Laptop Screen "Flickering" When Moving Lid
4.5
The screen flashes or changes colors when you adjust the angle of the laptop lid.
Symptoms
- Flickering
- Lines on screen
- Blackout
Possible Causes
- Loose eDP cable
- Frayed hinge cable
- Damaged LCD connector
Step-by-Step Fix
1
Test External Monitor
If the external screen is fine, the problem is definitely the internal cable or panel.
2
Update Graphics Drivers
Rule out software before assuming it's the cable.
3
Reseat the Display Cable
Requires opening the laptop to ensure the wide ribbon cable is firmly plugged into the motherboard.
When to See a Technician
The cable that goes through the hinge is flexed every time you open the laptop; eventually, the tiny wires inside can break.
