Mac Mini :: Display Won't Come Back From Sleep?
Aug 20, 2010
About a year ago, I convinced my mom to replace her old Flat Screen iMac G4 for a Mac Mini. We decided to buy a 23" HANNSpree LCD display, connected via Mini DisplayPort to VGA. Since then, my mom has often experienced the same issue: It is often unresponsive to waking from sleep, and sometimes it takes *ages* to come back to life, especially after the computer has fallen asleep for a long time (overnight).Sometimes, though I know the mini is awake, the display says that it cannot detect a signal coming from the mini.

Whenever we upgrade the Mini to an iMac, I have this vision of getting a vertical mount to hang our 20" Cinema Display under the counter in the "bill paying/desk area" of our kitchen. The issue I have is that I'm looking for something that will hang over the back of the display that you can hold the Mini in that does not take up the screws needed for the mount.
I'm thining of bending some Lexan to fit it in (see picture) unless anyone knows of something similar already out there to purchase.
Then I can just get a wireless keyboard/mouse and it will be a clutter-free area.

After discovering this new adapter and reading great feedback here on the forums, I picked this adapter from However, I am totally surprised that I have not seen one user feedback on how this adapter does not let your Mac go to sleep. I have tried this adapter on two macs at home, a Macbook Pro and an iMac, all latest models, running 10.6.2. Whenever I try putting it to sleep, the Mac wakes up after about 3 seconds.

I have a 2009 unibody macbook pro. I have 42 in lcd tv. I have a minidisplay to vga adapter and a vga cable. When I try to connect the monitor to the mbp when the lid is open nothing is detected. I do not get any options to change to mirror mode or am able to change any settings regarding the monitor. I can change the resolution of the built in display only. Now for the twist. If I connect everything, do a restart and close the lid, as the computer boots up the external monitor works. Its the grey boot screen with the apple logo. But as soon as the computer begins to load the desktop, the monitor losses the signal. At first I thought it was going into sleep mode, so I hooked up a usb mouse to keep the computer awake. I tried the process again, and as soon as it goes to the desktop it losses the signal. So I don't think it is sleep mode. I downloaded the minidisplay prot firmware update, but because the screen is not detected when the lid is open I cant run it. When the lid is closed the computer either goes to sleep or doesn't send the desktop signal and I still cant run it. Nothing happens if I change between the video cards (9400 and 9600gm). Is it a resolution issue? Do the vga cables have a max resolution that is lower than 1900 x 1200?

I leave my Air on pretty much all the time, and put it to sleep while moving around etc. Sleeping it disconnect the Airport connection - which if very annoying. At a desk I've just been dimming the display all the way off in order to keep my connection.
However, I recently noticed that by setting a "sleep display" hot corner, my network connection is maintained.
I have 2 questions:
1) Is sleep display equivalent (functionally) to simply dimming the display all the way down?
2) Is there a way to either set up a shortcut to sleep the display (other than a hot corner) and/or set it so that only the DISPLAY sleeps after 'x' minutes?

I have a macbook pro 13" early 2011 and I'm se as shown in the pictures (since i upgraded to os x yosemite) . It happens after display sleep or computer sleep on login not on boot up .I've noticed that i run out of ram when the problem appears (only 15MB RAM available out of 4GB), though i doesn't happen every time . I've talked to service and told me its either motherboard replacement or because the ram isn't enough (gpu shares with main ram) so maybe i should try upgrading ram. URL....

So I have a late 2009 Mac Mini hooked up to my Kuro via the mini-DVI to DVI adapter then DVI/HDMI cable to my receiver. I get digital audio out of the Mini via another cable. First question, if I were to use a mini-display port to HDMI adapter would I get both sound & video?
I love using PLEX but my Mac Mini is my only "computer" (I have an iPad). I would like to sit at my desk and use photoshop and other tools. Second question, can I do dual display using the mini-DVI and mini-Display Port jacks at the same time on a Late 2009 Mac Mini?
My gadget loving self has purchased a HP Wireless TV Connect. I was planning to use the dual HDMI output of receiver but I couldn't work on the PC and have someone watch PLEX so that is why I ask about dual screen (essentially extended desktop) using those two ports. The plan is to use a mini-display port to HDMI adapter and connect it to the transmitter of the HP Wireless TV connect and then an Apple display to the receiver. Make the main display the Apple display and the extending desktop running PLEX on that screen the Kuro.

I have torrents going all the time. If the computer goes to sleep, the internet disconnects, so they stop. Display sleep wouldn't disconnect though. Is it OK to have computer sleep on "never" but keep display on "15 minutes"? I don't usually even leave the computer on overnight.

I am running Mac Mini as a home server (turns out to be not a great idea, btw), and even though I set the preference to never sleep or shut down, it does go to sleep when there is no activity for long time. Since I am using it as home server, it should stay awake all the time or at least wake up from sleep when there is incoming ping from other computer, but it just goes to sleep.

My brand new 15 inch MacBook Pro was working fine for a week. Today the display went to sleep and when I tried to wake it, it remained dark, items barely visible. I could see the display brightness meter changing, but the brightness did not. Restarting didn't help. Called Apple and they're going to replace the computer. Has this happened to anybody else? Note: I have the hi-res anti-glare display.

