1- Try to remove the laptop battery for more than 10 seconds. Also press the power button while the battery is out to make sure the capacitors are empty. Put back the battery in place and start it again, now see if you can access the BIOS.

2- If it still doesn't work, you could open the laptop and remove the CMOS battery on the motherboard, wait for 30 seconds with the battery out and put it back in. It should reset your BIOS to default. IMPORTANT: *** It's a lot safer to remove the laptop battery too when you need to touch the motherboard or play inside the computer ***
