Strange Sound When Plugged In

[past tusk]

Model: Legion Slim 5, Ryzen 7 8845HS, RTX 4070
Issue: A strange clicking sound happens only when plugged in, and only when in a game.
I have already tried opening the laptop up and looking for anything suspicious, but all screws seem ok and the fans were not the source of the noise.
This issue started the day I got the computer (5 days ago).
I have not installed any new drivers.
Attached is a video (headphones needed to hear the clicking).

thats coil whine. nothing you can do about it

Since it's new, best to apply for warranty.

Coil whine isn’t an issue and a new motherboard wouldn’t necessarily change anything. Also Lenovo techs would ruin the stock cooling. Using warranty for this is a poor idea

agreed this is coil whine, won't be solved by warranty

normal noise in the slim 5

how loud the whine is can depend on the current BIOS. what's your current BIOS version?

don't update BIOS yet, i wanna know the version first

Hi, thanks for your replies! My current BIOS version is NRCN17WW

do you think it'd be feasible to tweak some settings so that the GPU runs similarly plugged in to how to how it runs on battery? A bit less performance but then I wouldn't hear the whine

[junior canopy]

is the whine even audible when the game is playing audio over speakers/headphones?

or over laptop fans

you can configure the GPU similarly to how it runs on battery, or heck to how it runs when a game isn't running. by turning the GPU off with hybrid-iGPU mode

if the game's system requirements are low you genuinely might be able to get away with running the game on the iGPU

it's drowned out by the speakers pretty easily, but if you put your ear to the laptop you can still hear it a bit
