Yeehaaaw,
i have several probs with my nice XPS 13 2in1.
1.) WK717 Keyboard falls in sleep after short inactivity and needs seconds to wake up
2.) Working with the keyboard intensive ends some but often times in system messages like "the strg button is pressed" or last pressed button like "k" is filling the screen with kkkkkkkkkkkkkkkkkkks. But the button or key was only pressed once.
3.) WM527 Mouse sometimes get lost during work.
4.) Docking station works fine until system inactivity. awaken the xps the screen is flickering. Disconnecting from docking station and reconnecting solves the problem.
5.) PN556W Pen until now ok.
Any fellow sufferer?
