    For very personal computers, you can reset all BIOS settings (including administrator password) by simply removing the CMOS (CR2032) from the motherboard For a few seconds, and then putting everything back in place. This does not apply to Optiplex

    To be sure there is an extra option for this Dell, there is a PSWD hoodie that is usually found next to the power connector on the motherboard. After the usual removal of the jumper, BIOS security can be reset using a daily “battery routine”.
