Do you really have to wait 10 whole seconds when rebooting your device?

We’re supposed to wait a grueling 10 seconds when rebooting a router or device. Is it really necessary? 

Yes. Tech experts explain it’s all about capacitors. They are small batteries that live in your device and they fill with energy while the power is on. After unplugging or powering down your router, computer or device, you need to wait at least 10 seconds for that capacitor to fully discharge. Larger capacitors could take as long as 30 seconds to fully discharge, so your best bet is to follow the instructions provided with the equipment or by your IT support.
