Thanks in advance for any help you can give me on this. My friend spilled a small amount of water on their Dell Inspiron Windows 7 laptop. They immediately turned it off and left it upside down to dry. When booting it again after a couple of days, the 'p' key is stuck and repeatedly presses, making loging on impossible. Some of the other keys don't seem to be working, when I hit caps, num, no lights are shown- so I'm pretty sure the water has shorted the keyboard out. I have an external keyboard that they can use, but need to disable the keyboard to stop the p continually being pressed and I don't know how to do that without logging in first- which I am unable to do as the p is constantly. I'm no expert, and want to avoid disconnecting the ribbon, but will do it if that's the only solution - just try to be as basic as poss for someone who has never taken apart a laptop before!
I have tried:
Removing the key and cleaning
Pressing the key and surrounding keys firmly for 10 secs
Opening Bios and looking for a way of disabling the keyboard
Any help will be very gratefully received!!
