You need to reset a password-protected BIOS configuration. What do you do?
Answer / chaitanya
While BIOS itself has been superseded by UEFI, most systems still follow the same configuration for how they keep the settings in storage. Since BIOS itself is a pre-boot system, it has its own storage mechanism for its settings and preferences. In the classic scenario, simply popping out the CMOS (complementary metal-oxide-semiconductor) battery will be enough to have the memory storing these settings lose its power supply, and as a result it will lose its settings. Other times, you need to use a jumper or a physical switch on the motherboard. Still other times you need to actually remove the memory itself from the device and reprogram it in order to wipe it out. The simplest way by far however is this: if the BIOS has come from the factory with a default password enabled, try ‘password’.
