Installation guide - Replacing a laptop hinge, cable or cover
General guidance for this part type - always follow your device manual- Small Phillips screwdriver
- Plastic opening picks
- Plastic spudger
- Flicker that comes and goes with the lid angle means the video cable is pinched or not fully seated.
- 1Prepare and open. Shut the laptop down fully (not sleep) and unplug the charger. Remove every screw from the bottom cover, including any under rubber feet or labels, then release the clips with a plastic pick starting at a corner near the hinge.
- 2Disconnect the battery first. Unplug the battery connector from the board by pulling the plug body straight out, parallel to the board, never by its wires.
- 3Free the display. Unplug the video cable and the wireless antenna leads, then remove the hinge screws while a hand supports the screen so it cannot fall.
- 4Swap the part. Bezels are clipped or lightly glued; release them from a corner with a pick. Route a new video cable through the hinge along exactly the same path as the old one, with no twists or pinch points.
- 5Test through the full range. Reassemble loosely, power on and open and close the lid fully while watching the picture. Only then tighten every screw.
This is general guidance for the part type, not a model-specific procedure. If the part does not fit without force, stop and recheck compatibility.
