Dell Latitude 5420/E5420/E5420m
Owner's Manual
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 the 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.
4. 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.
