I make use of a Injoo windows 8 tablet. Yesterday, while plugged onto it's power source, I discovered that the battery level was the same after o'er 1 hour of plugging it.

It was quite strange. So I stopped what I was doing on it and left it to charge without using it; so I could observe it. It actually did charge to 100% that way.

This morning, I plugged it in to a power source after using it in the night, after about 1hr 30 mins I came to check it and discovered that it wasn't charging.

I unplugged it and fixed it again. It was showing the sign quite alright that the charger has been pluggged in, but to my surprise the ba3 level went down from 43% to 8%.

I changed chargers like 3rice without any improvement. The worst part is that the ba3 is in-built so it's difficult for me to check it.

Please, what could be the problem? Does anyone have an idea?

Thanks
