How to Replace the Memory on a Dell Latitude E6400

by Lucosi Fuller

When the factory-installed memory module on the Dell Latitude E6400 laptop dies, or you just want to replace a module with another that has more memory, quickly and inexpensively install a new one to get your computer back up to speed. The only problem is finding the memory module compartment on the computer. Most laptops have base-mounted memory module compartments, which are easy to find. This one does, too, but to find it, you have to remove the base cover and then everything is out in the open.

1

Turn off the computer and disconnect the power cord. Strip the computer of any cables running to it from peripheral devices.

2

Turn the computer over and extract the screw in the middle of the base cover.

3

Slide the base cover toward the front of the computer and then lift it off to expose the memory modules, which are stacked on top of each other in the front of the computer.

4

Remove a memory module by spreading the tabs that secure it to the port and it will pop up at an angle. Pull the module out of the port.

5

Insert the new memory module into the vacated port at an angle and press it down gently until the tabs lock into it.

6

Replace the base cover and turn the computer over. Connect the peripheral devices and the power cable to the computer to finish the replacement.

Tips

  • For a computer with two memory modules installed, one of which is bad, you may have to perform this procedure twice just to ensure that you've replaced the right module. Do it once with one module and start the computer up to see if the system shows more memory. If it doesn't, do it again with the other module.
  • If you receive an error message or hear a series of beeps, your system may not recognize the new memory. Remove and reinstall the modules to ensure they are securely seated in the sockets.
  • If your system will not boot, check all of the connections inside your computer. It is easy to bump a cable and pull it out of its connector, disabling devices such as your hard drive or CD-Rom.

Warning

  • Installing RAM incorrectly will cause system-wide problems and may stop your computer from working.
