I have a weird issue with my keyboard after resuming from S3 sleep: I can type perfectly for maybe 5 seconds, but afterwards the keyboard ceases to work until I hibernate or restart (or sleep again -- see below.) The rest of my system runs just fine -- just the keyboard apparently "freezes" up.
Some closer observations:
- The keyboard will work for 5 seconds (and freeze again) every time I resume from sleep, even if it was frozen from a previous sleep
- The caps lock light will work fine within the 5 seconds. But after the keyboard "freezes", the light will remain on, but I'll be unable to turn it off. Perhaps this means power wasn't cut off from the keyboard, but it's just some software freezing up the port???
Given this info, would this indicate a problem with Windows itself? Drivers, maybe? Can I rule out the BIOS as the culprit? Finally, any ideas on how to fix? Thanks!
