Power port broken

time to bin it and buy a new one

check ebay for charge port parts for your particular tablet.
if parts are available open up tablet and change the broken charge port.

all tablets can charge while you are using them, on rare occasion the battery will completely discharge and will need to be charged to the minimum before operating the tablet.

Incorrect port part, Wrong polarity for wires connected to the port or poor connection of wires to the port.

The power port is damaged - most likely the solder joints are loose or broken. You need to find a store where someone can open the case, order the new part for the tablet and then solder the new power port to the board.

Then it will be as good as new.

I have replaced power ports on laptops, phones and tablets.

just google it many wideos on it.

See with a magnifying glass if there is any green oxides in the port on the contacts. If any use a fine needle to clean them out while the battery is out. This often fixes the problem. But if it is physically broken you may need to buy another one with broken screen and take apart ( tools are sold on ebay with instructions) and replace the port. Sometimes you can just buy a port on ebay.

Honestly, even if you could find the part (not likely - tablets are commodity items these days), you would need specialized tools to de-solder the remainder of the old port and solder the new port, and you would risk damaging other components because of the proximity of parts on these small circuit boards. If you want to take it on, research who actually builds the tablet and contact them about parts. A better option might be to find one with a broken screen or some such (check local 'for sale' sites) and try to swap only that part (if the charging port happens to be connected to a smaller 'side' board rather than the main board). Tough one. Good luck.

If it's just loose, you can snap it back in. If the port is broken off the ribbon though, you can always try to replace the broken part yourself first. search model name plus "repair guide" on any search engine.They will show details about about part replacement etc. in detail. There are other websites that sell all the replacement parts, one of the bigger ones is http://portatronics.com (646) 797 2838. Then for the repair itself you can venture to do it yourself, or better ask a friend who has done a similar repair before.
