Computer won't come back on after going to sleep mode.
When my computer goes dormant for a while andI try to wake it up, I can not. I have to make it shut off and then restart it which I know tears it up. I get a no signal message on my screen and I don't know what to do.

Re: Computer won't come back on after going to sleep...
If you computer is going into hibernation, the best thing to do is disable it. These days it is better for the pc to stay on for updates and scans. Right click on an empty area on the desktop, click properties, click screensaver, click power set turn off hard discs, standby and hibernate to never, I usualy turn monitors off after 30 min seth

Open monitor and look at power supply board for capacitors which are "balooning" or deformed in any way. These look like cylindars on the board. These tend to dry out and make what you are describing occur. Replacing them usually fixes about 80% of the problem you are describing. Those parts run about $0.25 to $0.75 each.. well worth trying, right?
You should be able to just press the main system unit power button to wake up your 'sleeping' computer which will then resume your Windows desktop and bring you back to the Login panel if you have a password set for your account.
Hey there, Normally simply pressing a random key on your keyboard or moving your mouse should wake it up, if it doesn't though I think the easiest way to solve this is to simply turn off the sleep mode after x amount of time.
If you have windows 7, press the start button and type in "power options", go ahead and open power options and there you will be able to set the time it takes before your PC shuts down, and you can also set it to never.
If you still wish to use this feature but just want to be able to it's a bit tricky and it won't even work for all PCs but if the keyboard waking isn't working, then it's probably because your pc does have this feature. When your PC is off, boot it up again and enter the bios by pressing F10 i believe it is for HP.
And somewhere you should be able to set which devices are allowed to wake up your computer, all devices are probably disabled now, so go ahead and enable the keyboard to wake up your computer. Now save and exit, and the next time your PC goes to sleep mode you should be able to wake it up by pressing a key on your keyboard.
I hope I was able to assist. If I was, please don't forget to rate this solution.
press and hold the power button down for about 5 secs. The computer will shut down. Restart it and right click on the desktop, go to properties then look for screensaver tab , then choose power options, click on hibernation tab at the top and uncheck enable hibernation. Or choose stanby options and choose a longer time before the computer goes to sleep.
If you can restart it and it starts up fine, then I would go into the power settings and disable sleep mode. Every computer is different on how to wake a sleeping computer, so you could read through your manuals and find out for yours, but I just disable sleep mode on all computers so i dont have to hassle with it.
It may be going into sleep mode. When the screen goes black, try pressing the space bar on the keyboard to wake it up. If the computer wakes back up again, then you may need to adjust your power settings. Try it and let me know what happens.
If only the monitor is going to sleep, then it could be a problem with the connection from the monitor to the computer or with the cable.
If the computer goes to sleep and if you are not able to wake it from sleep then check the sleep mode settings and also the power management settings for the keyboard and mouse.
You may also do a system restore if you are not able to wake the computer from sleep.
Yeah, im not sure about how to fix the problem with it shutting down like that, but one option is to go under your control panel and taking off the sleep function, or putting it on a 4 hour timer so that doesnt go into sleep mode anymore. However, the problem is not your monitor but your computer. Id just take the sleep mode off, there is no need to have it on.
