Macbook Air won't power up after update

My son is on an internship in Alaska with his Macbook Air -- bringing the Macbook Air in to a "Genius" is not an option.
His Macbook Air (about 2 years old) has been working perfectly, but then this morning Apple pushed an update so he downloaded and applied it and now his Macbook Air will not power on. At all.
Is there a reset hole / button or anything he can do? Or is he just out of luck for the next several weeks until he comes back?
I cannot tell you which release the Macbook Air is, given that he cannot power it up to see, but he, like all of us, is running the latest OSX.

Thanks to Loner T and others in that thread I linked to above, my son's Macbook Air is now working again.
Doing the following 3 times brought it back:
1. Shut down the computer.
2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected
3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time
4. Release all the keys and the power button at the same time
5. Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

HELP! My Macbook Air won't power on!!

I have plugged it up and the power cord's light is green. It has ben a week and it still won't power on. What do I do now?

Were you able to find a solution... My wife's Air is doing the same thing I have tried all the KB suggestions of key combinations etc.. The power supply is green but the Macbook Air will NOT power on. Frustrated because I have a Dell laptop and never have had any problems as this Mac. So far she has had the Hard Drive fo so we replaced with a SSD $145... Then the hinges went $150... Then the LCD went $150 now it will not power on... from the looks of things it could be the Logic Board $850. There is no way I am sinking more money into this inferior product... I think Apple should be replacing this free of charge...This was all after the warranty was up...
Let me know if your problem has been resolved...

Hey laurelletoo,
Welcome to Apple Support Communities.
From what I gather, there’s an issue turning your iPhone 5 on after updating it. Take a look at the article below and try running through the suggestions that it provides.
If your iPhone, iPad, or iPod touch doesn't respond or doesn't turn on - Apple Support
Take care,

MacBook Air will not power on after going to sleep

I have a 13" MacBook Air (2012) that has been giving me some issues on and off lately. The past month or two, it has had a few instances where it would take a lot of time and work to get it to "wake up" after the lid was opened. A few times I had to hold the power and reboot it as it was non-repsonsive and would not display anything on screen (black screen). Then a few weeks ago it was un-responsive for a minute upon opening the lid but I eventually got it to come alive but it was very slow to get going as there were quite a few programs running and it auto-rebooted itself. Once I logged in, it did it again but this time it got hung up on the apple logo on boot and was in a cycle of trying to reboot itself but failed at the apple logo. I eventually got it into recovery mode and went into Disk Utility. It found some problems with the hard drive and fixed them. After that, it booted up fine and hasn't given me any problems UNTIL... yesterday, it won't even attempt to power on at all. It was working fine yesterday morning and I was only using Safari (no other programs running) then I closed the lid and left for a few hours with it just sitting there. I didn't take it with me, drop it or anything like that (In fact, it's never been dropped). I just left it right there where I was using it and closed the lid. I came back in the afternoon and opened it up and waited for it to come on but nothing happened. It wasn't even powered on as I put my ear up to it and listened for noise. I've tried holding the power button, I've tried Option+Power, I've reset the SMC, but nothing happens. I don't know what else to try. I believe this model may have a recall on the solid-state-drive but I'm not sure that is it as it should at least power on and display a folder with a "?" mark if the hard drive was bad. I'm wanting to attempt to resolve this before I make a 1.5 hour trip to the Apple store so any help and suggestions are welcome.
Things you should know:
It successfully resets the SMC as the orange light flashes green for a few seconds before turning orange again.
I've tried the charger with 2 different plugs with and without the extending cord. I've also tried booting on battery power only.
The power button is not broke as it recognizes it while doing the SMC reset.
Thanks so much for all your help, Silas

does the little light on the mag safe dongle turn green to indicate it is charging?
Are you sure you mean green? Mine is orange when charging and green when fully charged - always been like this with the 3 macbooks I have owned.

MacBook Air won't wake up after sleep

I've been reporting sleep problems with my iMac for a while in the past. No-one here would take it seriously (probably hardware, your reports are incidents, no-one else has these problems) so I just went away and I disabled the sleep function of my iMac alltogether, and I won't select the "sleep" button in the login screen anymore, or select "sleep" from the apple menu. No sleep no problem, right?
*Well, I bought a Macbook Air three days ago, and in those three days I have had TWO occasions already where I wanted to wake the Macbook after sleep* (closed lid) and it wouldn't wake up. All I get is the rainbow mouse pointer and the Macbook is unusable unless I reboot it.
Mind you, nothing is connected to the macbook but the power cable, and I find it hard to believe that my Macbook Air would also suffer from 'hardware problems' like my iMac alledgedly is.
In all my time using OSX 10.4 on my 17" PowerPC MacBook pro I have never had any problems, but since switching to Intel Macs with 10.5 I have these "sleep" problems all the time.
What gives, and can I expect Apple to do anything about this problem that I've been having since I bought my iMac more than a year ago, and is now also spoiling my MacBook Air experience?

