How do you reset a Toshiba laptop BIOS password?
I have a password on a Toshiba 4000cds laptop which is now forgotten and as a result can't booth my computer. The password is unfortunately laccated in the BIOS therefore does not allow me access to make any changes. However I have also done quite a few things to solve this problem but to no avail. I have tried removing cmos battery, short the system and much more. Please help.
