Laptop keyboard not working (even on start up)
I have a Dell XPS laptop with a Windows 7 installation.
I turned it on this morning and the keyboard no longer works - even when attempting to go to the settings (F2) or BIOS (F12) screens it usually ignores it.
When it goes to the Windows 7 login screen, it fills up the password field - just like if a key is being held down - however, I am unable to stop it from filling up completely as no keys work (although the touchpad does work) - it even 'enters' (and brings up the 'wrong password' text box) without any input from myself at all.
Fixes I've attempted:
1. Remove the battery and charger, hold down the power button for 30 seconds (suggested elsewhere).
2. Unscrew the back of the laptop and clean the components.
Any suggestions as to how I could self-fix this without shipping it off somewhere? Thanks

Hi dg1991,
I suspect a key is stuck on the keyboard. Check for any stuck keys or any dust accumulated on the keyboard overall.
Was there any liquid spillage on the system? Was the system dropped? When did the issue start?
Try this step -> ensure the system is off -> press and hold the fn key + power button to turn it on. It should initiate the diags. If it does, let it run through the diags and make a note of any possible errors you might encounter.
To isolate a faulty keyboard -> disconnect the keyboard (cable) and turn on the system with an external keyboard attached. See if that works. Go to support site - http://dell.to/1Pwntme - enter the service tag and download the service manual to check on how to disconnect the keyboard.
If the external keyboard works fine - try a BIOS update - from the above link - select drivers and downloads and run the BIOS update - then connect the keyboard - restart and check. Sometimes a BIOS update fixes most of the issues.
Keep us updated.
