some coil whine
What on Earth is Dell doing such that this has been a “feature” of the last 3(!) XPS 13 laptops I’ve owned? The internets are full of people complaining about this too. It’s like Dell tests these things in a loud lab environment, and QA can’t hear the coil whine when they give their check of approval. I honestly can’t think of any other reason why this problem would continue to exist for multiple laptop products/generations from Dell.
Good video about coil whine, tl;dr the type of inductor that’s more compact and better electrically is the one that is whiny, and modern silicon (GPU especially) does very aggressive power management to deliver good efficiency, so the load varies with very high frequencies, and vibrating the inductors at higher frequencies sounds more whiny.
that’s fantastic, thanks for the explanation!
Yep, I’m also a bit puzzled. but on the other hand maybe if it only comes up like every 200 units (I bet Dell sells thousands of these per month) and QA tested like 400 and only had 1 occurrence… Who knows?
I had a razer blade stealth with an nVidia MX150. It was great, until I heard so much coil whine I thought it was broken. I sent it in for repairs and got a replacement. It had coil whine and a bad wireless setup that would just drop connections under heavy load. Now I’m on my third and I consider myself lucky to only experience a little coil whine.
It seems to be a “feature” of modern laptops. Colleague bought a top-of-the-line MacBook a year or two ago which had terrible coil whine. He sent it back IIRC.
My ThinkPad T14 AMD does not have coil whine. Also didn’t experience it on any MacBook.
My GPU whines loudly when training a neural network. But it has the benefit that I can hear that training is still proceeding. If you listen carefully, you can also hear the difference between training and validation epochs.
Still has a 16:9 display, I see. If you’re using an external monitor that’s not an issue I guess. 16:9 might be ok for movies and games but in terms of productivity I find 16:10, 4:3, 3:2 all better aspect ratios.
I used to be a huge fan of 4:3 (especially on those juicy 1600x1200 22” iiyama or Eizo sceens) but these days I honestly don’t really care anymore. As I wrote, I would’ve chosen a 15” because the laptop is on my side so stuff could be a little bigger. :)
