Hello ,

I have the same issue .

I tried to update firmware to version F.16 Rev.A and problem started ....

Immediately after the update my screen dimmed...very low light .

I have to close laptop screen and open it again if i want to work with a normal brightness .

Any idea about new firmware ?

Thank you

[Riddle_Decipher]

@adminakos You may want to turn off the adaptive brightness and night mode, using the below steps to resolve this issue:

1. Go to Control Panel > Hardware and Sound > Power Options, then click on "Change plan settings" next to your active power plan.
2. Click on "Change advanced power settings."
3. Scroll down to Display, then under Enable adaptive brightness, switch it off for both the battery and plugged in modes.

Night mode:

1. Open the Start Menu.

2. Click on the gear icon

3. Choose System

4. Select Display.

5. Toggle the Night light switch to Off. 

6. Click Night light settings to adjust the level of blue displayed,
or determine the time for Night Light to activate automatically.

Hello Riddle ,

I fixed the issue with Bios --> activate legacy mode .

Now everything is fine inside Windows 10 OS but bios still Dark (extremely low brightness)

Do you have any news about new firmware ?

Thank you

[Riddle_Decipher]

@adminakos I'm afraid there are no firmware updates as such as of now, have you tried turning off the adaptive brightness and night mode, to fix the low brightness issues? keep us posted once your done with the steps.

If that doesn't help, you could recover the last known good working BIOS: Click here for steps.

hi there Riddle,

thank you for keeping up with our problem. But as Cyberkos and myself mentioned above by reverting Bios (to any previous versions as I ve checked them) is not solving the issue. What do you mean with last known bios, btw? Bios f16a is still on official site and laptop is in delivery's condition except bios new version that HP proposes.

Also previously mentioned that it is UEFI problem, not standard Bios. I m sorry that I cannot accept as solution what you proposed (carrying an HP badge) as Cyberkos' solutions worked far too early than engineer's ones.

In addition I really hope that HP is working on a new bios update. No contact from any HP representative (not sure if you are one or you are just helping us out for your own reasons) so far. It is a faulty machine since I can t access bios features (impossible to see what I m doing with such brightness) and warranty seems not to covering it. Whose fault is this?

Hi @NGKR

I have brought your issue to the attention of an appropriate team within HP. They will likely request information from you in order to look up your case details or product serial number. Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post personal information (serial numbers and case details).

Thank you for visiting the HP Support Community.

thank you Asmita (i guess Riddle has contacted you and i thank him for that) although i have already brought my case to my retailer and there is a case in HP Greece. I will be waiting for  HP tech team's respond and will be as helpful and cooperative as possible in order to solve this issue

[NGKR]

Problem remains. UEFI features are impossible to be managed due to extremely low brighteness. My HP support assistants have closed the case with no solution for that

I hate to say this guys, but HPs become notorious for making firmware changes and breaking stuff on their products then abandoning customers and never resolving the problems they created. I'd return your laptop as a warranty failure rather than dealing with it in these forums. All you'll get here is the run-around until they tell you your product is no longer supported. The chain to the engineers is broken and has been for a long time.

Good luck and sorry you guys are dealing with this!
