Hello,
I put a bios password and now I want to reset it. How I can do that?

You can remove the BIOS password from Toshiba Satellite PRO A300 by shorting the Jumber XXXB500, which is located unbder the Memory(RAM). These are actually small dots , so do not expect to see a big jumper. You need to shorten the 2 dots with each other firmaly. I sold the 2 dots with each other as it was not possible by shorting them with screw driver.
Once you short them, switch on the laptop. Enjoy . It will work...

Doesn't need to desolder again??

Thanks a lot. It worked

Hi I'm having this problem with my laptop. I not able to shorten it . Did you use a soldering iron then sold those two jumpers together to get it to work

I have been given a laptop a300 with the jumpers already soldered but it still asks for a password for the bios? Please helpo

Thanks! Worked perfectly! I managed to do it OK using a flat head screw driver to make the join...
