Battery won't charge up - only works when plugged in.
It got to the time when the battery needed to be replaced, or so I thought. I took it to a repair shop who installed a new one, after which they told me I was good to go. Once the battery had reached its max paying time, I plugged it in (for several hours)for it to recharge. However, when it came to unplugging it in view of listening, again the battery stated it was out. I tried different chargers, both through the mains and a computer. So, I brought it back to shop where I left overnight so they could take a look at it. The next day, I returned to find that they had tried multiple batteries but the device still wouldn't charge. I can now only as a consequence listen to it plugged into the wall. I suspect there is something wrong with the motherboard but not too sure. Can you help?
