Battery/Connections problem, not starting?

Hi, first post on here, and I'm pretty green to motorcycles too, so if you can help me out, I'd really appreciate it
But for the first time today when I went to start my bike for a morning ride, the engine never started, or made the regular sound it would. instead it just made a buzzing sound, coming from the battery, and I have no idea what to do about it. I don't want to take my bike apart, but I really want to get it fixed ASAP
Please help!!

Try charging the battery first. If that fails replace the thing.

Could just be a loose connection on the battery terminal, have a look and tighten it up.

Battery is dead.

Time for a newy or at least check the voltage for the old one

the cold weather seems to be killing a few battery's.

yes - every year its the same. Its been this way since Gaston Plante first dropped some lead plates into a solution of sulphuric acid......or something.
