I have a Toshiba Satellite C655D-S5300 laptop that worked fine previously, but has been stored for a few months. I never set a BIOS password for it, but when I took it out a couple of days ago, it would not boot at all without one. It doesn't make sense, but it seems something must have reset itself while sitting on the shelf. After I enter three incorrect passwords, it just shuts down. When I first turn it on, it briefly displays a logo for Insyde, so I assume that is the BIOS. There is also a message saying to press F2 to go to the setup utility or F12 for the boot manager, but pressing either of those keys will not get me by the password. I am not specifically trying to get into the BIOS. I only want the computer to be able to boot, which it will not, without me first supplying a password I do not have and have never needed in the past. I tried booting from a DVD, which doesn't work either. I can hear the drive spinning, so I think booting from a DVD must be enabled, but I am still stuck on a screen requesting a password. I have searched everywhere online without finding anything that works. The Toshiba support site is of no help either, and actually provides a link to Tom's Hardware for support. I am at the point where I am ready to disassemble the machine if I thought that would solve the problem. I have nothing to lose. Thanks for any help you can provide, even if it is only guidance showing me where else I might look for a possible solution.
