the problem began. After reading your post, I went back to HP, and downloaded their Nvidia Vista driver they don't have drivers for win 7 for this old lappie, but the vista ones work as 7 and Vista are so similar.
Once the HP Vista driver was installed and I rebooted, the problem instantly resolved. Office Office Exchange Server. Not an IT pro? Resources for IT Professionals. Sign in. United States English. Ask a question. Quick access. Search related threads. Remove From My Forums.

I have to force a shutdown twice, then it gives me a choice to delete the restoration and proceed to bootloader or something like that. Known issue? Any fix yet? Running an Nvidia GT with latest drivers installed about a week ago, so maybe a compatibility issue with the graphic driver? Edited by thebigdintx Thursday, December 10, PM. Friday, December 4, PM. Take a look at this KB. I already ran a fix from Prevx with a tool they offer here I would try applying that hotfix if you're still having the issue.
I wonder if the prevx tool does the same thing the MS fix does for the issue? I hope MS issues an update on windows update that gets it all fixed soon I'm fighting the same problem on a new PC.
It was initially resolved by updating the BIOS to the latest version. I've tried the Prevx tool, turning off hibernate, etc. I also enabled hybrid sleep for the heck of it. So far two resumes have worked properly. With all the kerfluffle surrounding Prevx, recent black screen issues after patch Tuesday, I'm not convinced the problem is fixed, but wanted to add my results.
Hopefully it might be of help to someone else. Monday, December 7, PM. Gavin and bigdintx, There is another forum thread talking about a similar card. I don't expect the Prevx tool to do much for either of you here.
Does the video card have the latest BIOS installed? Have you tried the latest drivers? Do you by chance have another video card you can try? Just to test and see if the behavior goes away when you change cards? Thursday, December 10, AM. This issue is different that the one you linked to. I've had Windows 7 installed and running no problem for months where this person had trouble during the initial installation. I also have the latest video card driver installed as I mentioned in the first post.
Thursday, December 10, PM. Forced another shutdown, and greeted with notice that resume failed and 2 choices of resume or delete restoration and proceed to load windows or something like that. I deleted the restoration and it then booted into windows.
Wednesday, December 23, PM. It sounds like it is pretty widespread, but other descriptions left a lot to be desired.
I recently bought my gf a Samsung N and it was working great after the windows install though it did seem to 'shutdown' instead of sleep , and the last thing I did was install windows live messenger so that her hotmail would save multiple e-mail addresses. I shut the netbook and take off for two weeks, she comes home, opens it, and black screen of death. When she called me, I thought she was joking. Exactly as you described it, flashing cursor, the two options Given how widespread this is I'm running a netbook maybe microsoft will come up with a fix.
Is there anyways to bring this to a technician's specific attention? Good luck thebigdint, haha maybe we'll get this worked out. I had my gf install the new BIOS one thing I didn't do and it hasn't happened since then, but it only happened that one time anyways. I just bought the same netbook and will be installing windows 7, so maybe I can figure it out. There has to be a way for microsoft to fix this. Saturday, December 26, AM. Did that near the beginning and it didn't cause problems as far as I could tell.
I get the same problem on my new Asus HA B. When resuming from hibernation or sleep, I get about 5 seconds of normal screen video, then it goes black. The computer is still functional though, as I can still hear audio notifications of events. Only a reboot escapes the video loss problem. So I know the hardware is not defective. In fact, before I did the MS updates for Win7, it worked fine too.
But I'm not about to go through uninstalling the dozens of updates to find out which one is the culprit. It took hours just to get them on. I'm happy to provide the list of updates though if someone knows what to look for. I've heard of Security Essentials causing problems with Black Screen of Death, but it's possible it's only one of many triggers for a deeper problem.
I'll uninstall that and see if the problem resolves itself. Edited by scampcat Thursday, December 31, PM update bios number. Thursday, December 31, PM. Well I think we can rule out Security Essentials. Removing it changed nothing. I also increased my pagefile to 2GB. No change. Disabled advanced power features of the Intel Graphics card. This makes Windows 7 on a netbook absolutely worthless. It happed again yesterday Don't know if that would make any difference, but I updated regardless.
It used to run Vista Business and I had no issues. The machine is still active and I can remote desktop in fine and no errors appear to show apart from the warning mentioned below. I actually increased it to several times to see if this made a difference. The problem changed First sleep is now fine and screen restores correctly.
Second and subsequent sleeps fail to turn display on. I get these info messages in the System log on wakeup - but not necessarily every time the problem occurs but most of the time : The speed of processor 1 in group 0 is being limited by system firmware.
The processor has been in this reduced performance state for 6 seconds since the last report. I get one of these for each of the 2 processor cores. There's no cooling problems on the laptop causing these. I've restored the pagefile settings back to system-managed - and the problem's stayed the same!
I've tried everything I can think of. It does it in safe mode and in Clean Boot with non-Microsoft services disabled. Absolutely everything points to a Win 7 problem or some sort of ACPI corruption issue or a mixture of the two. Saturday, January 2, PM. I got same problem with my HP laptop. Every time windows tries to restore from hibernation file I got black screen and nothing happens.
Looking forward for the hotfix Sunday, January 3, PM. Happened again this morning. Seems to occur after being in sleep mode overnight, so maybe when in hibernation? Monday, January 4, PM. I get problems every time. In my case which sounds different to everyone else! On investigation it doesn't appear the system is fully resumed on the second case. After resume the first system log entries I tend to see in addition to the processor throttling messages not always are netbios service starting, then it receives a stop signal and netbios stops.
That's pretty much the last log entry til I have to force a shutdown. Only one driver is in Vista compatibility mode and that's the camera on a laptop. I may have found something I was reading on another site that Windows uses a different registry setting for the Resume function than the OS Boot for video. Essentially, video Device0 is correctly identified and labeled in the bootup registry settings, but something about the Resume registry setting either is pointing to the wrong device, or no device at all.
So Booting up runs properly configures the video, while power-saving or Resume or Video registry settings may be missing key information to properly recognize the right device for resuming continuous power after Resume. Is this making any sense? Anyway, I removed all video drivers from my computer so that I'm back to a crappy resolution. I don't know a great deal about these particular resume and video registry settings, so I'll keep digging. I should get some info.
But if the manufacturer forgot to add the registry settings for the Resume to video, I won't get too far off that. If I've spawned any "aha moments" in anyone, please help out.
If I'm off base, let me know. Tried the manual PageFile increase with no luck, etc. No problems with devices or apps. I don't really need all the whizbang stuff, eg Xbox Skype etc. I'm a simple person. My biggest concern with these new machines is the high-gloss monitor -- I wear spectacles and have always had difficulty looking 'through' such high reflective surfaces, whether on a framed picture or on PCs. It is exhausting for the eye. I am surprised that the PC manufacturers would even consider using such high reflective surfaces for this reason and am very disappointed with the product offerings as a result.
I think it should still be possible to make a machine with the LCD screen, hardened somehow to be usable as a touch machine.
Will Microsoft tell me all the things I need to do to get my machine ready, in plenty of time before downloading? I'll have to increase it in time for the download. I don't agree with that advice, as the Microsoft notification scan has shown that there are no issues with any of the apps installed on my machine. It should just upgrade over all that. I would, however, exit the program and also disable some of the Startup programs.
In my view, that should be enough, other than what Microsoft tell me themselves, referred to in my question part b above.
