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

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:

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.
