How to know your display cable has failed
The HP EliteBook 840 G5 G6 LVDS cable fails after years of opening and closing the lid — the cable flexes thousands of times and eventually a conductor cracks. Classic symptoms: the screen flickers when you wiggle the lid, vertical lines appear at certain hinge angles, the display goes completely blank when nearly closed, or one of the colour channels (red, green, blue) drops out. None of these means your screen is dead — replace the cable first.
Diagnostic test
Connect an external monitor via HDMI / DisplayPort. If the external monitor shows a clean picture, the GPU is fine and the issue is the panel or the cable. Wiggle the lid: if the laptop display reacts to lid movement, replace the cable first — it's 5x cheaper than the panel.
Installation
This is a 30-minute repair. You'll pry the bezel, unscrew four LCD mounting screws, lay the panel forward, peel the cable's adhesive backing off the panel, unclip the connector and replace with this unit. Route the new cable through the hinge channel exactly as the original — twisted routing will fail again.

Frequently asked questions
Is this a new or used cable?
This is a pulled-tested cable from a working donor laptop, tested for continuity and signal integrity. Many failures are conductor cracks from years of lid-flex; a healthy donor cable will outlast another panel cycle.
Will this cable fit my HP EliteBook 840 G5?
Yes. This is the original-spec part for HP EliteBook 840 G5 and all variants in the compatibility table. The 30-pin eDP connector matches the motherboard side exactly.
My screen flickers — is it the cable or the screen?
Most likely the cable. Test: connect an external monitor — if external works fine and the laptop screen flickers when you angle the lid, replace the cable first. Cables fail far more often than panels.
Does this support touch displays?
This is a standard non-touch eDP cable. Touch variants of this laptop use a different multi-pin cable — confirm by counting pins on your old cable before ordering.
Can you install it for me?
Yes — Lahore walk-in installation costs Rs. 1,500 and takes 30 minutes. Free if you buy panel + cable together for a complete display repair.
