Deleting a Setup or Power-On password
To delete the power-on or setup password, complete the following steps:
1. Turn on or restart the computer.
To delete the Setup password, go to step 2.
To delete the Power-on password, go to step 3.
2. To delete the Setup password, as soon as the computer turns on:
- Press the Esc key while “Press the ESC key for Startup Menu” message is displayed.
- Press the F10 key to enter Computer Setup.
3. When the key icon appears, type your current password, a slash (/) or alternate delimiter character,
your new password, another slash (/) or alternate delimiter character, and your new password again as

4. Press Enter.
Clearing and resetting the CMOS
The computer’s configuration memory (CMOS) stores information about the computer’s configuration.
The CMOS button resets CMOS but does not clear the power-on and setup passwords.
Clearing CMOS will clear the Active Management Technology (AMT) settings in the Management Engine BIOS
Extension (MEBx), including the password. The password will default to “admin” and will need to be reset.
The AMT settings will also need to be reset. To access the MEBx, press Ctrl+P during POST.
1. Turn off the computer and any external devices, and disconnect the power cord from the power outlet.
2. Disconnect the keyboard, monitor, and any other external equipment connected to the computer.
WARNING! To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to
disconnect the power cord from the wall outlet, and allow the internal system components to cool
before touching.
CAUTION: When the computer is plugged in, the power supply always has voltage applied to the
system board even when the unit is turned off. Failure to disconnect the power cord can result in
damage to the system.
Static electricity can damage the electronic components of the computer or optional equipment. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object. See the Safety & Regulatory Information guide for more information.
