Hey guys, need URGENT HELP on charging! - Android Q&A, Help & Troubleshooting

Hey guys, recently bought an Onda V811 Quad Core android tablet (a Chinese tablet).
2-3 days ago i could charge through USB cable plugged into a laptop and a AC adapter to charge on the wall.
But the next day i couldn't charge, i tried plugging the USB in the laptop and the wall charger and it still didn't charge.
My tablet still has 11% of battery left, My tablet works fine, everything works fine smooth and brilliant, it's just the fact that i cannot charge through my USB cable anymore. idk why =(.
I could turn it on and everything is functional, except battery charging.
I also tried hard reset and factory reseting, that didn't work either.
is anyone here at XDA an expert at tablet repairs/fixing? that can help me?
That would be much appreciated. Thank you

1) Try a new microusb cable
2) Try another USB port from laptop
3) Reboot the tablet, and if the problem still there, try at least, off-mode charging
Well, finally , if you does not resolve the problem, seems that you have an hardware ,,error,, (short..), so go to a service.

Well, i have just tried everything you listed, doesn't work, i guess its either the battery is dead or the port has something wrong or wires wrong.
B ut then again, if the battery is dead, how come i can still use my tablet with its 10% now left?

Well i do know that it isn't the chargers fault, since i am using a charger from Xperia SP phone, it chargers perfectly on my phone, but when i plug it into the tablet, it doesn't charge. And i also tried using the normal tablet charger, but still no use. Can't charge at all :'(

Now i understeand that the problem it`s coming from the tablet, more exacty from the charger microusb port.
Solution: Buy an universal battery charger from an elecetonics store, and everything would be ok.
Something like that:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So everytime when you battery discharges, recharge it out from the tablet. Pleasse Hit thanks !

Here you go: http://www.aliexpress.com/store/pro...um-battery-3-7v-4500mah/315565_898803195.html
But it seems like will be hard for instalation, because it have wires with it. So i think it will replaced on tablet`s hardware.
If you does not know what are you do, call an Onda Service. Helped you?
P.S. : This product does not exist on ebay store.

Well, you just put the battery in, then connect it to a wall socket, and wait until an LED flashes.
BUT this solution won`t work for you because, it seems that your battery it`s integrated in tablet`s hardware.

No sense in wasting any money. The usb port on the tab is probably bad,or the voltage regulation part. I will assume the port is the same for both USB and Wall Charge? If so, there's a hardware malfunction on the tablet.
If you can not return it for an exchange or the warranty is expired, then you could possibly open the tablet and look for any type of loose connection near the USB port.
Does the PC still recognize it when you plug in the USB?

The PC doesn't recognize it at all, and the port is used for both the USB and Wall Charge.
So you assume that it is hardware malfunction, so would it be the ports fault or the battery with the wires connected to the motherboard's fault?

Could be either. The port itself is bad, or a connection to the port. Without opening it up, you wouldn't know. Either way, if its under warranty, I would return it,

Oh i opened it up before and checked, but i didn't unscrew the motherboard since the ports were upside down, so i couldn't check whether the port or the battery was wrong.
