+ 1 Votes This is quite normal OH Smeg 1 year ago It can be a result of a Windows Update applied recently breaking the Hibernation or Sleep Recovery modes to something like a Out of Data Driver or just that the current version of Windows + Patches no longer supports your exact Hardware for this option. You should look on the system makers Web Site for any fixes to see if they have a solution. Col + 0 Votes Good News haxdnoob 1 year ago On Saturday, the 10th of November, a power outage happened while I was sleeping, and after I woke up, I ended up trying to turn on my computer, it didn't turn on. It was my dad's opinion that the power supply and motherboard got fried, so he contacted dell to get replacement parts sent over with a technician to install them he came 3 days later, and when we opened up the chassis of the computer, there was a ton of dust from not cleaning (which probably contributed to the non-functioning computer; yes, a bad on my part for poor computer pairing). After cleaning as much dust as we could get, the technician replaced the damaged parts with the newer ones, booted up my computer, then profit, it worked The motherboard I now sport is apparently a newer model as instead of a giant blue lettered dell logo, I get a smaller silver dell logo. I checked to see if I could put this in sleep mode and boot it back up successfully, and it worked, so thank you guys for helping me with this, WGnC, you were right that it was hardware related, and bye for now peoples + 0 Votes Like Col said this is so common that most Charles Bundy 1 year ago manufacturers have checklists. I've posted one below. Even tho it is specific to HP/Compaq the troubleshooting steps are all Vista based so should be hardware independent. http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c00845808 + 0 Votes Too many antivirus Chaz Chance# 1 year ago If they all want to check your computer as it comes out of sleep, they could prevent the screen updating. Also, I have had bad experiences with one of those mentioned. I would uninstall all of them and test if the problem remains, then re-install one at a time. + 0 Votes Free solutions to try WGnC 1 year ago If you're still having this issue, there are several things to consider as Microsoft has long acknowledged that both Vista and Windows 7 have compatibility problems when it comes to devices & sleep/hibernation modes. But as I can only make posts up to 75 characters, please let me know if this is still a problem for you. + 0 Votes Not AV-related WGnC 1 year ago I can almost guarantee the failure to wake from sleep mode is NOT av or anti-malware related. But MS Security Essentials is one of the most recommended security apps out there if you're looking for a good free security program. + 0 Votes Hardware-related WGnC 1 year ago I'm still firmly of the opinion it's hardware-related; for example, your motherboard/BIOS/host adapter(s) version doesn't support S3 & so won't wake peripherals. + 0 Votes So what does Dell Suggest for your computer? OH Smeg 1 year ago That is what I suggested you do above go to your Computers Makers Web Site and see if they have a solution. You could also try updating drivers for your system not just looking at BIOS Updates. Windows Security Essentials is the new name for Windows Defender if you like it is the only Microsoft provided Anti Virus Product as Defender no longer exists or is possible to update. As for what SP3 means It's Service Pack 3 but I'm not really sure what that is in relation to as there is no SP3 for Vista. Though Adobe Reader for Vista and 7 is the same so that shouldn't make any difference. As for Diagnostic Tools The Ultimate Boot CD is the best out there and it's available free here http://www.ultimatebootcd .com/download.html remember to remove the space from between the ultimatebootcd and the .com for a working link. I you do not the above will not work and if I do not insert the space the post gets deleted as possible spam. Only thing to watch with the Ultimate Boot CD is that you actually get the ISO which is about half way down the page if you are asked to pay for anything you have clicked on an Add on the page and it's not the Ultimate Boot CD. Col + 0 Votes S3 WGnC 1 year ago S3, aka Stanby, is a hybrid "deeper" sleep mode (vs. S1, for instance), whereby the system appears off, CPU has no power, lower power mode. BTW, How are you waking your PC from sleep mode? + 0 Votes What happens in safe mode? WGnC 1 year ago What happens to your monitor when you: 1) Reboot 2) Press F8 at system startup (you should hear a "beep", then begin hitting F8 key several times until you are in "safe mode" Does your monitor wake from sleep in these instances? If it doesn't, you've helped narrow the possibilities. + 0 Votes Sleep vs. hybernation WGnC 1 year ago Fyi, hybernate is ususually only an option available for laptops, but it depends on your video card. On desktops, a "hybrid" state is set by system default (just means a deeper sleep state). Speaking of video cards, be sure its driver has the latest update available. Do you recall if the monitor issue began occuring after a Windows or third-party driver update (example, network adapter, mouse &/or keyboard, USB, etc.)?
