Troubleshooting Your Computer: Dell Latitude CP
If the memory count displayed in the lower-right corner of the System Setup program is less
than the amount installed, make a copy of the Diagnostics Checklist found in
Getting Help and
fill it out as you complete the following procedure.
NOTE: Before beginning this procedure, make sure a memory module is installed in one of
the memory module sockets on the system board. The computer will not function unless there
is at least one installed memory module.
1. Reboot the computer, and open the System Setup program by pressing the <Fn><F1>
key combination. Does the memory total displayed match the actual amount of memory
installed in the computer?
Yes. The computer needed to update the memory; the memory check phase is now OK.
No. Continue to step 2.
2. Turn off the computer, and reseat (remove and reinstall) any installed memory modules
in your computer.
Loose or disconnected memory modules may cause intermittent memory problems.
removing and reinstalling, or reseating, memory modules often corrects the problem.
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 way 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.
3. Turn on your computer, and press the <Fn><F1> key combination to open the System
Setup program. Does the memory total displayed in the System setup program match
the actual amount of memory installed in the computer?
Yes. A memory module was loose; the memory check phase is now OK.
