Change battery work for a hour all so die and wont start backup again

it's a factory thing, all You need to do, is open your tab, remove the battery cable for about 10 mins and plug it back again, unplug the screen from the motherboard, and charge it for about, two hours, then plug back the screen connector, and turn it on, if you see it works, turn off the tablet again, and plug in the power cord again, you'll see the charging animation starts, leave it charging for the time you think it's necessary to reach 100%, unplug the cable and turn it on, your tablet is alive, the only problem I've found about this, is that you'll need to turn the tablet completely off whenever you want to charge it, and finally this, VERY IMPORTANT! When your tablet is below 15 or 10% battery, charge it, because if you let the battery die, probably you'll have to do all the steps again.

Help My tablet won turn on what do do

Why Does My Android Phone or Tablet Not Turn On

Sounds like maybe the battery is going bad. You can check on "you tube" for videos on how to change the battery. They usually show you where to purchase a replacement battery also. It really isn't that hard to do.

Lithium ION batteries are usually rechargeable. The use mode for these batteries is that there are a set number of recharges that equate to the life of the battery. Usually that life is approximately 1,000 charges.
If you use your battery to 50% then recharge, you can do this ~2,000 times. As the life of the battery is used up, the maximum charge lessens which means where you may have had 8 hours of play time when the battery was new, you will only have 6 hours as the battery life is used up.
In order for a Lithium ION battery to recharge there must be at least a small amount of charge left as a "seed" for that recharge. If you drain a L-ION battery down to zero, it may never recharge again or the max charge will be reduced to an insignificant amount of the original full charge. eg instead of 8 hours you may only get 15 minutes, or 5 minutes, or no minutes.
You are much better off recharging when 50% depleted than using it up til your product stops.
L-ION batteries cannot be repaired only replaced. Most cheap products using L-ION batteries cannot have their batteries replaced.

First - let it charge for an hour before continuing. Some tablets require that you hold the "On" button for 2 seconds to turn it on.

As soon as your iPad starts acting strange, it is time for a reset.

you can do this by simply closing all running apps. Press the home button twice and then swipe all apps up. They are closed then.
If all apps are closed, press the on / off button and keep it pressed till it says swipe to shut down. Swipe and wait till everything is out.
Then press the on / off button again, for a second or so. The iPad starts again.
Somewhat drastic, if you can't switch it of the normal way: Press and hold both, the on / off button and the home button, till the screen goes dark.Then the apple loge appears and again wait till the screen is dark. After that you can switch on again.
If it still does not work, goto settings then general then scroll to the bottom, where it says reset. then reset network settings. It will reset your network settings, but also the rest of the iPad. This is the most dramatic reset, without loosing your apps and documents.
One step further will wipe your data too, so that you must keep for the worst case and only after you are sure you have a backup on your computer from all your data.
Apps can be restored from the App store for free, if you have payed for them, but the data, unless you have backups, will be lost fro ever.

Have you tried a different charging cable?

Did you allow the battery to run down until it was completely drained?
- If so then try the following;

Watch this video (link below). You should only remove the back cover, disconnect and reconnect battery cable. Disregard the rest of the video as I could not find one doing ONLY what you would need to do. Follow the instructions to remove the back of the tablet then disconnect the battery cable(careful not to damage the circuit board), reconnect the battery cable, and replace the back cover. Connect the charger, within a minute the screen on the tablet will pulse/flicker which is good news, allow it to charge a while, turn on the device, turn off the wireless wifi, click the power button to turn the screen dark again, and allow to charge for another 6 hours or till fully charged (when not connected to wifi the background processes will affect the charge time, on a weak charger it may not even charge like from an usb port on a computer).

Again, you should only be concerned with the video up to about the 1 minute and 15 second mark. You only need to disconnect the cable then reattach it. ONLY DO SO if you are comfortable doing so. If you have never worked on electronics before or are uncomfortable find someone to do it for you.

your best bet is to backup your actual data on the tablet. Then do a fresh install (formating the drive) instead of repairing. This should let the install go through 100%. If it doesnt then i would look into it being a HD issue. But its better to do the fresh install first. Usually does the trick
