HP M9517C will not "wake up" from sleep

[Julilarissa]

My desktop has been updated from Windows Vista to Windows 7 several months ago.  It has only been that last two weeks that my computer will go into sleep mode and not wake up.  At first, it would only do this randomly but now every time my computer goes to sleep it refuses to wake up and I have to hold the power button down to turn it off and reboot.  Also, it seem to be rebooting slowly and when it is up and running it is much slower than before in opening up programs.  I see that others have similar issues but I didn't see and clear solutions to this happening recently.  Thanks for any input.

If your computer will not wake, and you have to press the power button this could be an option. 

The issue is that the system is going into hibernation after it has been asleep for a certain amount of time.

This guide will walk you thru how to disable this setting.

1.  Click on start

2.  Type "power" in the search field

3.  Select "Power Options" from the results

4.  Select "Change Plan Settings"

5.  Select "Change Advanced Power Settings"

6.  Expand "Sleep" then expand "Allow hybrid sleep".  If Hybrid sleep is on, then the system will hibernate after it is asleep and will only wake by pressing the power button. Make sure you select off on Hybrid

Thanks for your reply....I did check the power options and both the hibernate and "allow hybrid sleep" options are already turned off.

Also, I am running Norton Internet Security 2011 could this problem be associated with Norton?  It did recently update and I am wondering if some setting needs to be changed.

On a personal note, I've never been a fan of sleep or hibernate modes on desktops because of the inherent power settings and the HDD sizes on desktops. Notebooks have never been a problem for me, but I seem to run into the problem ofeten with desktops. I never use the sleep mode onthem because it, for all intents and purposes, acts like a stalling engine sometimes. There isn't enough enough juice getting to the necessary components and it goes comatose. It works fine on notebooks and monitors, but not so much on desktops it seems. I would say turn off the feature.
