Re: Lenovo Y540 crackling sound

2019-10-23, 4:10 AM

I was having the same issue too but it seems to have stopped after this fix.

Edit: The issue was fixed on my Y545 that I purchased about two months ago.

Second Edit: Before I discovered this new fix, I attempted berniwa's solution and it made the crackles slightly longer, but it occurred less often. I just changed the setting back, since I wasn't sure what else it would affect. After the fix, the crackle seems to still occur during startup, but I've yet to hear it during actual use.

Probably because features don't get removed once they're added to the BIOS (I'm not sure about this)? I distinctly remember not having the feature before 32WW.

After one week test I heard only two clicks, good enough for normal user, not enough for music composer/DJ. I'm wondering if anyone try to reduce slow slew rate in BIOS to Fast/4 or even Fast/2?

You actually have that option? On my 26WW there is just 8/16.

Yes, there are more options for 32WW, related thread here

https://forums.lenovo.com/t5/Gaming-Laptops/Y540-BIOS-update-question-32WW/td-p/4535243

I think reduce it would further reduce the click, but I don't know what is the trade-off.

I think it may be the Lenovo Vantage Service that is installed from the Lenovo Vantage app from the store. I think all of us installed to control the Performance level, but the services required to do this may be the problem here.

It is causing some wifi disconnections too ! Whenever I open the app the wifi disconnects and keeps disconnecting every 15 minutes or so until I reboot the laptop
