Macbook shuts off on boot

macbook shuts off during boot after about 15 seconds. During boot at Apple logo, during a fsck process in safe mode, during a boot into Diskwarrior CD, even during a boot into Leopard install DVD. I am a decades mac user and have never had this problem. Tried zapping the pram, tried resetting system management controller (2 diff. ways). 10.5.8 was just installed, but i don't believe this was an issue. I believe it's hardware related. Any ideas?

Hi,
I am having problem with my macbook for like a month now. I is constantly shutting off when I start the pc or sometimes while I am using it. Would you know what the problem is. I tried to update software and it seems better for a bit, then it started again. Do you think the geek squad at Best buy would be able to fix it.
Thank you very much.

Snow Leopard (10.6.3) Installer Failed, MacBook Shuts off on boot

Hi all,
So a friend of mine recently bought an OOTB Snow Leopard install Disc from Apple and attempted to install OSX 10.6.3 on his MacBook White (I can't remember exactly what version of OSX he was running before but I know it was 10.5.x). Some time into the Installation, the Installer fails with the screen "Install Failed" and under that it says "Mac OSX could not be installed on your computer" with a big yellow exclamation sign. Under that it says " The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance. Click Restart to restart your computer and try installing again."
However, when he restarted and tried to boot up, the computer shuts off after getting to the grey Apple screen with rotating gear. I am not sure why the install failed, but I suspect now it has corrupted the old version of OSX which resided on the hard drive, and is causing the startup to fail. I had him boot from the OSX 10.6 Installation media and run Disk Utility and try to Repair his hard drive (Macintosh HD), but the Repair fails and window pops up "Disk Utility stopped repairing 'Macintosh HD'. Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed up files."
The details of the Repair printed the following:
Verify and Repair "Macintosh HD"
Checking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.
Invalid node structure
The volume Macintosh HD could not be verified completely.
Volume repair complete
Updating boot support partitions for the volume as required.
Error: Disk Utility can't repair this disk...disk, and restore your backed-up files.
I had him try to run repair a few times to be sure it would not complete, to which he said it failed the same each time. Then I had him try to boot up in Safe Mode, but the boot up was the same, computer powers off after hitting the Apple loading screen. He has confirmed that this could not be due to the battery or overheating. Is there anything else we can try before reformatting the drive? Is there a way to eliminate hard drive failure from the equation and conclude that it is a corrupt OS? I would hate for him to lose all of his data if there are any other options, please let me know.
Thanks,
Matt

Invalid node structure requires a robust disk repair utility such as DiskWarrior 4 - The Disk Utility for Mac Disk Repair, Mac Directory Repair
The pre installed Disk Utility app cannot repair this.

MacBook shuts off during start up...

When I turn on my computer it's starts to boot up normal but all I get is (and in this order) the Apple logo, a loading bar, and the spinning wheel. The bar only loads to about 5% then after about a minute my MacBook shuts off. I have two questions:
What could be wrong?
What is the shortcut the guys at the genius bar us to check the hardware status?

You can eject a stuck disc several ways, all during startup:
Hold down the eject key, or the space bar, or the mouse button until it pops out (sometimes it can feel like it isn't working, but be patient and try all three).
If none of those work, there are terminal commands we can try...

My macbook shuts off randomly, how do I know what's causing this and prevent it from happening again?

