Went off while plugging usb

Hello,

today I was using my Macbook outside. It is about 35C outside, but I used my laptop online for about 15 minutes. I wanted to plug my camera wire but when I plugged the wire in Macbook died in a second I plugged it in. I thounght that it may be because of the battery, but when i plugged the battery wire in it still doesn't work. The green light on a battery is kind of blicking, that doens't normally happen. I thought that it may be overheated or something, but it is cooled down and still nothing happens. Not even the battery percentage on the left side of the Mac body doesn't work.I searched the internet and tried everything and still noving works My Macbook is pretty new, only about 5 months old. Thanks for help.
