How to Replace the Screen in an HP Business Laptop

It’s easy to break the fragile screens found in laptops. Here are some steps for replacing the screen on an HP business laptop.

Instructions

Difficulty: Moderately Challenging

Things You’ll Need:

• Laptop with a RAM bay underneath the keyboard
• T-8 screwdriver (star shaped)
• Small Phillips head screwdriver
• Something small, pointy and nonconductive, such as a toothpick or plastic pick
• Replacement screen
• ESD wrist strap

Prepping the Screen for Extraction

1. Make sure the laptop is turned off. Then unplug it from the wall, and take out the battery for safety precautions.
2. Remove the keyboard screws on the bottom of the laptop.
3. Remove the keyboard from the laptop, but you don’t need to fully detach the ribbon connector from the system board.
4. You should notice a pair of wires running up to the screen. These are the wireless antenna. Detach them from the wireless networking adapter. Take careful note of how they were woven around in the system board; you’ll need to reweave the new antenna in the same way.
5. Remove the plastic hinges surrounding the actual metal hinges on the frame. Use something nonconductive to get leverage with, and pop them out without warping the plastic.
6. Use a T-8 to unscrew the screen from the laptop.
7. Disconnect the video cable from the system board. It’ll be a rectangular tan plug that isn’t very far from the screen due to its short, thick cable.
8. Lift the screen up and pull the wireless antenna up with it.

Replacing the Screen

9. Place the new screen into the laptop by lining the two pegs into the hinge holes left in the laptop.
10. Screw the screen back into place. Make sure you can move the screen back and forth before proceeding.
11. Weave the wireless antenna back into position on the system board, and then reattach them back to the wireless networking adapter.
12. Plug the video adapter cable into the system board.
13. Pop the plastic hinges over the metal ones on the screen.
14. Replace the keyboard in the laptop.
15. Reattach all of the keyboard screws on the bottom of the laptop.
16. Replace the battery, and power up the laptop. You should get video on the screen without any issues if all has gone well.

Tips & Warnings

• You may have to disconnect additional plastic pieces during the operation if they are obscuring the view of the cables. Carefully remove those with a nonconductive tool, and try not to warp the plastic in the process.
• Make sure you are wearing an ESD anti-static strap, or are in an anti-static environment, before working on the inner parts of any electronic device.
• It’s very difficult to work on laptops, and any damage done internally may void your warranty. Work on laptops with discretion, and if you have any reservations, consult a professional.
• LCD screens are very expensive and fragile. Be careful not to drop or jar the screen while working on the laptop.
