My laptop shows blank screen With no messages when turned on. I can hear the sound of fan, I can see caps lock blinking twice and f12 showing red light. My esc key is not working so I cannot run startup for BIOS update. I tried hard reset using fn+b and fn+v, fn+f9, f10, f11 but nothing works.Can someone suggest an alternative?

Depending on the age of the PC and the BIOS vendor...

If it is BIOS related then....
Hopefully one of these documents will cover (and solve) your problem...
