I just acquirred a Compaq/Hp laptop model nc8230, This was bought on Ebay in the USA and posted to me in the UK. This was bought with other laptops and all was fine except this one has a bios password. I think it is one of the newer type bios security because unplugging the bios battery for hours on end doesn't get rid of the power-on bios password. As soon as you switch it on, you get a blue box with the legend "Embedded Password Security" with the picture of a key. You get 3 tries to get it right before you have to power down, the power-on again to have another go. There has to be a backdoor password here, but I can't guess it. I am desperated to get this machine running . Can anybody out there help?
