6. Replace the jumper.
7. Replace the access panel.

passwords and disables the password features.
10. Establish the new passwords in Computer Setup. See
Computer Setup (F10) Utility on page 93 for
information.
Changing a setup or power-on password
To change the power-on or setup password, complete the following steps:
1. Turn on or restart the computer.
To change the setup password, go to step 2.
To change the power-on password, go to step 3.
2. To change 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
shown:
current password/new password/new password
NOTE: Type the new password carefully since the characters do not appear on the screen.
4. Press Enter.
The new password will take effect the next time the computer is restarted.
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.
