Lenovo IdeaPad 3 Won't Boot or Power On – Any Suggestions?

I came home to find my Lenovo IdeaPad 3, which was at 13% battery this morning, completely dead. I tried plugging it in to charge while I was out, but when I got back, it wouldn't turn on at all. I've attempted to drain residual energy and boot it without the battery connected, plus I checked the charger with a multimeter, and that seems to be working fine. There are no lights on the laptop, no noises—it's like a brick at this point. There's no visible physical damage either. What else can I try to get it working? I'm feeling pretty lost here.
