Toshiba A205-S4607 freezes immediately charger is plugged in

I got a better theory when you plugged the nextbook into the wrong charger it shorted out the circuit board an cooked it get a new one and a proper charger ......Good Luck

If the tablet works while plugged-in to the charger, yet dies immediately when the charger is disconnected, it means that the rechargeable battery in the tablet is dead.
If the unit will not turn on at all, even with the charger attached, the charger itself may have failed, or the unit may be having other issues.

Check the charger first. Plug it into something else. See if it charges. If you can not do that take it to a store like best buy and see if the have a replacement charger that you can try. The plug in the tablet can come loose if it is dropped while plugged in and if that happens you are in the market for a new one.

Hi
I don't know what connectors you have on your tablet, but often there is a micro USB socket for connecting a lead from there to a standard USB socket on a computer. Some devices can also charge through this connection, so this is worth a try.
You may also try replacing the charger with a new one, in case yours has become faulty (you could check for a voltage at the plug for the tablet when the charger is plugged in by using a suitable multimeter on the right setting. Absence of voltage here would confirm a faulty charger.)
Otherwise, if the charger is OK and all the connections are firm and good, it may be necessary to replace the battery as rechargeable batteries do have a finite life.
Hope this is helpful, if so would you please register that with Fixya
Cheers

get a new charger

Try performing a power reset. There should 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.

It has a non removable battery. :)
It's using a proprietary plug that most probably be defective or faulty. Get another cable for that and see if it works.

Try removing the battery and see if it will boot without it
Then check the caharger, charging light should be green and steady on the charger itself
If it is flickering, it meand power is not making a circuit, test charger jack with a DC volt multimeter with one probe to the outer side (earth) and one on the inner (positive). If this is ok, check the charging socket is not loose (if it is, will need replacing).

After that, suspect the power strip or charging / powerboard is dead on the motherboard

You will need to purchase a new Power Supply Unit if it is not able to start up when it is plugged in the PSU is bad. Replace the unit immediately. I hope this assisted you. You can find them reasonable at Amazon.com this is where I purchase customers units at. Thanks for using FixYa for all you questions. John
