Moin Franz,
Die Antwort findest du im Hardware Maintenance Manual für dein Gerät:
Chapter 6. Using the Setup Utility
The Setup Utility program is used to view and change the configuration settings of your computer, regardless
of which operating system you are using. However, the operating-system settings might override any similar
settings in the Setup Utility program.
Starting the Setup Utility program
To start the Setup Utility program, do the following:
1. If your computer is turned on when you start this procedure, shut down the operating system and
turn off the computer.
2. Press and hold the F1 key then turn on the computer. When you hear multiple beeps, release the F1 key.
Notes:
a. If you are using a USB keyboard and the Setup Utility program does not display using this method,
repeatedly press and release the F1 key rather than leaving it pressed when turning on the computer.
b. If a user password or an administrator password has been set, the Setup Utility program menu is not
displayed until you type your password. For more information, see “Using passwords” on page 41.
The Setup Utility program might start automatically when POST detects that hardware has been removed or
new hardware has been installed in your computer.
