That's quite strange.
What Mac with what OS are you using? Are we talking about the latest Studio Display ? https://support.apple.com/en-us/docs/displays
Have you just bought it recently ? Used second hand or not ?

What Mac with what OS are you using? Are we talking about the latest Studio Display ? https://support.apple.com/en-us/docs/displays
Have you just bought it recently ? Used second hand or not ?
Most recent sequoia then installed most recent 26. Always had this monitor. Never knew about brightness setting. The issue occurred because I wanted to add applecare one but it wasn't showing up like my other studio display.
Again, what Mac is connected while you having that trouble?
Also if you have an other ASD, what do you see if you connect the other ASD to your Mac? Same problem ?
What is the firmware version of the display?
Maybe this video (even if older) will give you some more info about what problem you are dealing with. It doesn’t tell you exactly how to get your settings back, but there are some hints where to look and check.
Hi guys,
new ASD owner here (got a refurbished one with a huge discount—almost new).
To the experienced ASD users: how to you manage powering your ASD connected to a Mac?
My setup: MBP M5 hooked up to the ASD via a single Thunderbolt cable provided in the box.
I m using my MBP (almost exclusively) in clamshell mode. When I set my MBP to sleep, the ASD will go also to sleep, which seems to be correct. However, the 2 fans of the ASD keep on running while in sleep mode. I do think this is not good in the long-term, fans constantly running 24/7 (wear).
I think when I shut down my MBP instead of sending it to sleep, the display will power off—and the fans will stop (?). But will my MBP still be powered via the attached Thunderbolt cable? Or will the battery of my MBP now be drained because there is no power source any more (because the ASD is off)?
What is your recommendation/experience?
Thanks a lot!
Kind regards!

I'm not sure if you have much of control here, since ASD has its own brain (technically there is an iPhone inside)
the moment you plug it to the wall that thing is on.
Yes, I know..it is more or less an iPhone 11 with the A13 Bionic 
However, anyone tried the following or experienced the following:
- Shut down Macbook/Mac mini/studio --> ASD goes off
- Let the ASD power cord plugged in
- Let the Thunderbolt cable plugged in the Macbook so that it is still connected to the ASD.
Questions:
- Will the fans of the ASD still keep on spinning despite the Macbook is shut down?
- Will the MacBook still be powered via the Thunderbolt cable despite the ASD is off or will it now drain the battery?
Or is the only possibility to stop the ASD fans by either:
- Detach the ASD power cord from the power socket
- Detach the Thunderbolt cable from the Macbook (but then the Macbook won´t be powered anymore therefore draining battery)
Just to make sure, I want to set up the best configuration while in clamshell mode.
Kind regards!

@C0re0 "Will the MacBook still be powered via the Thunderbolt cable despite the ASD is off..."
If the sleeping MacBook Pro is still charging whilst connected to the ASD, then the ASD's internal PSU will be providing that power, and the fans will be needed to cool it, so will be 'on'.
So that would be an expected behaviour...

Best configuration.. for your MBP battery longevity? I would imagine clamshell mode is not it. But I digress…
ASD will provide power to your connected MBP, and USB devices attached to the display, when MBP is shut down.
A week passed and no repair yet. Has anyone received a completely new/refurbished one in a white box? (in cases where they cannot just change out the front display)
Hi,
I bought a refurbished ASD from the Apple refurb Store and it came in a white box. I think all Apple refurbished products will be shipped in a white box.
Hi have observed the following:
Yesterday morning - before a short leave from home - I set my MacBook to sleep and consequently the ASD went off (ok, normal behavior because the ASD did not get any input signal). I noticed that the fans of the ASD kept on turning for about 10 seconds and then went off.
However, when I was back I realized that the fans of the ASD were running while the Macbook was still asleep. Therefore, the display itself was obviously not in a sleep state.
Yesterday evening, I shut down my MacBook - and the fans of the ASD went off (ok, that´s normal).
This morning, the fans of the ASD were still off and turned on once I booted my macbook.
To summarize, there is no real "sleep state" of the ASD - the fans will be running from time to time. Probably when the MacBook does some background activity but I do not know. But it's really some kind of frustrating that there is currently no real power-saving mode of the ASD in which the fans don't run in the long-term. Regarding power consumption, this is an issue.
I also did some research on the internet. Apparently, there are numerous threads describing the same problem, and it seems to be caused by MacOS, especially with the introduction of version 15.4.

Still not solution available. Therefore you either have to shut down your Mac, or unplug the Thunderbolt cable, or unplug the power cord of the ASD to really turn off your ASD.

