Problem

The laptop power cable consists of two cables with a transformer in the middle. The transformer is making a tiny noise while plugged in. I think it's normal... is it normal? What is it exactly?

Fix for: Why is the laptop charger thing (transformer) making a noise?

Low Risk

It's a transformer. Not Optimus Prime, but a boring device that steps down mains voltage to the voltage your laptop requires. A slight hum is normal.
