I just bought a refurbished samsung galaxy tab 10.1 P7510 model. when i try to charge the tablet it continuously plugs and unplugs itself. it came with around 15% battery charged when I got it but as I wanted to charge it, it charges up to around 38% and would not charge further. when i try to charge it, it charges for 2 seconds and discharges itself and the process continues until I take out the cable from the tablet. I know the galaxy tab cannot be charged on your computer. i was charging via adapter that came with the tablet on my outlet. please help me with the situation. I even tried to factory reset it, but it doesnot work.
