Query: Flawed power circuitry

I had one of these for just over one year when the power circuitry failed. The symptom is that the camera will power down after less than a minute even with new or fully charged batteries. From my research, this is a wide-spread failure mode for this camera. Communicated with Canon. No joy. I loved the camera while it lasted but I won't do business with a company that will not support their product. I've had six Canon's over the past few years. But unlikely to buy another.
