Recently I cleaned my laptop then it happened, the screen is running but blank and laptop functions properly on external display. I think it's due to BIOS corruption as I saw the Caps Lock key blinking twice, I am unable to access BIOS and also there is no Firmware option available in the Device Manager. Please help as I've tried almost everything and it's been three days.
