Dell Inspiron 1420 - Vista, it is old one was working perfectly till now.
Issue: the Keys automatically starts typing and performing various keystroke functions, also disabling may keys. Even in BIOS mode key entries were restricted
Solutions tried ( nothing worked):
Disabled the keyboard , used external keyboard USB ( doesn't resolved)
bought new dell keyboard, didn't resolved the issue
Ran in safe mode, issue persist
Formatted to factory default mode, issue persist
Observation: I see multimedia keys always blinking randomly ( can this be multimedia keys, interfacing with keyboard.
I planned to remove it but it was soldered across. please confirm if I shall disable this keyboard ( hardware) as extra step, if Yes shall I remove solder or there is workaround.
Any guidance would be help if any other option to be tried