My macbook shuts off and I kept a journal for it because mine's got complications.
July 1, 2014 (Tuesday)
I spilled a cup of choclate milk on my keyboard, it was soaked! But my battery was drained so I know nothing had short out. So I turned it over and never tried to turn it on.
July 2
I went to the nearest apple center and asked them to clean it for me. (I knew it wasn't a good idea to clean it myself) They put it in a plastic bag but I asked them to open it as soon as possible so I know what parts are affected. They told me they'd take a picture of the inside for me and go back after an hour. Milk was still inside everywhere so I asked them to take it in.
July 8
I called to get an update on my mac and they said it wasn't economically practical to repair it because they recommended a full system replacement. I got depressed and accepted my Mac's fate. But what's annoying is I put my mac in on July 2 and they only tried to clean it in July 5 which makes me think that was the reason my mac was irreparable.
July 9
I took my mac and tried to find another opinion but I showed the diagnostics from the apple store and they said they couldn't fix it. My parents were getting ready to buy a new one.
July 13
I realized that my mac didn't have charge when milk spilled on it so I tried to charge it and BOOM IT OPENED. They keyboards were sticky and it takes a moment before my computer reacts to the trackpad but it works! Even all the keys works! But it doesn't charge.
After lunch, it was workingp perfectly and my batteries were at 30% charge! I was really happy!
(in the interval my mac works perfectly, it stays for normal 7 hours when battery is charged fully)
However at July 19
There was no electricity for four days (A typhoon came in the Philippines) and my battery is about 7% so I went to the public market to get it charge while I wait for electricity. I charged it for about 3 hours and sideways because it was inside my backpack while it charged so noone will notice it. When I got home and opened my laptop, it shut off randomly after my desktop appeared after start up. So I was sad.
July 20
I found a solution online to use the option-shift-power button my mac opened and worked normally!
July 21
My computer was normal in the morning then in the afternoon it shut off again after I waked it up from sleep. Tried option-shift for about 3-5 times before it worked with varying intervals from 5-20 minutes each
July 22
I get nervous when I use it but it worked perfectly I was even able to edit with Final-cut pro and HD clips.
Wednesday
Worked perfectly in the morning but in the afternoon, after waking it up from sleep it won't turn on tried the option-shift then I tried resetting the SMC for about three times (my mac is a unibody) but it didn't turn on the whole evening.
Today Thursday morning July 24
I tried to reset SMC first thing in the morning after the thing won't turn on. After about an hour, I tried to turn my mac on normally and it opened. So what I did is to back up all my files. (It took the whole afternoon) and at night I ran diagnostics (D during start up) and no threats were found
Haven't been experiencing the trouble, as of the moment I'm writing this Jul 25, Friday (12:13 AM) HK time Philippines.
So what I'm asking here is what do I do to make sure this doesn't occur anymore. I probably written a very detailed log. So what else (diagnostics and other) should I do to prevent this from happening again. School starts in August and I will need my laptop to work perfectly to let me go through college with less burden. Thank you and I hope you reply. Any more questions about details on my Mac will be answered

Get a new computer. Consider switching to regular milk, or even a light fruit juice.

My battery drains really fast and my macbook shuts off without warning when disconnected from power, what is wrong and how can I fix it?

My battery drains really fast and my macbook shuts off without warning basically everytime it is disconnected from power, what is wrong and how can I fix it? also whenever an application is opened the computer freezes and the application will either shut down or make the macbook run really loud.

MacBook shut off

It has happen three times in the past two days. My MacBook shut off randomly. I don't know what is wrong with it. I need help.

Make sure the battery is charged if you are using it without the adapter connected to an outlet.
Check System Preferences > Energy Saver > Schedule
If none of the above applies, try Resetting the System Management Controller (SMC)

My macbook shut off and wont turn back on. Im pretty sure it is charging. The LED light is on but only when the laptop is closed. Im in grad school and have lots saved. Please Help!

ronicr76,
First it would be helpful if you post the exact model, year and OS version you have.
> The LED light is on but only when the laptop is closed<
So that light is the sleep indicator and tells us that the laptop is going to sleep when you close the lid. That would be normal behavior so the machine is still working. Possibly you're experiencing a backlight failure. With the machine supposedly "on" use a flashlight to carefully examine the screen. Do you see the desktop? Yes? machine is still running and something is wrong with the backlight.
You should immediately backup your computer or at the very least pull vital files off. With the computer hooked to another Mac (The way this is done depends on the exact MacBook, E.g.FireWire 800 to FireWire 800.) Then you restart the computer and hold the "t" key down. This puts your MacBook into "target mode":
How to use and troubleshoot FireWire target disk mode
Once your files are off try an SMC reset:
Intel-based Macs: Resetting the System Management Controller (SMC)
Are you able to get the backlight back on by opening and closing the display? Yes? Broken backlight cable refer to qualified service place. Even if it doesn't come on and you can still see the desktop with a flashlight it is still probably the backlight. Could be the a backlight problem also.

