Hello. My name is***** can assist you with your question.
This is likely a physical problem with the button itself send you have Artie replace the batteries. But I would suggest doing is cleaning out that area around the button with compressed air – you can get a can of compressed air if you don't have one, at a local office supply store. Use that to ensure that there's nothing interfering with the contact of the power button and then test. Let me know how you make out.
