Lazarus, the camera!

I headed down to Aden Park for Seedy Sunday which is an annual event to do with gardening etc.
I was meant to be taking some photos.
But
After taking a few, I couldn’t see anything on the monitor thing on the camera and the camera was making a beep, beep, beep noise!!
When I got home, I couldn’t find any advice on the “ trouble shooting” pages of the manual. The battery was fully charged.
However, when I downloaded the photos I had taken, they seemed okay.
So, what next?
I tried various buttons and eventually it “came back to life” and it seems to be fine now!!!
Whatever, this is a photo of Lucky who was helping out. She’s a beauty and has a lovely nature.
