Check for frazzed battery? - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

Is there any easy/simple way to check if the battery in a dead P6800 is the bad component (as against a broken hardware issue)
Thanks

Please explain your exact symptoms (sound like a doctor) and full troubleshooting method so far.

Unit won't power up, nor respond with battery icon when charger plugged in.
Given the symptoms tough to do anything else.

It's not the cable as I have a few tabs and docks and everything else charges fine.
But that doesn't tell me if it's a battery issue or a failed hardware component as asked in the original question.

He was just getting you to rule out what could have been a simple cause and hopefully a solution. Unfortunately it turned out not...
Unless you're prepared to dabble in some electronics and pull you tab apart, will just be guesswork.
This user here has provided some useful information, including various pin-outs and wiring schematics etc.

Might be of help for a "do-it-yourself" diagnostics and repair. Else, send it to a service centre.

Keyboard dock not working properly.

I just sold my dock and the buyer has sent me a message saying the dock isnt working.
This is what he wrote to me, it was all working on my tablet before posting.
I have tested it this morning connected to my TF101 and only the keyboard works. The multi touch track pad does not work, the track pad buttons don't work and none of the external ports work including the two usb ports
Any suggestions?
Thanks

Anyone else experience this problem?

Did it work just fine for you? Did you show him everything worked? It may have been damaged when he transported it? Try meeting up again and see if all is well on your end, his tablet has the possibility of being defective.

It worked fine on my tab, unfortunately he lives hundreds of miles away. I have read that some keyboards have stopped working on firmware update, is this true?

I have just had this dock returned and as I thought works without any problems.
Not sure if the guy just didn't want it or maybe certain firmware just dont work with it.

[Q] Battery Disconnect issue

Whats up guys I have a stock Skyrocket on ICS and all the sudden when I plug it in it charges gor like 10 secs and then stops and I get Battery Disconnected error ...Is there a fix ?
Try cleaning the copper connectors on the battery with a pencil eraser. May have some build up on them which is causing a false connection error.

When the battery starts to swollen it means it's time to get a new one, the battery on my old phone started to swollen and I didn't do anything, it end up killing my phone.

what are you waiting for the battery to leak ? or to blast ?
you can easily get a cheap duplicate battery in the market ,if you dont want to invest on the OG one
why risk it out with this defective one

[Q] App or script that shows charging voltage?

Just got a 2.1 amp dual USB carry charger. Is there an app or script that shows charging voltage? I want to make sure the charger is working properly.

Maybe try current widget.
After reading the desription, seems that Moto and Samsung do not support this in their hardware.

No, I don't mean the other way round. I was wondering whether there is a way that I can project my laptop screen on my android. With or without wire.
