Windows (7 & Vista) laptop monitor does not come back after closing lid

Question

I'm experiencing an issue with Windows Vista (and now Windows 7) with my laptop. When I close the laptop lid the monitor goes blank but will not come back on after I re-open the laptop. The screen stays blank and nothing that I do will get it to come back. The laptop is an HP DV9000 series.

Has anyone else ran into this issue? One of the solutions I've seen online is to go into the device manager and replace the lid driver with something nonsensical (the website suggested pointing the driver at the sound recorder). This does solve the problem by disabling the lid but doesn't really resolve the root issue.

I'm asking if anyone has any method I can use to debug what's going on. How do I tell if it is an operating system issue vs. a malfunction within the lid itself. I'd actually like the lid to function as it's meant to.

Thank you!

Solution 1

You might also want to see if there is a BIOS update for your notebook. Things like what you describe can sometimes be caused by ACPI (i.e. power management) oddities that can be (and often are) fixed in BIOS.

Solution 2

I had the same problem when i did a clean install of windows ecently.

All i had to do was call task manager alt+ctrl+del and the screen came back.

The problem dissapeared after i did another clean install of windos 7

I would like it to go blank for power/heat saving purposes. Thank you !

@Luminose: Unfortunately I've changed the power settings to not sleep on lid close and only turn off monitor. When I re-open the laptop I can tap keys etc. and hear the default beeping in the background indicating I'm hitting something, just no picture. Thanks for the reply !

@Giovanni Galbo: So you had to run without wifi if you wanted to use the lid? (or had to turn off wifi every time before you closed the laptop?). Oddly enough I recall the lid functionality working fine until I installed either the MS Office Suite or Visual Studio 2008. I suppose I could try uninstalling these and trying again. Thanks for the reply !

I think my issue is a little different, now that I re-read the question. On Vista, I would have to turn off wifi before hibernating. If I didn't it would not go to sleep properly (it would be in some sort of zombie state.... fan still on, hard-drive not spinning, monitor off [similar to what you're experiencing]. It works as designed on Windows 7 (Interestingly enough, by looking at the wifi light I think Windows 7 just shuts off the wifi before sleeping and then turns it back on when waking up)

@Andrew: Nope I thought that at first but it's not stuck. I'm just leaving the lid up for now and turning on the power saving mode for the monitor. Thanks for the reply !!
