My Columbus P-1 GPS logger has died.
The P-1 GPS will not charge or turn on. The charging light does not turn on when plugged in to a usb charger. It also will not turn on when the power button is pressed.
There is a small hole next to the usb port in P-1. You can insert a pin to reset the unit. Please connect the charger and do the reset at the same time. After reset, the P-1 will become normal.
