Early '09 mini won't power on

Sigh, this past week I tried to turn on my early '09 Mini and it wouldn't do anything. I tried resetting the PRAM, replacing the PRAM battery, and finally gave up. Took it to an Apple certified local shop (not sure if I can mention the name here) and they said it was a dead logic board and would be cheaper to replace the Mini. It bothers me if that is the case. My MacBook is still going strong and takes far more abuse than this thing ever saw. Is there any way I can personally verify it is the logic board? I really have no desire to buy a new Mac currently or buy a logic board that's almost as expensive as a new Mini...

I wouldn't get too hung up comparing the mini to your MacBook, as the portables have a different design point.
The easiest way to confirm a logic board issue is to take it to another shop. The mini is pretty straightforward ... if it won't startup, showing no signs of life, it almost has to be the logic board (assuming of course that the power brick is working). Since you have an Intel mini, did you do an SMU reset:
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
You may have effectively done that when you took it to the local shop.
When you bought the mini, did you use a credit card that offers warranty extension coverage as a benefit?
You could look to buy a used logic board, but even that may be pricey.

Mac mini won't power up, any suggestions

My Mac mini won't power up for more than a couple of seconds, I've tried disconnecting the power supply for 24 hours and it still won't power up. Any suggestions?

I just fixed mine today after 3 previous failed attempts to fix. While this probably will not be your solution, it is worth a shot. I too had a board that would not power, NOTHING. With a volt meter I could confirm that the Power Supply was good, and was also delivering voltage to the Mother Board at the connector.
The root cause in my situation:
The SMC reset button on the Mother Board was stuck in the depressed position (i.e. a short).
The Fix:
Pry SMC Reset button off the board with a very tiny screw driver or other such tool. It cleanly popped off the board.
The pads will remain, allowing you to still reset SMC in future if needed by just shorting them the old fashion way.

IPad mini won't power on

Ipad mini won't power on. I have tried juat now having iPad plugged in last hour. Won't power on. Have tried reset (ie home and power button not once or twice but 3x now for not only 10 sec but up to 15 seconds. ) I have checked power port to make sure clean. The iPad feels like it's getting charge as it's warm after being plugged in last hour but hard to verify if charging as no visible indication of that on screen as won't power on.
Have tried email apple but impossible to find email address on this site I have been lookin ovr an hour now. Can't take to store as nearest store is 2 hours away. I have verified still under limited warranty
Please help!

Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Mac Mini won't power on. No light, no sound, no nothing.

I left for vacation a couple of weeks ago, and shut down and unplugged my computer and peripherals. Everything was working fine. When I returned 12 days later, I plugged everything back in, but the mini won't respond. At all. Nothing. I bought a new power adapter and tried that. Still nothing. I have also tried resetting the SMC (which is really just unplugging everything and then plugging it back in). Still no response. Any ideas? Thanks for any help.

Did you get this fixed? Mine did the same thing. I unplugged it for 2 weeks and now it won't turn on at all. I have had to replaced the airport card twice, the logic board, the optical drive and just recently the hard drive... and now it won't turn on! There better be a good reason it doesn't want to work now!

Mini won't power up

I have had my Mini for two days. And suddenly it won't start up.I pull the on button, it lights up, goes out and nothing happens.
I have tried removing the battery.

Hi,
Yes, all the basics have been checked. Other appliances work fine when plugged into the surge protector and the power cord is securely attached. I don't think it's something foolish like the power cord being disconnected from the computer because the SMC was reset, giving her several opportunities to make sure it's plugged in correctly now.

Mac Mini Won't Power On -- power light on, nothing else

I will ask this again, since noone bothered to respond to my question before.
I applied the SMC reset many times. This time it happened I did not put the Mac to sleep -- I shut it down last night. This morning the problem is back and the reset no longer works.
This is a brand new Intel Mac Mini, which marks the third Mac that I bought that doesn't work properly straight out of the box that I bought. I must be an idiot for expecting quality out of Apple. Genius bars at local stores have their reservations booked up and won't accept any new ones.
What I'd like to do is -- either someone point me to a permanent solution that I can apply myself or I'd like to walk into an Apple Store and swap the Mac for a brand new one that works.
Any thoughts ?

This is (almost) strictly a user-to-user support site, and though very rarely an Apple staffer may post helpful information, it is not as a formal contribution from Apple, but merely as another user trying to offer some assistance.
Unfortunately in your case, while there have been some reports of similar behavior in other Mac minis, there has not been any clear solution found - which is why I suspect you haven't had any helpful responses. The SMC reset procedure has been suggested for this in the past, and has occasionally worked, as it appeared to do for you that one time, but generally it appears not to have helped. Indeed, the fact it didn't resolve the problem in your case after that first time suggests that it may only have been coincidental that it seemed to have worked.
There are really only a couple of possible causes as I see it. Faulty memory can cause the sort of failure to boot you describe here, and could also be complicit in wake from sleep issues too, and it's possible an external device could be causing problems too. You might try and boot with nothing connected to see if that helps, but in the broadest sense this sounds to me like a hardware failure. Macs (not just Mac mini models) do occasionally suffer wake from sleep issues, often the result of peripheral devices, but this would not be expected to also affect system boot up. Indeed, should never do so.
Typically, if done correctly, an SMC reset either works first time or not. Doing it multiple times means it isn't the solution - as you have found. It may be that your system is suffering a dead internal battery (some Mac models simply fail to boot with symptoms similar to yours) with then internal battery fails, but all in all I think Apple need to look at this problem and try and resolve it, because even if there appears to be a solution in some user-initiated procedure such as an SMC reset, unless the actual fault is known, there can't be much confidence the problem will not return at some point.
Please let us know what Apple say - I suspect they'll have you run through the usual array of troubleshooting tests, and then want to start replacing components such as the logic board, but it will be interesting to know what they decide.

