the first tip and most recommended to bypass BIOS setup is the using of BIOS manufacturers backdoor password, this password are hard coded into the BIOS by the manufacturer and will override any other created password, this might seems little easy solution, but you must know (i) who made the BIOS, (ii) the BIOS version that has been installed  in the system (iii) what backdoor password has used for the BIOS, so for you to know the backdoor of a system your only chance is to contact the BIOS manufacturer or read the documentation that came with the system. In addition since laptop have better BIOS security than Desktop Cousing they classically not employ the use of backdoor but its worth trying, as an extra security measure, many BIOS manufacturers have added a features that will lock you out of the sytstem completely if you try to guess the password and enter it incorrectly 3 times, make sure you are entering the correct password.

Keyboard Error

another methods  you can use to get access to the BIOS setup program is to overload the keyboard buffer by holding down a key as the system boots, once the buffer has been overloaded you will receive an error message and you will be taken into the setup program where you can change the password, this method does not work on all BIOS programs but it is worh trying becuase it really cant do any damage or permanently lock you out of the system.
