    Hi, I have an Early '05 Mac Mini (Intel) and the thing just now refuses to power-up. I have opened it and everything seems to be connected correctly. Any insight would be greatly appreciated. Kinda stuck on what to do here.

    Could be a dead motherboard. ALso, the intel mac minis didn't come out until january/february 06 - sorry, I'm in an anal mood.

    Sorry, my mistake.
    Tried reconnecting power to motherboard and nothing is loose. Its weird, it just doesn't come on anymore. Anyway to test the motherboard theory?

    Maybe this is just too obvious, but is the power supply still working?

    I do not know. I am not sure how I can go about testing this either.

    From the Mac mini (Early 2006) Service Source manual:

    No Power
    The Mac mini won’t turn on, no startup chime, no drive or fan sound, maybe no
    power on LED
    1. Make sure that the power cord is plugged into a working wall outlet, and that it’s properly connected to the power adapter. (To check if the wall socket is working, plug in a lamp or other electrical device.)
    2. Make sure that the power adapter is properly connected to the power port on the back of the computer.
    3. Disconnect all accessories that are plugged into the computer, such as a printer, hub, or iPod.
    4. Reset the SMC. (Refer to Reset the SMC mentioned in this chapter.)
    5. Try plugging a different power cord into the computer (if you have a working one available). If the computer starts up, replace the old power cord.
    6. Try connecting a different power adapter to the computer (if you have a working one available). If the computer starts up, replace the old power adapter.
    7. Replace the logic board.

    How to Reset the SMC
    The SMC (System Management Controller) is a microcontroller chip on the logic board that
    controls all power functions for your computer. If your computer is experiencing any power issue,
    resetting the SMC may resolve it. The SMC controls several functions, including:
    • Telling the computer when to turn on, turn off, sleep, wake, idle, and so on.
    • Handling system resets from various commands.
    • Controlling the fans.
    Note that resetting the SMC does not reset the PRAM. Resetting the SMC will not resolve issues
    in which your computer is unresponsive—in these situations, restarting your computer will
    generally suffice. If your computer isn’t responding, perform these steps one at a time, in this
    order, until the issue has been resolved:
    1. Force Quit (Option-Command-Escape).
    2. Restart (Control-Command-Power).
    3. Force Shut Down (press the power button for 10 seconds).
    Resetting the SMC can resolve some computer issues such as not starting up, not displaying
    video, sleep issues, fan noise issues, and so on. If your computer still exhibits these types of issues
    even after you’ve restarted the computer, try resetting the SMC. To reset the SMC :
    1. Turn off the computer by choosing Shut Down from the Apple menu, or by holding the power button until the computer turns off.
    2. Unplug all cables from the computer, including the power cord.
    3. Wait 10 seconds.
    4. Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
    5. Let go of the power button.
    6. Press the power button once more to start up your computer.

    This is the problem. I dont have the accessories needed to test the power box. And I do not have a logic board. -_-

    Did you try resetting the SMC? If so, and that was unsucessfull, then I think an Authorized Apple Service Provider is your next step.

    Thank you for the advice though!

    Okay, I just had one more idea come to mind, maybe it's the battery? Here's why, I have an iMac G3, and when it was around 4-5 years old it had the PRAM battery die and the symptom was that it would do nothing. Just like it wasn't getting any power. I replaced the PRAM battery, ($12 from Radio Shack) and reset the PMU (the SMC on newer Macs) and I was back in operation. I know that the usual symptom of a dead battery is that it doesn't remember the date and time (my current iMac G4 has that symptom but still boots) but with the iMac G3 it was effectively dead from the dead battery. Maybe the same is true of your mini. It's the only thing I can think of besides a trip to an Apple Authorized Service Provider at this point.

    Hmm, good idea. Is it the little silver battery standing upright inside of the Mini?

    No :( the PRAM didn't work. Got the new battery at Radioshack for $5. I don't know what the hell to do now.

    This is the only other thing I can think of other than taking it to an Apple Authorized Service Provider:

    Apple Power Adapter 110W for Mac mini $49.00

    Hi,

    The new Minis are very nice right now. If you can handle $50 a month for the next 12 months you would have paid one off.

    I know. Not the answer you need right now. The problem is that computers are not worth fixing anymore. A logic board replacement would probably cost near the price of a new mini (I'm guessing).

    I had similar issue happen to me at work couple weeks back. The mini won't power up, our tech guy found out that the mother board was damaged and ordered a replacement and fixed it. Now I am writing this comment on the fixed mini.

    My suggestion is to take it into your nearest apple authorized repair shop.

    Mac Mini

    I've looked it over just about every way I can. This thing is dead. I don't really have the money (or warranty) to take it to Apple. :,(

    To eBay as a parts machine then. Even if you had AppleCare it would be over by now.