Mac mini won't power on, fully boot

my mini only powers up if i unplug-plug in, but dies before it fully boots once i push the on button

Have a look at > Troubleshooting: My computer won't turn on

I have an ipad mini that won't power on. It was turned off to charge overnight. In the morning it was warm and now won't turn on no matter what I do. I've tried resetting using the power / home button combination and nothing works.

If you have owned the device, as in purchased from Apple, less than a year then there will be no charge to repair, or most likely, replace the device. If you have had the device more than a year you will be charged an out of warranty cost for replacement ($219 I think) and that is much cheaper than a new device. If you have Applecare+ then you have an additional year of coverage and the replacement will be $49 or $79 depending on when you got the Applecare.

G4 mini Random Shutdown; Now Won't Power On, Power Supply Problem?

Twice now, my G4 mini has simply turned off randomly. The first time, it eventually restarted, and all was good until today, when it did it again. This time, it simply won't power on, much less boot. I wanted to run this by someone else (no Mac people here but me) before I bought a second power supply.
What I've noticed:
*If I plug a cold power supply into the wall, and then into the mini, the mini lights up for maybe half a second, then turns off again.
*Then, leaving mini plugged in to the PS, if I uplug the PS from the wall, wait ~3-5 minutes, plug it back in, the mini will light up for 1/2 second again.
*If I then unplug the PS from the mini (but leaving the PS plugged into the PS), wait ~3-5 min again, then plug the PS back into the mini, nothing happens. No lights, fireworks, nada.
I have repeated every possible combination of plugged/unplugged mini/PS in several outlets throughout my building. It seems that if I have a "hot" PS the mini will not light up no matter what. If the PS is "cold", and has sat for a few minutes, the machine will try to boot.
All I can think is that something in the mini is tripping a safety on the PS, or the PS is just tripping on its own.
Bad PS?

It's possible the previous power supply failed in a way that caused damage to the system, or of course for another fault to have developed with these symptoms.
It's interesting that it worked, apparently properly, because that tends to suggest the fault is something new, or that you have power issues of another kind external to the Mac.
I would suggest you try and reset the PMU since this controls the power management functions of the system.
- Unplug all cables from the computer, including the power cord.
- Wait 10 seconds.
- Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
- Let go of the power button.
- Press the power button once more to start up your Mac mini.
This may not help much, but it's well worth trying.

La Cie Mini external HD suddenly won't power up

I've had a La Cie Mini HD connected to my iMac G5 for over a year, and I just noticed today that it won't power up at all. I've always used the built-in USB port, and the only other device I've ever connected that way is my iSight camera. (I noticed the La Cie went a little wonky whenever the camera was connected, so I got in the habit of shutting off the La Cie whenever I did a video chat.) I've just tested the iSight on both built-in USB ports and the camera works fine, so it doesn't seem to be a problem with the USB port. I thought it might be related to recent software updates (I did the 10.5.8 update and whatever else has come along in the past week), so I repaired disk permissions, but the HD still won't power up. Would appreciate any advice!

Hello katydid1969
(1) Can you take another look at your system and perhaps correct your problem statement?
(2) *Only built-in iSights are connected via USB*, but built-in iSights cannot be "connected" and disconnected. If your camera is an external iSight, it connects via Firewire rather than USB.
If you are having problems with Firewire iSight when connected at the same time as your Firewire LaCie drives, yours is a common problem that has existed as long as iSight. I believe that the problem relates to the differences in data stream timing between multiple connected Firewire devices.
Although adding additional Firewire cards to tower Macs (iMacs do not have this expansion capability) is reported to work for some users, the *only certain work-around that I have ever found is to disconnect other Firewire devices when using your iSight and turn off or disconnect your iSight when using other Firewire devices*.
For more info, see this linked page regarding Possible Hardware or Software Conflicts with iSight or iChat.
If your LaCie drive is connected via USB, it does NOT likely conflict with your external iSight (or vice-versa.) In that case, you will need to troubleshoot the drive, cables, ports or other USB possibilities.
(3) If your problem does NOT relate to Firewire devices, we will try to offer other suggestions in response to the details in your reply.

I have a 2011 mini that won't power up. The apple on screen comes onn then turns into a circle with a line in it. Any way to fix it?

