My toshiba a205 s5804 is asking me a bios password

There is a known issue on this model (A205 and A215) and Toshiba knows about it. A password can be automatically be set by the computer and will need to be removed and have the BIOS updated so it won't happen again by an "authorized service provider." You can locate your closest Toshiba ASP at support.toshiba.com This is a known issue and Toshiba knows about it. You should get this covered at no charge if you take it into an ASP, make sure to verify this with the ASP and take it somewhere else if they tell you it will cost you anything. Toshiba will cover this till December 31st 2010.

The only thing you can do is completely reset the CMOS memory. This requires opening the underside access panel, locate the CMOS backup battery and disconnect it for up to one minute. The PC will then have to be reconfigured. I'd suggest having this done at the nearest Toshiba support center.
