Certain changes can make your computer work incorrectly. NOTE: Before you change system setup, it is recommended that you note the system-setup screen information for future reference. Entering System Setup 1 Turn on (or restart) your computer. 2 During POST, when the Alienware 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 7.
