Windows 7: Laptop Non-Responsive When Wakes Up From Sleep

I've had an HP dv5t laptop for about a year and a half (see specs), and so far (knock on wood) it's been pretty much perfect EXCEPT for one problem that has been happening on and off for the last several months. It occurs about once or twice a month for no apparent reason --- and I don't know if this this is a hardware or a software problem. What happens is that all of a sudden, for no reason my keyboard and touchpad/mouse are completely non-responsive -- and the only thing I can do is use the power button to shut down. When I reboot everything seems fine, until the next time it happens, a week or two later. It can happen when the laptop is running, but more often it happens when I open the lid after the system has been in Sleep mode. (I keep the laptop in 'Sleep' mode all the time when the lid is closed, and only fully "shut down" once in a while.) Everything seems to load properly --- the Desktop looks perfect and all my apps/icons are there, but the mouse won't move and the keyboard doesn't respond.

I'm afraid that my system is heading for a major problem and I'm trying to avoid it, if I can. I certainly don't want to have to send it in to HP for a repair --- as I've heard the horror stories. So I'm hoping that this will be a familiar problem to someone, that I can handle myself. What do you think?

Uh oh! Does the lack of response mean that I've got an unsolvable problem? Does anyone have any thoughts as to what the problem could be?

Hey Imperfect, you'll need to try out a few things to isolate the problem.

1) First, update your video drivers.

2) Run the power troubleshooter.

Open the Power troubleshooter

3) Try out the steps on MS support page for such issues.

How to troubleshoot performance issues with standby, hibernate, and resume in Windows Vista

This includes the clean boot procedure which helps identify rogue drivers.

4) If nothing works run a sfc scan.

SFC /SCANNOW Command - System File Checker

5) Try swapping with a ps2 mouse if you're using a usb one or try swapping the usb port.

Let us know so we can suggest alternatives if these dont work.
