Macbook shuts down after apple logo...

I bought a Macbook a few weeks ago without the original cd. It has OS X 10.5.8 installed. Everything worked fine until it decided to just shut off a few seconds after pressing the power button. On pressing the power button, I get the start up chime, a grey screen, the Apple logo, and as soon as the round timer shows up under the apple, it shuts off.
It will boot in safe mode just fine, but in Verbose mode, I really can't make out the last thread because as soon as it shows it, it shuts down.
I was able to see "Previous forced shutdown cause -128" and "appletymcedriver probe fails"
Any ideas on how to find and update corrupt files without having to resort to re-install everything? Remember, I don't have the original cd. Thanks...

I thought i fixed the problem by reinstalling the 10.5.8 combo update. It started again without problems right after that. But about an hour later, it shut off by itself right after I rebooted...
Well, I went ahead and bought snow leopard and am in the process of installing it now. I just went the route Apple wants you to take. No fancy hd wiping or anything, just stick the cd in and follow directions. Right in the middle of the installation it shut off, then, it tried to start again and shut off one more time. After waiting about 5 minutes, I restarted in safe mode, it recovered the installation and went on. It says I got 13 minutes to wait so Ill update shortly. Weird, but true...

IMac shut downs after Apple logo appears!

Since I installed Maverick my iMac been acting weird. Now when I turn it on it shuts down after the Apple logo appears!
I've looked for similar problems but I've other issue here, I've a login security username\password. So, I can't pick the hard driver and repair it simpley!
Any help...

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
     after the chime press and hold down the OPTION key until the boot manager screen appears.
     Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
     Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).

MacBook Pro does not start up. Shuts down after apple logo screen with a loading bar.

I booted my macbook pro up today and i noticed it took a while to do so. i also noticed that the fans were going fast and the macbook was getting hot during the start up process. When i went to the screen i also noticed a loading bar which i havent noticed before when starting up the mac. Once the loading bar has reached the end, the macbook just turns off and the same thing happens over and over. I am on mountain lion

I went to apple today and they told me that the hard drive has unmounted itself. They have my macbook right now and they said they're going to replace the wire that connects the hard drive to the logic board and see if this solves the issue. If it doesn't work they will replace the existing 250GB hard drive in my macbook with a 500GB as they no longer make that size hard drives (cost of £130 for the replacement). The problem is that i dont have my macbook backed up so will there be anyway to get data off the od hard drive?

Macbook shuts down after grey screen

My MacBook shuts down after the gray screen every time I try to start it it does not work

While we all have MacBooks in this forum most of us don’t run Mountain Lion. There's a Mountain Lion Support Community where everybody has Mountain Lion. You should also post this question there to increase your chances of getting an answer. https://discussions.apple.com/community/mac_os/os_x_mountain_lion
You should also ask this in the MacBook Pro forum. This is the forum for the white and black plastic MacBooks that were discontinued in 2010.

My macbook shuts down after 5 minutes

My macbook shuts down after 5 - 10 minutes, and I have to restart it each time. Can anyone help me with this? I've tried resetting the PRAM, re-instatlling the OS, switching HDD's. I asked a friend of mine what it could be and he said it may possibly be the power switch button. Any answers out there?

Have you tried resetting the System Management Controller? That is a good first step for power related issues such as this.
If that doesn't do it, you are looking at a hardware repair.
Best of luck.

MacBook Shuts Down After Unplugging Powercord Although Battery is Installed

Hi,
Whenever I disconnect the power cord of my MacBook, the OS shuts down within 2-5 seconds. The battery is installed and it has a 80% health and it has 185 charge cycles. I've been experiencing this strange behavior after two days of installing (Secrets Preference Pane). But I'm not sure if it was behind the problem. I even uninstalled Secrets preference pane but the problem still exist.
At first I though the battery is dead, but for some reason I tried running the laptop later on the battery power and it ran for whole 2+ hours until it was fully discharged. I then charged the battery fully and used it again and it was working like a charm. But later the problem returned and the MacBook shuts down whenever it is not connected to the power cord. If the battery was dead, then how come it runs without a problem sometimes? also the health indicator shows that the battery is 80% healthy and the charging cycles is not much and whenever the system shuts down, the indicator on the bottom of the battery shows that it is fully charged.
I don't know what is causing the problem, and why sometimes the problem arises and sometimes it goes away.
I am using a 2007 white MacBook with the original battery (provided with the laptop). I am running Mac OS 10.6.2.
I tried several solutions such as:
- Cleaning the battery and MacBook ports.
- Resetting the PRAM.
- Fully discharging the battery and then fully charging it.
But it seems that I am not able to resolve the problem. I would appreciate any provided help.
Thanks,
shaknon
Note: Here are two pictures that shows stats about the battery:
1- http://jump.fm/SAOBW
2- http://jump.fm/JBHYI

