No touch screen detected

[tim687]

I am struggling to get the touchscreen of my notebook working. I tried all the things that are listen in several other post on the HP forum, and none of them worked.

My system is up-to-date running Windows 10 Home (64-bits) with 4GB of ram (the other slot is dead)

What is strange is that I can't select the component touchscreen in the UEFI diagnostics, however I am sure that the notebook has a touchscreen.

I contacted eGalax because I saw the touchscreen in my device manager (unplugged) and asked them for the drivers, there response:

Dear Tim,

 

The touch screen on HP Pavilion SmartTouch 15-b107ed don’t need to install any driver.

Windows 10 can load internal HID driver for it automatically.

According the pictures, it is not touch controller. Touch controller is connected at USB interface.

You can try to re-install Windows 10. If the problem still occur, we suggest to contact HP for support.

I don't know what to do, the touchscreen worked a few years ago.

What I do see is an unknown device with the following details:

Location: PCI Express Root Complex

Path to device: ACPI\HPQ0004\3&2411E6FE&0

Hardware Id's: ACPI\VEN_HP&DEV_0004; ACPI\HPQ0004; *HPQ0004

Problemcode: 000001C

BIOS-devicename: \_SB.PCI0.ACEL

Enumerator: ACPI

Bustype GUID: {d7b46895-001a-4942-891f-a7d46610a843}

Hash reported device id's: 4D576B5B

Location paths: ACPI(_SB_)#ACPI(PCI0)#ACPI(ACEL)

Name of physical deviceobject: \Device\000001C

Could this be the touchscreen controller or something? I tried installing the HID TouchScreen driver, but it didn't work.

Thank you in advance for your help,

Tim
