Loose DC power plug on Mac Mini.

The DC power cord on my Mac Mini has a very insecure connection where it connects to the computer. It is easy to pull out if the power cord is bumpped or tugged even a little. I don't think mine's broken I just think it's made this way on all Minis.
What's the best way to fix this? Duct tape, silicone seal, super glue, zip tie
The people who designed the rj45 (ethernet) connector did a great job, it's low cost reliable and locks in place. Why couldn't Apple do as well?
Am I the first the notice this problem or maybe the connector realy is broken?

Mine is OK too. Not tight, but certainly not loose.
There are regulations in a number of locations requiring that electrical supplies can be readily disconnected in an emergency, so a power connector that captures the cable in the same way as the ethernet port does wouldn't really be practical. But from reports here in the past it appears the connector on some minis is more loose than on others. If yours is sufficiently loose when fully connected that it can be jiggled out, and if your mini is a new one, I'd call Apple to report the issue. They may have no better suggestion that to wrap the connector with a single turn of electrical tape, but at least they can log the call to build a picture of how many complaints on the issue are being received.

  • Power on Plug Support - Mac Mini

    Hello all.
    I was wondering if anyone knows how to implement a power on plug feature with the intel based Mac minis. More specifically, I am trying to get the Mac to automatically turn on after a power outage when power is restored. Many LCD TVs and monitors have such a function.
    Is there a way to do this with the Mac?

    Thank for the help and nice find!
    If anyone is trying to get this functionality using solely Windows, you will need a program call WPCRSET to set the appropriate register on the Intel 82801GB ICH7 controller hub. Mac OS automaticaly sets the register during boot, but Windows does not. WPCRSET install a system service that sets registers during Windows startup. I have tested it and it works on Vista.

  • Unable to Troubleshoot Power Issues on Mac mini 2011

    I have been having odd and intermittent power issues with my Mac mini 2011 and could really use some help before I resign myself to taking it into an Apple Store. It's under warranty, but I now live in another country so I hope I don't need to ship it should it come down to that.
    However, I have searched this topic a lot, and not only have I tried troubleshooting it, I haven't seen any power issues with other owners of this model. That leads me to think that the power supply itself is probably OK.
    First of all, I live in China and the building I live in seems to have a questionable power supply. The air conditioner for example simply would not work and the repairman spent two hours messing around with wires inside the outlet and in the breakers. That did the trick, so I wonder if I'm simply not getting enough juice?
    Main symptoms:
    - My monitor recognizes an analog signal but will not light up (black monitor). Unplugging and replugging adaptor doesn't do anything.
    - Startup Keyboard Commands (e.g. Cmmd-R) may work, but I can't tell because the monitor won't light up. Letting the computer boot up though I can hear keyboard volume keys and such making the standard sounds. I can usually restart using the keyboard too.
    - My 2T external HD more often than not dismounts as well.
    - I can't hear any computer activity after the chime (hard drive, etc.).
    - Since I can hear the chime and there is audio feedback through the keyboard, I think that eliminates hardware problems such as logic board failure or bad RAM.
    - I can't boot even if I unplug all USB peripherals.
    - Holding down the power button (I have it set to make the computer sleep as well as shut down) often won't shut down the computer, but it seems to stay in sleep no matter how long I hold it. Unplugging the computer finally shuts it down, obviously.
    - Unplugging and waiting 5 minutes or so and powering up again doesn't seem to make any difference, nor does switching sockets, plugging directly into the wall, etc.
    Problems began about two weeks ago, got better, and then worse again. Now I'm just keeping the computer and monitor on (never sleep 24/7).
    Miraculously, after much frustration and countless restarts, suddenly the screen will turn on to reveal a fully booted system that was running all along in the background. No startup screen- the monitor just magically comes on again. Often I find that my external has unmounted, but it's no big deal to get to remount. At this stage, the Mac is still very quiet and for a while the system is sluggish, though it hops back into action in 5 or 10 minutes.
    At first I thought it was just my monitor, and though that's possible I suppose, it seems I'm just not getting enough juice. Once the monitor is on though, everything is fine: I can power it off and on with no problems. But I can't just leave my computer on forever though.
    Any help appreciated.

