Boot Speed
Boot Speed allows you to choose between the computer's processing speed (the default) and Compatible, a slower compatibility speed. The
compatibility speed varies, depending on the configuration of your system.
When you change the setting in the Boot Speed option, the System Setup program stores and continues to display the new setting even if you do
not reboot your computer when you exit the System Setup program. If you start the System Setup program again during your current work session,
the processing speed displayed for the Boot Speed option may not match the actual speed at which your computer is running.
For a change in the Boot Speed option to take effect, you must reboot your computer.
Brightness
Brightness allows you to specify the brightness of the display when the computer is operating on battery power. Use the left- and right-arrow keys
to change the brightness of the display. When the computer is powered by a battery, the default is Minimum. If the computer is using AC power,
the default is Maximum.
A change to the Brightness option takes effect immediately (rebooting is not required).
Click Volume
Click Volume allows you to disable or adjust the volume of the keyboard clicks if the Keyboard Click option is enabled. The default is Maximum.
A change to the Click Volume option takes effect immediately (rebooting is not required).
Configure Setup
Configure Setup allows you to restrict access to the System Setup program in the same way a system password restricts access to the system.
This option is only available when you set the administrator password.
Date
Date resets the date on the computer's internal calendar.
Your computer automatically displays the day of the week corresponding to the settings in the three fields that follow (month, day-of-the-month,
and year).
A change to the Date option takes effect immediately (rebooting is not required). However, you must reboot to make the change apparent to the
operating system.
To change the date, 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 in numbers in the month and day-of-the-month fields.
