Mpc Live Open by itself

Hello Guys and sorry for bad english.
My Mpc Live starts by itself. Sometimes it happens immediately after shutting down the machine. Some other times opens randomly through the day.
Does anyone else has the same problem or am i missing something to the settings of my MPC?

Thank you in advance for your response.

that does not sound normal, not witnessed that behavior on my units. can it be that there is dirt in the on/off switch? seems like the only reason for this behaviour is that switch triggering by itself...

Power Switch seems defective?
