My laptop, for instance, (a Lenovo ThinkPad X1 Yoga 1st) disables keyboard (the keys are physically blocked when the laptop is at an angle > 180°), but touchpad and trackpoint are still functional. However, my friends laptop (some Lenovo non-ThinkPad Yoga) does not physically block anything, so when using it on some non-flat surface (like legs) you get keypresses. > So, Windows 10 prompts me whether I want to switch into tablet mode as soon > as I open the laptop slightly more than 180°. With the correct touchpad driver > installed the touchpad is turned off automatically at that point (whether > enter "tablet mode" or not). So does mine. However, on my laptop, by listening to the acpid socket on Linux, I noticed that no event is actually triggered when the angle changes around 180°, aside from the backlight brightness change (my laptop automatically turns off backlight when the keys are blocked, and turns it back on afterwards). Tablet mode is only triggered when it gets close to ~345°. I don't know what actually happens under the hood on Windows, but if we have some way to detect this too checking for keyboard backlight change doesn't seem good to me -, it should probably be exposed somehow.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
