    I have thoroughly enjoyed my IdeaTab a2109 for about a year and half, but it looks like it is finally done for with a broken USB charging port (I tried 5-6 different microUSB chargers in 4 different areas). This is the rigged setup that I have to enable possible charging, as it takes 10 minutes+ of various positioning to get it to even charge with tons of downward force having to be put upon it. I saw a post about a $38 usb port replacement part, but it may not be worth it as it may not even fix it. It is a sad day indeed. Any suggestions?

    Ive had this issue on so many devices with micro usb.

    Tip one, never use while charging, that being said, its a tablet and batteries dont last

    so many times the micro usb port dies from movement etc prongs, they wear out or break. so you can try and find the fru part (ive been told its 30 bucks for the little board with it on it) and also im cheap.

    Micro usb should be used for data transfer, i wish manufacturers would add a second small 2 prong charging port like the old days. the tube shaped connectors, they get real small and work. micro usb just doesnt have the mobility endurance.

    So my fix, i removed the micro sd cover and my microsd card,, opened up the back by removing the 2 "+" screws and use a pry tool to pop off the back cover (strt at top and work your way around.

    Where you see the micro usb port on the card is a single resistor (brown block) the top side of it.thats your positive solder connection point. you will also see a 2 gold "I" or "C" shapes with 2 silver points in each one, the larger one is your microusb and one of the silver points in it is your negative.

    grab any usb cable (you may have spares lying around or can buy for a dollar at a dollar store), and cut off the end you would plug into a device.(not the end that goes into your computer), strip the outer rubber back about an inch and cut off everything but the red and black wire inside. Red is positive. black is negative

    get a drill bit just smaller than your cord diameter or the same size and drill a hole in the side cover of the tablet feed wire thu hole and solder to points mentioned....red to top side of resistor (brown block with silver ends) and black to the bottom/lower C shape silver point.

    then use a drop of hot glue or 2 part epoxy to secure the cord so it doesnt pull out. and reassemble

    You may have a cord comming out of your tablet now (you can make it short and while your at dollar store buy a usb extension cable) but you will have a working tablet that can be charged without worring about a positional microusb plug.

    also rembember to point your solder and hot glue gun around and sing the james bond theme... it makes them work better.
