MacBook Pro :: Computer Turns On For Half Second Then Shuts Off
Sep 3, 2010
Macbook pro intel core duo. My macbook is turned off, when I press the power button the light goes on and the computer starts making sounds of turning on for about half a second and than shuts off. I tried removing the battery and putting it again, I tried to hold the power button (the light flickers at one point and eventually shuts off as well after 2 seconds), and tried turning it on with the adapter plugged in and unplugged.
Starting abnormally, Like when I start my MacBook pro which is almost new. A bar runs on the white screen and then when it reached half way system shut down. Any way to reset my computer.Â
Also, when I am going to option, the system doesn't allow me by saying hard disk is locked.
Info: MacBook Pro (13-inch Mid 2010), OS X Mountain Lion (10.8.2)
My computer starts up with grey screen,apple logo, rotating cirlce, and then it shuts off. Is there anything i could do before i take it to the apple store for help?
where suddenly all apps scrollbars turns black and the mouse/keyboard hangs for a few second then they reappears and mouse/keyboard are working again. Here's a screenshot of what it looks like when scrollbars are going black: URL....At first it was doing it about 1 time every 5 minutes but now it has become literally unworkable as it hangs every 20-30 seconds.Â
I've a MDD G4 dual 1.0 along with the wide acrylic-bezel 20" Mac monitor with the light in the lower right corner. Yep, it's starting to look ancient. But I still have much use for it EXCEPT that it has a very nasty habit of turning itself off catastropically in mid-thought, as it were. Oddly, this behavior comes and goes in spurts. it will hit hard for a couple of weeks then a couple of months will pass with relative peace and stability. Then, back to the crisis.
Sometimes I get a warning from that power-on light in the bezel -- it might flash brighter for an instant, then within a few seconds the whole system loses power just as if I'd turned off my power strip. Other times, it pops in and out of sleep mode for several cycles, but usually this ends the same, with no power at all. Odder still, the machine has a tendency to turn itself on unaided. This can happen even after a controlled shutdown. It turns on, acts normal for 20 minutes, then maybe goes to sleep and wakes up a couple of times, then crashes. No intervention at all on my part at any time. This is not a software shutdown of any controlled variety. Anyone know what's happening? I can't tell you how much gnashing my teeth have endured.
My iBook G4 crashed on me one night, and the only way I could turn it on again was to unplug the power cord from my computer, turn it over, remove the battery, put the battery back in, plug the cord back into the computer, hold down the start button, and it would restart. Although, when it restarted, the fan would go on first, and then the computer would make the normal start sound. Some times the finder would be on the screen after I restarted it displaying a quick link icon of the hard drive. So after a few weeks, it did it again, then a few days, and then it got to the point where I had to keep my computer in the same position otherwise it might shut down.
Now, if the power cord is green everything is fine, but if I move my computer and bump the cord into the wrong place it turns from green to bright red, makes an evil buzzing sound, and in three seconds the computer shuts off and I have to restart by using the method above. If or when the power cord goes bright red I do have 3 seconds to pull out the cord before it shuts down. I then sleep the computer, put the cord back into the computer, and move the cord around until it is green again.
I took my computer to a mac genius, and when he looked at the crash report he said it was frequent, but not caused by the battery and couldn't tell me what was the exact problem. I bought a brand new power cord, but I still couldn't move the computer around to much or it would shut down.
1.) Has anyone ever heard of this happening? And if so, what causes it to be so touchy?
2.) What can I do to fix it myself?
3.) If I send it in, will they be able to fix it so that it is perfect again without having to spend more than the money assessed?
I would like to try to have it fixed. At this juncture, my only option is to send it in for $280 and hope they can fix the problem that no one seems to know what is the exact problem, or even where the problem stems from. I should add here that the battery is fully charged, and the report says it can hold about 1 hour of life, although it's more like 30 minutes, and then without warning to plug in or risk shutting down (like it used to give me) it will shut down.
Since a couple of days, my screen (iMac 27" mid 2011) turns off. Also, half of the screen looks darker. Is it a hardware problem or maybe can be solved by software?
I have a 2 year old aluminum (not uni-body) 15" Macbook Pro. Today when I turned on my computer, the front light went on, I heard the hard drive spin but the screeen remains completely black.
While unhooking my battery, I accidentally touched the metal contacts near the battery cable connector on my mid 2009 with a screw driver. My computer says 'battery not found' and only turns on while plugged in.  The computer doesn't detect a battery in the system profiler. Will buying a new battery resolve my issue?
MacBook Air randomly shuts down whether plugged in or on battery power but not when hooked up to a monitor and using bluetooth keyboard and mouse. Battery fully powered.