I'm used to using the keystrokes control-shift-eject to put the display to sleep without activating the screensaver or putting the whole computer to sleep.
Since the new Macbook Pro with Retina Display lacks an eject key, the best I have been able to do is set a hot corner. I don't like this as much -- especially since it is possible to trigger the hot corner without intending to.

As of last night, my MBP started acting very strangely. After entering my username and password, it would enter the desktop for a short period of time and then kick back into sleep mode; the screen would turn back to black. Sometimes it will let me stay on the desktop for a long time and other times it will hardly let me stay on the desktop. I called apple support and they had me start the computer in safe mode; even then it occasionally kicks me out.
The tech guy said that it was a "strange software issue" and not a hardware issue. I thought it was a hard drive issue; my hard drive makes an odd sound when it unlocks (a grinding sound), but it has been doing that for quite some time with no issues. I tried to reset the SMC and it didn't do anything.
How should I remedy this problem? Is this a hard drive issue? Hard drive failure? Has the grinding sound finally caught up with me? I am running OS X; not leopard or snow leopard. I know I need to upgrade, but this shouldn't be happening.

I need to connect my 09' Mac Mini to my Yamaha RX-V2700 receiver which outputs to my Sony XBR HDTV. I know the mini has both mini-dvi to dvi and mini-dp to dvi or hdmi available via adapters. I was thinking to go with option 1 however I was wondering what is your opinions? Is mini-display port better over mini-dvi or are they the same? Audio will be carried over optical toslink.
Option 1:
Using mini-dvi adapter to dvi: Connect Dvi-Hdmi cable to receiver and output audio with toslink adapter.
Option 2:
Using mini-dp adapter to dvi or hdmi: Connect Dvi-Hdmi cable to receiver and output audio with toslink adapter.

Is it possible to switch off the mains when the Mac Mini is in sleep mode?
I've only had MBPs in the recent years and appreciate their low impact on my electricity bill very much - letting them sleep unplugged does make a difference. Now I'm contemplating a Mac Mini and while I know its power consumption is as low as with the notebooks (if not lower without display), I'm wondering if the Mini needs the current in sleep mode. I assume it does, but I'd rather know than guess.
Thanks!

I have a late 2008 15" MBP, and I often leave it playing videos while I go to sleep. Lately, it's stopped sleeping the display and/or going to sleep (depending on whether something's downloading in the background) after the video is finished, which is quite annoying as the screensaver's glare normally wakes me up in the middle of the night (and it's probably not too good for the display either).
Before a few weeks ago, it would quite happily sleep the display a few minutes after the video (in Front Row or otherwise) finished playing, but it's now consistently ignoring the sleep and display sleep settings (which are all correct). I even set the display sleep timer to 1 minute, waited without anything happening in the background, but nothing happens.
Anyone have any idea how to get the timers to work again?

So this past week when my mini hasn't stayed in sleep mode, it shuts itself down about a minute later after being in sleep mode. I haven't changed any of my settings in a year and a half, normally it would stay in sleep mode until i come back to it and logged on again. When it does shut down i just cannot power back on i have to unplug the adapter then replug it in for it to start up again. I've searched google and on here for possible ideas. I wouldn't think it to be overheating since I'm not running any applications when i put it in sleep. It might be the power supply since i have to do that process to get it to work again. Let me know what could be causing this or ways to troubleshoot this problem.

I'm getting a high resolution, and it looks alright, but it's not fully using the widescreen. That's "aspect" right? Well anyway, I also have a 19" display and it works perfectly. My Xbox, cable box and movies all use the full widescreen on the Acer, but the Macbook with the super amazing Mini DisplayPort doesn't even use the full resolution. What's with that? I thought the reason they had this new port and a $30 adapter was for higher resolutions!

I hooked up my macbook pro to a mini display port to a dvi -> hdmi to my tv no problem. However, when I hooked up the mini display -> dell monitor, I get nothing. The screen is black. The weird thing is that my macbook pro recognizes that a second monitor is plugged in... it just won't display anything

I want to buy the 27" iMac - but only if I can use it as external monitor for my Lenovo laptop when working from home. A the Apple store in London they said that this is possible with a Belkin converter from hdmi to mini display port (with a USB power caple to turn it into an active signal). The laptop also has a displayport.

iMac

I have a mid-late 2008 MacBook connected to a Dell U2211H monitor using a Mini DisplayPort -> VGA connection.
When I use 1920x1080, I only get 60 Hz and the display is a fuzzy (text). Also, there are black bars. Why?
Will my issues be solved using a Mini DisplayPort -> DVI connection? Or should I exchange it for the 2209?

I have just purchased a new Mac Mini (MC816B/A), it is to replace an old PC. The PC is running two monitors through a dual display graphics card, and in the short term I'd like to use these until I can afford Apple displays.
The back of the Mini has an HDMI port, Firewire and a Thunderbolt port. How can I use my two regular displays (they are TFT and have VGA and DVI connections)? There are also 4 x USB ports as well.

i have a 15 inch apple studio display which has ADC (was partnered with the cube) and I purchased a DVI adaptor so it now works fine with the DVI port on the macbook pro. I am considering a new mac notebook (not sure which yet) but as these have the new mini display port, is there an adaptor that would slot into the DVI end of my current one, so it would work with the new macbook?
