If your tablet will not turn on, the battery may need to be charged. You should connect a charging cable to your device and wait a few hours, then try to turn it on again.

The problem may be the power button. If your device is able to charge but still doesn’t respond to the power button, the problem is likely the power button. Note that if you want to replace the power button, you have to replace the motherboard.

The problem can also in your power adapter. Try to use your power adapter with other devices, and see if it can charge them. If your power adapter does not charge other devices, you should try using a different adapter.

If the original power adapter can charge other devices, the problem may be your charging port. You can follow this this guide to replace your charging port.

The device is docked to a keyboard or other attachment, but the attached device does not work properly.

The first thing you should do is check if the docking port needs to be cleaned. You can clean your docking port with a needle or a toothpick. Be careful not to damage the connectors in the port while you are cleaning it.

If the port appears clean, the problem may be the attached device. You can find out more by docking other attachments and seeing if they work. If other devices work, it may be the original attached device having problems.

If the port still will not work, you can try replacing the port itself as shown in this guide.
