How to Replace Broken Display Hinge
Today I explain how to remove and replace the broken display hinge in an Acer Extensa 4620z laptop. If this guide works for your Acer laptop and it’s not Extensa 4620z, please mention the model number in comments below.
In this particular laptop I’m replacing the right hinge.
Before you start, turn off the laptop 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 keyboard cover.
When the keyboard/hinge 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 to the display.
Remove screws securing display hinges 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 screen bezel so you don’t lose them.
Start separating the screen bezel from cover with your fingers.
Continue separating the screen bezel and finally remove it from the laptop.
While removing the screen bezel, I dislocated the display latch assembly. 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 of the broken hinge.
Install a new hinge into the display and secure it with screws.
The broken display hinge has been replaced. You can use same steps to remove and replace the left hinge if needed.
Assemble the laptop back together.