I have a 2011 mini that won't power up. The apple on screen comes onn then turns into a circle with a line in it. Any way to fix it? It is running Mavericks on a 1T drive.

First thing, see if it will boot into the Recovery Partition: Hold down Command R at restart.
If it boots up there, then it's likely that the hard drive has failed, or simply doesn't have a working system.
If it doesn't boot up there, then it's likely to be some other part of the hardware.
If it is the hard drive, then this can be replaced. You can find videos showing you how to do this on sites like ifixit.com.
Then you can just restore all your data from your backup. You do have a backup, right?

Mini ipad won't power on

My mini ipad won't power on even when completely charged.

Try resetting it. Hold the on/off and home buttons together for about 10 seconds till the Apple logo appears.
Please make sure it's completely charged when trying this.

My Mac Mini won't start. The Power light blinks continusly (not pulses)

My New Mac Mini won't start up. I bought it online from J&R a week ago. My monitor says "no input detected" and the power light blinks. I recently fed it the gray mac os x install disk one, which it won't give back. Holding the mouse button when it turns on doesn't have any effect. So now i can't put a disk in or start it up.

Welcome to the Apple discussions.
No video with the power light blinking once per second means either bad or no memory. See this Apple note: http://docs.info.apple.com/article.html?artnum=303083 . Specifically, below is from that note:
If the computer detects no SDRAM (Synchronous Dynamic Random Access Memory, also referred to as RAM) or the RAM installed does not meet the appropriate specifications, the screen will remain black but the power LED on the front of the computer will blink once per second to signal the error. This error condition may be due to physically damaged RAM, installing the incorrect type of RAM, or not having RAM installed.
Has it ever worked since you got it? If not, you should call J&R and tell them they sent a dead on arrival system, and ask for a replacement (ask them to send a will call tag or prepaid label to send the non-working machine back).

CFP-DIO-550 Won't Power Up

I just installed a new cFP-DIO-550 module in my compact Fieldpoint system. The unit was tested yesterday and performed perfectly. Today, upon booting up the system, I notice that the DIO-550 module won't power up. When I connect power, all the status LEDs on the module flash dimly, then go out. All the other modules are working fine. I know there's a firmware issue in the knowledgebase similar to this one, but it only applies to Rev. D and earlier, while mine is Rev. E. How can I resolve this issue?
Thanks,
Martin

Martin,
Suggest you move the cFP-DIO-550 to a different slot on the backplane and double check any power supply connections/voltages to the module. If it still doesn't work, it's most likely a case of infant mortality and you'll need to contact NI.

Mini won't boot when VGA is attached to KVM -- help!

My mini (Core Duo 1.86MHz, all updates installed) is attached to a Belkin Pro2 4-port KVM (F1DA104T). I've read comments about issues with KVMs being picky with the mini, but the mini won't even completely boot when the VGA cable is attached. I've used this KVM with other 10.4 Macs in the past (G3's, G4's), so I didn't expect problems. The monitor is a Dell 17" LCD (E173FP), which is fine when attached directly to the mini. I've also tried another LCD (different manufacturer) with same results.
The mini boots and I first see the gray screen with the Apple logo, followed by a light blue screen, and that's it. The finder never comes up, and I can't even SSH or VNC into it -- just the blue screen. Once I remove the VGA cable (only video - the keyboard and mouse are both still connected), it will complete the boot and launch the finder. If I boot with no display attached, or attached directly to the LCD w/o the KVM in the path, but then attach the mac to the KVM, I see the display for about two seconds, and then the monitor heads into power save mode. When I VNC into the mini to see what's going on, it's detecting two different displays; when the cable is attached but the KVM isn't on the mac's channel, it's one thing. When I switch over to the mac's channel, it's like I'm plugging in a different display. In any case, the computer is putting out 1024x768x60Hz, which is well within the specs of the monitor and KVM.
I installed SwitchresX and under VNC retrieved the DDC info. Here's what I have for when it's plugged into the KVM and on channel:

So far, I'm stumped. This is a $200+ KVM, supposedly better than many of the cheapies, with listed Mac compatibility. Neither Apple nor Belkin wants to take ownership for this problem. If anyone has any tips on where to look next, I'd be very grateful!
Thanks!
Jeff

Hi BSteely,
Thanks for taking the time to look into this.
The blue screen I see is definitely not being generated by the LCD - it's coming from the Mac. It's coming up just after the gray Apple logo you see when booting. Normally you'd next see the finder pop up, but that never happens as long as the KVM is plugged into the mac (and it's only the VGA connection which is doing this, since the same thing happens with the keyboard/mouse unplugged from the mac). Once I remove the VGA cable, it continues to boot normally. If I hookup the LCD directly to the mac, it also boot normally.
Sorry I wasn't clear about VNC. I'm not seeing two displays at once, I'm seeing two different displays -- one when the kvm is on the mac's channel, and another when it switches away. Funny enough, I'm getting MORE resolution choices when I'm not on channel. The DDC info I posted above is for when I'm on channel.
Jeff
