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.

Macbook Pro shuts down during boot

Hi there,
Few days ago I spilled some beer on my 2 weeks old Macbook Pro... I immediately cleaned it, removed the battery and charger and left it to dry for 1.5 day.
After the drying period I tried to power up the machine, it did work but unfortutanely shut itself during the boot (the spinning wheel) and power button didn't respond again until I removed and re-connect my battery. Tried everything such as Nvram/Pram and SMC reset, single user thing, verbose mode, changing ram dimms but got nothing. It did eventually boot with hardware test but again got nothing as the test indicated that there weren't any problems.
It always shuts itself after "Checking catalog file" in the verbose mode.
(The machine shuts itself even when I try to boot it with os x installation disc so the only thing that I can reach is the hardware test.)
(To tell the truth I don't know if I succeeded creating a bootable installation disc as I did it under windows.. I'm hoping that I failed and that it can actually boot from dvd drive)
Did I just screwed my logic-board, if so how can I run all the tests.. Any suggestions?

Immediately disconnect all peripherals, power cord & remove the battery. Turn the computer over with the lid partly open and the hinge facing upward to let the liquid drain. Do not flop it over and lay it flat - you want to separate it from the moisture. Place paper or cloth towels under the machine to sop up the mess.
After the computer disgorges whatever you spilled on it, don't turn it on for 72 hours or longer. You want to computer to dry out completely before turning it on again.
Some users here swear by hairdryers. Blow drying the innards may bake whatever was in the liquid onto delicate computer components. Better to let the computer air dry.
Use plain tepid water to clean out the computer. If you spilled iced beverage more than likely this ice fried the hot motherboard.
Sugary, acidic or milky drinks will almost always cause problems later on as the residue starts slowly corroding the computer innards.
Swab down any sticky parts with distilled water or denatured alcohol.
If none of the above works, you will need to take the computer to a repair shop. Apple Care does not cover liquid or food damage. Believe me, they can tell. So the old "my computer stopped working" line is not going to work.
In order to not void your warranty any further, take it and let the staff clean it. It's worth it for a 2 week old computer. In the future, avoid eating and drinking while using your computer. Will avoid future heartache and expense.

My MacBook Air shuts down when its more than half way charged and won't turn on unless I plug it in to the adapter? Why is this happening and how can I fix it?

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.

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.

Macbook Pro Shuts Down During or Soon After Start-Up

My macbook pro shuts down after booting up. Sometimes it makes it to the desktop, but sometimes just to the gray screen. Also, at desktop, it asks if I want to shut down. Is something pressing on the shutdown button? Any help on what to do?

Try resetting the SMC.

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
(4, 8198)
** Volume check failed.
/dev/rdisk03 (hfs) EXITED WITH SIGNAL 8.
I am sure this is an easy fix; I just have no clue how.

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

My MacBook Air shut down is slower than other macs I have seen

I think this is due to the recent Mac OS 10.8.2 update
My MacBook Air shuts down slower than usual. It will get slow and show a white screen with a spinining wheel taking up to 15 seconds.
This is longer than the startup time.
When it was new, I think it was running Mac OS 10.8.1. Shutdown was super speedy and took maybe just 3 seconds. It then asked me to update, so I obviously did, since I thought new improvments were made.
So how can I get rid of this slow shut down timings?

You might try resetting the SMC. If that does not work, take it in for service (you are under warranty).

MacBook Air shuts down unexpectedly

MacBook Air (2012) keeps shutting down unexpectedly. And then shuts down during start up several times before it works again.
I was getting an "Error: shrinkdb" message in console for a while.
I tried reinstalling Yosemite which did nothing. I also tried downgrading to Mavericks which also did nothing.
I've verified/repaired permissions and the disk several times successfully with no change.
I've also got the message "unlink of file /users/***/Library/Caches/com.apple.Safari/fsCachedData" in console.
Also when repairing permissions I've gotten this message: warning: SUID file "system/library/coreservices/remotemanagement/ardagent.app/contents/macos/ardag ent" has been modified and will not be repaired

MacBook Air shuts down when I close it

Whenever I close my MacBook, it shuts down instead of going into sleep mode. At first, I thought it was a problem with my MacBook not waking up from sleep at all, but if I use the Sleep function from the drop down menu, it will wake up normally.
I've looked around the community to see if anyone had a similar issue, but most people say they need to reboot it to start it up again, which isn't my case at all. It just does a typical shut down. How do I make it go to sleep instead of shutting down when I close it?

Triple-click anywhere in the line below to select it:
bzgrep 'Previous Shutdown' /var/log/system.log*
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
