Troubleshooting Your Computer: Dell Latitude CP
the following procedure.
1. Turn off the computer and peripherals, and disconnect them from AC power. Disconnect
any attached peripherals from the computer.
2. Make sure that the AC adapter is connected to the computer and to AC power, or
confirm that a fully charged battery is properly seated in its compartment.
3. Turn on the computer. Is the display on?
Allow one minute for the computer to initialize its components before checking for signs
of power.
Yes. The entire computer is receiving power; the problem is resolved.
No. Adjust the brightness of the display. If the Display still does not show an image,
continue to step 4.
4. Turn off the computer, and reseat (remove and reinstall) any installed memory modules.
To remove a memory module, carefully spread apart the inner metal tabs of the memory
module socket just far enough for the memory module to disengage from the socket (the
module should pop up slightly). Then lift the memory module away from the socket.
To reinstall a memory module, align the memory module's edge connector with the slot
in the center of the memory module socket. Press the memory module's edge connector
firmly into the socket. Pivot The memory module down until it clicks into place. If you do
not hear a sharp click, remove the memory module and reinstall it.
NOTE: Memory modules are keyed, or designed, to fit into their sockets in only one
direction. The sockets on the system board are notched so that the memory module
can be firmly seated only one way.
5. Turn on the computer. Is the display on?
Yes. The entire computer is receiving power; the problem is resolved.
No. The display may be defective. See
Troubleshooting the Built-In Display. If the
display still does not work, connect an external monitor and run the Dell Diagnostics.
(See
Running the Dell Diagnostics, for instructions.) If you cannot isolate the problem
after running the diagnostics, call Dell for technical assistance. (See
Getting Help, for
instructions.)