I have a Macbook Air and it also frequently (6 times out of 10) will not wake from sleep mode, only way to revive it is to hold down power button for 10 secs and force a restart. VERY FRUSTRATING!
I also occasionally use an external Apple 24' Screen (Non LED) and find that the MBAir will often freeze when you plug that into it or unplug it from it.. Perhaps I have a hardware fault on the MB Air? Or will this be fixed in software?

MacBook Air won't turn on after repairing permissions

Hi everyone!
I tried to update the software on my new MacBook Air; the updates started downloading and then it stopped because of a network problem. For some reason, my network wouldn't accept it so I thought *checking the permissions*; I asked for a repair, had the time briefly to see the long list of incompatibilities and then, bof, the Mac turned off, as simply as that. I did everything the Troubleshooting page suggested here:
+Press the control key, the command key, and the power button simultaneously and hold for three seconds to try to restart the computer.+
+Reset the PRAM. After pressing the power button, hold down these keys simultaneously: Command-Option-P-R, until you hear the startup chime at least one additional time after the initial startup chime.+
+On the MacBook Air, press (left) Shift-Control-Option along with the power button once. Note: You must use the keys on the left side of the MacBook Air keyboard.+
the only thing I can say is that at times I could hear the fan turning, but although I pressed the luminosity & sound buttons nothing changed.
I wonder if it's a software problem.
I am frustrated as ****, especially as in my country I don't trust anybody to get close to it
Any suggestions pleeeeeeease?
Thank you!

Hi Guys,
I'm having the same issue with my MBA. Basically, I press the power button, the SIL light flashes once for about 5 seconds, then goes off, then comes back on and I can hear the fans spin up (I have removed the back cover to confirm this). The screen stays black, the keyboard doesn't show any signs of life and the SIL light just sits there. I've tried the usual SMC, PRAM reset, all to no avail. Thought that maybe it could be a POST or boot ROM failure... Any ideas?
Thanks,
Mark J

Airport won't power up after updates 5.5.2 and 7.5.2

I updated this afternoon via Software Update: Airport Utility (to v. 5.5.2) and Airport Extreme firmware (to v. 7.5.2). Everything seemed fine, noticed no problems and later I shut down my main computer for the day.
When my wife came home later, she couldn't get an Airport connection on her MacBook Pro. In the process of troubleshooting, I went back to the Base Station and found it was off (no light at all). It simply won't power up at all. Unplugged it, replugged it, etc.
Seems like too much of a coincidence that my unit would have just flat-out died after these updates.
Anybody know what's up?

Thanks Bob, I'm afraid you're right. I didn't know that a firmware update could fry hardware like this! It's just too much of a coincidence to be a... well, coincidence. (Especially now that I see all the other people having problems today after this update.)
I've also reported the issue to Apple via the link you posted in another thread: http://www.apple.com/feedback/airportextreme.html

My mbp won't power up after update.

after running an app store update, (Xcode) my mbp won't power up and the battery lights are showing flat even though it was on charge over night.
the update was taking a long time, and it had a message saying something like deleting old files.
i went to bed and left it over night.
when i went back this mornng it had powered down, and the drained the battery even though it was plugged in.
now i can not power up, and i have tried the smc reset.
please help.
many thanks.

This is the standard Apple support article for your situation. If you cannot try another adapter to try, I suspect a trip to an Apple store genius bar is in your future.

Macbook Air 10.8.2 crashes after update. Gave a message "Some updates could not be performed due to an error"

3 of our mid 2012 Macbook Airs10.8.2 crash after update. Gave a message something like this "Some updates could not be performed due to an error" and now when rebooting I see panic...Unable to find driver for this platform...
I don't want to udate any more of these (I have 31) until I know what is causing this problem. Will I have to reimage these machines?

If you don't already have a current backup, back up all data, then reinstall the OS. You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used to upgrade.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode.

Macbook Air won't turn on after SMC reset

Hello,
The fan on my macbook air had suddenly started becoming very loud intermittently even with no apps running. I tried restarting the computer several times, but the problem persisted for about a week. Looking online, I found an SMC reset might solve the problem. However, after doing the reset, my Macbook now will not turn on at all. There is no startup chime or lights when pressing the startup button. The only thing that happens when I press the power button is that the light on the adapter turns from orange to green for second before turning back to orange.
I have an appointment with the Genius Bar tomorrow, but would like to seen if anyone has any suggestions. Thank You

Try the SMC again:

Then try a Safe Boot;

My MacBook Air won't turn on after it fell from 1ft high.

My MacBook Air fell about a foot and got a little wet on the back behind the screen. I don't think that's the problem but I'm not sure. I wiped it off and tried to turn it on but it won't come on. I can hear the fan and other noises but the screen doesn't show any sign of life. What can I do? I live in Belize and the closest apple store is in Florida.

