XPS 15 (9560) Coil Whine

Please give Technical Support a chance to correct the issue but if problem isn't resolve, I strongly suggest you quickly return the computer and demand a new one.

EDIT:

Thanks!

There is no new bios for the 9560.

Also if I unplug the laptop, the buzzing is gone. Should I ask dell for a new power supply?

Two different computers. It might still work or it might not work at all. You can contact Technical Support in the link below:

And.....

Same thing here, everything is top notch. The only "issue" is this very light coil whine. Is very subtle idle and it can be heard only positioning the ear near the keyboard. However when scrolling in Chrome or in Word or in every scroll-able software it can be heard from a normal distance if the room is quiet.

When the notebook run on battery alone or when the powerline charge the battery itself the issue is much lighter (0 coil whine on battery).

The coil noise is from the laptop itself but also from the AC power brick, and also the scrolling enhance the issue n the power brick too.

The fact is that it's very light, and not always present. For example this morning at the first start up I didn't heard it. Now in very subtle but present.

Someone knew if there is a way to try a new power brick without send the whole unit back? Because I'd like to hear with another AC if the problem is limited only to that, without risk to replace the entire unit because everything is flawless and this is a very light issue.

P.S. Sorry for the bad english

To add my experience.  Yesterday received new laptop.  XPS 15 4K with the elusive fingerprint reader.  When I plugged the adapter in, a fairly noisy screeching/whine/buzz in a pattern sounding a little like a HDD accessing.  Contacted Dell support, they sent out a new brick, same problem.  Both bricks buzz slightly too.  Happens all the time when charging, at full charge when the laptop is on.  In standby and off with the charger charging/plugged in the noise stops.  Scrolling etc. doesn't seem to make a difference.  The noise is now much quieter and can only be heard when your ear is about 20cm away.  My friend has the older model XPS 15 with the Nvidea 960m.  His does it too.

As much as I like this machine and want to keep it, I just can't bring myself to.  It cost £1799 (approx. $2245).  It should be perfect.

I had a noise yesterday when I was doing a clean install on my system.  I think the sound drivers had just loaded but I was also installing the SD card reader drivers.  The sound seems to have come from the area of the SD reader but I could not pin it down.

I agree it seems to be related to traffic to or from a drive.  It did stop after I got all my drivers loaded and I have not heard it since.  You might try placing or removing an SD card, just in case it is related.

I intended purchasing the XPS 15 4K 9560 which has received excellent reviews. The coil whine noise could you keep me posted with further posts please. Also overall is the 9560 a quiet or noisy machine not taking into account the coil whine. Thank you.

I received my replacement laptop and I am 99% sure the coil whine is gone when I use the new power supply. Coil whine also appears on the replacement with the old power supply.

Old power supply was model HA130PM130 (coil whine) and the new model DA130PM130 (no coil whine).

I have the same issue, power supply model  HA130PM130, whines.

Dell support has not responded to my email request for a replacement.  Is there a different channel for requesting replacement of known defective device?

[ Update  3/13 ]

Dell support replaced my psu HA130PM130 with DA130PM130.  

- Coil whine on the psu DA130PM130 is less than the HA130PM130 ( not silent, but not as loud)

- Coil whine/buzz on the laptop (center, under function keys) remains.

Florian S von Dell is asking for more information about the mainboard with coil whining parts.

It would be great everybody could send him a private message with the content of the PPID.txt in the c:\dell folder.

Please use the following command line to create the information:

wmic baseboard get Product, SerialNumber, Version>c:\dell\PPID.txt

This is the thread in the german support forum:

Thanks @ all.

the two problems with my 9560 are the shift key is sticky/crunchy andI also have the coil whine. it is there when the power supply is not plugged in.

Has anyone found a fix yet? Has Dell said anything?

I got my new xps with same issue. Small but audible and irritating sound from laptop and AC supply when AC supply is connected. I have the same HA130PM130 power supply.

I updated my BIOS but the issue remains. will contact dell for new power supply.
