My 3 year old Galaxy Tab 2 10.1 that won' charge

[AC Question]

Suddenly I have a problem charging my Tab2. I haven't had any problems before. If I plug it into a plug socket it immediately turns off the tablet and doesn't charge. If I plug it into the pc it stays on but has a red cross in the charging symbol at the top right. I have tried (without success):
- blowing into the socket
- holding the start button down, and also the start and volume button down for 30 seconds
- turned off wifi (although it has always charged fine before with it on)
- tried unclipping the battery connection and replacing it
NOTHING works
Also, with wifi on I now cannot connect to the internet with google.
I now have little charge left in the battery and have no idea what to do.
How would I know if the battery needed replacing?

I assume you did try another charger and cable, correct? From your description it really looks like the USB charging port (or beyond) is bad. It could be that perhaps there's a short in the USB connector, or the charging module, since the tab is shutting down when you attempt to charge it. Worse than just being the charging module, it could be the motherboard. I doubt it's the battery from what you describe. You might want to consult a repair shop to see what they say.
