My Forerunner 305 would not power up after a charge. Moreover, it would not register as being on the charger when I plugged it in. I held the Mode and Lap buttons down for 10 seconds, then after pushing and holding the power button twice, it finally powered up. However, the only way I can power it up now is to repeat the Mode-Lap button hold for 10 seconds, followed by holding the power button (5 seconds) and releasing twice before it will power up. The battery shows full charge. How can I get this thing back to working as it should (i.e., powering on when I press the power button)??
