It is sort of stubborn about switching off as soon as i close the lid. The tracker is correctly listed on the device manager as camera all the time, showing no error of sort. The only error return is appearing on the bottom edge of Tobii app when i try to do something with the lid closed. It says “no eye tracker connected” and gives me no chance to proceed any further.
If I uninstall then re install the app (luckily a matter of seconds) the Tobii4c will work again. In fact I am about to play Soma like that. Cheers
