Today, I took my H130 to the radio station to record my show (I record from line out to MP3 from the air board while I do a 3 hour DJ shift on college radio). I made sure the H130 had a decent charge before going to the station. Once there, about to start my show I pressed the On button and got no response.... zip! I tried a dozen more times and nothing.
Therefore, I got no recording. Once home, I plugged in the charger and pressed the on button and voila, on! I removed the charger about 2-3 minutes later, turned the player off, then on and it powered up and showed 3.99v on the battery, nearly a full charge (I'm using Rockbox). Why in the world wouldn't the H130 turn on earlier????
