NP50D5 Backlit Keyboard Problem

Recommended Posts

Hi.
I have a Clevo NP50D5 laptop.
 
Only the blue LEDs on the backlit keyboard are working.
 
All the red and green LEDs have "died".
 
The laptop is 18 months old and all drivers and software are up to date.
 
If I use Control Centre to change the LED colours to red or green, the keyboard simply doesn't light up.
 
Is this is known fault? A loose connection? Something I can fix if I open up the laptop?
 
Thanks.

A loose connection can cause this, there is usually a separate cable for the Keyboard back-lighting, and a partial connection can make odd behaviors.  I have also seen the power supply circuits for the Keyboard Controller chip malfunction, causing interesting behaviors. 

 

Unfortunately, I am not familiar with that particular model of Laptop, and cannot provide more insightful information to how that model runs.