First, my setup is a Mac mini M4 connected to a ASD. The biggest problem is the difference between setups ASD with a Mac mini and setups ASD with a Macbook. Some users just connect the Macbook with the TB cable to the ASD so it is getting charged via TB from the ASD power supply. In this case it seems to be just logical that the ASD needs to cool his power supply and the ASD fans run all the time.
After reading how to setup clamshell mode (I don’t have or use a Macbook) it seems there is no need for the ASD to deliver power to the Macbook because it's connected to his own power supply. So if this is correct, the conclusion could be, a Macbook in clamshell mode connected to a ASD should behave like a Mac mini connected to a ASD.
Lots of if, could and would. You can read details about behavior of the ASD (with Mac mini) in this thread. https://forums.macrumors.com/thread...s-are-in-sleep-mode-since-macos-15-4.2457769/
There are still some important differences between Mac minis and MacBooks because MacBooks have additional and/or other settings in energy settings, what makes it impossible to compare a device behavior even with the same settings because there is always the chance that one setting the other devise doesn’t have makes that tiny little difference why or if the ASD fans keep running.
In fact I’m watching the ASD fans since December 2024 and it is 100% confirmed from other users, the ASD fans changed behavior right with / after the macOS 15.4 update.
Can you provide us a screenshot of your energy settings and what macOS you use (not sure what OS Apple did put on that brand new device or if you use any beta) Also pleas check the ASD firmware version.
I wasn’t able to find any Mac mini user with macOS 15.4 and later where the ASD fans stop after the background tasks of the Mac mini. Did not take any attention to Macbook users because of the mentioned differences.
We need to get rid of this unnecessary wear and tear. If the ASD Display is black and no power gets delivered to an other device, there is absolutely no reason for the ASD fans running.
It is interesting you found your ASD without fans running this morning. Need to know more about that. Thanks.
Hi,
Thank you for your post which is also very interesting!
I will post battery settings later - currently I m not at home. I agree that there should be a power saveing mode on the ASD.
As an „experiment“: Connect the Macbook to the power socket with the USB-C cable and Apple 70W/96W power adapter while also being connected to the ASD via the Thunderbolt cable. Would the Thunderbolt cable in this situation only deliver the picture to the ASD without power/charging the Macbook?
When finished with work, I would shut down the Macbook and detach the thunderbolt cable. The ASD will shut off, but the Macbook will then be charged via the USB-C power adapter.
Would that be an option?
Kind regards!
Yes, I noticed this too. ASD seems to be always on and maybe it is because Apple wants the monitor to turn on immediately when coming out of sleep mode. We might just have to accept this as I don’t see Apple changing this. If they did, then there would be a longer delay for the monitor to turn on.Hi have observed the following:

As long as you’re aware and OK with nothing that is plugged into the ASD being powered when you do this, the solution I’ve been using for the last 3.5 years and change is to just plug the ASD into a smart powerstrip I picked up off Amazon. The one I got was just for Alexa (but I use Home Assistant so it works fine with HomeKit in the Home app) but there are decent HomeKit ones available now like this https://www.amazon.com/Tapo-Extender-Protector-Individual-P306/dp/B0CYGSFFFW/ — I have mine assigned and basically can say “Alexa turn on Studio Display” or “Alexa turn off Studio Display” — but you could do it with Siri too.
Then I just have it attached to a smart outlet and choose to manually power cycle it or turn it off when I’m going out of town. The one caveat is that it takes at least 5 seconds to turn on, when you power it from being off. Which isn’t the end of the world, but is a bit longer than other monitors that have an actual power button.
If you don’t need a full strip, you can get individual smart outlets too.
I think not having a power button on a display that has an old iPhone inside it and sometimes gets software updates is a bad design choice, even if the default option would be to leave it powered on at all times. I feel the same way about AirPods Max. I like the ease of use of always-on, but headphones should have a proper power button, even if the default way of use would be to have them go into deep sleep or whatever.

Hi,
Thanks for this! I also read in another forum that a homekit associated smart plug would be convenient to switch off the ASD. However, the only drawback would be then that a connected Macbook won´t be charged anymore via the Thunderbolt cable because the internal ASD power supply is supposed to be switched off, too...
Do you have a Mac mini/Studio connected to your ASD or also a Macbook?
I agree that it is a design fail to omit a power switch on the ASD.
Kind regards!

Love my ASD but the lack of a power button is a huge oversight IMO.
I have mine connected to a Mac Studio - always put the system to sleep when not in use and the ASD fans always stay on. Guess I've just got used to living with it now.
If I used a smart plug would the switching on/off cause any damage to the ASD over time considering its not designed to be powered off in this way?

