1, the tablet is good (Samsung galaxy P7510), can run normally.
2, the data line is original, the charging head is also, the power can not be charged, the link computer does not respond, can not charge, can not synchronize
3, get the Samsung repair point, the technical staff said that the motherboard is broken, to change a motherboard, the price is close to 2000 yuan!
Above, I think that it is impossible for the whole motherboard to be broken. After all, the tablet can run normally, but it can't be charged. As a result, the last tablet runs out of the last power, and now it can't be turned on. I wonder if the capacitor for charging is broken? Do you know anyone who knows this, please help me with some trouble, thank you!
