Two Saturdays ago was “yard sale day,” and my Mom, my little sister Sophie, and Johanna went garage sailing with my friend Adrian’s family, and one of the things that Adrian got was a free hoverboard. I had assumed that this hoverboard was broken, so I asked if I could borrow it to try to fix it. And Adrian had agreed, so later that night, I began taking the hoverboard apart. I had checked the battery level with a power level indicator, and it had said that it was full, so I realized that the problem is between the power switch and the battery. And my brother Gideon found out the problem. It was that the power box cable wasn’t plugged in. Once I plugged it in, the hoverboard turned on! I reassembled the hoverboard and took it outside, but it kept beeping with a red light when I turned it on. After a bit of googling, I found a video showing how to reset the hoverboard. I tried it, and it worked! I gave it back to Adrian the next day.
