Dell Inspiron 7000 - Manual (Page 56)

1. Save any open files.
2. Shut down your computer and peripherals and unplug them from the electrical outlets.
3. Remove any
installed batteries .
4. Ground yourself by touching a metal I/O connector on the back of the computer.
5. Turn the computer over, and
remove the memory module cover .
Slide the memory module cover as far as it will go in the direction of the arrow and then lift it away from the computer.
6. If you are replacing one or more memory modules, remove the memory module(s).
Using your fingernails, 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.
7. Install the new memory module(s).
Align the notch in the 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 module
down until it clicks.
8. Replace the memory module cover.
9. Reinstall any batteries you removed in step 3, and reconnect your computer and peripherals to electrical outlets. Turn on the peripherals and then turn on the
computer.
As the computer boots, it detects the additional memory and automatically updates the system configuration information.
10. Confirm that the system configuration information reflects the newly installed memory by checking the System Memory option on the Main Menu of the
system Setup program.
To enter the system Setup program, press while the computer is booting. The Main Menu appears. If the System Memory total is incorrect, the memory modules may not be
installed properly. Repeat steps 1 through 10 until the memory total is correct.
11. Run the RAM test group in the Dell Diagnostics to confirm that the installed memory modules are operating correctly.
For instructions on running the RAM test group in the Dell Diagnostics, see Chapter 4, "Running the Dell Diagnostics," in your Reference and Troubleshooting Guide.
12. If you added additional memory to your computer, you need to delete and recreate the save-to-disk suspend file on your hard-disk drive so that it is large
enough to accommodate the new memory. For instructions, see "Save-to-Disk Suspend File" in your online User’s Guide .

NOTICE: To prevent damage to the computer, do not use tools to spread the inner metal tabs of the socket when you are installing or removing
a memory module.
NOTE: If there is 1 memory module already installed and you are adding a second memory module, the second module should be put in the
available slot. Removing existing module(s) is necessary only if they are being replaced. Depending on how you ordered your computer, there
may be 1, 2, or no modules already installed.
