MacBook Pro :: Turns Off During Boot?
Jun 26, 2014
I have a 13-inch, Mid-2010 MacBook Pro running OS X Mavericks. I was using it near a bathtub, when a moderate amount of water spilled onto the keyboard. I immediately dabbed out most of it, and put it upside down for some time. It was running then, with all the keys and trackpad working fine. t turned it off, and tired turning it on after half an hour. Nothing. I decided to keep it switched off for 7 days, during which I would open the lid every now and then to find vapor on the screen from the keyboard which I would wipe and close again.
I turned it on when there was no vapor spotted for 3 days. I plugged it in after 7 days, to see that the battery status indicator was erratic. It turned on with a sound from the SuperDrive (the usual click). There was no startup chime. A few minutes later, it turned off. I decided to reset the PRAM and SMC, and I realized that I can get to my account window successfully (and type a 22 letter password) as long as I keep any key pressed throughout bootup (option, command key, etc). I have tried many times, but it just turns off with a "nik" sound. I haven't backed up, and I have about 270 GB of important data stored that I CANNOT lose.
It's 250GB drive crashed in December but it was replaced with a 500 GB and has been running smooth until this.

Late last night, I ran into some problems with my iBook G3. It's the 700 Mhz model, with 384MB of RAM. Nothing else special in terms of hardware config (unless an Airport card is special). OS X 10.2.8.
Basically, the computer seemed to hang and I did a hard reboot, and upon starting up I got a folder with a flashing ? .
I can't seem to find my Install disc 1 to run Disk Utility or just boot up - hopefully I will find that when I go home tonight (or maybe I left it at my parent's place), but I checked using the Hardware Test CD and it didn't detect any problems.
I am having problems opening the CD drive, so I've had to open it using a paperclip. Sometimes it doesn't appear to be using the CD.
I also have run the Micromat test CD that came with Applecare (of course this machine is almost 4 years old so that's finished...) and it detected a problem with the Read Buffer last night, but then I guess the battery ran out while it was on the last test.
This morning, I ran the Read Buffer, Write Buffer, and Volume structure tests and the first two passed very fast (unlike last night), but the Volume Structure test failed. I'm not surprised since I've been aware I have issues with this before. I tried to repair before going to work but at one point it seemed to hang so I gave it another hard reboot.
Last night, I would sometimes get the apple logo with the spinning "clock", and sometimes I would get the ? but it would never get to the login screen.

So I've got a powerbook G4, thats 8 days past its warranty. Conveniently, it now won't turn on. It won't wont boot from CD. If I turn it on, I get a gray screen that usually just turns my computer back off, if thats not the case I get a screen that shows the finder icon and a question mark and then turns off.
All it will do is boot into open firmware mode. Currently the install disc is inside of it and I've tried booting the cd using "cd:, bxi" and "dir hd", and it can't open both. Does anyone know how to wipe the HD, and start the installer using firmware? Otherwise, I think I'll have to take out the harddrive and plug it into an external case and then wipe it.

1.- The imac turned off by it self.
2.- I tried to turned on pressing the turn on/off button and it did not do anything.
3.- I disconected the computer form the wall and wait for some minutes, and it did no do anything.
4.- After about 20 minutes i tried again and turned on by pessing the on and off button.
5.- The imac turned off again and disconected form the wall and conected to another electrical contact at the wall, adn it did not turned on. i wait for some minutes and turned on again, but after about five minutes it turned off again.
6.- I left the imac connected to the wall for a couple hours and i tried to turned onn by pessing the on/off button and it did not turned on.
7.- I left all night connected form the wall and tried to turn it on this morning and it did not turn on.
8.- This time, I only disconnected the imac cord form the back of the computer and left it for a couple of hours, then I concected and turned on
9.- All the times that the computer turned on it started like a restart and no announce or windows appear telling me about an error or something like that.
10.- One of the times I touched the computer at the back and felt it hot, not too hot, but I do not how normal is.
11.- I can feel some very, very little air at the back form the vent.
What do I hve to do? What kind of tests can I do to know if the computer's an is working ok?

