Over the last few weeks I've had 3 different satellites come in with a non-functioning keyboard and trackpad. Connecting a USB mouse will give you a usable mouse, but a USB keyboard will still not work. Anyone else seeing this? Seems like a weird issue I've seen frequently enough to worry about a pattern.

reset the filters within the registry. It's a problem with upgrading from 8.0 to 8.1. Find the hardware ID for the keyboard and mouse.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class{4D36E96B-E325-11CE-BFC1-08002BE10318} Edit the value UpperFilters to read kbdclass
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class{4D36E96F-E325-11CE-BFC1-08002BE10318} Edit the value UpperFilters to read mouclass
reboot and it should work on startup.
Tried this on the first one i got my hands on today, didn't help. But I'm definitely saving this info for the future.
There is a bad keyboard/mouse driver going around the mix. We have had about 10 the last month. You have to nuke the registry keys for keyboards and mice.
Actually just enabling and then disabling "Filter keys" did the trick for the 3 I saw today. (Two more came in since OP)
Lucky -_-
We've been throwing everything we had at them until we found the registry hack. Except one of them did have a bad keyboard.
