I have an i7 SB with dedicated GPU and sometimes it seems like I am loosing connectivity between my keyboard base and the clipboard. I will hear the hardware chime and the keyboard and trackpad will stop working and then it will come back. If the SB is flat on a desk then it never happens. More if I holding the laptop at angles where the hinge has to support the full weight of the clipboard. The clipboard does NOT detach. Anyone else have this issue?
