Battery not charging !!!. replacement of new batter also has the same problem. and old batter suddenly started charging by meddling with the cable for once. and then again the same problem. would it be mother board circuit or switch problem and if yes what is the best way to fix

Nextbook 8 NX785QC8G shutting down on its own FreakTab com

shaunmt might have answer

Read through the other threads here about the NX785QC8G. They all have problems with the battery connector. The cable comes loose from the socket, which leads to incorrect batter level monitoring, sudden shutdowns and improper or no battery charging.

You'll most likely have to remove the back of the tablet, unplug and firmly replug the batter cable and consider options to prevent the cable from pulling loose again.

IF you take it out and go to autozone or orielly etc they have a machine that can test it

If it is clicking then either the batter is still too low, or the ground or hot wires are loose as wellas a possible bad starter selenoid. check the battery condition and wires for tightness before replacing the selenoid.

Please compare the Volts AND Amp ratings on BOTH the laptop (underside) AND the A/C adapter.
IF they don't match, then battery may not charge to full capacity.

Example: 19V, 3.9Amp

Yes in some cases it can run off alternator but your car still need to be hooked up to the batter. In some other cases you still need some of a charge in the battery because your car is drawing more current than what your alternator puts out when starting. If the battery is more than 4 years old it might need to be replaced. Take it to a local auto parts store and have them test the batter if possible. If you are using a cheap small wired jumper cable it might not be allowing enough current to start the other car.

You probaly have a broken DC JACK on the motherboard. Therefore, regardless if you have a good power adapter. The power is not making a connetion to the battery because the DC JACK throught which the power flows is broken.

Try another adapter and remove the battery. If the computer is powered up using the new adapter then the old adapter is bad and the DC JACK is good. Replace the battery and if the batter charges, you can identify the old power adapter as the culprit. If the batter does not charge but the laptop powered on. Then both the battery and the charger is faulty-battery not holding charge.

Good luck

I had the same problem look a fuels next to the batter replace it , then you be good to goooooooooo.. good luck

You have low battery voltage. Normal 12volt batter should have almost 13 volts when fully charged. It's spring--check your battery cable ends / batter terminals. Got the white cancer growing? Remove and clean everything off and rinse with baking soda and water. Make the ends and terminals nice and shiny. Fully charge the battery and hook everything back up. To help stop the forming of the white cancer, use red/green felt pads or battery terminal spray. If your battery runs down again, take to NAPA and have them check your battery. If your battery is 5 years old or more you might need a new one.

sounds like you are putting a bad battery into the car...try a fresh battery.  Batter is spelled...battery

Boost your car with jumper cables and let the car idle or drive around for about 20 minutes for the alternather charge the batter on its own .if the car shuts off after you started it might be your alternather is no good . the reason why ur alternather might not be working is because the batter all it does is give enough power for the starter to crank the engine as soon as the engine starts running it gets all its juice from the alternather and it charges the batter as well. but some times when the alternather works and the batter is dead meaning all the cells inside the batter are dead it will never take the charge from the alternather. so you would have to change the batter.

if you would like to know how you can you test both parts useing a volt-a-meter... just ask...

p.s. I think its ur batter if you never changed it. so get that changed for the winter so you wont have any more starting problems during cold wheaters
