Re: W540 Speaker hissing sound

2014-03-04, 10:39 AM

I think the most important point for all to note is that the situation has been recognized and is being worked on as reported by Mark in the T440s thread.

Hi andyP,

 

Thanks for the headsup.  In the end, the only thing that I (and I believe the same goes for everyone else) care about is that Lenovo acknowledges problems and commits to investigating them.

 

I would also like to note that there seems to be two completely separate issues regarding speaker noise.  One seems to be related to the dock and electrical interference.  The other is a hissing sound which is very similar to the sound you get when you crank up the volume for any given speakers and don't play any sound.  This thread and the link to the T440s thread that I posted pertains to the latter issue.

 

Thanks!

I think the cranking up of the speaker is a good example of the issue here. That sound is there even in the lowest volume setting, yet goes away when muted. My W550s that just came in the mail has this very same issue, however, it is odd that they would be using the same speaker piece that had issues in the past models. I hope this is sorted out soon...

The same issue is happening to all newly bought 2015 Thinkpad T550 as well. This hissing sound is driving me nuts... Is there any way I can return this laptop ? I have also bought a new SSD drive and have replaced it .. but now I can stand the hissssss sound when I start/stop a music,.. Please someone let me know how to return my laptop.. Bought from Lenovo Japan..

 

I think is it something to do with shielding of the speaker cables or something... anyways .. I am really going mad and want to return this...

A Lenovo investigation into customer reports of excessive speaker noise when playing through internal speakers on W550s and T550 laptops has concluded. A solution has been put in place.

 

If you are experiencing this issue, please contact Lenovo Service for Support and reference Service TIP SF15-T0065/ HT104239.

 

Thank you,

Hi Amy,

I am going to send my machine to Lenovo Tech today.. I have fixed this after discussing with the Tech support personnel at Lenovo Japan. He said he specifically didn't know what the resolution is but they will repair my machine... do you know what they will do?

Anyways.. I will update this thread with the result after I receive my machine back..

I opened a ticket to this problem as well (I have a T550 bought in May 2015) and referenced this thread in my ticket and gave them the case number from "Amy_Lenovo": TIP SF15-T0065/ HT104239

 

A tech support guy called me today. He said that he does not care what is written in this forum. Even if it is from Lenovo employees. He said he/Lenovo does not know about this problem.

 

He said that Windows 10 is not supported as Windows 8 was pre-installed once I bought it. If I would send it in they would re-install Windows 8. Which is a no-go for me that they wipe my whole system.

 

I am totally frustrated. Needless to say that this was my last Thinkpad.
