Random Sounds Chime All At Once When Opening Laptop
Hi
I have a 2017 Air, and for the past year or so, every once in a while, when I open the cover, random sounds chime all at once, and the sounds have nothing to do with new notifications since I closed my laptop. For example, the other day, both Mail and Outlook chimed at the same time, and while I did have new Mail emails, not a thing was in my Outlook. Just a few minutes ago when I opened it, I had about 4 chimes go off at the same time, overlapping each other so I couldn't decern all of them, but one of them was the camera shutter chime. I wasn't taking a picture, didn't have Photo Booth open, and didn't take a screenshot recently (I opened my laptop several times since the last time). To top it all off, there's no photo in Documents! Does anyone know why it does this? I know my computer's old, it's starting to act a bit funky, freezy, and I need to buy a new battery, but once it gets going, most of the time it's fine. Not sure if this is a side effect of old age, or something is wrong, but would love to get some input to know if I need to do anything!
Thanks!
