Garmin Forerunner 305 will not turn on after charging.

My Garmin Forerunner 305 running watch was not turning on after charging.   This instructions should reboot the watch and turn it back on.

1.  Press the mode button and then the lap button.  Hold these buttons for at least 10 seconds before depressing the buttons.

2.  Press the On button.


These instructions are good to remember as you might need to do this before a race.
