Losing or forgetting the BIOS administrator password on your Lenovo ThinkCentre M720q Tiny desktop can prevent you from changing hardware settings, updating firmware, or modifying boot priorities. Since this password is saved directly onto a non-volatile chip on the motherboard, simply removing the CMOS battery will not reset it.

Unlike the desktop PCs of a bygone era, where resetting the BIOS password often involved a simple jumper swap or removing a CMOS battery for a few seconds, the ThinkCentre M720q represents a new generation of security. Its architecture is designed to resist exactly these kinds of physical attacks. The traditional methods are largely ineffective. The CMOS battery, while present, is often deeply integrated, and removing it may clear custom settings but will not erase the master password hash stored in non-volatile memory. Similarly, a dedicated "clear CMOS" jumper is often absent or, when present, only resets configuration defaults, not the administrator or system passwords. This design choice is intentional: in a corporate setting, a lost password should not equate to a lost computer, but nor should it be trivial for a thief to bypass.
