Lenovo service technicians are authorized to connect or disconnect power to the dc
power supply. See the documentation that comes with each dc power supply.

access to the full Configuration/Setup Utility menu. You can use any combination of
up to seven characters (A–Z, a–z, and 0–9) for the password.

position of the clear CMOS jumper. See “Resetting passwords” for additional
information.
