New BIOS updates for Razer Blade 14 and Blade Stealth address coil whine issues

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 (opens in new tab) 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) (opens in new tab) and Blad Stealth (opens in new tab) at Razer's support site.

  • I bought a Razer Keybard, the Deathstalker Chroma, that had this issue.  When you would display certain colors on the keyboard you would hear the whine.  Maybe they've been able to fix that as well if they were able to fix it in their laptops.  THough maybe coil whine caused by their led backlights can't be fixed in the same way.
  • Only for the late 2016? I've also noticed some coil whine on my 2017 model
  • Nice! I been wanting a new Razer Blade 14, but been on the fence because of reported quality issues by some. This might have just sold me on a Blade 14 for next month if the Lenovo 720 with 4K and the 1050 doesn't pan out with 4 PCIe lanes on the thunderbolt 3 port. Good to see a company like Razer listening to their customers.
  • Well, I installed the BIOS update and maybe the coil whine (electronic interference/resonance noise) is a bit quieter, but it's still there.  To be honest, it doesn't really bother me, it's very quiet compared to the noise of a Multiface Two on an Amstrad CPC, or... you know... the Razer fan noise problem. Now I am left wondering whether the update has decreased system performance.  
  • Halo Wars 2 seems to run as well as before.  Not very scientific, but performance seems unaffected.
