I'm so sorry you're having this issue. One of the only ways to fix this problem with this tablet is to replace the internal guts of it, which includes the battery. We have some very nice guides on the matter written on the device's page. Hope this helps!

We've covered this to a degree in our troubleshooting page, but there are many possibilities. Most of them will end up coming back to a motherboard issue if the tablet freezes consistently. If it just happens occasionally, but only when using the same program, you may need to try reinstalling the program or using a different one.

Great question. We've got a few of the possibilities listed on the device's troubleshooting page, but I'll go over a couple here. Make sure that your device's power button is pressing correctly. If it seems sticky or doesn't move, you may need to open up the device and re-seat it. If that's not the issue, make sure that lights are turning on when you attempt to turn on the device. If they are turning on but your screen isn't, your device's motherboard or LCD may be going bad. If no lights turn on, likely your battery has gone bad or won't hold a charge.
