Re: After runnig on battery power it powers off
Obviously its a battery problem
Usually happens on old batteries.
A new replacement will fix this problem.
Usually a healthy baterry should last between 1 to 2 hours...some models even give you 4 hours working time.

Is the battery status low or decreasing very rapidly (activate percentage display for the battery) then it could be your battery is worn out. It can cause the iPad to shut off or reboot when the battery can't deliver the required power anymore. Like when you run a power intensive task the power drain is too much for the battery and it can't keep the required voltage.
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.
To reset it just hold the power button for 20 seconds, If your Kindle Fire won't turn on it's possible the battery went dead (if it was left "on" too long).
Plug in the power charger and wait about 15 minutes to make sure it gets enough charge, and then try turning it on again.
If it still won't turn on, try to reset the Kindle Fire again to be sure it's powered off. hope that helps
Hi, Remove the adapter and the battery from the laptop.
Press the power button and hold it down for 20 seconds(without the
battery or adapter plugged in to it). This process is called POWER
Now connect only the adapter and try to turn it on.
If it starts up, there is no problem with the adapter or the laptop.
If it doesn't, it can be either the adapter or the laptop.
You will have to check it with a different adapter to confirm which one is faulty.
The second case is that the computer powers on only with the adapter.
Then you can put the battery back in and try powering it up.
If it doesn't work, try connecting the adapter too.
If still it doesn't work, its a faulty battery.
Sometimes after doing a power drain, the computer will work fine.
If you have any more issues, feel free to contact me.
