windows 7 - Laptop screen doesn't come back on after opening lid

The problem I am having is that when I close the lid on my laptop just to put the computer down for a minute and then open it back up the screen is just black, the backlighting comes on, but it's like the display isn't being sent. The computer didn't go to sleep or hibernate or anything.
After reading around a bit I found a dumb fix to get it back on (changing display with Win + P keys, and then it will come back then do it again to change it back to normal.)
I would really like it to just work properly, it used to only happen occasionally, but not every single time I close the lid and open it the screen never comes back until I do that shortcut trick, or press power button to go to sleep then wake it back up and the screen comes right back. Any suggestions are appreciated, thanks.

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!

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.

I have a similar problem when I put my laptop in sleep mode and close the lid.
Typically I open it, which boots it with a blank screen, then sleep it again (with the lid open). If I then boot it again it will give me my login screen.
Possibly you could try to use your function key (Fn) or Windows logo + P to make it switch screens to get to your desktop.
Off course these are rather "hacky" ways and are merely based on trial and error. Hopefully I can find something more conclusive like changing settings, do you need the screen to go blank when you close the lid?

Windows 7 defaults to going to sleep when closing the lid and the hibernating after a set amount of time. Pressing the power button is the only way to wake it up (press it once, don't hold it down). Under the power settings you can change Windows to only turn off the screen when closing the lid.

Many times the cause of not waking from sleep is the fault of either a video driver or chipset driver. I'd look and see if the manufacturers of those parts have newer drivers out (don't bother looking at HP's site, they usually have older drivers).

I had this issue with Vista (seems to work correctly with Windows 7). With Vista, I had to turn off wifi first, then hibernation would work correctly. When I'd forget to turn off wifi it was hit or miss (almost always a miss).

Is the lid button getting stuck? Usually it's just a little pin that gets pressed in when you close it; try pressing it yourself and see if it pops out freely. As long as the Power Options are all set to "just turn off monitor", I'd lean toward a hardware issue before an OS problem.

If you have added RAM which works though is not certified for the laptop from HP, it will cause this issue. Take out all add-on RAM and try putting the system to sleep and waking back up.
