Overview

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: Unless you are an expert computer user, do not change the settings for this program. Certain changes can make your computer work incorrectly.

Entering System Setup

  1. Turn on (or restart) your computer.

  2. When the blue DELL™ logo is displayed, you must watch for the F2 prompt to appear.

  3. Once this F2 prompt appears, press <F2> immediately.

NOTE: The F2 prompt indicates that the keyboard has initialized. This prompt can appear very quickly, so you must watch for it to display, and then press <F2>. If you press <F2> before you are prompted, this keystroke will be lost.
  1. 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 (see Turning Off Your Computer) and try again.

System Setup Screen

The system setup screen displays current or changeable configuration information for your computer. Information on the screen is divided into four areas: the menu at the top, the main window, the Item Help field on the right, and key functions listed on the bottom.

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 by using the up- and down- arrow keys. As an option is highlighted, the Option Field displays more information about that option and the option's current and available settings.

Option Field — This field contains information about each option. In this field you can view your current settings and make changes to your settings.

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

 

 

 

 

 

 

 

 

 

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