I was trying to install windows on my pro, and i had bootcamp chop the hard disk in half, but then my disk drive didnt read the cd so i had to download and install some file. and after i restarted i could no longer access the windows side, it just disappeared.....plus i cannot reset my hard disk, cant erase it, and i cant reinstall OS X because there is no memory left..
I have a MacBook Pro with the 9600gt in it. Since updating to 10.6.4 this morning 2 times while playing java games i've had the bottom half of my screen go black and most of the top half flicker. I've had to hold in the power button and reset both times. The second time I closed the screen and reopened it, the screen was black but no mouse and nothing moved.
Any advice? Would this be something to do with my graphics card or possibly some error in 10.6.4?Edit:: This is software related to 10.6.4 update and only happens when I open up a java game in a browser.
I am trying to fix a friends macbook pro. When I turn it on the screen shows the apple and the spiral underneath it spinning like it should then when it stalls for .2 seconds it goes to a white screen then there is vertical purple lines in groups across the screen. So the screen is white/purple. Then it fades to just white and I cant do anything.
I hooked up my monitor with a DVI cable to see if it was the motherboard that was possibly bad but the monitor works just fine with the cable. I can use the computer with the laptop keyboard/mouse and it works just fine. The laptop screen just stays blank the whole time. I uploaded a vid to utube for it. If anybody has any ideas for me please help. I dont know if this is a monitor problem or the inverter or the motherboard, possibly some other piece of hardware?

I've got a four year old Macbook Pro 17", running 10.5.8 OSC, 2.33 ghz, 3gb 667 mhz ddr2 sdram.
The power cord was unplugged, although the battery was fully charged. I plugged in my Canon printer for the first time in over a year. It printed half a document, then the computer shut down. I pushed the power button and got the start up chord, but then it shut down again. Tried this a few times. Then I unplugged the printer and plugged in the power chord. it started, but it's very slow, and I keep getting the pinwheel.
Recently my MBP retina late 2012 started crashing with the screen going all black leaving the keyboard lights on. I had to force it to restart. After a couple of attempts I could finally access the computer for about 10 min before it crashed again, during which i could see the logs. As of know it has been on for 1 hour without any issues but when I run some more hardware-intense programs it crashes. Since i bought the computer from a private person without insurance im not entitled to the 3 year warranty.Â
My MacBook Pro will not start. It chimes and the gray progress bar starts and then the computer shuts off. I am able to start it holding the Command +R keys and access Disk Utility. That is where it says my S.M.A.R.T. drive is "failing". I have a backup from Time Machine from a week ago. I am concerned the computer is going to die. What should I do and is my computer going to die?.

my monitor turn's off but the computer never goes into sleep mode. I've got both my monitor and computer set to turn off at 45 mintues of inactivity. I tried reseting the pram with no success. I deleted the com.apple.PowerManagement.plist file. but it still doesn't turn off, only the monitor. I've set it to 1 minute but only the monitor will turn off. Manually putting the computer to sleep work's fine.
I tried to install a larger hard drive in my mac mini pps version. Everything seems to be alright but after a few miniutes the computer gets hot on right side and then it shuts off .I have shut it down and wait untill I hear from you
At the beginning of last year I bought a 3.2GHz 27" iMac. About a month ago I noticed that, within about 5 minutes of starting my computer back up from sleep the left half of the screen would flick and become darker than the lower half (about 4 clicks of the light button lower). Sometimes the screen will flick to become even darker than this (but usually it returns to the 4 clicks darker after a short while), and sometimes it returns to normal only to go darker again.
While working on the computer, sometimes the screen will turn gray (from top to bottom) and a message will appear saying the computer must be restarted.So far the local Apple store has not been able to find the problem. The last solution the store tried was to replace the Airport Card, but that didn't work. Computer was purchased in December 2011.
I have a strange problem with my late-2008/early-2009 MBP. In the last couple of days, I have been using it and the screen goes black suddenly. It happened once for just a few seconds and then recovered, but today it completely shut off-- even though the battery was mostly charged (and I had received no warnings)-- so I had to reboot.
A few possibly relevant facts about this computer and this incident:
1) I've had it over a year and never had this problem before.
2) I had the logic board replaced recently because of an issue with sleep mode. This problem never appeared before the logic board was replaced (although this may be a coincidence).
3) Both times the problem happened this week, the computer was running on battery power.
4) Earlier this week (before the incident), I got a little warning to "Check battery" or something similar. The warning went away, though. Maybe this is a faulty battery issue?
5) When the computer completely shut off, it was also running a Time Machine backup. I noticed that TM has been having trouble today-- giving warnings about errors. Not sure if this could be related.
