Will not turn on,will turn on without charger in it

if it is not the same brand chrger that u had frst then it wont work, if u buy the same brand then it will work, sorry about that

Try a reboot of the kindle
Take off any cover you may have on the kindle and disconnect it from any outside sources like a computer
Initially connect the kindle to the charger and then hold down the on/off (or slide to the right) switch for more than 20 seconds or until you see the screen flicker on the kindle then release the button, the kindle should reload the operating system between (1 and 3 mins)and all should be well after this
If this does not work try same procedure without the charger.....if this does not work try this.....This time hold the switch down (or to the right)until you see the screen flicker, then wait up to 3 mins for the operating system to reload.
The problem you have is the firmware has crashed thats why its locked up
Do it with the charger first then if necessary without the charger

(This is what i just found on the internet)

It sounds like your battery is dying. I would suggest buying a new one. We can help you find, on Amazon, what you need if you tell us exactly what netbook you have.

Feel your chrger, Is it warm to the touch? If it isnt, you may need to replace it. Can you turn the tablet turn off and can you turn it back on? What is the level of the battery?1/2, 3/4?

Dodgy wires I would guess. Get a new connector lead.

It sounds like there's a problem with the charger. The wire on the charger is rather delicate. So is the port on your tablet where the wire plugs in. There may be a break inside the wire. If you dropped your tablet while the wire was plugged in and it hit the floor on the charger plug, the charger plug could have damaged the charging port in the tablet or the wire itself could be damaged.
Find someone else who has the same tablet and ask to switch chargers to see if either of them still work on the other tablet. If your friend's charger starts charging your tablet without a problem, then the problem is a a broken wire in your charger. If neither charger will charge your tablet but both chargers charge your friends tablet without a problem, then the problem is with the charging port on your tablet.

If it just stopped charging and you have tried other chrgers, then the probable cause would be the battery for the tablet has failed. This is fairly common and would require disassembly of the tablet and replacement of the battery to fix.

Most likely the charger is not functioning. Test it with a meter where it goes into USB port and plugged into wall outlet.

The only way i know of is to take off the back casing and look at where the the charger port is and you might be able to remove it with an object a little bit bigger than the end of the charger. otherwise you cant do it your self withput messing something up on the tablet.

The charger has a function that restores the battery operation parameters by discharging then charging the battery a number of times. Refer to charging instructions in the pack but I think the cycle is a 3 hourly one, time to charge from a full discharge. If the charger thinks the battery is dead then it will try to recover the battery using this process. You may have left the charger on long enough to charge then also discharge the battery.
Start again and charge for the time in the instructions ONLY, if you are not sure of the time try it for an hour, then without disconnecting the charger turn the unit on and take particular note of any screen messages, if any.
You should be able to continue as normal now, but still be aware of the time you are leaving the charger connected for, as it may take some time before it returns to normal operation and stops trying to recover what it thinks is a dead battery.
