Entering The System Setup Program; Keyboard Numlock; Report Keyboard Errors; Auto Power On - Dell OptiPlex E1 Reference And Installation Manual

To clear this field and allow future intrusions to be detected, enter the System Setup
program, as described in "Entering the System Setup Program" found earlier this
chapter. At the Chassis Intrusion category, use the left- or right-arrow key to choose
Reset. Then press <Alt><B> to save the change and reboot the system.
NOTE: When enabled, the setup password is required in order to reset the Chassis
Intrusion category from Detected to Not Detected. You cannot reset the Chassis
Intrusion category without a password.
Keyboard NumLock determines whether your system boots with the Num Lock mode
activated on 101- or 102-key keyboards (it does not apply to 84-key keyboards).
When Num Lock mode is activated, the rightmost bank of keys on your keyboard pro-
vides the mathematical and numeric functions shown at the tops of the keys. When
Num Lock mode is turned off, these keys provide cursor-control functions according to
the label on the bottom of each key.
Report Keyboard Errors enables or disables reporting of keyboard errors during the
POST, which is a series of tests that the system performs on the hardware each time
you turn on the system or press the reset button.
This category is useful when applied to self-starting servers or host systems that
have no permanently attached keyboard. In these situations, selecting Do Not Report
suppresses all error messages relating to the keyboard or to the keyboard con-
troller during POST. This option does not affect the operation of the keyboard
itself if a keyboard is attached to the computer.
Auto Power On allows you to set the time and days of the week to turn on the com-
puter system automatically. You can set Auto Power On to turn on the system either
every day or every Monday through Friday.
NOTE: This feature does not work if you turn off your system using a power strip or
surge protector.
Time is kept in a 24-hour format ( hours : minutes ). To change the start-up time, press
the right-arrow key to increase the number in the highlighted field or press the left-
arrow key to decrease the number. If you prefer, you can type numbers in both fields.
The default for Auto Power On is Disabled.
Wakeup On LAN determines whether the Wakeup On LAN feature is set to On or Off.
You must reboot your system before a change takes effect.
