bios password

post #1 of 24
Thread Starter 
Client brought me a computer that someone set the BIOS password and forgot it. the CMOS chip is soldered to the board so i can't reset it that way. Is my only option to format? or will that even work?

May not work for every board, but take the cmos clear jumper, set it to clear, heck pull the watch battery off (different times for different boards), let it cook (sit), and that 'may' take care of it... Beyond that, check with the mobo manufacturer, and/or bios revision and see what they have to say on it. Formatting strikes me as pretty useless if you cannot get past post.

A lot of systems will have a backdoor password. Look in the manual.

Normally resetting a BIOS/Clearing CMOS will set everything back to default letting you do what you need to.

Wouldn't this defeat the purpose of a BIOS password?
Someone could go to the back of my computer, hit the clear CMOS button, and boot into windows bypassing the password I set.

Nfinity says: On most Toshiba laptops there will be 2 pins/solder joints underneath either the wifi card, near, or underneath the RAM. Usually they are labeled J1, J2, J5, J7, J9, JP1, G1 or CMOS CLR1. It depends on the model and that is not a complete list. Take a paper clip and short these for 15 seconds. The password should be cleared on the next boot. If the computer doesn't boot the first time, hold down the power until it turns off, then turn it on again. It's part of the process on some models.

Also, on the L455's I'm pretty sure the jumper is one of the following: J5, JP1, or CMOS CLR1.
