No Warning shut down / No boot / No MagSafe LED

Hi,
I was browsing and listening to music on battery when, without warning, the music turned off and a few seconds later my MBP turned itself off.
Now, it won't start up anymore!
Symptoms:
No MagSafe led on (no green / no red / no color at all)
No noise of HDD or Combo drive at all
No visual sign at all
Looks pretty much like a clinical death!
Tried to remove battery and press start button for up to 10s, but it did not work.
Any idea on what might bring my MBP back to life?
Thanks for your support.
Tim

If you've had it for a year and have never calibrated your battery... there is a good chance this may be your problem. Basically, calibrating your battery completely discharges your battery and recharges it again. What this does is allows your MacBook to "know" how much time is remaining for a fully charged battery. Think about it this way... If you took a paper cup and stuck a pin in the bottom and timed how long it took for all the water to drain out, you would know how long it would take for the water to drain if you filled up the cup the next time. That's sort of what calibrating the battery does. If you don't calibrate the battery, over time, your MacBook loses track of how full or empty the battery may be and that makes it impossible for it to accurately "guess" how much time you may have left. As a result, it may think you have 40 minutes left when the battery is actually nearly depleted. Since the MacBook may think it has more time than it does, it doesn't know to shut down gracefully. In effect, the battery actually dies before the MacBook knows that the charge has gotten that low. You should calibrate your battery at least every other month or so.
This may not resolve your problem, but it's a good place to start.

HP Pavilion a1730n shuts down during boot

Have been using the Desktop Pavilion a1730n for several months after upgrading to Windows 7 Pro 64 bit. Without any warning signs, now the CPU shuts down during boot up. When I shut the main power supply switch off and then turn it back on, then switch the CPU on with the front on/off button it gets 15-20 seconds into the bootup and then powers off spontaneously and completely.
If I try to start it immediately again without turning the main power supply switch off then on and only depress the front on/off switch, it starts to boot but only gets about 10 seconds (varies) in to the boot process before in shuts down.
What could this be? the power supply? the mother board?
ANY ideas would be appreciated.

Hi , Sounds like the power supply , when a load is put on the supply it does not seem to be able to cope with the correct output . You can buy a new supply ( same watt output or better )eg; if you have a 400watt supply get 400watt or higher supply as replacment . Checkurtech

Mac shuts down after boot. Is it the logic board?

mac shuts down after boot. Doesn't go beyond gray screen with apple. Is it the logic board?
I do not have the start up disks to safe boot or check the hardware.
Any ideas what the problem is or is it junk? It is 8 years old.

Shutdown your machine. Hold down the shift key. Poweron. Wait awhile Wait awhile while you harddrive

I'd let the machine sit for awhile in open firmware & see if it stays alive. Do a few prints.
Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime. Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:
reset-nvram
set-defaults
reset-all
"The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."

N200 shuts down during boot

Dear Lenovo,
I have a problem with my N200 laptop. Notebook shuts down during boot. Sometimes it is immediately after "Lenovo screen", sometimes it is when Vista logo appears. I found out that this is always when notebook is "cold". It does't matter if I want to switch on my notebook or if I want to restore it from hibernation or sleep mode. Next thing is that it always crashes when fan starts work at full tilt (I checked the fan but it is clear). When notebook starts correctly then it works without problems. Usually I have to switch it on about three times then it is OK. This problem takes about 2 weeks. I have my laptop about 7 month. Do you have any ideas how to solve this problem?
And another thing - I forget to send registration card to Lenovo and now I am afraid that I will be without warranty. Can I send it still now?
Thank you for answer and sorry for my English.
Gabi

Yes, problem with the video card sounds plausible! Any not so successful updates recently? It is sometimes to make a good uninstall, which is required to make a good install.
4in1 drivers should - esp. with W98 and ME - be installed while in SafeMode and with all autostarting programs disabled, for example Antivirus and utilities.
Else, since you have a damaged regedit, I would reinstall Windows. You might have done something for example an upgrade or new install the registry, not healthy, has made a note of. Some utilities also overwrite and change system files without good results.

I can only start my iBookG4 after deleting preferences. I have to go into single user mode to do so. If I don't go into single user mode, the computer shuts down during boot up. What might be the problem?

