Introdução
If you have a problem with the screen in your Dell Latitude 5580, follow this guide. Some issues users come across include:
- Dead pixels after extended use
- A cracked or damaged screen
- Faulty connectors causing display issues
Follow this guide after troubleshooting and concluding a screen replacement is required. It will require slightly difficult procedures like disassembling the main hinge and a good portion of the internal components. Be careful during the removal of the screen bezel because it is thin and can break, as well as dealing with all the screws and internal components in general.
Before you begin this repair, power off your laptop and unplug it from the charging adapter. Also, disconnect the battery connector from the motherboard.
Ferramentas

Orient your laptop so that you have access to the bottom cover, with the fan vents facing upwards.

Use a Phillips #00 screwdriver to loosen the eight screws securing the bottom cover.

Slide the opening tool or pick around the edge of the laptop until it is fully separated.

-
Use the point of a spudger to push on alternating sides of the connector to "walk" the JST connector out of its socket.
-
If that doesn't work, use a pair of tweezers to firmly grip the sides of the connector and pull straight away from the socket. Hold the tweezers closer to the connector to get a better grip.

Remove the fan from your laptop.

-
-
Use a Phillips #00 screwdriver to remove the single 3.1 mm screw holding down the green Wi-Fi card.