I have so far had a few instances of this phenomenon w/ my 15 mo. old Mac. First, when charging my Mac at night in off-mode, it will occasionally turn itself on at some point evidenced by the power-on when it's opened. Then,I have had one instance of a shut-down by itself during use. It restarted w/ no problem. Next, the computer turned itself on with the cover closed and the computer had been off all night. I heard it start up, so I am sure. I do have AppleCare if I need to take it in.

This has happened twice not. I'll be using my MacBook and it will have around 40-60 minutes worth of battery left, around 30% or 40%, and it will just shut off. No warning at all, it just turns off as if I've pulled the battery out. I plug it into the mains and turn it back on and it says I have at least 30% battery left. Is my battery dying?

I have had my MacBook Pro since May 2007. It has been working fine up until a few months ago. I will have nearly full, or fully battery and the computer will turn off, and will not turn back on unless I plug the charger in. If the charger is unplugged for 5 minutes, the computer completely shuts down. So basically I cannot use the computer unless it is plugged in. It is starting to become a pain because sometimes I need it when I am in a place without an outlet.

I have just recently noticed that when I put my computer to sleep the Apple logo flashes every few seconds and that it gets out of sleep mode by itself. When I went to turn it off it quickly turned on again. It happens whether it is connected or not. I have tried a few things and this [URL] but nothing has worked. I bought this computer last December, so it's still under warranty. I cant reset the SMC because the computer does not remain turned off, when I shut it down it automatically turns on again. Also I did a hardware test, both the short and the long ones and it said that there where no problems. I am a college student and I can't afford another computer so I am a bit scared that this is going to damage it.

I have a late 2006 Macbook pro, it has problems turning on. If its cool it will turn on just fine. If its warm, you have to wait 15 minutes for the MBP to cool down. Is this a logic board issue? It seems so.

The volume on my macbook pro will randomly turn itself on. The volume image shows up and it then turns all the way up and keeps clicking until I hit one of the volume buttons. But it will do it again about 30 seconds later and it keeps repeating this process for days. Shutting off the computer doesn't do anything. It does this randomly, it may not happen for months but then when it does happen it can go on for days if not weeks.

I have my MacBook hooked up to a pair of external speakers (M-Audio AV40, for those interested) and I can hear a slight click when the computer hasn't played any sounds for a certain amount time (about 30s to a minute). My PowerBook G4 never did this, so it's not the speakers.

At least, it seemingly randomly turns off. I can be surfing the web or whatever like normal, but then after a period of time the monitor goes black. I can see that the computer hasn't shut off, but it's as though the computer is on its lowest brightness setting. It can be temporarily fixed some times if I lower the brightness all the way via F1, then put it back up, but if it goes up more than 3 or 4 boxes it goes black again.
It also goes black if I were to move the monitor any time during this whole thing. I've heard things like an inverter cable and board, but I have no idea what's going to fix this. This is my only computer, I use it for all my school work, if it breaks permanently I'm screwed.

I have a 3 months old MBP SR and recently I have noticed that the charge light on the magsafe adapter turns off after a while. It used to stay green when the laptop was charged but now it turns off. It usually happens when I put the computer to sleep. After a while the charger light turns off. Not a huge issue but I was wondering if other people were seeing something similar and if there was something I could do to get the light back on (I think it looks nice).

