    Touchscreen on laptop becoming disabled

    Hello! I am working on a laptop and have been for quite a while now, and HP isn't willing to help.

    The issue I am seeing with it is the touch screen not working. The model is an HP ProBook 440 G2. I have about 30 of these laptops having this issue.

    When I go into Device Manager, I can disable and re-enable the monitor or disable and re-enable the "HID Touch screen," which results in the touch screen working for about 3-5 minutes, before it stops working again. The devices are still enabled in device manager and absolutely nothing changed (I checked device manager, event viewer, event viewer for the specific devices in device manager and their logs). It just...stops working. The laptops are running Windows 10, and the "drivers" being used for the touch screen is just the standard 2006 Windows generic driver. I have about 4,000 more of these 440 G2 laptops that use the same basic driver and Windows 10, but this specific set of 30 laptops have this issue.

    I tried to see if there was some power saving option, but there is not as it is a basic driver.

    I tried using different Windows 10 iso installations to see if it was an image-specific issue, but even the stock ISO has the issue.

    Not sure if anyone could help me with this...but perhaps there is some secret setting or tweak somewhere that needs to be done to resolve this.

    NOTE: The touchscreen works fine and constantly in the BIOS.

    I am also going to image the laptop to Windows 7 and see if it has the same issue.

    You mentioned HP but you did not mentioned that you had exhausted the recommendations on their page - Troubleshooting Touch Screen issues (Windows 10 and 8).

    Their drivers must be different than your corporate image as they specifically mention Power Mgmt and show it. Realize changing it could cause other "Corporate" issues.
