For the last couple of days I have heard an occasional 'ding/bong' sound in the house. I tried and tried to identify where the sound was coming from. Last night my wife was using the iPad (WiFi) and about 30 minutes after she had turned it off, the iPad went 'ding'.
I checked my laptop this morning and I had received a gmail message at exactly the time the iPad went 'ding'. So, this morning I sent myself a gmail message from the laptop (the iPad is off) but, no 'ding' so far (about 1 hour)??
What else could cause the iPad to ding occasionally - a couple times a day - only when the iPad is off? The iPad did not do this for the first couple of weeks after I first bought it - only in the last few days. How can it 'ding' when it's turned off?