That's a very good question, because I have exactly this configuration here and have connected my ASD to a smart power outlet and switch it on when needed.
But whether the ASD was designed to be switched on and off 1-2 times a day is the question. IMHO, it should definitely be able to do this as a monitor.
So, I have an iMac and two MacBook Pros. There is a world where I could get a switcher of sorts for them, I’ve seen others posted stuff, but I usually just use my Thunderbolt dock (a CalDigit TS4+, tho I have a TS3+ too) and swap that way (the iMac gets a lot less use these days but the work and personal MacBook Pros are usually not permanently connected) and then relegate the USB ports on the ASD to a Lightning cable for the Magic Keyboard/Magic Trackpad and the Elgato webcam I use with the MacBooks. External drives and my microphone and mixer stay connected to the dock.
With that setup, I don’t have to worry about my MacBook losing power if I turn off the ASD, but to be honest, I usually only turn it off when I’m out of town (which averages a week or two a month) or when I need to power cycle.
I think it would depend on how often you turned it off, I guess. If you were doing multiple reboots a day, maybe that would impact longevity (but it would also get really annoying to have to wait everytime you want to use it), but if just do it when you’re done for the day or when you’re not planning on using the machine, I don’t know if I would be concerned. For me, this is one of those areas Apple Care is for, especially if Apple couldn’t be bothered to give a proper power button, but I don’t have a sense of how many times the ASD has been rated for power on/off cycles. But I’ve done it at least once a week for close to 4 years and would personally feel comfortable doing it more than that. I just don’t think I would do it multiple times a day.
Fully agree that any monitor of its price should be able to support being switched on and off multiple times a day. I just don’t know if the extra guts inside effects that at all. But I guess an iPhone is also definitely designed to support being powered on and off multiple times a day, so it’s honestly probably fine.
As I said up thread, the bigger annoyance for me would be waiting the 5-10 seconds for it to power on if I’m using it multiple times a day, rather than waking it up.
I'm very happy we finally get some opinions and statements about the ASD fans running unnecessarily and how users have found a workaround.
First of all, with a minimal setup the ASD fans did NOT run during display in standby (sleep) mode until the macOS update 15.4 This is a fact, but of course this depends on all kind of settings and maybe connected devices. Yes, it would have been nice to have a button to shut down the ASD if it's not going to be used for some (individual) longer time. But we need to remember there is also a hub included in the Display and for sure if there are devices connected to the hub that need power, the ASD power supply will get warm and the engineers wanted to cool it down. So yes, there are setups that need the fans running all the time because the user is taking advantage of the hub. Conclusion - no need for a button to shut it down.
So the main Problem is the minimal setup (nothing connected to the included hub), if the display would behave like it was designed we don’t need a button to shut it down because the fans wouldn’t run while the display is in standby (sleep) mode. The screen is black and the power draw is (should be) under 0,4 Watt. This is part of the statement Apple published with the Studio Display - Tech Specs https://support.apple.com/en-us/111890 inked here https://www.apple.com/environment/#reports-product linked to here https://www.apple.com/environment/pdf/products/displays/Apple_Studio_Display_PER_March2022.pdf
Also disclosed here https://www.energystar.gov/productfinder/product/certified-displays/details/2393684
Only reason for bringing up all this links is to proof, there in fact must be a sleep mode for the display, at least with a minimal setup. But, lots of users confirm, this is NOT working after the update to macOS 15.4 The ASD fans just don’t get or understand the signal to stop after the Mac mini is done with his background task. It is a simple bug.
So, statement of Apple second level support is, open a ticket. They need tickets, only using the feedback channel is not enough to bring it to the engineers attention.
Regarding the different kinds of workaround, some users use a smart plug to take the display off the grid. To do this is everyones own decision and until now I haven’t heard about any trouble with the ASD doing this.
Throwing in my opinion and thoughts about just unplugging that kind of device more or less frequently:
We all know for some reasons Apple did put in an iPhone chip and (IOS ?) OS. I don’t think it’s a good idea to just take off the power without shutting down the system of a device that runs an OS. Sure it depends on how often you do it, but would you do this to your TV, printer or Mac? At least for the Mac all readers here would answer NO. IMO the ASD is like an iPhone, if you shut down ( ! ) your iPhone and watch the screen you can see that little circle and the screen not being black black, that’s the two or three seconds thy OS is shutting down before the device is OFF. Taking the ASD from the grid is like pulling out the battery of the iPhone while it is in sleep mode (Yes I know we can’t do that)

Interestingly, in the EU (240V) the power draw figures are different:
21.2W for SDR power draw, and 0.5W for standby.
