T440s speaker noise

Hello!

 

I have following issue with my new T440s' speakers:

a) having generic audio driver, there is silent noise everytime some sound is played approx. for 5 seconds

b) having most recent Realtek there is permanent the same noise unless it is muted using Fn+F1. Only "software mute" doesn't work.

 

I have Windows 8.1 x64.

I tried some googled tips with disabling the microphone but none of them has worked.

 

This is very annoying, since there is SSD and ULV this is the only noise this laptop produce.

 

Thank you!

 

Drozi

Re: T440s speaker noise

I have exactly same problem.

 

However, I don't think that this is driver problem since this buzzing is heard even when laptop is in bios. From what I can tell, sound(buzzing) is comming directly from speakers.(both of them)

 

And you are right, it is extremly annoying and it is killing this otherwise very quiet laptop.

Re: T440s speaker noise

I have the same problem, too.

 

But the noise isn't always there... it may stop for a while, then return, contiue for a while, and stop again, and then return again, ... It is pretty annoying...

Have called and written to Lenovo customer-care, but got nothing. Via phone recomended to send an email. Via email no respond.

Re: T440s speaker noise

It is somewhat strange. I can hear the noise even with headset plugged in.

Re: T440s speaker noise

I'm thinking if this problem is only exist in several configurations. I have a i5 4300, 7260ac, ssd+16gb m.2. Could you guys provide the specification?

Re: T440s speaker noise

Have you guys updated the bios?

I have post a similar thread in a Chinese thinkpad forum, the only two person replied did not have the same problem.

Mine is i5 4200 and HDD. I searched a little bit online and saw people complain that T61 had already had this problem!

Re: T440s speaker noise

Update from Chinese forum, 3 out 5 have the same problem. This seems common for T440s. Anyone from Lenovo could raise this problem to the technician team?
