Hello I have a Lenovo ThinkBook 15 G2 ITL with a BIOS password that I don't know, what is the procedure of by-passing it?
On the system board, look for the password reset jumper (PSWD). Remove the password jumper-pins' jumper plug. To clear the password, power on without the jumper plug. Wait until the desktop appears before shutting down the computer and reinstalling the jumper plug in its original spot.
