sure it is on line.
3. Confirm the computer’s system configuration

devices, such as ports.
For instructions, see the topic titled “Setup Program”
in the online System User’s Guide.
4. Disable all system setup options for power

want to start the Dell diagnostics so you can see the
menus on your display.
When you start the diagnostics, the Dell logo screen
appears, and a program tests the random-access memory
(RAM) that will be used by the diagnostics.
If a failure in RAM is detected, a message appears on the
screen telling you the memory address of the defective
memory module. Write down the memory address and
see Chapter 5, “Getting Help,” for instructions on obtain-
ing technical assistance.
If no errors are found in RAM, the diagnostics loads and
the Diagnostics Menu appears (see Figure 4-1). The
menu allows you to exit to the MS-DOS prompt.
