gollark: I heard a "pop" noise earlier today when using my laptop (Legion 5, 2020, RTX 2060, i5-10300H), and it seems that now heavy GPU load causes a weird periodic buzzing noise (attached; sorry for the poor quality but I had to boost the volume lots for it to be audible, and also the recording is mostly fan noise). I figure it's a GPU power supply issue.
gollark: Discrete = always use dedicated GPU, dynamic = sometimes use integrated GPU, probably.
gollark: It's running but ÆÆÆÆÆ IPv6 configuration.
