HP Envy 32 AIO freezes/lockup

[Morphaniel1]

So BernardoT asked this question in April and got a stock answer about resetting his PC. Like him, I am getting a random lockup with my device about 1 per week (it remains switched on at all times). There appears to be a link to the camera driver because after the fans speed up to full speed and the system locks up you have to reset using the power switch: the computer always fails to initiate the camera properly when it reboots - Windows Hello, which I default to face recognition, says the camera has failed and I need to enter a PIN. Shutting down the machine properly at this stage and restarting it reinitialises the camera OK. I very rarely have the problem when the machine is hibernating - it is almost always while I am using it with the screen on. My camera is always popped up and I am frequently on Microsoft Teams so a Teams-Camera-Driver clash cannot be ruled out. There is nothing in the event logs connected to the lock up and all my drivers etc are up to date both so far as HP is concerned and Microsoft also.

To bypass your issue, can you "disable" the onboard camera, and purchase a web-camera/microphone, and use it?

I do not understand why the fan speeds-up.  Does Windows "Task Manager" show which task is consuming the most CPU resource?

Switching the camera out is something I could try fairly easily, though it is a major feature of the device and of Windows Hello of course so I could only regard it as a diagnostic step, not a solution.

As to the fans, I assume they are responding to a CPU panic, either of the GPU or the CPU but since the machine is locked up solid there is no chance of checking Task Manager...

Sigh. I typically have Task Manager running all the time, and as a "minimized" window.

Usually, I can use "SHIFT-TAB" to cycle through the Windows, to "restore" the window, when the CPU seems to hit 100% busy.

My HP Envy All in One 32 a1785ng  is also affected.

Any idea how can we force HP to fix the issue?

Issue description:

The camera issue is causing freezes/lockup on ENVY's 32 All-In One:

GIVEN the device was turned off/hibernating/in sleep mode

WHEN we turn on/awake the device

THEN *randomely* the device freezes/lockup on the lock screen trying to initialize the camera

OUTCOME:

- It's barely possible to use Windows Hello on the device

- The issue has an impact on the performance of the device

- It's very annoying to the user if there is something urgent to do on the device and the only thing they can to is to keep staring at the lock screen till the device is ready

It's been several months and HP didn't release any upgrades of firmware for a while.

Here are other issues affecting HP ENVY 32 and all are related to BIOS/firmware:
