I have Mac Mini 1.5 solo that work very well for me and my son untill we updated the EFI 1.1 a week ago and never booted back up. I call apple and was told bad hardware maybe caused by update they send me to a Apple store to get it checked but there they said it was the power button not the flash. I had it plug in to the wall the hole time at home but when i took it there it booted as soon as he plug it in so he shut down and it did not boot, he unplug it for a few seconds plug it back no good with button but did boot a few second by itself. I replaced the button my self for a few hunder less then what Apple Was asking for (160.00 less). Still not luck. I feel i got screwed by Apple on this. Has anyone seen this and how it fix.
I added 2 sticks of 512 to my power mac g5 1.6. I had ahard time getting the computer to see the new ram, but finally was able to kinda get it working after zapping the pram. However my computer only saw these 2 sticks as 256, odd. So i attempted to troubleshoot the problem. I tried just installing the new ram, but the computer wouldnt boot. I tried a few different combos with the other 4 sticks i had, but nothing. I put the old memory back in, and still nothing. The power led looks to blink once every five seconds or so. I tried pressing the pmu reset button, but still the same out come. I also tried taking out the battery, nothing.
I have just shipped my Mac Mini to its new home and I've had reports that the panic error is appearing on boot up: "You need to restart your computer. Hold down the power button for several seconds or press the Restart Button." This screen appears on the blue window just after the grey apple screen has disappeared and does not get as far as the desktop at the same point each time. We have tried to reinstall mac OS from the original install disk but holding the "C" Key or the "Option" Key down on restart doesn't boot from disc. Is there a way you can view the Kernel Panic log before you boot into Mac OS so we can try and pin point the source of this problem. I'm wondering if this could have been the result of the shipping that has caused some hardware to come loose.
I'm running a late-2008 Macbook Pro with OSX Mavericks. I installed a new battery, and the computer will not recognize it. I've heard that I should reset my PRAM and NVRAM. I have already reset my PRAM, but my problem continues. I have removed the battery/pressed the power button for 5 seconds, held the power button down during boot,I cannot access the open firmware.
I am having lockup issues with my new Mini. I changed the RAM to 3gb and a SSD. boots fine but completely locks up after a period of use. Only way to cure it is to force reboot via power button. Anyone here has the same issue or know what I should do?
The only gripe so far with my 2011 Mac Mini is the power button on the BACK of the computer. Really? Everything else I can turn on while sitting in my chair, but I have to get up and reach around the mini to turn it on. I guess I'll have to get an under desk mount and put it close to the front of the desk so I can reach it. Â
Was Apple worried LaCie was going to sue them over design issues if they had a single power button on the front?

My 1999 PowerBook G3 "Lombard" does not start when I press the power button. Is there a way to force it to start without it, or do I need to get a replacement button?
i accidentally hit the power switch on the wall during an upgrade (might even have been a firmware upgrade, I didn't really look at what was going on). Anyway, now it hangs on the silver Apple logo screen with a spinny wheel on reboot. It's only 3 months old, it's the $599 model.Â
What to do? I see that you can download firmware restoration disks but they appear to be limited to earlier versions of the Mac mini.

I have a new MacMini without the optiocal drive. This is a computer that someone tried to put Linux on and left it was a 100gb partition for the MacOS and the rest for the Linux installation. I want to get it back to one large partition.Â
I know that I need to get the computer to boot from something else because the Recovery partition is on the HDD. To that end I have tried to boot this from an external USB DVD-RW drive and when it starts to boot from the disk it reads the DVD and then goes to the 'circle/slash' screen. I then made a USB drive bootable and restored the dmg file for my Lion disk to it and tried to boot from that. It shows in the options and then immediately goes to the 'circle/slash' screen. I tried to flash the PRAM and got the same result. I tested both items on another MacMini and they work. The test computer was a previous model with the optical drive.Â
I have a iBook G4 laptop and there seems to be something very wrong with it. It started a few days ago just randomly. I was reading something on the internet and the screen went black on me, but the power was still on (I clicked CAPS LOCK to see if there was power). I then proceeded to push the power button and the power went off. When I pressed the power button again to turn it on, it made that internal noise it always makes and then the fan came on, and wouldn't turn off. There was no picture on the screen at all. Completely dead. But there was power, because when I clicked on the CAPS LOCK, the light came on). I tried pressing on the power button for at least 15 seconds and even went as long as a minute, and the power didn't go off.
I had a weird issue this morning. I started computer and it did not make the chime sound, it didn't do anything at all. I disconnected it from the extension cord as well as all the peripherals attached to it and nothing. I tried a different start up disk and again there wasn't a sound. Then i unplugged it and reset the SMU on the mother board and air sprayed the computer to remove all dust. Then plugged it back and it came back on.

