gym thank u for the expalnation

Cindrella: BIOS is usually made up of CMOS chip (Complementary Metal Oxide Semi Conductor - because of its low power consumption) as long as the battery is connected BIOS can keep it self and settings alive.... as soon as the power drys up all passwords and custom settings are cleared.


This method would work on some systems and will not work on others newer system....

There is this jumper near that battery that says something like 'Master Rest' change the jumper potion to it... reboot... go into administrative mode for BIOS and get the password fixed or removed.... there are also some backdoor passwords deployed by each manufacturers... better try those before you go all cranky on system.....

NOTE:
NEVER PLAY WITH JUMPER IF YOU ARE NOT SURE WHAT YOU ARE DOING. U MAY ACCIDENTALLY SHOT-CIRCUIT YOUR MOTHERBOARD. I have learnt it the hard way :(
