[NAME]   very odd but I have a few ideas. Have you reviewed this article [URL] and this troubleshooting guide? [URL] There is also this which may explain intermittent issues: [IMAGE] Can it be a hardware issue?    
The begin october updates pushed me to re-install some drivers. My touchpad is still behaving curious. Sometimes it refuses to work (no pointer), sometimes it works out of the "blue". In diagnosis  or support assist HW seems to be ok. I have done all the hints given in the knowledge base.So probably a driver issue is still pending. Can anybody hint what drivers for the XPS 13 2-in-1 9365 are responsible for the touchpad. I have reinstalled all the mouse drivers (the HID mouse and PS/2 driver under "mouse and other pointer devices") and the "HIDtouchpad" find under "human interface devices". By re-installing and re-setup, i got the touchpad working sometimes. So besides the 2 mentioned what other drivers need be re-installed for a secure operation of the touchpad.  Please advise. By the way all the re-installed drivers are time stamped in "2006" which i find also quite odd. I assume there are supposed to be later versions.Thanks.
