Dell Chromebook 3100 Screen Replacement

简介

In this guide I will show you how to replace the screen on a Dell 3100 Chromebook. I set this as moderate difficulty due to the strong adhesive under the screen cover. It can be tricky to remove the cover without a heat gun or blow dryer to weaken the adhesive. It's not impossible, but use caution to not damage the cover.

Loosen the 9 screws from the bottom cover with the Phillips #1 screwdriver. NOTE: You don't need to fully remove the screws. They will remain attached to the cover.
Once all of the screws are loose, use the opening tool to pry the cover from the frame. NOTE: I like to start near the hinges as shown in the pictures. There is a gap that allows for enough leverage to open the cover.
Locate the ribbon connecting the battery to the main board. Firmly grip the attached fabric and pull away from the main board.

Open the Chromebook and remove the black plastic covers over the screws. They are attached with a light coating of glue. I found that tweezers work best to get under the cover.
With the small covers removed, unscrew the four (4) screws holding the screen cover in place.
Using an opening tool, begin working on the sides of the screen cover to release the clips.
IMPORTANT: There is a stronger adhesive applied to the bottom part of the screen (Shown in image three under the "Dell" logo). If you have a blow dryer or heat gun, you can soften the adhesive for easier removal. Otherwise, you will need to work with a Jimmy to detach the cover.

Remove the adhesive cover to expose the connector.
Look for the latch that holds the connector in place. It will be marked with black and needs to be lifted to remove the connector. (Shown in the second image with the red arrow.)
Grip the wires and gently pull to disconnect the wires from the screen.
