Bike won't turn on. Any troubleshooting?

[D C]

So, here I am at the office without my charger, and my bike won't turn on. When I parked it this morning, it had about 50% charge left on the battery. I can't think of a reason why the battery would be dead. But when I press the power button, or hold it down, absolutely nothing happens.

Any troubleshooting I can do here, or do I need to take it home and try charging it?

It's a 2016 Specialized Turbo S.

Remove the battery and restart.
Hopefully, it's a loose connection.
Few times, I have lost 30% capacity just because of cold temperatures.

I think the procedure is to remove the battery, turn it on and when it turns off, put it back on to the bike.

Definitely remove the battery. Try it on the charger off the bike. Should light up with 3 flashing lights if at 50% - 75%.

The shop is replacing the battery.
