My flip mino hd is bricked

I was just recording when after i ended the video (34 secs) it did not turn on, neither did my computer (windows 10) respond to it. it will light up but nothing happens on screen. i’ve tried resetting it, but nothing works. it is just a brick at this point. I really dont want to get another one because the files will be gone and it would be expensive. so is this a battery, power button, Usb, or the entire thing’s problem
