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.
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.
Sometime when I stop using my MBP for a minute or so, the screen goes black and won't wake up. I can see that the lights are on the keyboard and it's running but won't wake up. I will have to hold the power button down and then restart. Does any one know how to fix this? It's starting to do it more and more ofter.
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:
Got a tricky one here: powerbook G4, 1.25ghz, 1GB RAM (2x512), 80gb HD, APX, 15" LCD, serviceable battery, SuperDrive, OS: 10.4.11. It was brought to me with a boot problem: Computer turns on, gives the start up sound, backlight comes on, apple logo shows, spinner spins... then you get the dimmed screen, large option icon and "You must hold the power button and restart your computer": a kernel panic. I've seen this a few times before and the last time, I fixed it with a new hard drive and the removal of RAM from a bad ram slot.
What I did was: 1) Replaced existing 80GB HD with a backup 30GB drive. Then booted with a Tiger CD (the computer won't start with my disk warrior cd, nor with a tiger DVD). I was able to install Tiger and restart the computer. But the airport card doesn't show up. I tried a known good airport extreme card and this too has not shown up. 2) I hooked up the 80GB drive to my PC via MacDisk and checked it. Sure 'nuf it had loads of problems. MacDisk went through and fixed it (I'm not sure what the problems were as I'm new to MacDisk and don't know what it's looking for and fixing when it does). 3) With the computer running the 30GB known good HD, I started having the same kernel panics so I removed the first RAM chip (512MB) and tried to reset the PRAM.... here's where it went wonky. (I know, only change one thing at a time...) 4) As I said I tried to reset the PRAM (Option, Command, P, R, at start up). While I can get the computer to not boot, it won't restart. I don't know if this is just unique to this machine. Next I tried to reset the NVRAM and again got nothing. The screen wouldn't come on at all. After about three or four resets, the computer did start in Open Firmware mode. I reset the NVRAM from there and restarted (reset-nvram, reset-all). Still nothing on restart. 5) After trying to start it 15 times like this, I swapped the bottom RAM card to the top slot and removed the airport card (again, I'm stupidly trying to change two things at a time). BAM, computer boots... I put back in the 80GB drive that's been "fixed" by MacDrive and BAM, that boots fine too.
So then I put back in the airport card and it will boot, but won't recognize the airport card. I've re-seated it about a dozen times and have used terminal cleaner on the card and on the socket for the ribbon cable from the card slot to the logic board. As it sits, I can't get the airport card (either of the two) to show up at all. I did realize that the open firmware did reference a problem, but I forget the code now and when I looked it up, the references were to a failure of the airport card, but there were also more general references, so I can't be sure.
I'm thinking now that it's the airport card controller on the logic board, the bottom RAM slot and a corruption of the hard drive. Yes, there was a history of moisture into the device and I think a drop in it's past too. I'm the Mac repair technician for the people at the local bike shop, so I get to trade my repair work for their bike repair work. The problem is that they ride their laptops like their bikes, hard and greasy. I'm really wondering about ways to get the airport card back up and running. Or, baring that, a good card-based wireless adapter that I can slide in.
My MacBook Pro froze while I was using it, so I shut it down manually with the power button. When I turned it on again, the screen with the Apple came up and the small spinning wheel is showing, indicating that it is loading, but it won't going any further than that, so I can't start it up or access any of my data. What can I do?
We're not used to having the computer's power button on the keyboard. Occasionally, when trying to hit Delete, one of us turns off the computer power. I'm wondering if there is a setting (I really don't know my way around macs or I'd check myself) that can trigger the shutdown only after the power button has been held 3 seconds or more. This would prevent those accidental shutdowns.
My Macbook pro is not booting properly. When I start it up, it goes through the normal process and gets to a point where a screen comes up telling me: "You need to restart your computer. Hold down the Power button for several seconds or press restart now" This happens every time. I tried to start in safe mode and holding down the option key and selecting the mac partition. Neither would work.
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.
im new here and im a little unsure where to post about my macbook, But i hope this is the place. Anyways, i was wondering if its possible to toggle the fn button, cause im a flash animator, and its pretty anoying that i have to hold fn down to create a new keyframe.
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 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 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?
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.

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 macbook has developed a problem where when the lid is shut and the power is connected it wakes up from sleep and then goes back to sleep and repeats this process every 30-60 seconds.
What's weird is it doesn't wake from sleep and get stuck in this loop when�the lid is open and the power is connected and I select sleep from the Apple menu�when the lid is shut and the power is NOT connected and is running from the battery
I recently updated my mac to Snow Leopard and put in a new HDD and since doing so the problem has been occurring.
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.
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.
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.
