I got a 4540S Probook,
there is two users in the BIOS that need to swipe (fingerprint sensor) or type a password to login, i wanted to disable that or change the password, as the password was not working and only the swipe was.
i downloaded biosconfigutility.exe and changed the admin password to 123456789 in order to activate it, now its saying even the admin password is wrong (i might , a very slight chance, have mis-typed the password for the admin.
i was wondering if removing the battery and the cmos battery for few hours would fix the problem, cause i noticed they selling new chips in ebay that are programmed with a default password, so i assumed the cmos trick wouldn't work anymore.
Thank you !!
