sometimes keyboard stops responding after XP resumes

Has anyone else noticed this odd problem where sometimes after resuming from sleep, the keyboard and trackpad become completely unresponsive?

I can still log in through fingerprint or if I plug in a USB mouse, the mouse cursor responds. It's just the trackpad/keyboard that do not work at all. If I close the lid to enter sleep mode again and then resume, the keyboard/trackpad works again.

In a similar fashion, on resume of XP, the sound completely disappeared. It only came back after I put it to sleep and then resumed. But this has only happened once (so far).

These components cannot be put to sleep to save power consumption, the problem you're experiencing is most likely due to some buggy behavior from drivers.

Thanks, I'll give that a shot. Hopefully that should solve it!
