Dear sirs, I had bought Harman Kardon Go Play (White) It has been almost 2,5 years. I am really a great fan of this brand and the device also. I never want to change it. In first year I changed the battery. It died. And now, it died again. I can only use it with electricity , plugged in. What are the reset buttons of this device? I pressed "BLUETOOTH" and the "+" button = It says "Three and four" I pressed "PLAY" and "+" button = The Red light blinks and swtiches off Here in Turkey it is 80$ for a service and new battery. I don't want to give 80$ every year to change the battery. What should I do? Thanks Bubu
