I need to reset the BIOS password of an Acer Aspire One NAV50 netbook. I know that the password is stored in CMOS and I need to invalidate its settings. I want to know if software compatible with Windows 7 exists to reset the password for me (I can still login to Windows 7 as an administrator) because I don't want to fidgit with opening motherboards and the like.
CmosPwd can grab the password from quite a large number of BIOSes. If it works on yours, you can get the password and use it to get into the BIOS, then reset from in there. It does not do any harm to try, since it's just for reading the password, not changing/writing/resetting it.
Alternatively, a BIOS flash might work. I'm unsure, and it could just brick your computer, so better to wait for someone else to answer if CmosPwd does not work.
There's a tool called CMOS De-Animator that runs even under 64-bit systems. If that won't work, there's an integrated make-bootable wizard in it, which has some functionality to decipher certain Acer laptops.
You need to take care though: as the author says, certain BIOS revisions check for unauthorized CMOS port I/O and lock themselves up upon next re-boot.
The password can also be stored in a separate EEPROM, away from the actual CMOS data.
