@Linux_in_a_Bit @StarkRG yeah, for that room, but I doubt your bedroom has a dedicaded breaker on it's own.
- None of the places I lived in had that...
StarkRG@kkarhan @Linux_in_a_Bit It also isn't necessarily just your house. Industrial and commercial users are usually required to compensate for their own non-resistive loads, but that only matters if such regulation exists and is enforced with inspections and fines or shut-downs. That said, if it *was* caused by an external user, I'd expect you'd notice other things pushing it over the edge. My guess is that the charger is putting noise on the line, which it definitely should not be doing.
@kkarhan @Linux_in_a_Bit You might try getting a kill-a-watt (or similar) and checking the power factor. Ideally you want it to be 1, but within a few single digit percent is fine too.
You could try adding a ferrite bead to the AC side near the plug. That should reduce any high frequency noise, but I'm not sure if there's a specific type you should get.
@StarkRG @Linux_in_a_Bit either way this shouldn't happen with a laptop charger that is most likely ≤ 250W…
@kkarhan @Linux_in_a_Bit Oh, yeah, very much so. Either it's faulty or it was badly designed, both of which seem equally likely.
That said, my GPU also shouldn't be making an extremely high pitched whine during some graphical procedures, but it does and I can't be bothered at the moment to figure out which of its many capacitors is going bad. At some point I'll probably just have to replace them all. Or wait until it pops, then I'll definitely know which one it was.
@StarkRG @Linux_in_a_Bit #CoilWhine on #GPU's, espechally.in high framerates >480fps is sadly neither new nor uncommon…
@kkarhan @Linux_in_a_Bit Framerate doesn't seem to matter, and it only happens sometimes (I think decoding video is one of those times, another is when a game is done or almost done loading but the menu hasn't appeared yet, it rarely happens when rendering the actual game suggesting it's probably related to 2D operations). Anyway, my point was that, while it shouldn't be doing that, it's probably working well enough not to be worth doing anything about.