Macbook shuts off. Hardware problem??

Hey guys,
I've got a MacBook Pro with Retina display for around 2 months now.
I was watching a movie today, and I was drinking a coke. When I put the glass of coke on my desk the MacBook shut off.
It was fully charged and it was still on the adapter.
I restarted it and if I just give a soft tap with my finger on the empty space on the right of the touchpad pad the MacBook shuts off.
I restarted it again and I gave a soft tap again on it and it fell off again. I left it there for an hour and went outside.
I just came back and after 5 minutes it shuts down again when it was just on the desk and nothing was around it.
Is it the battery that is a bit loose or what can it be?
I think I'll take it to the store this weekend, thats all I can do I guess or do you guys suggest something?
Thanks in adv,
Jesse

MacBook shuts off when power cord is disconnected

2007 White MacBook shuts off (not shutdown) when power cord is removed. Battery shows 98% charge. Any ideas? I plug AC power back in and it reboots when start button pushed. This problem just started tonight.
HELP!

Ronan... in your case, it looks like it's just time for a new battery. Your battery should hold a full charge for up to about 300 cycles. At that point, you should expect a decline in the charge capacity. As your battery has over 600 cycles, it sounds like it's had a good life. As you've had your MacBook for less than two years, it sounds like you are possibly using more cycles than necessary. You should try to use your MacBook while plugged in the majority of the time... but occasionally use it on battery (going through one or two cycles a week). A full cycle is a full charge and discharge. For example, if your battery is at 100% and you let it discharge to 90% and then you charge it back up to 100%, that is 1/10th of a cycle. You would need to do that 10 times to equal one cycle. If you started at 100% and let your battery discharge to 50% and then charged it up to full, that would be 1/2 cycle... doing this twice would equal one cycle. The number of cycles is the primary indicator of the life of your battery. It sounds like you are using your MacBook mostly on battery (with over 600 cycles in less than two years). After you replace your battery, try to run it plugged in for the majority of the time if possible. Many people are mistakenly under the impression that they should fully discharge their battery before charging it. This is not the case with Lithium Ion/Polymer batteries. This was the case with Nickel Cadmium or Nickel Metal Hydride batteries (much older rechargeable battery technologies). It seems many people still feel that the memory effect of the older battery technologies applies to newer battery technologies. Just the opposite is true.

Macbook shuts off and when I restart it the time is changed? Have I been Hacked?

macbook shuts off and when I restart it the time is changed? Have I been Hacked?
I am concerned that someone is going to steal my identiy and will in incurr 12 years of bad credit? I have just installed mountan lion and am unsure if this problem was caused by this? I suspect that if there was someone, or a program was trying to remotely access my computer then there would be traces of their actions.

How old is your macbook, and what condition is your battery in?
I doubt you're being hacked - more like your battery is dead.
Try doing both PRAM and SMC resets, setting the system time and seeing if they hold. Ensure you are connected to a power source.

MacBook shuts off during startup

I have a macbook I got in 08 that is running leopard. Ok so after running Onyx it told me that the volume needed to be repaired. I inserted the install disk and ran disk utility and the volume repair, but it told me it couldn't be fixed. So I quit out of all that and restarted my laptop, but now it won't get past the blue loading screen. The little wheel just goes and goes then my MacBook shuts off. I can still run the Mac os x installer. When i go again to disk utility I can see the Macintosh hd tab and before I couldn't. Is this a good sign?
Can anybody please help? Should i just try to do a restore, if it would let me or?? This is my first time dealing with a problem with a mac and I don't even know where to start.

Thanks for responding. Yes, I have used time machine, although I stopped it from backing up data about a year ago (big mistake). I was wondering if it would be best to restore with time machine or do a restore and then connect the external hd to get my data manually. Because have I changed my login name from the last backup and I don't know if that would cause any extra problems. I really don't want to lose anymore data.
I was also wondering how to go about using diskwarrior. Is it a separate disk? Because right now I don't know how I would get the install disk to eject from the laptop.