I am having identical issues as you described - although I haven't installed secrets preference pane (so I doubt that's involved).
My problem went on for hours one night, I got sick of dealing with it and went to sleep with AC adapter unplugged and macbook off. The next day, it worked fine all day long. Now here I am in the evening - had a power cut, AC adapter went off obviously, and MacBook powered off. Again now I have this problem.
I tried everything you've talked about (PRAM reset) as well as SMC reset, no change. My battery stats look great, says battery is healthy. This started happening to me a few days ago, I upgraded to 10.6 a few weeks ago.. not sure what caused this to start happening.
I found one VERY interesting thing, maybe you can check this: when I have the problem, with AC adapter unhooked, when I try to power up my MacBook it comes up for 2-5 seconds (sometimes until the apple tone, sometimes not), and turns off. If I HOLD THE POWER BUTTON for 5+ seconds the MacBook remains on, the white light on the front flashes, and I get a long tone. This procedure is supposed to be used for firmware updates or something. Anyway, when I do this, the computer comes up perfectly and it uses the battery. When I hook an AC adapter up, that works, but as soon as I unplug it I am back to the same problem. You should try this and see if it works for you, it may be a clue. If nothing else, it's a good way to still use your laptop if you are on the go and can't be dead in the water
My wife has a MacBook slightly newer than mine, I'm going to try her battery when possible to see if that solves the problem. I hesitate to go to the genius bar as they are terrible where I live and it's always been a waste of time
(Also, the battery update fails for me as well).

MacBook shuts down after 2s of sleep

I've run out of ideas of how to fix a problem that started on the weekend.
It's an early 2009 2GHz MacBook running 10.6.7 with 5GB of ram.
The problem is that the laptop shuts down about 2 seconds after it goes to sleep.
Initially it was also shutting down after a minute of being left idle but that behaviour has stopped since I repaired the hard disk last night. It does however now beep (even if muted) and display the shutdown dialogue box after being left idle for a couple of minutes (it continues to give a prompt beep every couple of minutes, again even if muted).
Once shut down it won't respond to the power button unless I have disconnected both the power charger and battery for a few seconds. It will then restart from either the battery or power charger.
The shut down problem is the same with or without the battery onboard. Battery count is 163 and condition is reported as "normal" in Profiler.
I've tried starting from a fresh OS X install of both 10.6 and 10.5.6 on a USB drive but it still shuts down on sleep.
I've reset SMC, repaired permissions, repaired the disc (there were some errors that were repaired) and now run out of things to try.
The system.log shows the following when it shutdowns down while sleeping:
May 30 20:50:52 loginwindow[41]: loginwindow SleepWakeCallback WILL sleep
May 30 20:50:54 configd[14]: PMConnection mDNSResponder com.apple.powermanagement.applicationresponse.slowresponse 2047 ms
Any ideas?

If I recall correctly, MacBooks go into a mode of sleep called Hibernate by default. In this mode, the contents of the memory are saved to disk when the sleep starts. You can tell if this is happening by looking at the light on the front. If it stays fully on for 10 seconds or so then the computer is hibernating, otherwise it is just asleep.
Anyway, to stop rambling - maybe you should try toggling between normal sleep and hibernate to see if that makes any difference. Follow the instructions on this page:

Macbook shutting down after 10 seconds of inactivity

Hi,
My daughters macbook will not power up unless you run your finger over the trackpad, it just shuts down if you are not doing this. This also happens during normal use if left for more than 10 seconds. It puts the the shut down message and powers down the macbook. Any ideas?

Are you still having problems? or is it fixed?
I have just been through a big problem similar to this but mine was shutting down after 40mins.
The reason I said "big" was that I have had the problem when doing large downloads and then having to restart them again only to have it happen again. I had spoken to AppleCare and for more than a year the issue was not resolved.
I was told to take my computer the local 'MacDoctors' and they said they thought it was the Hard Drive and replaced it and then charged me to transfer my data. The data transfer was mucked up (if you don't know what Mucked Up means replace the 'M' with a 'F' and you'll get it) causing more trouble.
It didn't fix the problem but it did mean I couldn't go for a Macca's for a month (kidding - I still went to Maccas but didn't order fries).
Anyway, finally, in desperation and much frustration I thought I would give the Apple Care guys another go and got an 'escalation' guy that really took charge of the problem. He didn't know what to do to fix it but was talking about it to one of his fellow super techosleuths and his friend asked has he looked at the 'Security and Privacy' option in the System Preferences?
Inside that option is an 'Advance' option (OSX 10.7.5) and once opened has a tick box which asks when you want your computer to shut down. Sure enough it was ticked for 40mins - it is now unticked.
I have mentioned this to Applecare people and the MacDoctors and NONE of them had any idea that this tick box was in that section of the system.

