Hi does anyone knows how to change/reset the bios password? I've tried unsetting the small battery on the back for 10 minutes but is not working...i have a hp laptop, can anyone help me..

Hiya,

You have not stated the make and model of your Laptop.

Its very simple, JUst take out the CMOS Battery wait for 5 seconds and keep it in its original place

NOTE : Take the Battery carefully from motherboard without any Scratching