Macbook powers on than shuts off immediately booting from battery.

Hello guys and gals,
Ok my problem on my Core 2 duo 2.16ghz macbook pro is:
When i try to boot from my battery, it turns on for like 2 seconds than turns off.
Booting from my adapter, it runs just fine it charges the battery and everything. When its fully booted, and i go to uplug the magsafe connector the computer powers off immediately.
however i did find a semi-cure, with the macbook completely off running on battery only i hit and hold the power button until it gives a long beep than it will run fine. I can restart it to without a problem.
When i shut down, the problem occurs again. Please any help will be grand.

I actually have access to 2 macbook pros. I pretty much ruled out the battery by swapping them and they both work fine on the other one. The macbook is a 15"

Backlight shuts off when booted on Leopard Install DVD

Booting my macbook pro on the optical drive (by holding the "C" key at power up),with the Leopard install DVD causes the backlight on the display to shut off. Reboot with the OS on the hard disk (OS 10.4) and the display works fine. Playing with the screen brightness keys has no effect on the backlight when booted on the DVD. I also did a pmu reset (remove battery and hold the power button for 5 seconds) The display functions normally during regular use, It only happened when booted on the leopard install DVD. I was able to complete the install with a 2nd display connected to the dvi port and the display now works properly when booted under 10.5. Just wondering if anyone has seen this behavior or has an idea of the cause.

I have the same issue. Can some one please help? Thanks

MacBook Shuts off abruptly, bad battery?

I booted my MacBook up as usual and began to use it without any problems. I click on a link to watch a YouTube video and it plays for several seconds and then the computer shuts off right after that with no warning. I had over an our and a half of battery life left before this happened. After it shut down I checked the battery on the back and I pressed the button and only one light blinked very quickly. This has happened on more than one occasion and the only way to boot the computer back up is to plug it back in to the AC adapter. Once I check the battery life while it's charging, it will something insane like 170mAh.
Is it time to get a new battery? My MacBook is a late '06 model and I've had it since January of last year. I calibrate it once a month and I don't deplete it more than half of its charge life. Any ideas?
Thanks!

KBHenn...will you let us know what you find out if you contact AppleCare? I have the same problem it seems with the power outages. Mine goes out when I have 30-40% left it seems. The problem I'm seeing is that the calculator at the top of the screen is constantly changing and sometimes it's got crazy numbers like 200:00 hours left! It'll jump around all over the map. I also noticed the same thing as far as charging the charge says it'll take 28 minutes to fully charge and I come back in 10 minutes and it says 34 minutes to fully charge even though the % is going higher. Just weird.
I bought mine in Sept. '06. I'm not trying to hijack your thread here, but I'm curious as to how everyone's battery capacity is so high (mAh)? I've never checked mine until now and it's only 1267 Capacity. Do we simply have different batteries or is is this something that wears down over time? I'm in the same boat as you as having these issues, but once again since I'm over 300 cycles I'm curious to see if Apple Care will cover it. Good Luck!

Macbook shuts off when battery hits 30%

I have been using my Macbook Pro for two months without incident. However, over the last three days, the laptop dies when the battery hits 30%. It's very wierd. It always happens at exactly 30%, so it is reproducable. It doesn't go to sleep, or give a warning message, just shuts off. I have to plug it in to get it going.
If I keep it plugged in, there's no problem. I have reset the PRAM and PMU with no effect.
I'm pretty sure its a hardware problem. I have Win XP installed under Boot Camp, and the same thing happens in that OS. Is it a bad battery? Any advice would be appreciated.
Thanks

I am facing a similar problem. I have tried calibrating the battery and resetting the PMU to no avail. The interesting thing is that when I calibrate and charge the battery, the maximum battery time available is 35 minutes. A month ago it was 3:40. In addition, some times I get a message when I am 50% that I should plugin the laptop immediately, and then the battery keeps working 'normally'.
I think I will need to get a new battery from apple.
