Responder a: How to remove bios passwordThings are not that simple. removing the CMOS battery to reset the BIOS may have worked in some old laptops. But not in any later or current model Toshiba Satellites. And looking for a jumper that is labelled 'reset'or whatever is waste time, is not a PC. And SATA lock.??.. we can just ignore that. If that was the case we could get to the BIOS, of course. Before it even looks at the HDisk. Roger Davies solution is the only one I have heard of working. He neglected to tell you though , there is a chance you can fry the board if not done correctly. His L-series does still have some MBoard labels. I believe there is an actual location ID for that short out solution on the L-series MBoard. Search on Google, you will find the solution. I have an R50 and the MBoard has no labels or location IDs. And no known solutions, that im aware of. So if anyone can tell me how to reset the BIOS lock on an Satellite R50 ? I would greatly appreciate it.
