HP Envy All in One 27 p014 brightness Windows 10 Pro cannot adjust brightness, no drivers

[itheadquarters]

HP Envy All in One 27-p014 Product number M9Z75AA

Windows brightness control does not work. 

The brightness control widget appears on the screen and goes up and down, but brightness is not affected by the control.

I have Windows 10 Pro clean install from Microsoft.  

There are no options available to get the OEM Windows 10 Pro media from HP.

There is no display driver offered on the HP web site. 

The only driver offered is BIOS Version/Date AMI A0.07, 11/4/2015.  No newer versions are offered.  No older versions are offered.

I have BIOS Version/Date AMI A0.07, 11/4/2015 as reported in system information. 

I see at least two other posts on this subject and the suggestions from HP reps did not work, although they were creative.  They pointed to a page where to get the OEM media, but only Microsoft media was offered on that page.  Their other suggestions were not a solution.

I would be happy to pay for OEM OS media for Windows 10 Pro.  I would also be happy to pay for a warranty renewal to get support.  I would be happy to pay for a support incident. 

Where can I go from here?

I think the following 3rd party can provide original software

You might want to read this first and try the drivers listed as clearly they are missing when looking up your model number.

Thank you for the links.  Unfortunately they are dead ends in both cases.  Neither are for the HP Envy All in One 27 p014.  I also would not trust third party suppliers of HP operating systems.  That would be asking for trouble in today's environment.

Is HP planning on releasing a new driver that will fix the lack of brightness control on the HP Envy All in One 27-p014 Product number M9Z75AA?  For the amount of money they charged for this PC, I am shocked that HP would abandon everyone who purchased this AIO.  It is time for HP to step up and own this issue.

Will HP make the recovery Windows 10 media available to owners of the Envy AIO 27 p014?  I have read that HP altered the OS to make the brightness work.  Is this true?  HP?  Are you out there?  Is anybody out there?

I have tried all of the following but to no avail:

HP System Event Utility sp91504

Power Management sp113928

.NET Application Performance Enhancement - CPS sp74077

W10 Essential Updates sp94876

AIO Firmware sp96325

Intel Display VERSION 20.19.15.4360 sp74494

Intel Display Version 21.20.16.4821 sp85347

I would like HP to respond to this and suggest a fix to the lack of brightness control on the HP Envy All in One 27 p014 or P000 series AIO PCs.

According to this document your system uses Intel GT2 chipset

try the following driver FOR WIN10

https://www.driverscape.com/download/intel-haswell-hd-graphics---gt2

I don't like that website driverscape but I could not find the Intel driver at the Intel site

question: when you had Windows 8 did the display adjust brightness properly?

What about after you upgraded to 10 did it work the first time?

[itheadquarters]

The brightness was still working before the hard drive died.  I think it had been on Windows 8 and then upgraded to Windows 10, but the brightness did work until I had to do a clean install of Windows 10 from the Microsoft ISO download.  I do not have the media for original OS that came with the PC.  HP web site says it was Windows 10.

Thanks BeemerBiker, but...

I tried the G2 driver you recommended from driverscape, but it said that it was not for my version of Windows.

It is likely the problem is the app that does the installation.  Possibly the drivers are the correct ones.

Try updating the intel display driver and provide a path to the graphics folder where the file was unzipped like the following

The only other thing I can think of is to obtain the original media DVD for windows 8.1 (the HP OEM not a Microsoft iso) for your system, install it and then do the upgrade to 10.

[edit]

I just looked at the 3rd party :surgeon site and your system is listed

You can put in your serial number (product id ?) to verify

You might write to them and ask exactly what you are getting and explain that you need the video driver that was designed for the p014 system.  I looked over at ebay and your p014 are selling with win10, not 8 or 7
