MacBook Pro :: Will Not Turn On Or Respond To Power Button
Apr 17, 2012
My MacBook pro (15" unibody, non-removable battery) will not turn on. The battery claims to be fully charged. The computer will not respond to the power button in any way. I had turned it on previously by draining the battery completely of any charge (draining power, then pressing and holding down power button for 60 seconds). When this occurred the computer booted up and ran fine. However, when I closed the lid, it turned off immediately, never to return. I'm wondering if this is a problem with the battery, or if it's a problem with the logic board.

MacBook Pro, Mac OS X (10.7)

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.
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.

1.turn into black screen after running for about 15 mins, but the system is still running because the keyboard is still functional. After reboot, i record the log as below, it shows that it is a GPU Panic.
2. display would not turn on after pressing the power button but can still hear the apple start up chime and the system keep running with the screen off.
3. after erased the hard drive and re-installed Mavericks. Under a new installed system, it can run normally for about 1 day, after that especially after a shut down or restart, the problems above came back.
I am currently working in Thailand but I have no plan to go back to the US in a short period of time. I brought the laptop to the local apple service, they said it is certainly the logic board or GPU failure and the parts need to be replaced. The cost of the replacement is around half of the price that I paid for this laptop.

Just got a replacement imac 27 stock C2D yesterday for a defective one I had earlier, however, I couldn't get this new one to turn on till just a few hours ago. I just figured out the power button needs quite of bit of pressure to turn on. Seemingly just pressing it until it clicks isn't enough. Should this be looked at or is this normal?

So I'm having issues with the computer not waking up in the morning. I guess it goes into a deep sleep of some sort and I have to hold the power button twice to turn it on, and get greeted with a computer experienced a problem message on login.
The most recent log in the system diagnostics is titled:
aosnotifyd,diskarbitrationd_2014-08-21-184310_MacBook-Pro.shutdownStall
And the brief details are:

I have a G5 dual 1.8 power PC...Bought some ram put it in & booted up. Then a red light came on the logic board behind the power button. The machine wouldn't turn on....I called apple care & we rearranged the ram, now the red light is gone but my system still won't boot up. The white power light blinks every few seconds... the apple store told me sorry can't help because your machine is vintage. Even if my logic board is fried is there a place to buy one on the cheap?

So this morning I woke up and went to press the power button of my Macbook, but nothing happened. I noticed that there is no white IR light and the fan doesn't respond. I checked the battery, it was at full. The power cable was also green when i plugged it into the Macbook. However, it still wouldn't turn on.
Just a general comment, I use the Macbook as a printer server and to browse the internet, so nothing intensive is forced onto the Macbook.So then I tried resetting the SMU, didn't work. I tried turning it on with only battery , and then with only power source, both didn't work either.I have never spilled anything on this macbook, never dropped it, smashed it, or abused it in any way. However, it is 2 years old and I never bought Applecare (Usually, if something is defective, it will show within the first 30 days). I assume it's a logic board failure, and it's going to cost around 700 to fix (which i'd rather just get a new macbook).
I was wondering if anybody know of a reason why the logic board broke, or if there is any remedies that i haven't tried yet?Also, I'm thinking of pawning it off on ebay and then save up and wait for the Macbook Pro refresh. Does anyone have an estimate on how much I can get for a broken Macbook (screen is fine, 4gb of ram (i might replace it w/ 2gb instead) 250 gb HD (might replace with 80gb HD instead), 2.0 ghz c2d (prbly useless cuz the logic board is fried)

I have a new MacBook Pro at the new job. All software is up-to-date (10.7.3).
In all apps, when I click on the PRINT button, nothing happens. I opened the PRINT QUEUE and there's no record of anything being sent to the printer. I've gone and done the RESET THE PRINT SYSTEM process. No change.
In a Windows network environment, printing over network. It seems to not have anything to do with the network, though, as I can see the printers and get them set up, and I get no error message. The PRINT button is just...dead.

So everytime I try to turn my macbook pro off by clicking the shut down button it does the usual turning all software off and then going to the desktop with the dashbord going away and the little circle coming up but it just stays like that forever until I force it off by pressing down the power button. What should I do? I just got this laptop around 6 months ago

I have had this problem for the last year but have worked around it by manually shutting down the system. My mac will not shutdown on command or restart during a program update or by going to the apple and trying g to restart. I have tried on numerous attempts to find a related topic but there is none to my knowledge.

For people to start getting use to not having a button with the track pad and only learn to use multitouch like how it is on iphone?I realize now that i turn on trackpad clicking that i just about NEVER use my think click button. Also the click button is so small i'm thinking they did it on purpose so it'll force us to use multitouch.

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 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 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 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 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 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....
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.

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.

Ok. so my MBP was working 2 days ago and I went to Fry's to replace the HD with a 640GB model thinking larger storage - win. Replaced in and the orange ribbon cable got disconnected between the keyboard and the logic board. Went frantic and after a visit to the Apple Genius, they plugged it back and thought i was fine. Nope, and now the unit won't turn on. Plugged it in and got the green light and battery charges, but the MBP won't power on. I made sure the HD was plugged in securely, the orange ribbon connected fine, and the power button cable was secure. The drive worked fine as I did a superduper transfer of the old data to the new drive the night before the crisis and it worked fine.

Today I started to watch a video from a news site (probably using flash) and the computer started to slow down very much so I thought firefox had crashed. Then I force quit it and waited about a minute or two hoping the computer would get fast again as usual but it did'nt happen, so I tried to log out and nothing happened and then I tried to shut it down by clicking the power button and clicking in shut down.
Right after that, the computer started to shut down or log off (it was still very slow) and something happened it stopped in the middle of the process and displayed a blue screen (the same colour that appears when you connect another monitor to the mac). Then I thought of using my last resource: holding down the power button until the computer turned off but again, nothing happened.
