It could be two things, Jack: I would start by plugging it in to your charger for about 24 hrs to make sure it's not just the battery after that length of time not being used...OR, you might have to reset it to factory settings.
In the case of password lockouts or freezing, doing a hard reset on your android device could help you get back to the factory defaults.
First you need to make sure your tablet is powered off.
Hold down on the Volume + button and hold down the Power button at the same time.

• As soon as the tablet's screen turns on, let go of the Power button but keep the Volume + button held down until you see a large Android in the center of the screen.
• At this point you will see a screen with boot options.

• On the next screen use the Volume - button again to go down to Yes and use the Power button to select.
• At this point it will be going through the wiping and resetting process.
• When it's done you will see the first screen you came to when you first started the setup.

Many people say to push and hold down the Volume(+) and Power button at the same time. Push and hold for as long as twenty seconds until you see a green android with green text.

But, on some devices and some Android O/S versions it takes pushing and holding the Volume(-) and Power button and holding them both down for twenty seconds or so or until you see the green Android and text screen. This will show the Wipe Data/Factory reset option. Select this option by scrolling using the Volume(+) button and engage using the power button. Some devices give you a second screen with a list of *no no no no no* and one line of Factory Reset. Again, scroll to the Reset option using the Volume(+) option and select it using the power button.

If the above doesn't work, either your battery is dead or your device is dead.