I've been digging around for a couple weeks now for information on what may be happening to my MBP. I've tried numerous solutions, but don't seem to be able to get the computer to STAY ON. Here's my story:
A couple weeks ago, my room mate was using the computer. She closed it to put it to sleep, and left it on my bed. When I went to turn it on, the screen was completely black and the indicator light on the open button was a steady grey. The computer was so hot it was painful to the touch. I unplugged it, hard powered it off, and let it sit, thinking it was an overheating issue.
Since then, the damn thing won't stay on. Initially, it would intermittently just shut off. When that happened, sometimes I could boot it back up, and other times it would sound like something was whirring in the background, but the screen stayed black and the indicator light stayed solid grey. I installed SMCFan and istat to monitor/control the temp and fans.
I noticed somewhere along the way that there seemed to be some connection between episodes of shutting down and the power cord (as in, if it was jostled, the computer shut off)(I should note that my battery is at about 15% health with a full charge). Then, that power cord died (no green/amber indicator light and no connection detected). So I bought a new cable, and set about trying to fix the problem again.
Next phase, it seemed that if I moved the computer, it shut down. So I did some of the recommended fixes. I deleted the power management plist, I changed the settings to never put the computer or the display to sleep, and I turned off the quick-motion sensor that stops the hard drive. I also reset the SMC settings.
This seemed to improve the situation a little bit, insofar as now instead of getting a shut down, I am now getting complete reboots that only *sometimes* lead to the blank screen and steady grey indicator light. This does happen more frequently if I move the computer, but it can also happen if I simply leave it to run. In fact, if I send the computer into sleep-mode, and close the lid, I'm practically guaranteed a reboot.
So, then I reset the PRAM and did the hard-reboot (ctrl+opt+power) and reset the PRAM again. I am currently running Rember to test the RAM, but I'm not sure what to look out for when it finishes, or what I should do about it.

So, okay, I happen to have an 13-inch MacBook (aluminum). Before I move on to point out all the problems I'm having, I guess I should point out I bought it from BestBuy, and open box. Don't worry, no need to scold me, I've learned my lesson.
What happens with it is that it freezes at random. Completely. It doesn't do a thing. I can't move the mouse, and nothing on the screen moves. This forces me to do a hard reboot. Sometimes, when that happens, when I turn the computer back on, airport doesn't appear. I check on networks, and it won't turn itself on. I have to turn off the computer and turn it back on until it decides to appear.
Apart from that, there are times where Airport randomly decides to shut itself off. At the top, I can see the Airport icon but the signal lines are gone. It's completely blank, as if I had turned it off. If I try to turn it back on, it doesn't do it. I click to turn it back on and it doesn't do anything.
I took it to BestBuy since I have a warranty with them. First time, they said my harddrive was faulty and they'd replace it with no cost. Fair enough. When I picked it up a week and a half later, the problem was still there! I left it at BestBuy again, and the guy told me that he can't find a problem with it. That he had run all the tests and that my computer passed them all without a problem. He checked everything, and yet the problem is still there.

I just bought a refurbished macbook pro and at first the screen wouldn't turn on when I started it up, the little sleep light was on though. I pressed and held down a key for a few seconds right after pressing the power button and the screen worked. My question is, should I be worried about this? I got the computer from a company I later found out is really difficult to deal with so I don't want to have to return or exchange it, but I also want to get my moneys worth.

My MacBook Pro which is only a year old was working fine, the only small problem was that it wouldn't play a video, so I restarted it but it never came back on. So I restarted it manually, the small light on the edge lit up, the screen with the apple came up along with the load bar, the empty load bar flashes a couple of times then the computer totally shuts off. Have turned starting in safe mode, same thing. Have tried starting holding down apple + option + R + P when turning on, same thing, have started starting up with the install disc in, same thing..

This started a week ago, When my early 2011 MacBook Pro8,2 (running Lion) is plugged in and I close the lid, the light on the side stays a solid bright white. When I open, my display turns on for about a second or two, but then turns off, causing me to have to unplug my laptop inorder to get the display back on.

My 2011 MacBook Pro screen broke so it is now half a laptop and the battery was also removed. Whenever I plug it in, the light on the front starts flashing and then it turns on. Sometimes it shuts off before the chime plays. I was using it today for about 30 minutes, and then the power button menu appears in the screen (sleep/shutdown/restart options menu) and then a few seconds later it shuts off completely without me touching it. After that I started it back up, and when it got to the desktop, and then it turned off without no warning at all (the power options didn't even show up).
I already tried resetting the SMC and PRAM/NVRAM and it seems like that didn't work.

I went to boot up my MacBook Pro and during the startup it turned itself off. Before I could try to turn it on again, it was rebooting itself and then instantly turned off. This now happens repeatedly, with the boot up sometimes reaching the grey loading screen and sometimes not, but it continuously shuts down and reboots until I hold down the power button for an extended period of time.
