Samsung notebook model NT90553G keyboard suddenly stopped working.Was working fine and then i used wet cotton swab to wipe it. Mistake was doing this while computer on startup page where you enter password. After that computer went psycho, entering weird words into the password box then erasing, then just flashing repeatedly. Touchpad didn't work then either but then when restarted it worked, but keyboard didn't, not even Fn keys. So left it for the night and rebooted it, tried uninstalling keyboard in device manager and restarting, still doesn't work. (Computer makes loud whirring sound and gets hot faster now.) Help?
Try connected an external USB keyboard and check if it works normally. If it does, I would suggest you to dry your laptop’s keyboard with a cool air blower.
If this doesn’t fix the problem, and the internal keyboard doesn’t work or the laptop keeps getting unusually hot, you must take your laptop to an authorized service center immediately to avoid any major defects that may arise in it over time.
