Don't know if this has been reported. I got a travel sleeve that has a place on the face of the sleeve to clip the Wacom stylus to. Many times in the sleeve, I noticed the SP2 screen on, the sleeve warm and a lower battery level. After some investigation, I find the Wacom stylus, will wake the SP2, even if the stylus is not moved in relation to the SP2 screen, after briefly pressing the power button to put it to sleep. It can take up to 15 seconds for the SP2 to wake up, after pressing the power button to put it to sleep (not hibernate). The default screen (whatever one gets, when they first wake a SP2 up) can go crazy, with the stylus just resting on it (not moving!!). While the stylus is not moving, the default wakeup screen can be bouncing up and down, before (possibly) settling on the login screen. The SP2 does NOT have the 12/10 firmware update because of an CBS Manifest file corruption (just missed that bullet).
