Introduction

I will be showing you how to remove, and replace the WiFi card in your Dell latitude E6400. The entire process shouldn't take more than 10 minutes, as only 2 screws need to be removed to remove the card.

Simultaneously slide the battery latches (outlined by the red box) to the dock connector in the middle. This will release the battery. Just slide the battery away from the computer.

  • This will release the battery. Just slide the battery away from the computer.

  • Open up the computer and press and hold the power button for 5 seconds. This drains any power left inside the computer.

  • This is important, as if electricity remains in the notebook, it can shock you and damage the logic board.

Loosen the center screw with a philips screw driver. This is the only screw that needs to be loosened. It can't be removed as it is captive the the bottom plate.

Use a plastic opening tool or a spudger to remove the antennas. I use my fingers, but the picture shows and iPod opening tool because most adults have bigger fingers.

    • I'm 14, so my fingers are small enough.

  • Some E6400 models have a card with three connections-a gray wire in the middle-marked appropriately.

The card should instantly pop to an angle less than 45 degrees once the screw is removed. Now simply pull the card strait away from the slot.

Why is your soundcloud linked as the wifi card site. It is really not appropriate considering how great of a job you did with the instructions for this repair.
