No, do not connect Ethernet during hardware upgrades.
No, do not connect Ethernet during hardware upgrades.
Depends what you're doing, but I unplug it all when upgrading usually. For RAM, I just do power. But for other stuff I unplug all the mouse, keyboard, speakers, etc and put the PC on my coffee table and watch TV and mess with it. No hurry in my house. Ethernet isn't called LOW VOLTAGE for no reason
It doesn't really matter; Ethernet remains separate. The connection between the cable and your computer's parts is essentially nonexistent.
It’s not always necessary to disconnect the power cable for everything. Doing so helps prevent accidental activation and keeps systems in a stable state. Removing the plug simplifies troubleshooting and maintenance. However, leaving devices connected can still pose risks depending on the setup.
Additionally, turning off the power switch on the supply and keeping the power cord connected helps maintain grounding.
Do not keep the PSU linked and running. It might accidentally create a short on the standby 5V line, risking damage. If there’s a switch, turn it off. Keep it connected to maintain a solid ground connection and prevent static harm.
Except for a light source passing through the wire, everything should be okay.
