The camera was being used outside n a solar charger for a few months.  I moved it to a new site a nd a new location.  Reset and readded while plugged into an external charger.

Everything appeared to be OK.  The battery shows 100%.

But, when you remove the wall charger, it will not power on.  Even if you attched the solar panel, it will not power on.  It will only work with an external charger plugged in.

Any ideas?