My MacBook air shuts down when Apple logo appears

Hey. My MacBook started to run slow and I forced a shut down and now when I try to start the mac, everytime it shuts down when the apple logo appears.
What can I do and i also haven't backed up any of my files and I really need that stuff.

If you really do have a Mid 2013 Mac Air model then it is still in warranty, as the standard Apple warranty is one year from date of purchase. So take it into an Apple store and have it diagnosed and fixed under the warranty. There is some type of hardware problem that only Apple can fix.

Mac OS Mountain Lion Shuts down at Apple logo with a progress bar appearing under it.

Last Night there were two updates available which i downloaded and after that it asked for a restart, when i restarted the Mac, it gave me a progress bar for the updates at the middle of which it said, Installation of Updates can not be Completed and My mac book froze. After that i Shutdown my Macbook Pro by holding the Shutdown button for a little while.
When i restarted the Macbook Pro, it gave remained at apple logo for a while then a progress bar appeared after which it shut down itself and it is doing the same since then.
I have got windows over Boot Camp in my Macbook Pro and i can boot into Windows which is running fine and i can access all the data on my Main Partition through Windows as well but i am unable to boot into Mac os Mountain Lion.
I have tried Repairing the Partition by going into Recovey and it Fails, I have tried Resetting the PRAM and that hasn't worked either, i have tried re-installing the Mac os Mountain Lion from Recovery but that says that all my Partitions are Locked.
I haven't got any backup of my data through Time Machine so i was thinking as i can boot into Windows and access the data and as all this is because of the Installation of Updates Failure so there should be some way to manually edit the Boot Files to trick the Mac book into thinking that there weren't any updates or to simply clear the data from Updates.
Can anyone please help me if you have any better suggestions.

If it's still under warranty or with AppleCare (even if it isn't, really) take it in to an Apple store. If you can get at your personal files from Windows, copy them to an external drive first. That includes anything you have in Windows that you need to keep. Sounds like the drive is going south and if it has to be replaced, you'll lose everything if you don't have it backed up.

MacBook shuts down after low battery warning

Hi,
up until recently my macbook's battery has been working just fine. but then lately i noticed that a few minutes after it displays the low battery warning it shuts down by itself.
before, when the low battery warning would display i could still continue working on my macbook for several minutes until it goes to sleep -- only then would i connect it to the power cord.
unlike the other posts (concerning batteries) that i've read, i have no problems turning my macbook on/off before or after this event has occured. neither does it shut itself down when the battery is halfway. my problem really only happens after the low battery warning has been displayed.
i wanted to calibrate my battery but then that would require my macbook to go to sleep once it reaches a battery level of less than 5%-10% -- mine just shuts down completely.
is this shutting down thing a substitution mechanism to save the laptop's memory -- instead of going to sleep, it'd just shut down?? how can i fix this?
thanks in advance for the help.
MacBook Mac OS X (10.4.8) 512MB, 2GHz Intel Core Duo

For what it is worth, I now have the same issue. Only I don't even see the low battery warning, it gets to 15% or 10% and bang, no power. This is not good, by the way and is bound to corrupt something in the system as OSX requires some house keeping when you shut down the computer properly. This instant off is not a proper shut down. I took my MacBook in and they wouldnt simply replace the battery, they want to keep the computer and give it back to me in a few days. I rely on this puter for work 5 days a week, so I was trying to avoid this.
Oh well I guess a trip to the Apple store is unavoidable.

MacBook shuts down after update on startup

Today my MacBook has been acting up again. This time, I shut it Down and restarted it, then it started applying the update for a while. Then, after it's done, it shus down. When I power it up again, it updates again. Then the same cycle repeats and repeats. Could someone please help me?

When I turn on my macbook on and leave it alone for about one minute a pop up shows saying are you sure you want to turn off you computer with the options to turn off, restard, sleep and canceled and if you don't cancel it quickly it just turn off the computer. It is the same dialogue that show when you have schedule the computer to turn off in the preference pane. I already try deleting the plist of the power settings this happened with or without the power cord, with any combination of setting in power pane and with or without any schedule in the same pane. Any idea how to fix this? is very annoying
