System Setup
Overview
Use the system setup to:
• get information about the hardware installed in your computer, such as the 
amount of RAM, the size of the hard drive, and so on
• change the system configuration information
• set or change a user-selectable option, such as the user password, type of 
hard drive installed, enabling or disabling base devices, and so on
 NOTE: Before you change system setup, it is recommended that you note the 
system-setup screen information for future reference.
Entering System Setup
1Turn on (or restart) your computer.
2During POST, when the DELL logo is displayed, watch for the F2 prompt 
to appear and then press  immediately.
 NOTE: The F2 prompt indicates that the keyboard has initialized. This prompt 
can appear very quickly, so you must watch for it, and then press . If you 
press  before the F2 prompt, this keystroke is lost. If you wait too long and 
the operating system logo appears, continue to wait until you see the 
Microsoft Windows desktop. Then, turn off your computer and try again. See 
Turn Off Your Computer and Connected Devices on page 13.
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 setup item, active help screen, and key functions.