I do not have a startup disk. I did try fsck (based on what I learned from your reply-thank you). This failed (fsck); here is the message:
** Checking catalog file.
Invalid key length

** Volume check failed.
/dev/rdisk03 (hfs) EXITED WITH SIGNAL 8.
I am sure this is an easy fix; I just have no clue how.

MacBook Air shuts down during boot

My Macbook Air (OS X Yosemite - Early 2014) automatically shuts down during boot, with the screen flashes during the loading bar at 40% and then shuts down. I've tried to reboot many times but it wouldn't get past the 40% on the loading bar.
I've also tried the following but none worked:
The Apple Hardware Test shows that "There may be an issue with a memory module." (PPM002, PPM003, PPM004) - though I've checked that the reference code and the definition doesn't match, as "There may be an issue with a memory module." should be PPM001, and PPM002-PPM015 should be "There may be an issue with the onboard memory.". I've sent this message to Apple and they'd only provided the option to visit their retail store.
Also, the Recovery Mode isn't much help either. As do not have a backup of my HD, I'm not able to restore from Time Machine Backup.
So, I've tried to reinstall OS X Yosemite, but it says "Unavailable to install OS X". A website online says that you can resolve this issue by correcting the date through terminal, but the basic menu bar won't appear, in which I'm not able to access Terminal during the Recovery Mode.
Therefore, I've also tried the Disk Utility, which it shows it can't be repaired, with the following messages: Invalid Node Structure (4, 57963), and 2 messages regarding the Invalid Extent Entry (4, 47013) and (4, 40808). The Single User Mode with the command fsck -fy yields the same message.
Is there any other options then to visit the Apple Retail Store?

Invalid node structure
I'm pretty sure you need more then Disk Utility to repair the drive.

Assuming you have Snow Leopard installed, you can try reinstalling the Mac OS but you'll have to do this from another Mac.

Mac shuts down when booting Recovery HD or holding down Command R

Ok, so I had Windows 7 installed on my MacBook Pro. I decided I wanted to get rid of it because I no longer needed it. I started to remove it via the Boot Camp Assistant when suddenly, my computer froze halfway through its' progress. I held down the power button and restarted my computer. I went to check back and Windows was gone. It only gave me the option to install Windows 7 instead of "Remove Partition". A few days later, I decided that I wanted to restore my mac to it's factory settings however, every time I held down Command+R or booted Recovery HD via the option key, the screen would go grey with the apple logo followed by the spinning icon underneath. After awhile, it would shut down. I boot it up again and it will only boot to the desktop. What should I do? Bootcamp assistant won't even open either. The icon flashes and then it disappears.

Just got this responce dont know if it works, havent tried yet

Re: Mac recovery doesnt work in response to Phatwo
Boot OS X Internet Recovery:
using three fingers press and hold the following keys: ⌘ (command), option, and R.
With a fourth finger press the power button to turn on the Mac.
Keep the other three fingers where they are until you see the "spinning globe" icon.
Your 2011 MBP will have required a firmware update to enable this option. It was released years ago so it's very likely you complied with it.
If your HD is damaged, it will require replacement. The effects of "repairing" it using Disk Utility will be temporary, at best.

Shut down and booting-up takes longer than usual on iMac 27".

Hi there,
I have a problem with my 27" iMac (model listed somewhere), it appears to take an extraordinarily long time to boot up and shut down compared to a few weeks (or even days) ago.
At the moment, at shut-down, it hangs on the blue screen with a spinning wheel for quite a long time, which never used to happen.
At boot-up, it takes quite a bit more time to boot-up.
For comparison, it took about 10-20 seconds to boot-up previously, but now it is taking about 50-60 seconds.
All of this has happened randomly, and I have no idea what the cause is.
I bought my iMac on Black Friday 2010 from the online store.
Thanks,
Jack

Non-shutting down might indicate that the Mac is waiting for something to finish before it can complete the process, and whatever that is isn't doing so. Launch Console in Utilities and check the system logs to see what the last thing running was and perhaps that might give you a clue.

Why did Mountain Lion slow down my shut down and boot up time for my MacBook Pro?

