I'm sorry, forgot to mention I searched for 'error' on my PC, not on the PW.
Oops, just updated my profile details. But it's in fact a PW2, the title is correct.
I just removed the outer frame to uncover the sensor. It looks fine but when I put pressure on it, my PW instantly wakes up from standby. When I release the pressure, standby comes back on. I don't think that's supposed to happen, unless my small finger is magnetic (No, I don't have a prostetic

).
