Dell Latitude E5450-5450 LCD Screen Replacement (5450)

简介

You can use this guide in order to replace the screen of a Dell Latitude E5450 laptop.

There are so many different types of laptop screens available in the market such as transmissive screens, reflective screens, transflective screens, widescreens, backlit LED displays, and many more. I would recommend buying a laptop screen which prevents eye strain.

Every display panel is made up of a series of dots called pixels. In general, the higher the pixel count, the better the display.

To begin with the screen replacement process, you need a Phillips #0 screwdriver. Before performing any task, you must unplug the laptop from a charger or any other device. Then remove the battery which can help to prevent shock.

Remove the six Philips #0 screws from the lower case.
These screws are all 5.6 mm long, but it's still a good idea to keep track of them and make sure they go back in their proper holes!

步骤 2

This photo shows the location of the ten clips that hold the lower case in place. Take note of the location of the clips, and refer back to this step if your lower case gets stuck during removal.
Four clips hold the upper half of the case in place and can be released by prying around them with a spudger.
The other six clips along the bottom edge can not be released by prying at them. Instead, they come free by sliding the whole case upward, as shown in step 5 below.

Insert the flat edge of a spudger into the small divot along the top edge of the case, just below the docking station port.
Pry up to release the two central clips along the upper edge of the case.
