Today I explain how to remove and replace the broken display hinge in an Acer Extensa 4620z laptop.
This guide might work for some other Acer Extensa models too.
In this particular case I’m replacing the right hinge.
Before you start, turn off the computer and remove the battery.
Insert a small flat head screwdriver under the hinge cover and lift it up.
The hinge cover is a part of the keyboard cover.
Remove the cover.
When the cover is removed you can see that the right display hinge is broken.
The bottom part of the broken hinge is still connected to the base assembly and the top part is mounted inside the display.
Remove one screw securing the display hinge to the bottom of the laptop.
If you are replacing only one hinge, remove only one screw.
There are six screws securing the screen bezel. All six screws are hidden under rubber covers.
You can remove screw covers with a sharp object. Glue screw covers somewhere on the bezel so you don’t lose them.
Start separating the bezel from the display cover with your fingers.
Continue separating the bezel and finally remove it from the display assembly.
While removing the bezel, I dislocated the display latch. If you did so, put it back in place.
Remove three screws securing the broken display hinge.
Remove the bottom part of the broken hinge.
Remove the top part.
Install a new hinge into the display and secure it with screws.
The broken display hinge has been replaced.
Assemble the laptop back together.
Also, you can use this guide for removing and repolacing laptop screen and inverter board.
