The motherboard does’t manage the power so, my tablet doesn’t charge. What can i do and is it worth to repair it?

@goncalot3 not exactly sure what you mean by “motherboard does’t manage the power” If you are saying it does not charge you should at first test things like the charger itself, the cable you are suing and check your charging port. If that is okay then you want to do a deep dive into the board situation. For that you will have to properly identify your device since I do believe that the Nexus 7 is not ASUS but a Google product. your question about is it worth to repair it will depend on your abilities, your financial situation and if it means anything to you. My take on this is that yes, it absolutely is worth a repair
