Hi All. The Synaptics USBus TouchPad on my HP EliteBook 840 G3 Notebook recently stopped working. I booted it up one day about a week ago and it was not responsive. It is "on" in touch pad settings and enabled when I check the mouse properties.The device status is that it's "working properly" and hardware/device troubleshooting does not detect any issues.
I'm not the smartest with computers but thought I'd initially try fixing the issue myself before asking for help. After looking for advice online I tried both updating the driver and then rolling back to the old driver (rebooting after each change) but it was still unresponsive. I then uninstalled the drivers and reinstalled from the HP website (after entering my serial number to make sure it was the correct driver) but the pad remains unresponsive. The driver version from HP was the same one as was uninstalled so it did seem to be the correct Synaptics drivers (version 188.8.131.52, dated 16/Dec/2018).
I'm thinking it may still be a driver issue (rather than a mechanical issue with the pad itself) as after uninstalling the Synaptics software, the notebook defaulted to the generic Microsoft "HID-compliant mouse" and the touch pad was then responsive but not working correctly - the cursor moved around (a bit jerkily) but would randomly left or right click so was unusable and the pointing stick (Synaptics TouchStyk) was the same. After reinstalling the drivers, the TouchStyk now works fine but the TouchPad is not responsive.
I've noticed the location of the TouchPad is showing as "plugged into PS/2 mouse port" - not sure if that's normal? I don't have anything physically plugged in to the mouse port but perhaps this is not what it means (as you can tell I'm not great with IT!). The device info for the TouchStyk however says "Synaptics TouchStyk V2.0 on PS/2 Port 1", this may not be useful information though...
If anybody can suggest what I could try next I would be very grateful!
Many thanks for any help or advice,

I would suggest you to install the latest Touchpad Pad driver for the unit:
And it should work fine with this update.