I had Snow Leopard, and not Lion. My shut down time rose from about 5 seconds to 10-15 seconds. My start up time also increased noticeabley. Any reason why because I thought Mountain Lion was supposed to be faster.

I have very few apps other than what came on my MBP. I've checked most other, really dont think this is the problem. My MBP is not junked/cluttered up. Not many programs, just pictures, videos, and some docs. Everything seems to work smoothly once on, but the start up and shut down times are still double what they were when I bought with snow leopard (Not Windows like, but scary close). I cannot find any solution that will work. My opinion, should not have to do a clean install for it to work. Some folks have not experienced these issues, so I think its some setting or something else that is my problem. I have 4GB RAM, and considering increasing to 8, but from what I have read else where thsi will not increase boot or shutdown, way even increase. Right now, not sure if the new ML features out way the slow boot and shut down.

Macbook Pro screen is black and will not shut down or boot up right.

Last night my 2007 macbook pro would not go to sleep properly. When I closed the book the light stayed on and the fan continued running. Later I shut it down.
This morning the computer turned on but the screen is black. I tried closing the book but again it would not sleep. I hold down the power button and it seems to shut down but when I push the power button again the light comes back on and the fan starts up but the screen stays black and there is no powerup sound.
The lights on the battery are lit up. I tried taking the battery out but same thing.
Any help is greatly appreciated.

Try:
Intel-based Macs: Resetting the System Management Controller (SMC)
Resetting your Mac's PRAM and NVRAM
Then see if it will boot into Safe Mode. Do not remove the battery unless it's defective.
If none of the above work then you may have a hardware failure so take it in for service.

Computer sometimes shuts down during boot, help please.

Hey guys,
My specs:
2500K @ 4.5 GHz 1.37V (12 Hours P95 stable + 10 IBT passes)
MSI Z77A-GD65
8GB DDR3-1600 Corsair Vengeance (2x4GB)
EVGA GTX680 Superclocked
Crucial M4 SSD 128GB
WD 1TB Caviar Blue
Seasonic X-650 PSU
The PC is roughly 1 year old and I built it.
Problem is, and this has been ongoing since I built it, sometimes, when I turn on the PC, it will start booting and then power itself off, after that it turns itself back on and Windows 7 loads, exactly what happens when you apple new OC settings for example.
There is never more than 1 shutdown when this happens and it never happens when the PC is on and working, just during boot.
I ruled out heating issues, everything is well ventilated in my Corsair 650D case, all fans are working and the CPU temps are good (Using Zalman CNPS10X cooler)
I think we can also rule out any PSU issues since I recently tested my PC with P95 again after updating my BIOS for more than 12 hours and it was rock solid. I've also never had a shutdown during gaming since I got the PC.
My Overclock is raw, I have disabled, EuP 2013, C1E, EIST, Overspeed Protection, Intel C-State.
Is there any BIOS setting which could be causing this? I noticed that there's a setting under EuP 2013 called "Restore after AC Power Loss" and you can choose Power Off/Power On/Last State. But I think it only related to occasions where the PC gets shut down due to a power outage?
I am inclined to think that this issue is more related to a MB BIOS setting than to the PSU since I never had any stability issues with the PC during OC testing or when gaming.
Which leaves me with the Power outlet. I am using an outlet splitter and currently there are 7 products connected to 1 socket:
1. PC
2. Yamaha RXV-471 Receiver
3. Morel Sub-8 Subwoofer
4. PS3 (Off 99% of the time)
5. Internet Modem/Router
6. TV Box
7. 42" LED TV Screen
The only thing I can think of is that maybe when booting up, not enough power is provided to the PSU and it turns off?
I have 1 other clear outlet next to the one being used and I'm fairly certain they both go to the same place in the panel because they are adjacent.
I can also try to replace the power cord, however, I replaced it once and I do recall it was happening prior to replacing the cord several months ago.
Any suggestions? Thanks

That's normal, the memory you have is 1333 with an overclock profile of 1600. (XMP) The double cold boot has been an issue for ages on the z77a-gd65 although I thought it was corrected by the latest bios's.
Oh so true. When it is really cold in the morning, not always, at first start of the machine, I will get a double boot behavior on a Z68 G3. No big deal, as xmad stated, this double boot behavior has been a trait of Intel for a long time. Usually disable of EuP 2013 cures it, but the OC and particular frequency combinations play a part in it, and mysteriously, cold mornings once in awhile.

