Brightness control keys not working

Spectre x360
Microsoft Windows 10 (64-bit)

I have the strangest problem... When on battery (and only when on battery) my screen brightness keys (f2, f3) don't work. When I press them, the popup appears in the top left, but it won't move up or down with the keys. Using the touchscreen or a mouse I can drag it and it does indeed adjust the brightness. When plugged in to charge, the keys work as they would normally. I have tried disabling and enabling the "Generic PnP Monitor" device as well as reinstalling graphics and chipset drivers. I also tried changing the power profile and obviously restarting. Any ideas?

Brightness control keys not working

Hello@adriangb,

 

Welcome to the HP Support Forums!  It is a great place to find the help you need, from other users, HP experts, and other support personnel.

 

Brightness control not working on battery on the PC. Did I get it, right?

 

I recommend you to uninstall the keyboard driver and restart the PC using only the battery and check if that works.

  • Start Control Panel, click Hardware and Sound, and then click Device Manager.
  • Expand the node that represents Keyboards, right-click the device entry and click Uninstall.
  • On the Confirm Device Removal dialog box, click OK to start the uninstall process.
  • When the uninstall process is complete, restart the PC.

Note: Do not check the box which asks for the confirmation of deletion of the driver.

 

Hope this answers the question. Please let me know more.

It didn't work. Also, it never asked to uninstall the driver. I did the PS2 Keyboard, not the HID device

Brightness control keys not working

I had tried both already, but (1) doesn't apply because I AM able to change the screen brightness, just not via keyboard keys while I'm on battery.  I tried (2) and it didn't do anything. I also Disabled/Re-enabled the Generic PnP device to no avail.

Hi@adriangb,

 

Thanks for the response.

 

Then, try the link below and update the BIOS update and chipset driver as well and check if that solves the issue.

 

BIOS: http://ftp.hp.com/pub/softpaq/sp77501-78000/sp77784.exe

 

Chipset Driver: http://ftp.hp.com/pub/softpaq/sp72001-72500/sp72025.exe

 

Hope the information shared will help you. Please share for more.