I can pretty much guarantee you that dropping a computer from about one foot as well as getting it wet would void any warranty you might have. Warranties generally protect against manufacturing defects, not actions caused by users.
I'll leave it to hardware folks to discuss PRAM and other stuff - I'm more of a software / programming person. But my view is whatever measures may or may not temporarily work, once the poor machine has suffered these fates, it will never reliably work again.

11" MacBook Air won't start even after SMC reset attempt

I press the power button on my Air and the Apple sound chimes, a dimmed grey-black screen appears and nothing else. I have combed through the communities and the suggestion was to do a SMC reset. I followed the instructions exactly and nothing changed. I initially plugged into my Thunderbolt monitor and ultimately plugged into power with the standard MagSafe cord. Neither changed the outcome. I have had this Air since November 2014.
One of my questions about the SMC reset was how could the device recognize actions while the computer is powered off?
Please help me!
11" MacBook Air, OS X Yosemite (10.10.2)
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

You have to take the computer to the Apple store to have it checked out.

One of the keys you press when resetting SMC is the power button.

MacBook Pro won't boot up after updating to Lion

I just updated my MacBook Pro to Lion. After install restart the computer is stuck on the white screen with the apple logo and spinning wheel. I manually restarted it after 1 hour but that didn't solve the issue. What do I do? Any advice would be greatly appriciated.

That sounds like the case. Good Luck.
check this link:
http://lmgtfy.com/?q=Lion+boot+disk
there is a ton of information, step by step. I am sure there is probably something here in these forumns on creating the boot disk.
Again I would start with a clean install of Lion off of the boot disk you create.
FYI I started with Snow Leopard time machine backups updated, then cloned my existing drive to a FW drive before installing. During the work day and in IT, It was a savior to target boot from the firewire drive to address employee needs when I was having Lion lock up issues from the initial install.
Wipe and install clean so far so good. No lock ups. And USB flash install was super fast. Then brought my apps over, or re-installed. This way everything was clean.

MacBook Pro won't start up after update

I just updated my MacBook last night and now when I turn it on it gets to the grey apple screen and shuts down.

Reset PRAM: http://support.apple.com/kb/PH4405
Try a normal boot.
Perform a Safe Boot: http://support.apple.com/kb/PH14204?viewlocale=en_US
Try a normal boot. If it boots reliably with a Safe Boot but not a normal boot then it is probably a software issue. Post back for more instructions.
If you do not have a recent backup create one in case your disk is failing. (Post back if you need instructions on how to do that w/o booting OS X.)
Boot in Recovery Mode. (Hold down the Command (⌘) and R keys as your computer restarts. If you are running 10.6 or earlier boot from an installation disk.) Run Disk Utility. Click on the upper left system disk icon. Does S.M.A.R.T. report “Verified”?
If it does not say “Verified” then the disk or the disk cable is failing and will need to be replaced. As noted above, if it is failing the first priority is to back it up. Post back for more instructions for emergency data recovery and replacing the disk or its cable.
If the S.M.A.R.T. status is “Verified” then repair the disk. Click on the icon underneath and indented to the right, usually called “Macintosh HD”. Repair Disk. It should finish normally with a green OK message. If it does not try to repair it again.
If it will not finish with a green OK message then having a backup is again essential. The remedy is a clean install: backup, reformat the drive (erasing all the data), reinstall OS X, and then restore form the backup. (Post back if you need instructions on how to do any of those steps.)
If it repaired all errors (green OK) and is still not booting normally “Macintosh HD” icon again and Repair Permissions. Ignore the numerous messages in black. It should finish with a green OK message. If not, run it again.
Once you have repaired the disk and the disk permissions, if it will not boot properly, reinstall OS X:
Boot in Recovery Mode and then install OS X.
If it is still not booting normally after the reinstall then, as a last resort, perform a clean install. Make sure you have a current backup (Time Machine or a clone). Boot in Recovery Mode. Use disk utility to erase the system disk (deleting all data). In the Erase tab click on Security Options… Select “writes a single pass of zeros.” This will write to every block on the disk, mapping out bad blocks. Install OS X. Reload your data from the backup. (On the first boot the Migration Assistant should as you to restore from your backup.)

My macbook pro won't start up after updating it

I Have a macbook pro with Mavericks (I don't remember exactly which one) which I bought in 2012, yesterday night I updated it and it restarted but it took forever and I thought it was installing something, so I left it like that all night and day and is still in the gray screen with the apple logo and the wait spiral. I got worried so I entered the disk utility option and checked the disk, and it said everything was Ok. When I restarted it again, the gray screen never left so I tried with the "safe rebooting" ctrl + cmnd + V and the screen shows now endless rows of "disk0s2: 1/0 error." and it's been like this for about half an hour now, I'm really worried I'll my data.

An 1/O error cannot be repaired by Disk Utiity.
That requires a more robust disk utility such as DiskWarrior
You can contact the developer using their email address here.
Best to get their recommendation before purchasing.
Hopefully you have a backup to restore from once the drive is either repaired or replaced.
