Will the tablet operate on the docking station (or power cord) without the battery in place?

If not, the power circuit on the tablet motherboard is broken.

Can I buy a power cord that charges while you are using the tablet?


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.

How can I change the battery in m9100 kocaso


Try the follow to see if it will fix it:
There is a power reset button near the charging port. It looks like a tiny hole. While plugged into the charger, use a paperclip to push the button inside this hole for 3-5 seconds. If it turns on, please allow it to charge for 4-6 hours before using it. If you leave it on the charger for longer than the allocated time, you will go back to having the same problem as before. If the power does not come on, please leave it plugged up for 4-6 hours then disconnect it from the power and turn it on.

If your tablet does not have the reset button: With the tablet plugged into the charger, hold the power button for 10 seconds then click the volume up once. If it turns on, please allow it to charge for 4-6 hours before using it. If you leave it on the charger for longer than the allocated time, you will go back to having the same problem as before. If the power does not come on, please leave it plugged up for 4-6 hours then disconnect it from the power and turn it on.

After performing the power reset on the device the device will behave in one of the following ways:
1. The tablet will turn on like normal.
2. The tablet will show the battery icon only.
3. The tablet will show nothing on the screen at all.

All of these are normal for the device and should not be cause for alarm. If the device still fails to power on after being left on the charger for 4-6 hours,

Then most likely the battery will need replacing.

I have the Trio 7" Dual core tablet. The battery is not charging completely, can this battery be replaced and if so where do I find the battery in the unit?


Battery replacement is possible. The battery is a flat component encased in a shiny silvery sheath behind the speaker area inside the back cover. It's mounted with double-sided (very) sticky-tape. A replacemnent battery should be sourced, having the same power specifications as well as physical dimensions. (see detailed close-up photo attached.) Replacement involves desoldering the 2 terminal wires (1 red and 1 black) which attach it to the main board, and replacing the battery with a new(er) unit.
The above having been said,I'd only replace the tablet battery if I was sure that it's the battery at fault. Here's what I'd suggest.
First, check that you're using a charger with the proper 5 Volt / 2Amp (2000milliamp) output. Also I'd suggest you use a charger designed to be plugged intothe G2 7" Dual-Core tablet's dedicated charging port. (See sample tablet charger in attached photo) The G2 tablets WILL typically accept charging output via the micro USB port, for example, from a typical cell phone charger. However typical phone chargers which will happily attach to the Trio or other similar tablets, via the micro-USB port do NOT often have the same output power specifications. This I think may cause difficulty with the tablet battery not reaching the fully-charged status. Also, the use of the USB port for charging may cause access problems if the battery power is low during some operations (eg data transfer in slave mode), as the charging port can not multitask as the USB port can. If power to the main boad is lost during such operations the tablet may become "bricked". Bottom line for me would be to use the dedicated appropriately rated charger whenever possible: it's the reccommended charging method.

I have a nextbook 7P12 and it won't turn on. I have charged it as I thought the battery was flat. Now it won't turn on and I'm stuck as what to do. Anyone know how to fix it? Thanks


The Nextbook tablet can be turned on by pushing down the volume button and the power on and off button at the same time, hold down a few seconds and wait. It should turn on again. It always works for me.
