My old tablet suddenly stopped responding to charging, even though everything was fine yesterday. I gave it to the specialists, and they found problems in the power board. It was possible to restore, and it was not so expensive. It's great that the device was checked for free, and then the exact price was announced. A day later, I picked up the tablet, and it charges again without any failures. As a bonus, they gave me a repair guarantee. I'm glad I didn't throw the device away in vain.
