Weird PC troubleshooting question:
When I plug in my laptop's charger, the lights in my house start flickering irregularly (this is slight enough that other people don't notice it).
I unplug my laptop from the charger, and the flickering stops.
Then I plug the laptop back in, and the flickering doesn't return?
Why is this happening and is this a normal thing? 
@Linux_in_a_Bit USB-C? Your charger is probably struggling with the PD negotiation and making a high frequency switching loop. Your LEDs are sensitive to it. It probably all comes back to the charger capacitors not being full on the first go round. Not a problem.

Barrel jack.
I have a lamp with half LED half incandescent and it's affected too. Might just be the LED bulb, but idk.
It does come back after re-plugging, it just isn't as bad for a little bit.
@daniel
Nope, just LEDs are affected. hmm
@Linux_in_a_Bit re-plugging like you’re doing will be better for the charger and your lights.
