Easy job, just removed the bios password on my toshiba satellite L450d-12x, to do so remove Ram cover and Ram modules, then carefully remove label from motherboard underneath where the ram was, there is a 5mm square copper bit that if u look carefully is 2 pieces arranged into a square (it's labelled J1) u just need to short these two pieces together, I used a small flathead screwdriver but it is lacquered so I had to scratch it slightly to get a good connection. Also make sure u remove battery and charger first and hold down power button for 20 seconds to drain any excess charge. Good luck everyone!
