Hi guys I am having an issue with my laptop. It was updated using dell drivers and apps that match the service tag and everything was working smoothly until I rebooted today and now a password is requested on the bios screen before I can go any further. I don't have a password on my OS or my bios but this Dell secure manager must have chosen a default one on my behalf. Now I can't get into anything, it won't boot to CD drive or usb it just stays on this bios password screen. I tried nearly everything I could think of. I removed the cmos battery. Tried various possible default passwords and nothing. I don't really want to try shorting the nvram chip, too much could go wrong with powering up a disassembled laptop and even then it might not work. Any help at all would really be appreciated.
