I have the V4 version. Sometimes it does work though and sometimes it stops working when I wake the machine, having to reboot 10 times to get it working again. When I get it working, it will work fine for a couple of weeks sometimes and sometimes it will stop working serveral days in a row. Now I’ve done 10 reboots and cold boots, nothing seems to work. Even booted Windows, doesn’t work there either. Took a look in the device manager, has some errors but no on the touchpad.
