So I have had my OP-1 for about 2 years, and just recently it will sometimes not turn on if its close to low battery according to the LED meter. The first time this has happened it would not turn on or charge when i plugged it into my computer. But after some time when i would check and turn it on, it would power on and give me a chance to plug it in and charge it. It has again not turned on tonight, but I am sure the battery was low, but it wont even let me charge it. Does anyone else have this problem/ have any advice as to how i can charge it even though it is turned off. Any help would be greatly appreciated.
