Nx Boot Failure - Lenovo Flex System x220 Installation And Service Manual

The POST event log contains the three most recent error codes and messages that were generated
during POST.
The system-event log contains POST and system management interrupt (SMI) events and all events that
are generated by the baseboard management controller that is embedded in the integrated management
module II.
Important: If the system-error LED on the front of the compute node is lit but there are no other error
indications, clear the system-event log. Also, after you complete a repair or correct an error, clear the
system-event log to turn off the system-error LED on the front of the compute node.

• User Security
Select this choice to set, change, or clear passwords.
You can set, change, and delete a power-on password and an administrator password through this
selection. If you set a power-on password, you must type the power-on password to complete the system
startup and to have access to the Setup utility menu.
You can use any combination of up to from 6 to 20 characters (A - Z, a - z, and 0 - 9) for passwords.
Keep a record of your password in a secure place.
If you forget the power-on password, you can regain access to the compute node by using the power-on
password override switch (see "System-board switches" on page 18).
Attention: If you set an administrator password and then forget it, there is no way to change, override, or
remove it. You must replace the system board.
You can also regain access to the compute node by removing the CMOS battery and then reinstalling it
(see "Removing the CMOS battery" on page 650 and "Installing the CMOS battery" on page 651).
Important: Removing the CMOS battery clears the settings in CMOS memory.
