macbook pro is not powering up

macbook pro 15 late 2015 model is not powering up

Have you tried all the startup key combinations?

Startup key combinations for Mac - Apple Support

By not "powering up" do you mean that nothing happens when you depress the power button, or that it powers-on but does not boot up to the macOS Desktop? If the latter, at which point does it stop?

Nothing happens when I depress the power button. The battery is showing that it is 50% charged

I am trying these startup options, will advise after I have completed the options.