MacBook shuts down unexpectedly when the MagSafe is touched or removed

Hi, I got my new MacBook during November of 2009 but two weeks ago it started shutting down by itself once I touch the magsafe of the macbook or remove the magsafe. All it needs is a simple touch and it shuts down. When it does shut down, the light indicator doesn't come on anymore. I have to keep removing the magsafe, and plugging it back in like 20 times until it starts charging again. So now I just let it fully charge every time I use it since any sudden movement will cause it to shut down. I will be making an appointment next week at the apple store because I had no time to go these past 2 weeks. I never dropped it and take good care of it. I am just wondering what might be the cause of this? I hope they do not take weeks to fix the mac since I have a lot of homework to do... Thanks!

Anything is possible, but a firmware issue is not very probable.
Did Apple troubleshoot and repair your Mac? It's not the iBook as listed in your profile is it?
If Apple recently did the repairs and the problem persist then you should contact them, as they are obligated to fix it.
Did they for sure rule out the Magsafe adapter?
Which board did they replace? The logic board or just the DC board? Or both?

MBP shuts down after booting from a disc

How is everyone doing? I hope okay with their macs!
Well, if I boot from my MacBook Pro Install discs, the computer boots off of the discs.
But if I try booting off any media that I burned, the computer shuts down automatically.
What I do:
Put in the disc (I tried both DiskWarrior and Drive Genius 2),
hold down the C key,
the apple logo displays,
the discs starts to spin louder (like if it were to start reading it),
then the computer restarts after showing the spinning wheel for about half a second.
I thought that maybe it had to do with me adding a firmware password as requested by Orbicule's Undercover... so I removed the firmware password and I still got the same results.
Does anyone know why this is happening [to me]?
Any replies or comments are thanked in advance.

I found out why... its because I have the new macbook pro with the penryn processor.
Penryn processor's fault.
End of story.

Lenovo3000 N100 shuts down after boot

I have Lenovo300 N100. Have been using it for 6 years. Now it has a problem. It shuts down automatically after boot. It stays on for about a minute or two and then powers off automatically. One strange thing is, If I start it after a long delay (4-5 days) it boots and stays on for a longer time (15-20 min) before auto power off. But more I use it, quicker it powers off. Any help. Avinash

Hi Avidesh
Welcome to the community
Since your system is powering on after few minutes after it is powered on . It seems to me that the Heat Sink Fan might have accumulated some dust and it is not able to properly cool down the system , that is the reason the system is powering Off after so me time . I would recommend to have the heatsink fan cleaned properly
You may Please refer to HMM user manual how to open the heatsink fan and then can clean same .

Macbook shuts down when booting

Dear friends I have lot's of problems with my Macbook late 2009 when trying to boot.
Few days ago I tried to verify my disc in Disc Utility and I had this message log:
Invalid node structure
The volume Macintosh HD needs to be repaired
Error: The underlying task reported failure on exit
As soon as I did this my Macbook freezed and I couldn't do anything except trying to rebooting it.
From that moment when I try to reboot I have this kind of problem here: http://support.apple.com/kb/TS3148?viewlocale=en_US
but when it tries to load my Macbook shuts down by it self.
I tried to repair the disk booting from the MacOS disk and then used utility disc to repair it but an error message appeared saying that it was impossibile.
I don't know what to do, I need to get my files back because I don't have back ups. What can I do?
Please help me.

not much.
if disk utility can not repair the disk, one option is to completely erase and install. but your hard drive may be physically damaged in which case you've to get a new one. thinking of a backup after the worst case scenario happened is regretfully a bit late.
i can think of various ways for trying to retrieve your data from the disk, but for that you'll need another hdd drive and an external usb casing.
first way is to clone a bootable system from another mac to an external usb drive, start up your book from that external drive and then try to access it's internal drive via finder or third party data retrieval software. then reformating the internal disk and doing a fresh install, hoping that the damage was not physical.
second way is to install a new HDD in the book, install os x and then putting the old one into an external usb casing, so that you can later try to access it from the fresh installed book.
