BIOS Hack – How to Reset Laptop BIOS Password!

For those of you with older Toshiba laptops, here’s a really simple loopback parallel port device you can make to reset your BIOS without opening up your laptop.  This could potentially also work on other branded laptops.

So you’ve got an old Toshiba Satellite (full list of compatible models at the bottom), turned it on and to your aggravation you are greeted with a Password prompt. While there are several ways to go about removing the password, I chose to build a very simple dongle device which connects to the parallel port – known in the trade as the Loopback Plug . When connected to the computer and the machine is started up, it will erase the contents of the BIOS back to factory defaults, taking out the password.
