Dell Precision M4300 - bios Locked ? ? ?
I have a Dell Precision M4300, and the HD started giving me issues, so I decided the replace the ATA HDD with a spare SSD I had lying around. When I went into the BIOS to change it from IDE to ACHI, (tried to boot with it, but SSD not seen), I found that all the darn settings were locked with security password. I have no idea if it’s using default Dell passwords or the previous owner set it, BTW, no chance of contacting previous owner. I tried both Password and Admin and neither of them worked, I know those are couple pwd’s Dell uses.
I thought I could treat it like desktop PC, so I removed the laptops battery and disconnected the CMOS battery. Came back over an hour later, and the darn BIOS is still totally locked down.
I even flashed the BIOS and updated it hoping this would give me fresh BIOS that wasn’t locked down, but it’s still locked. Not sure what’s going on, but I'm not used to BIOS saving its settings after all battery power has been removed, or the BIOS has been updated.
Any way of unlocking the BIOS settings?
