Not Exiting Sleep Mode

[Meganerd20]

So, I'm having an issue that seems to have just started today, out of nowhere, where my laptop seems to not want to exit sleep mode.

So here's how the issue goes: if the laptop is left, you know, inactive for a while, the screen goes black. I'm used to that, that's just what I guess is sleep mode, never really learned the proper term for it, I just call it sleep. Might be standby. But anyways, it's the normal thing where the screen goes black after a short period of inactivity. Normally just moving the mouse or something will make the screen come back and it's all fine.

But, just today, I'm having an issue where the screen doesn't come back. It just stays black, and I've had it happen twice so far (back to back); once where I closed the laptop, and once where I'd just left it alone for a while. In both cases when I returned to try and 'wake it up', the power button's light stops flashing and becomes solid (normal for when waking the computer up), but the screen stays black.

Now both times I've been able to get the normal display back but hard restarting, just by holding down the power button. But obviously, as it happened a second time, that offered no permanent change. And I've checked 'hybrid sleep' or whatever, and that's off. So I'm not sure what's happening, or why it started so suddenly.

I have no idea how to find out what model of Pavilion I have, short of going through the entire list. But I tried System Restore, and it seemed to have no effect.

Mostly I'm curious as to potential hardware problems.

It seemed to end up being a problem with the BIOS as I updated the driver for that and the laptop is fine now.
