How to take clear picture with carema on tablet

try to type in google in the browser bar to get it back or you will have to go in setting and factory reset the tablet

Yes you just need one of these:

No. HDMI ports are only data ports. There is no power routed through them as there is in USB ports.

If it's still on warranty, return it to the shop where you bought it for service.
Maybe it's just the battery? Get it checked but if not on warranty, I'm afraid that to repair it might cost you more then it's value. You can buy this tablet for about 50$ so you should ask how much might cost to repair it.

You must then do a factory reset using the Power and Volume

The model number is not the same but it should work anyhow.

There is a typo in Step 1, however so do this instead:

With the tablet turned OFF (not sleep but OFF) press and hold down at the same time both the Volume(-) button and the Power button. Continue to hold both of them down until you get a screen with the Android Robot, and or green text. That should set you up to follow the instructions.

Good luck.
