I have a Windows 7 Professional ProBook 4440s with a 64-bit Operating System.
Last night, I tripped on my computer and became violently ill on its bottom; the computer was closed, but overturned. As far as I can tell, nothing got into the battery or keyboard, but some did get into one of the USB ports.
Initially, I turned on my computer, and was able to scan my finger (for the password) but was unable to move the cursor or use the keyboard.
As suggested, I shut off my computer, removed the battery, held down the power button for 30 seconds, plugged my computer back in, and powered it back up. I still could not use the touchpad or type, although I was still able to log into my computer via finger-scanner.
I then plugged in an external mouse, and it seemed to work, but it stops working after a few minutes. I have to keep disconnecting and reconnecting it to use the external mouse. With the external mouse plugged in, I am able to type.
What is the least-intrusive way that I can regain control of my fingerpad and keyboard?
