Help Tab II won't charge

[REALOldNick]

My tab will not charge or start.

The cable failed and the battery became VERY low. I ordered other cables and turned off the tab.

When the cables arrived, they would not charge the tab, even overnight. The tab will not start and shows no sign of recognising the charge.

I do not know if it is dud cables, too flat a battery, or machine fault.

I wondered about charging the battery externally to maybe kickstart the process. I had a phone that behaved like this when the battery was totally flat. I have the proper charger to do that. Does anyone know the pinouts?

I cut one of the cables. It has 4 wires, braided shield and foil shield. Will this suit the tab? The cable that did work before was not configured like that.

Samsuck wants $40 for a cable. In desperation I would do it, but not to find it is the tab or battery.

Any help appreciated.

Check the micro USB input connection

While Samsung devices are very fussy about cables, any standard micro USB cable should charge your Tablet. I'd check the charger itself. Many phone chargers don't offer enough amperage to charge a tablet (or they charge it so slowly it's not detectable).

I have a Note 10.1 that charges the fastes when I plug it into an Anker battery pack. I can charge it from 20% to full in about 2 hours. If I use the charger that came with it, it can take over 8 hours to get to full.

samsung tab 2 10.1 arent micro usb. my charger failed too, first it would have the lightning strike symbol on the battery icon and would charge painfully slow then eventually stopped charging. new charger worked fine.

Sorry, didn't realize it used the old proprietary connector. How old is it, if I may ask?

 

[REALOldNick]

Thanks for the replies.

The charger is fine. It is the genwine Samsung one and charges other stuff OK. I have also tried other chargers.

The tab would be ...5 ...years old. It has the wide socket ...30 pin?.

Does anybody know the pinouts of the battery?

I resurrected my Tab 2 10.1 after my son left it in a corner for several months. I left it on the charger for a day and a half before it would start.

Here is a pinout of the 30-pin connector.

Hi. Yeah done that with the long charge.

Dang! What I want is the battery pinouts, so I can charge it up and see if the tab is OK.

What I meant to say is... Sometimes it's the connector itself, it wears out in a way.

 

[REALOldNick]

Yeah OK. I will crack the tab open and have a look.

I'd still like to try charging the battery ecternally
