System Setup

Overview

Use system setup as follows:

•To change the system configuration information after you add, change, or remove any hardware in your computer

•To set or change a user-selectable option such as the user password

•To read the current amount of memory or set the type of hard drive installed

Before you use system setup, it is recommended that you write down the system setup screen information for future reference.

NOTICE: Do not change the settings in system setup unless you are an expert computer user. Certain changes can cause your computer to work incorrectly.

Entering System Setup

1.Turn on (or restart) your computer.

2.When the DELL logo appears, press <F2> immediately.

NOTE: Keyboard failure may result when a key on the keyboard is held down for extended periods of time. To avoid possible keyboard failure, press and release <F2> in even intervals until the system setup screen appears.

If you wait too long and the operating system logo appears, continue to wait until you see the Microsoft® Windows® desktop, then shut down your computer and try again.

System Setup Screens

The system setup screen displays current or changeable configuration information for your computer. Information on the screen is divided into three areas: the options list, the active options field, and key functions.

Options List — This field appears on the left side of the system setup window. The field is a scrollable list containing features that define the configuration of your computer, including installed hardware, power conservation, and security features.

Scroll up and down the list with the up- and down- arrow keys. As an option is highlighted, the Options Field displays more information about that option and the option's current and available settings.

Options Field — This field appears on the right side of the system setup window and contains information about each option listed in the Options List. In this field you can view information about your computer and make changes to your current settings.

Press the left- and right-arrow keys to highlight an option. Press <Enter> to make that selection active and return to the Options List.

NOTE: Not all settings listed in the Options Field are changeable.

Key Functions — This field appears below the Options Field and lists keys and their functions within the active system setup field.
