Greetings,
I had the same problem. I followed up Carlos instructions and rebooted. Now, the following happened. My keyboard has stoped working. I had to use visual keyboard to be able to loging my pc. So, I went back to regedit and changed back the value to what it was (1). I rebooted and then the keyboard started working and windows started charging properly. Both of my problems are now solved.
Thanks Carlos.

Please create a restore point just in case anything goes wrong.
Open the registry (Start, Run, Regedit <ENTER>)
Go to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\
Look for the "Start" DWORD entry and change its value to 4.
Accept and exit.
Restart.
You should be Ok now.