I'm using a B&W Power Mac G3 with 512MB RAM and OS X Tiger for a SMB file server (with 5 users) and a USB printer server. Everything is working good, but I have a problem.
It doesn't have a monitor or keyboard/mouse attached normally (I can configure it via VNC). The problem is that I would like to be able to turn the machine off when it's not needed (like at night sometimes, days when I won't be home, etc.). I would like to just hit the power button and have it turn off, however it puts it to sleep instead.
Normally, sleep would be fine, except on the B&W, the fans still run, just the HDs shut off, so it's still noisy as heck.
Is there a way to make the power button shut it off? If not, any other easy methods of shutting it off you can think of? Via VNC won't cut it, as my dad needs to be able to turn it on (not a problem) or off as well.
i just got my new imac 2 days ago. I was wondering is there another to turn on the power without pressing the power from button? (cuz i remember u can power on from the keyboard b4)
While uninstalling Safari 4 beta it freezed and after 15 minutes of waiting I made a forced restart. Now Mac mini shows the grey screen and won't boot.
What I've tried:
- Disk Utility from restore DVD - fsck in Single-User Mode - resetting PRAM - resetting PMU
I still use this old PowerMac G4 (hopefully Apple builds a new MacPro soon!) and when not using it, it is in sleep mode.Unfortunately my cats like to touch the keyboard, thus waking up my Mac.Is it possible to wake the mac only by pressing the power button?
My Macbook Was On And Working And I Tried To Hit The Power Button To Turn The Macbook Off And It Would Not Work....so I Shut It Down Using Computer Shut Down Under The Apple ....now It Will Not Turn Back On......it Has To Be The Power Button Itself....is There Any Where I Could Buy A Replacement Power Button? And Is There Any Other Way To Get It To Turn On Without Using The Power Button?
After leaving machine on all night as I usuaaly do in the middle of a project I came in this morning to find power button blinking no -stop. No images on displays.Have reseated RAM (original 2G from Apple and subsequent modules (4x2) from OWC) twice and no change. No peripherals connected and no change.

I turn off Imac, using apple menu. Sometimes the power button will work to turn it on, other times it won't. Been to 2 authorized dealers, they can't find problem. Sometimes jiggling or shaking computer will allow me to start using power button. Sometimes I open up case, plug and unplug everything, and then power button will work. Never know when it will work or not. Power button has had continuity check. It checks fine. Power plug is fine, outlet is fine.

I have a white 2008 model MacBook. Due to some unfortunate tampering with the circuits under the right command key on the built in keyboard, a lot of the keys and the power button are now effectively dead. I'be ordered a replacement top case, but was wondering if I could, in the meanwhile, somehow turn the laptop on. I'd prefer to do this without opening it up, though I could if that's the only way. Â
I read in another thread, can't find the link now, that disconnecting the battery, connecting mains, then connecting the battery would turn it on, but that doesn't seem to work for me.

my power button is constantly pressed. While I was using my computer, the screen got black automatically after a few seconds.After I pressed ESC in order to get back to my desktop, after another few seconds, the window asking if I want to shut down / log out / reboot appeared...When I'm trying to boot my Macbook, after a few seconds, it automatically shut down, without warning, as if I was pressing power button for a few seconds to force the shutdown.I can boot if I remain a keyboard's touch pressed during all the booting process, like Maj, or Alt, but as you could imagine, it's not really easy to use a computer with a keyboard's touch constantly pressed....Â
By the way, I won't go to the Genius bar for a few reasons, first, this Mac is 5 years old, so I'd prefer buy a new laptop instead of paying a few hundred bucks in order to change pieces of this old Macbook, secondly, I don't have an Apple Store near my location.
I have brought the 21,5" iMac 1 week ago. I just chosed the preconfigured model. But i have had some problems with it.When the computer has been to sleep for some hours, it wont wake up with click on keyboard or on the mouse. I will have to use the powerbutton, where the computer then comes with a error, but it starts up.
I know I can get the bulk of it here: [URL:..] But is there a controller board? I can't find any documentation on this thing. I want to use it for a PC. Making an acrylic top is no problem. Just looking for pin-outs, dimensions, and maybe some pictures of someone else dissecting one.
I was just wondering if anyone knows how I can remove my eMacs power button, the one that you press to turn the computer on. I kinda wrecked mine and I want to "pop" it out to have a look at it. Looking at replacement costs they are like 50 bucks so I need to try what I can before I fork out for a new one.
This is a mystery to me. Long story but the gist of it is that I found if I hold down the power-button on my iBook while it's off it goes into some weird mode. i.e. fan spins, disc spins, sleep light flashes and a tone comes from the speakers.Is this some sort of hardware test mode? Is it going to blow up? Is it resetting something?
Does anyone know if there's anyway to turn on an aluminum powerbook without the power button? I mean is there any keystroke combination that can turn a powerbook on?
My 15" early 2008 MacBook Pro won't shut down unless I hold the power button. I have done extensive searches and have done the following and the problem still persists. I have pulled the battery to reset the SMC or whatever it is called. I ran disk utilities and repaired the permissions. I deleted unnecessary files in the preferences folder...... still no go..... in fact it won't load software updates because it gets hung up.... then I have to force quit it by holding the power button..... I am at a loss.
