Laptop wont wake up after closing the lid - A Solution

I had this problem and so have tons of other people looking for a way to fix it. You close your laptop lid only to discover - sometimes.. not all the time, the PC will not wake up from sleep. Hitting buttons, moving the mouse, nothing works. You wind up hard booting the system to get back in.

My solution involved checking that Sleep mode under Power Options was actually activated to begin with. People don't want the PC going blank on them so they set all options to Do Nothing under "Change what happens when I close the lid". This is the wrong thing to do. I had everything set to Do Nothing. What should have been checked was Sleep. This will put the PC into sleep mode and you can wake it up by moving the mouse.

However we don't want it to work this way. We want to close the lid and have the PC not go into sleep mode at all. Even if under "Choose when to turn off the display" and "Change when the computer sleeps" and all your power plan settings are set to "Never", some PC's will still give you a black screen when you close the lid as if your going into sleep mode. As if something is clearly not working. It's not really going into sleep mode. It's fooling you. It's wonky. I have been unable to determine the cause of this but if actually activating sleep mode fixes the problem, then so be it. The next step will be to get out your shotgun and blast the sucker - nobody wants that.

Because this sleep mode did sometimes work under "Change what happens when I close the lid" with all settings set to Do Nothing, it seems that the bios or some hardware based function is controlling what happens when you close the lid. Choosing to activate the sleep option from Windows seems to override that function. I could be wrong about what is actually happening here, I'm just going on appearances. I'd rather my display never darkens at all even with the lid closed but I'll take this fix for now.

I've tried that. It doesn't seem to matter if Fast Startup is on or off, the only thing that effects this seems to be to make sure sleep is activated. I have read reports of this problem happening with many models of HP and Dell laptops. This one is a HP Pavilion G7 model. I have an older Compaq Presario that works perfectly ( windows 7) I can close the lid and the display never dims.
