MacBook :: Unibody - Won't Start When Press Power Button

Jun 13, 2010

my brother is having a problem with his unibody MacBook that he bought just a few months ago. It won't start when the power button is pressed, the sleep indicator light turns on and that's all. There's no start up tune, and nothing appears on screen. I had a similar problem with my MacBook Pro. I was told that the logic board needed to be replaced due to too much dust or moisture. Could this be the same problem? and has anyone else here ever had the same problem?

IMac PPC :: G3 Will Not Start Up And Nothing Happens By Pushing Power Button?

Apr 9, 2012

This morning when the power button is pushed, nothing happens at all. The button does not light up. The computer does not start.I checked the power cable. I took it out of the computer and put it back in. (I did note that the plug looks a bit darkened but it does not smell burnt.) I tried it in a different outlet. Same thing. It won't turn on.I can't recall if this iMac is a G3 or G4 and I can't find my documentation to let you know. But I don't know that it matters which G it is. It is the old special edition grey iMac and has been working for us for many years.Is this the end for this iMac? Could it be something that is simple to fix?

IMac (Intel) :: Cannot Put To Sleep Using Power Button Since Mavericks Upgrade 10.9.4

Aug 22, 2014

As the title states, I can no longer put my computer to sleep using the power button. I have to put it to sleep using the mouse. I miss the convenience of the power button. The window for energy saver is not like the display in support, it is missing the "Allow the power button to put the computer to sleep" option. Very strange. I am running an older desktop (2009) with Mavericks, fully updated. 10.9.4

PowerPC :: IBook G4 - When I Press Power Button, Power Fan Comes On, But No Picture Shows

Feb 10, 2008

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.

Power Mac G5 :: Won't Boot Up Blinking Power Button After Adding Ram

Dec 6, 2007

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 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.

PowerPC :: Making Power Button Shut Power Mac Off?

Oct 7, 2006

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.

Mac Mini :: Restart Message - Hold Power Button / Press Restart Button

Apr 29, 2009

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.

MacBook Pro :: When Pressing Start Button There Is A Delay

Dec 1, 2014

When I press the start button there is a delay of 3-4 seconds before the computer turns on and the sign in screen appears. Then when I shutdown it takes up to 4 minutes to actually turn off the screen.

I also ran a diagnostic check and received the error code HDD/11/4000000:SATA (0,0)... What I do next?

MacBook :: Turn On It Without Using The Power Button?

Jun 11, 2012

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.

MacBook :: Power Button Always Pressed?

Jun 29, 2014

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.

MacBook Pro :: Won't Shut Down Unless Hold Power Button

Jun 17, 2009

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.

MacBook Pro :: Power Button Not Working After HDD Replacement?

May 22, 2010

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.

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 :: Does Not Shutdown Even When Holding Power Button

May 7, 2012

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.

MacBook Pro :: New SSD Installed - Power Button Not Working

Jun 28, 2012

After 1.5 years of use, my hard drive suddenly failed. This was later confirmed by Apple Genius Bar.So I purchase a new SSD from OWC which was instructed to be compatible with my laptop model (MBP 13" early 2011).It arrived today and I did the installation carefully and successfully.However, after putting the back panel back in place I was unable to power up my laptop.

It was as if the power button is not working.Then I opened up the back panel one more time to realise that every time I click the power button (turn on), the fan started running, this can only be stopped by pressing the power button and held it (turn off).I tried placing my old hard drive and it doesn't work as well.I tried reset the SMC by holding power-shift-option but same result.

MacBook Air :: No Backlit Keyboard - Power Button Eliminated

Oct 20, 2010

Note the F keys on the 11 inch, and the new power button. What's missing? Also note the lack of the word 'backlit' in the descriptions for either machine. Both machines have the same keyboard, just to eliminate the power button in the name of aesthetics.
