How do you replace a bad battery in a Colby model MP977 Vzone tablet?

possible bad battery.

All rechargeable batteries will eventually fail to take and/or hold a charge. In some cases it is due to being worn out, in others it is due to what is called "battery memory". Battery Memory occurs when a battery is charged often, but is not allowed to fully discharge between chargings. It was really bad with the old Ni-Cad type batteries, but all batteries can have some affects.

I have seen these problems on such devices... It almost always is that the battery. Check the voltage going to the battery and the voltage in the battery itself.

Are you actually turning the tablet off when you are not using it? (Hold down power button until Power Off box appears on screen)? If not, your tablet is constantly using power even with the screen blanked and will drain the battery. You could have a bad battery that is no longer holding its charge. How long can you run the device off the charger continuously? That length of time might indicate the state of the battery. Check the manual for expected battery life, which for a Linx 7 is usually 4 hours or less.

Sounds like you have a bad battery or your charger isn't working.

both of my charging ports are bad , thats your problem also, we need to find a supplier for the parts so they can be fixed..

Sounds like it does not have enough battery power to stay on. If you have not tried to charge it, you should try that first. If you have, it sounds like it is not getting charged or not holding a charge. Could be bad AC power source, bad charger, bad charger connection or bad battery. Take steps to confirm that each of these are good. If all of these are good, sometimes the tablet can become so discharged that it will not allow itself to charge. When they are in that state, sometimes you can trick them into charging again by repeatedly disconnecting and reconnecting the charger as follows: With charger plugged in to AC power source, connect the charger to the tablet. Pay attention to the screen or LED or whatever indicator your tablet has to let you know it is charging. You may see it momentarily indicate charging, or maybe not at all. Then unplug the charger from the tablet then immediately plug it back in and pay attention for the charge indication again. You may have to do this a bunch of times (like 20) until you see the indication that it is charging. When you do get the indication, stop unplugging and re-plugging and let the tablet charge for 24 hours (to a full charge). This trick doesn't always work. Sometimes the battery or charging circuit or an internal connection is bad and no amount of unplugging/re-plugging will fix a hardware problem.

just google it many wideos on it.

I have the matsunichi 9.7 my email has amessage saying connection problem no emails has come in for 2 days. What can i do to fix the problem

Is your battery removable? Try removing the battery and then plugging in the tablet. If the tablet runs on only the AC power, then your battery is shot.
