Need help with Mac

I have a 2015 MacBook Pro 13 inch retina screen and I bought it brand new and never touched it and now when I decided that it’s time to use it I bought a MagSafe charger and plugged it in, the light turned orange showing that it’s charging. I’ve been charging it for 24 hours now and when I try to turn it on it shows that it’s still dead and needs to charge. Any fixes?