    Well, with the other monitor (which did not work with the mini either but worked fine on a laptop), I was able to narrow the trouble spot down to either a faulty Mini Display to VGA adaptor or a damaged port. I could determine that all the other ports (incld. the USB drive, programs, internet, etc., were all working fine behind the big black GUI all through sound feedback, so I seriously doubted it could be a supply problem or a residential electric problem.
    I took my mini and adaptor to a "Mac Shop" (reseller) here in China, and found it quite professional, just like a Mac Store. They tested my machine, and although they didn't have VGA monitors, they said I could return the new $30 USD adaptor if it didn't work. But as I'm writing this on the monitor now, the new adaptor did the trick.
    The long and short of all this is that I've read a lot about display problems with the mini and I suspect that most of these problems are adaptor related. I myself tried to save some bucks by buying a third party plug and lived and learned. I hope the Apple adaptor works like a champ, and if it doesn't, I'll know the first thing to eliiminate next time.

  • Pb screen fuzzy plugged with mac mini and hdmi cable

    Hi all, I bought my first mac yesterday and I plugged it it this morning on my tv screen with an hdmi cable. I saw that the screen at the bottom where all the icones are is fuzzy. We set it up at the apple store and it was working well. Could you please help me.
    Thanks a lot for your answer

    Well, here's to a happy conclusion.
    After bugging the local electronics store for two days in a row, I've found a working Full-HD TV.
    Lessons learned:
    a) Be thankful for stores where you can bring in your own computer and hook it up to the TVs on display.
    b) Don't just glance at the manual.
    After trying several TVs and not getting any good picture by either connecting by VGA (consistently showed slight ghosting with high-contrast colors) or HDMI (all TVs did cut off Dock and menu bar), neither the salespeople nor I had any idea what else to do.
    The next day, it hit me: We had tried all kinds of setup/config selections from the TV's setup menu.
    What we did NOT do was to simply try it with the "Zoom/Aspect" button on the remote - partially because that didn't work with the first model I bought.
    So, Mac mini back into the suitcase, back to the store, "Ah, you again...", hook up the first TV set, press "Zoom", pick "Truescan", press "OK" -
    Problem solved. Pixel-perfect alignment. => TV bought.
    Just for those looking for a "known to work" answer: It was the Toshiba, XV 500 series, older model. It's running on "1920x1080 @ 60 Hz (interlace)", but since I'm using it as a monitor, the "interlace-only" doesn't bother me too much. No problem even when watching DVDs via the mini.
    Image is stable, text is crisp and readable at 5-6 ft. distance, dimmed-down lamp is more than adequate even at minimum brightness since the room faces north. Low-power setting of the lamp makes for only 70 watts consumption instead of the rated 180+ watts.
    Happy user here now

  • 6 GB iPod Mini discharges when plugged into Mac Mini via USB 2.0 hub

    I have a 6 GB iPod Mini and when i connect it to my computer, instead of charging, it discharges. The iPod is connected to a self powered USB 2.0 hub. Does anybody have any ideas of what to do. I need a hub because the Mac Mini only has 2 USB ports and the keyboard and mouse don't work through the hub (well the keyboard it self does but the hub doesn't which the Mighty Mouse is plugged into)
    Thanks

    When i say self powered i mean that it has an external power supply (my hub it has two lights, when it is connected to USB and has p\s connected and plugged in a light lights up that has the word "Self" next to it, when it is connected just to USB it has a light that lights up with the word "Bus" next to it.) I am sorry if i confused you (or if i confused myself). About the firewire thing, i am planning to get the next normal iPod Apple releases but the current ones dont support firewire so the new one probably wont either, so i will be in the same boat as i am now when i get a new one.

  • Uninterruptible power supply for mac mini server

    can anyone recommend a good UPS for my mac mini server? i am a novice with these things so any advice appreciated: what i should look out for, will i need extra cables or can i just plug a uk plug directly into a ups, price v performance (there is a big range)
    thanks

    I would recommend you go with a small Smart-UPS, something like the APC Smart-UPS 750VA LCD. The 750 is a line interactive unit, offers avr boost/drop, surge protection and outputs a sine wave. This unit will provide you data center quality protection.
    The Mac Mini consumes about 110W of power, so with the SMT750 you'd have over 35 minutes of run time on the unit alone. If you have routers and switches, it would reduce the run time a bit, but you can protect more equipment.
    I wouldn't recommend going with the Back-UPS series of UPSs. They're not really designed for sensitive equipment and don't offer nearly as much protection as much the Smart-UPSs. We can't use them here at all because they don't get along with most Mac power supplies because they don't output a sine wave. Overall, they're just not as good as the Smart-UPSs.
    We use the North American version here, in Europe you'd be looking for a SMT750I, "I" being the international edition.
    We use a variety of these UPSs here at our office, they work like a charm.

