You cant bypass toshiba bios password. U need to bring it to Toshibas Authorized service center. I think this model if free of charge eventhough not in warranty. To make sure , call 18004577777, verify if this model is free of charge.

This should be able to be solved by opening the Ram bay and shorting out two solder points. Usually marked with a "xxx". The notebook should be started with these solder points shorted. Once the pc is on, it should go through the normal process without asking for a bios password. Once the pc is restarted, the CMOS password should disappear.

Hi there.
1. Turn the computer OFF, if it's on.
2. Remove the memory module cover, on the bottom of the computer.
3. Check the configuration of memory modules in the two sockets. It's necessary to have a memory module present in the outermost socket only.

• If there is a memory module in only the outermost socket (the one farthest from the system board), then continue to step 4.
• If there is a memory module in only the innermost socket, move it to the outermost socket.
• If there are memory modules in both sockets, remove them both, then re-insert one of them into the outermost socket.

4. Carefully peel back the black Mylar film. Pull this film to the side enough to expose the B500 solder pads. Do not remove the film completely, because it may be difficult to re-attach it correctly.
5. Short the B500 solder pads on the system board. Needle-nose pliers or a flat-blade screwdriver works well to short them.
6. While continuing to short-circuit the solder pads, turn the computer on, and continue shorting the pads until the Toshiba Logo Screen appears. then remove the short.
7. Re-position the Mylar film over the system board.
8. If you removed a memory module, turn the computer OFF, then re-insert it.
9. Re-attach the memory slot cover.
10. turn on computer, if it boot password has been removed.

Good luck and thanks for using Fixya!!
