T6i receiving no power at all with fully charged battery

One day probably after a week after not using my camera, I decide to go out and take some pictures with friends. I charged the battery until it's full and once I insert the battery inside the camera, the red light would not even turn on. I know it's not the battery. I have a friend with the exact same camera and my battery works for his camera. I also tried his battery which also does not work on my camera. I tried switching the memory card, battery and lens. I also tried removing the lens and memory card but just with the battery inside. My camera did not get wet and the battery is fine. I'll put in a battery and no light would show up, nothing.
