The brightness adjustment stops working until I reboot the computer

[Jimbo1954]

The brightness stops working until I reboot the computer. Every time I go to adjust the screen brightness it doesn't work. Then I reboot the computer and it's working again. I'm not sure the time frame before it stops again but today I rebooted this morning and it was working but 5 hours later I tried it and it wasn't working again.

I have the same issue since last graphics update few weeks ago (never had this issue before). After a while the brightness cannot be changed anymore (including from control panel) and only rebooting works. I installed latest drivers directly from Intel and from Nvidia but still after a while it stops working. Seems a regression in the Intel driver. Any fix available other than use the previous Intel driver? Note I tried to use support HP site but my serial number is not recognized (workaround I found is not to login and enter product name).

I have these drivers:

Intel(R) UHD Graphics 770: 7/24/2024 - 32.0.101.5768

NVIDIA GeForce RTX 3070 Laptop GPU: 7/30/2024 - 32.0.15.6018

Note when I rollback the Intel UHD 770 driver in device manager to 6/10/2024 - 31.01.101.5590, brightness works again without a reboot. So I suspect Intel driver is to blame. But not sure yet this will fail after a while too since I think that was the previous driver that failed.

[Jimbo1954]

It's still doing it for me and I'm completely up to date with drivers through Windows update. I will try the intel site and see if they have a solution.  Thanks.

I went to Intel site and installed a newer latest driver but after while still breaks brightness control. I'm trying now the previous driver on HP support site for Intel graphics which in theory should work since I didn't have this issue before.

UPDATE: installed 'previous driver' from HP site for Intel graphics driver and so far seems to work. Need to give it bit more time to be certain (version 31.0.101.5592, 6/19/2024).

[rogerkl]

Since I think this is a bug in latest Intel graphics driver, you could try to install the previous version.

Go to HP ENVY 34 inch All-in-One Desktop PC 34-c1000 Software and Driver Downloads | HP® Support then select OS version and under 'Driver-Graphics' click on 'Previous version' (Intel High-Definition (HD) Graphics Driver 31.0.101.5186 Rev.A).

I tried that yesterday and so far seems to be working but will give it few more days to be certain.

Device Manager shows now this version for me:

Intel(R) UHD Graphics 770 Properties

Intel Corporation

6/10/2024

31.0.101.5590

Seems still not that old, but you could get older versions from Intel site as well.

Unfortunately that didn't last. after couple of hours brightness again can't be changed and that's with all latest drivers:-(. Never had this issue before with having all latest drivers.