  • Unexpected power off now mac mini want boot up pass the grey screen

    i have a mac mini the power went off when it came back on and i tryd to cut mini back on it only went to gray apple screen them goes out the monitor says not supported i need to get class assignments off of it.

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
         a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
    b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
    c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
    Step 9
    If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.   
    Step 10
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 11
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 12
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 13
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

  • Display Turns Black and Won't Wake Up Unless I Power Cycle the Mac mini

    Even when I disable all the power settings on my Mac mini, after a day or 2 at max my Mac mini's display will go black and stay that way. Whether I connect to it using VNC Screen Sharing, or connect a monitor directly to it, I can't get the screen back on unless I either power cycle the computer, or otherwise SSH into it via the terminal on my MacBook and force it to log off that way. Any suggestions? Does this sound like a hardware problem, setting, or software problem? I notice that it happens most frequently when the CPU is being worked intensively, like if I'm downloading a lot of files with Vuze or otherwise doing heavy video conversions with iSkysoft iMedia Converter. I heard that maybe the Mac mini is overheating, but it's not stacked and lately I've tried moving it to several different locations but still the problem persists. I also notice that usually when I SSH into it via the terminal while the problems occur that my CPU usage will be way lower than it should be, since it might have happened during the onset of a long/heavy video conversion process. I have a Core 2 Duo, 2.2 GHz Processor with 4 GB of RAM and about 140 GB of available storage. What do you all think I should do?

    couple of things you should try:
    boot up in _*safe mode*_, the restart normally
    try _*resetting the System Management Controller SMC*_
    try _*resetting your Mac's PRAM and NVRAM*_
    if none of the above makes any difference, run _*Apple Hardware Test*_ from the install DVD that came with your Mac to see if it reports hardware problems.

  • Power failure in mac mini?

    i was thinking of buying a new mac mini. But always concern what will happen if power failure and i dont have a ups hooked to it.
    Will it save and go into sleep mode or it will shut down? will i lose what i was doing if something like that were to happen?

    Hi kmfaizal,
    yes the mini does not have a battery unlike laptops. If your power supply is shaky you should either get a UPS or a MacBook.
    When the power fails, the mini will shut down immediately and not gracefully. You lose the work done since your last save. If the mini was saving files when power was lost, your saved file may even be unreadable.
    You may find a TimeCapsule invaluable to continuously back up your work. (But that would require a UPS anyway).

  • Checking the power consumption of mac mini

    i have a PPC mac mini. Is it possible to monitor/check the power consumption of the mini, as well as peripherals attached to it, say like an external firewire disk. System Profiler doesn't give such information.
    should this post have been under the category of "using OS X"? If so, could the moderators move it to the correct category
    Message was edited by: Ravindra Holalkere

    If you are looking for a software solution, there isn't much of one. A server grade UPS may have some monitoring ability that you could access, but otherwise, you would have to hook up some test equipment to get the actual power consumption. All is not lost, since pretty much all electrical equipment (especially if it is sold in the US) has a label that tells you what the maximum power consumption is. The label usually states the voltage and the current, which multiplied together roughly equals the number of watts - in the case of a PPC mini, about 85 watts.

  • Ethernet Cable Plugged Into Mac Mini, but it says it isn't.

    I'm all new to the MacWorld, just got my Mac Mini yesterday. . . .
    So I want to create a network between my PC + Mac by direct Ethernet for the Internet and file sharing.
    I've got everything done on the PC end, but when I try to get it working on my Mac it says that there is no Ethernet Cable plugged in :S
    Any suggestions on what to do?

    If I understand you, you have run a cable directly from your pc to your mac. If this is the case, you need to run a crossover cable, not a standard ethernet cable.

  • What is the upgrade path for osx ver 10.4.11 on a power pc g4 mac mini?

    We recently set our old Mac Mini back up.  It has a 1.24 ghz PowerPC G4 with 1 gb of ddr sdram.  How do we upgrade the os on this system?  We have applied all security updates available in the Apple Update.

    I believe that the best you can do is to upgrade to Leopard. You would have to look around to find an upgrade disk.
    Snow Leopard requires an intel processor.
