This is a guide on installing a screen onto an .

As you can see, this laptop does not have a display at all, it got damaged in an unfortunate dismembering accident.
But it still works and displays video on a new LCD.



This is the old assembly and it has its Wi-Fi cables severed and has several scuffs and bruises, as well as its LCD is fully cracked.
Here we have another display assembly with a 300 hz LCD that we'll attempt to install.


Shut down the laptop, disconnect the power cord and remove the tester LCD.
Flip the laptop body over and begin by removing the back cover screws.

There are four phillips screws on the bottom edge, the two corner screws are longer than the two inner screws.

Remove two more screws in the two upper corners. Then remove the final two screws from the sides.
You may need to pull out the screw and support it with your fingers to get it out fully.

Use a plastic pick to open the back cover, set the back cover aside.
Disconnect the battery by lifting the securing tape and pulling away the connector. Tuck the battery cable out of the way.

There are two more phillips screws on the back panel. Remove both of them.
Use a plastic pick from the side to shift the back panel forward.

Lift the black plastic and disconnect the back panel lights connector from underneath.

Push on both sides of the back panel evenly and separate it from the laptop.

Remove four phillips screws on the right hinge mount. Remove four more phillips screws on the left hinge mount.
Remove the left hinge, then the right hinge.

Pick out the video cable from its guiding channel, lift the securing tape, use a plastic pick to open the connector bracket, disconnect the video connector and a tiny connector immediately next to it that is also attached to the same cable. Remove the video cable.

Remove one phillips screw from the wi-fi connectors bracket. Remove the bracket. And using a plastic pick pop off the two wi-fi antenna connectors. Remove the old wi-fi cable.

At this point the new display assembly can be installed.

The new LCD is working and we're done!
