How to Replace a Damaged Screen on Dell Latitude 5490

Hello there! Simon here, hoping you’re all doing well. If you’ve stumbled upon this post, chances are, you’re looking to replace a cracked or pixelated screen on your Dell Latitude 5490. Today, I’ll be guiding you step-by-step to ensure a smooth replacement process.

1. Identifying the Problem

When the screen displays irregular patterns, pixelation, or obvious cracks, it’s time for a replacement. Before you start, ensure your computer is turned off. Hold down the power button until it completely shuts down.

2. Safety First – Removing the Battery

It’s recommended to disconnect the battery before doing any hardware modifications. Here’s how:

• Tools Needed: A Phillips screwdriver.
• Procedure:
  • Begin by unscrewing the back cover. The top screws might not come off completely, but ensure they’re loosened.
  • Carefully pop open the back using the opening gap for the SD card or by getting in between the plastic connectors.
  • Once opened, you’ll find the battery connector. Lift it straight up to disconnect.

3. Screen Removal

The most critical step. Here’s a breakdown:

• Tools Needed: Your hands and some patience.
• Procedure:
  • Start by peeling off the bezel, which is held down by adhesive tape.
  • Be cautious around the front camera and microphones.
  • With the bezel off, you’ll notice screws holding the screen. Unscrew the ones on the top corners and the bottom.
  • Tilt the screen gently towards the laptop’s body to expose the connector tape. Peel this tape backward but avoid yanking or ripping the cables.
  • Disconnect the screen’s connector.

4. Replacement

Now, the main event.

• Tools Needed: The replacement screen.
• Procedure:
  • With the new screen, connect the cable by sliding it in, ensuring the metal clipper is open.
  • Push the connector all the way in and clip it down. Reinforce with the blue tape.
  • Position the screen and screw it back in.
  • If your bezel’s adhesive isn’t sticky enough, use 3mm double-sided adhesive tape.
  • Finally, reconnect the battery and screw back the back cover.
