Can you look in the manual to see if there is a procedure for resetting the BIOS or CMOS to "Factory Defaults".
You could try (after power off and disconnect from charger) removing the battery (both main, and the coin), leaving for a while, then try restarting.
If you need keyboard input to change bios settings, your keyboard socket is broken, and you've just broken usb keyboard access - well congratulations, you may have bricked your device if you can't reset cmos without keyboard input.
Good luck.
