Turn off the laptop.
Locate & remove the coin-shaped CMOS battery, leave it out for 20 minutes, then put it back.
The BIOS is now reset to it's factory defaults.

Oh it's a tablet, you didn't say "tablet" in your first post.
No. What I said applies only to laptops and desktops.
I can't help you if it's a laptop.
Take it in to a game shop which repairs tablets. "Grainger Games" shops repair them.
