The page here: 

notes the following fixes & enhancements:

Fixes
- Modify Batman feature - battery charging threshold feature.
- Update the F9 hotkey function for some multilateral input method.

Enhancements
- Improved System BIOS stability.
- Support Realtek USB-to-LAN dongle(REL8153-VB) PXE boot.

No mention of coil whines but we can still hope.

RE: XPS 15 9530 - Noise problem?

I tried to update to BIOS A03, the Windows updater went well, then the computer won't restart.

Black screen for 25 minutes, then I manually turned it off and on, and the machine booted.

The System Info shows A03 but the coil whine is still there.

RE: XPS 15 9530 - Noise problem?

I had high hopes with this A03 version :(. Just got my replacement today. Soon as I give it a try will post the results. if the noise is still there I'll ask for a refund, had enough of this<ADMIN NOTE: Profanity removed as per TOU>.

RE: XPS 15 9530 - Noise problem?

I also tested A03. Upgrading worked without any problems. Coilwhyning is still there, did not change. BIOS setting to stop charging at a certain amount of charge works now, but does not solve the problem.

... so I still work with headphones on when the system is not charging and powered by the adapter.

Hope Dell can fix this with A04 or replacement of the component which makes this noise....

RE: XPS 15 9530 - Noise problem?

Thought i would copy this post from the other forums, again, from mentioning on page1 the source of the issue.

Now also on the A03 bios enjoying the long awaited battery management.
As others reported: Coil whine is the same.

Just wanted to respond to your "different coil whine noises":
It is the load and the interrupts the processor sees. Changes over the day, are because something is beginning to run in background. For example indexing or something else.
I use windows and linux here. The sound is different. Because the cpu govenors (load/frequency control is different). In general I feel win 7 more noisy (may be the cpu switches more often to one sleep state). When some very low -priority background task is running, e.g. a file indexer (locate db for example under linux), the noise changes.
I tried under windows (throttle stop) and also under linux (some kernel boot parameter) to restrict the CPU to fall into deeper sleep states as C3. No chance to affect the sound. Actually I have the feeling, that it both (windows + tool or linux kernel) should work, that the c-states are somehow hard-coded in the haswell cpus or the try of software to affect it is blocked by the bios. I can not really meassure differences in power consumption with (both win7 + linux) when trying to restrict the cstates >3 (haswell goes down till c7).

With all the clock settings (intel CPU tuner software) and different govenors and voltages and load conditions. I can say: The whine is definitely the CPU and not the internal graphic as some suggested.
I hoped the battery charging is the last resort. But it is not. The only left thing we could hope (and because dell sells to mainstram users, dell will never unlock the bios settings for having direct control to c-states) 
People accept it - if dell will not open the advanced bios/chipset settings as usual on good desktop boards

Have contacted dell support  via twitter "@DellCaresPRO: @Noodle8or Hi Rhys, we're aware of the noise issue on the 9530 & a solution is being worked on. Once there is an update I'll let you know^HC"

RE: XPS 15 9530 - Noise problem?

Just played with my 3rd replacement. Noise is still here. Is pretty safe to assume that all the XPS 9530 machines suffer from this noise issue. If yours is the same, Dont bother for replacement, it will be in vain. Will contact support tomorrow. Still thinking if to refund or not (I know right?!). The way Dell handles this issue it's an absolute joke. 

Terry B, 

If you still work for Dell, can you please give us some updates on this problem ?! Anything really will do, you know like at least we can see where the problem is and we are working on the best way to fix it?! It's pretty safe to ASSUME ITS COMMING FROM THE PROCESSOR.

RE: XPS 15 9530 - Noise problem?

Hi guys,

as everyone else here I have been following this noise issue for a while.

As people know the newest A03 bios is out. 

I tried it out yesterday - and to my surprise I think something has changed in positive direction.

To be frank - I stopped perceiving the noise issue since yesterday. Its like completely gone. I can only hear the electric noise buzzing when I shut down windows - > when it says shutting down or when i boot windows at the very beginning as it loads icons into the taskbar next to the clock. But even that is very light noise compared to before...

During the operation of Windows its not  perceivable any more. As many others here i have very sensitive hearing. Fingers crossed it stays that way... 

 

My original problem:

- I am one of the people who had noise when the power charging has reached 100 percent -> the noise would start 😞 If battery was at like 80 percent and charging it would not make much noise...

- on battery usually i didn't perceive noise. Sometimes I did though. 😞

- the noise would NOT change to less when I turn off the keyboard LED 😞 

 

My current configuration :

- Windows 8 running at 3200x1800 resolution (changed yesterday before updating to A03 - was running 1920x1080 for a while -> maybe that made difference?! and not the bios A03 update)

- A03 bios with setting in bios USING AC Adaptor primarily

 

Good luck to you. Hope you have similar experience. For now fingers crossed it stays silent.

RE: XPS 15 9530 - Noise problem?

Hi everyone,

I have dell xps 15 9530. My model never had severe noise, but for sure was there since the beginning. My unit had a screen replacement on the first week and logic board + heatsink on third week, due to severe throttling. After this replacement of the logic board the heat issue got much better, but not as good as i was expecting.

I seems that the tech from dell just applied to much thermal paste. (just saying)

Prior to this machine i had a dell precision m4600, and that was a really good machine. Never felt it getting hot or making noise. 

Well, back to the xps and noise.

After bios update to v. A03 the noise is gone. completely. 
I went to check the bios, and notice to things diferent from my prior setup. AC power adapter was selected, and usb awake support was disable. 

I don't know if there's any relation between this settings and coils noise, since i didn't test, still enjoying the silence 😄

RE: XPS 15 9530 - Noise problem?

Correction:

Noise is back. 😞

So I have been using the laptop for couple of hours since A03 bios update and found some interesting things.

When I close the lid and put it to sleep and then wake up -> the noise is back. 

I found when I restart the laptop into a fresh windows session the noise seems less but somehow it returned afterall. When I was writing my preivous post it seemed gone...

Right now it seems like the noise is back.<ADMIN NOTE: Profane word removed as per TOU>
