I have a tablet that wont turn on. It shows a dead battery sign with an exclamation point inside of the battery.

To view your password you need to open up a command prompt (cmd.exe)

Than type in netsh wlan show profile and press enter. This command will show all of the access point you have connected to in the past

Now type in netsh wlan show profile "your access point SSID without the quote" key=clear and press Enter

example if my SSID is ABCD than I would type it like this

netsh wlan show profile ABCD key=clear

It will show you the password of your access point.

That symbol usually indicates the battery isn't charged or charging. It could be a connection problem, a charger problem, or a battery problem.

If you have an extra wall charger, try that first as they don't always last forever. Make sure the plug that connects to your tablet looks clean and not corroded.

If it still won't charge, then chances are the battery needs servicing to make sure the connection is OK or the battery just might need to be replaced.

Check the output of the charger to make sure its actually working, if it is most likely the battery connector inside the unit is bad, or the battery is bad.

Check its charger. If the charger is faulty, it won't charge the battery. If it is found OK, replace the battery. It is bad.

Can mean the battery isn't communicating its status to the tablet--failing battery, bad connection, etc. Talk to tech support for a replacement if it's still under warranty. If it's not and you can still charge it to 100%, hang on and hope for the best.

The battery is dead and cannot be recharged. Replace the battery.

A triangle with an ! in it usually means that it's operating system has been rooted. Is it second hand if so the previous owner has been playing around with it and the warranty is void.It can be wiped and reinstalled, but you need to know what you are doing, there are instructions and videos on u tube showing how it's done.

my ipad wont turn on it like when you press the home button it lights but you cant see a thing I don't know what to do with it it wont come on if you have a answer to this problem please I need your answer right away. Thanks

I had this same thing. The Batter image had a red line on the right side and the yellow triangle had an explanation point in the middle.

I searched the net and found a few solutions.

1. Hold the power button down for 30 seconds.

2. Hold the power button down and the volume down button at the same time for 30 seconds.

3. Just let it charge and over night and it should go back to normal.

I did all 3, in the order I wrote them. While in step 3, after about 5 minutes I pressed the power button and it showed that it was charging normal.

Hope this helps.

The exclamation mark means that your tablet has no battery left. You should try plugging your tablet in for a few hours before turning it on (if it doesn't turn on by itself.) If that doesn't work and you still see the exclamation mark, I suggest that you ensure the charger is properly plugged in to the socket and that its properly attached to the tablet.
