HP Elitebook 840 G5 lower brightness on some laptops compared to others

Elitebook 840 G5
Microsoft Windows 10 (64-bit)

Hi all

 

I have attached a photo of 2 x 840 G5s placed next to each other. As you can see, the one on the right has a darker, creamy shade. I have tried uninstalling the driver and getting it from HP website, the brightness is maxed out, tried updating windows and all and yet no luck.

 

I have come across 20+ laptops which have the same issue. Is this something well known? The difference is really disturbing for the eyes when you need to work in front of a laptop with this issue.

 

Would this be a panel issue (backlight not working properly) or is it software related and I am missing something out? Any tip/advice would be greatly appreciated.

 

Regards

I think HP needs to work on BIOS of the Elitebook 840 G5 series. We have screen problem which I posted in IC forum. I will move it out IC sometimes next month (August) because I'm waiting more info from HP.

 

I tried to update to latest BIOS, latest Intel video ... but still no luck.

 

Regards.

@Banhien

Thank you for your reply. Are you positive this is a BIOS related issue? I need to narrow it down because what I am afraid is that soon users will start seeing the difference themselves, I have no solution and might end up raising hundreds of RMAs
