If you happen to own a Razer Blade 14 (late-2016) or Razer Blade Stealth, you'll want to pick up a new set of BIOS updates that address a particularly annoying problem: coil whine. Razer recently released the separate BIOS updates for both devices, and they seem to have done the trick according to several Reddit users.

Razer BIOS Updater

The issue in question is a whining noise that would emanate from some Blade and Blade Stealth laptops when under stress. It's not clear what the exact cause of the issue was, but the BIOS update seems to have solved the problem. While the problem wasn't present for everyone, there isn't any harm in installing the update for those who unaffected.

If you own one other above laptops, you should be able to grab the latest BIOS update through your Razer Updater. Alternatively, you can grab the updates separately for the Blade 14 (late-2016) and Blad Stealth at Razer's support site.
