Clearing and Resetting the CMOS – Models 3300/3305
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
during POST.

Shut down the operating system properly, then turn off the computer and any external devices,
and disconnect the power cord from the power outlet.
2.
With the power cord disconnected, press the power button again to drain the system of any
residual power.
WARNING!
sure to disconnect the power cord from the wall outlet, and allow the internal system
