Electrical appliances, especially the order of laptops, adapters and sockets

Answer:

First plug the plug, and then plug the computer head, because the laptop power adapter principle: AC plug - "to the adapter after the change (the general transformer only after a dozen to twenty volts) and then output to the computer, Security and security of the computer are no danger.

I made the factory in Taiwan fnshion adapter factory in Suzhou, the factory test requirements are: boot the first insert the notebook, then plug the socket, so that you can determine whether the adapter can boot with the boot, to understand its stability; the second is to avoid the plug charged plug , The public seat and the mother of the tip discharge, resulting in plug melting; pull out when the first socket, then pull the notebook. Most people I do not tell him, haha, give the best! PS: fnshion adapter has a high-grade ultra-thin black, with a button switch function, you can not directly pull the socket on the key off / boot switch, so that pull out the trouble, most people can not remember the order!

First plug the power adapter into the socket and then connect the computer, give the computer boot, pull out when the first shutdown, and then plug out the plug on the computer, and finally the adapter plug

Usually first connected to the computer, and then insert the power supply, because the circuit closed in the fit, there will be put in the closing point of the phenomenon, easy to destroy the corresponding electrical components. And the power adapter circuit connected to the computer, then suddenly insert the circuit, likely to cause instantaneous high current, there is a chance to damage the adapter. Similarly, pull out the order, first unplug the power, and then unplug the adapter on it. Note: Now the circuit is relatively safe and stable, the general order has no effect.

Connect the power adapter to the computer first. Then insert the socket. If not so. First plug in the socket, then access the computer. Will let the power adapter to the computer that jack sparks. The Over time will be a problem. So remember not to get back. Pull out on the contrary. First pull the socket. The Pull the computer.
