If you switch off the device during the update, the BIOS will be incomplete and corrupt. This
may result in malfunctions.
Leave the device switched on during the update.
If you have purchased a new BIOS update for your device, follow these steps to install the
update:
1. Copy the update to a USB memory stick.
2. Reset the device (warm or cold restart).
The following message appears briefly on the display at the end of the self-test:
Press ESC for boot options
3. Press <ESC> to open the BIOS selection menu.
4. Click the "BIOS Update" button.
5. Follow the instructions on the screen.
There may be several reboots after a BIOS update. These reboots are initiated by the
Management Engine (ME). The reboots are required by the ME to adapt itself to the changes
of the BIOS update.
Alarm, error and system messages
During startup (the boot process), the BIOS first performs a
ower
n
elf
est (POST) and
checks whether certain functional units of the PC are operating error-free. The boot
sequence is immediately interrupted if critical errors occur.
BIOS initializes and tests further functional units if the POST does not return any errors. In
this startup phase, the graphics controller is initialized and any error messages are output to
the screen.
The error messages output by system BIOS are listed below. For information on error
messages output by the operating system or application programs, refer to the
corresponding manuals.
