MacBook Air not powering up

I Have a mid2012 13" mb air. About 3 months ago it would simply not turn on. I plugged it in, nothing. I tried various key combinations Including the shift/alt power button which cause a led on the MagSafe to Turn off and on - nothing. We were really busy in the lead up to a move. I tried the mba intermittently- nothing.
yesterday I reali there were some files I want on there. I thought I'd try again. Pressed power button, nothing. Plugged it in and it started up! I logged in. Retrieved my files. Backed up to time machine. Upgraded to 10.10 Which included several restarts. I went to turn it off and the power button wouldn't register. I shutdown via the menu. When I went to turn on, nothing. What's wrong with my MBA? Is the power button the only thing not working ? Is there any way around that?

You should also ask this in the MacBook Air forum. This is the forum for the white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

HT1338 Macbook air not powering up when pressing power on button, then after a few minutes it will power on.

My Macbook Air that I purchased in November of 2011 has just started to not power on as soon as I hit the power on button.
The Macbook Air will power on after a minute or so and works fine as of now.
This has happenned on two different occasions today.
Anyone have a reason why this would happen? Any solutions?
Thanks for your assistance,
Tommy

MacBook Air not turn on, after hard disk eject, without guarantee

Hello i have two macbook air not turning on,
after ejecting external hard disk, when macbook air is sleeping.
External hardisk ( 2.5 sata) have one ending of USB Type mini-B
and two endings of cable (one for data, other for power), of USB Type A
After next sequence,
-insert one tail of usb cable into macbook air, the second usb cable into 5v adapter (like iPhone usb adapter)
-after some time macbook air going to sleep
-without waking macbook air, pull out the cable what connected into macbook air
MacBook Air will not turning on.
even after this instructions
http://support.apple.com/kb/ts1367
In nearest AppleStore they say that there is a problem with logic part of notebook,
And the minimal price of repair will be cost half price of macbook air.
In other words, they say what they will not searching the problem of this,
they only will replace mother board.
Would you suggest other solutions ?
May be somebody else have this problem ?

OK. I wasn't quite sure. So, the first thing to try is Resetting your Mac's PRAM and NVRAM followed by Intel-based Macs: Resetting the System Management Controller (SMC). If neither can be effected then take it in for service as there has been a serious hardware failure.

Macbook Air not starting at all

Hi,
i have a MacBook Air 11" (mid 2011), purchased in Australia.
the other day I powered it down, unplugged the power, re-plugged, and it won't start at all.
no beeps, no fan noise.
Green light on the Magsafe connector.
Magsafe power works on a different Macbook.
checked Magsafe connection for dirt/debris.
tried with battery unplugged.
tried with SSD out.
tried SMC reset.
ordered and installed a new I/O Board.
i left it unplugged for a week.
still nothing,..
when it has power connected, the top/middle of the keyboard is warmer than the sides, indicating that power is getting in.
Unfortunately i'm in Mallorca, Spain, with no Genius bar available and only 3rd party repair shops.
So before I head off to be quoted an exhorbitant amount to replace the main board, are there any other magic suggestions out there ??
thanks in advance!

Back up all data before making any changes.
If you've installed something called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and reboot. You should do that even if the software is not causing the problem, because it's useless.
If you've installed an equalizer called "Boom" or anything similar, update or delete it and reboot.
If there's no improvement, or if you're not aware of having installed anything that fits the description, post again.

Apple MacBook Air 2011 - powerful enough for most tasks?

I want to buy the 2011 model of MacBook Air 13” 128GB, but I have some questions for you guys, would appreciate it if you experts have answers:
1) I'm currently on a two year old Acer Aspire 6920G laptop with 17”, Windows 7, Core Duo 2 (T5750 @ 2.0 Ghz) and 3 GB RAM - will my new MacBook Air feel one million times faster to use?
2) Can I later (easily/cheaply) upgrade the MBA's RAM to 8GB?
3) I mostly use web browsers, office software, IM programs, media players etc., but I will also use it a lot for electronic music making (with Ableton Live and virtual instruments/effects) and DJ’ing (with Avid Torq). I almost never do any heavy duty image work, and I rarely code/edit video - will the MBA be fast enough for the things I do most often, or do I have to get a MacBook Pro?
4) How often does the fan start up? And when it's on, how much noise does it really make when it approaches 6500 RPM?
5) I read that with Lion the fan is running more than with previous OS'es - can this really be fixed with booting in 32-bit rather than 64-bit? And what will that entail for the CPU power/battery longevity/software compability?
6) Is the graphics adapter in my current PC (nVidia GeForce 9500M GS) much more powerful than the MBA's Intel HD3000, or is it almost the same now?
7) Is it easy to run Windows XP or 7 in Boot Camp? I have a few Windows programs I'd like to continue using.
8) Should I alternatively use a few more bucks and get a MacBook Pro with SSD-disk? Is that less "locked" and more compatible with what might happen in the future, technology-wise?
9) Is it possible/cheap to switch the English keyboard to a Norwegian one next time I'm visiting Norway?
I have to make a purchase of a new laptop soon, so I'd GREATLY appreciate any answers. Since I have had software- and hardware problems with every PC I've ever owned, I frankly do not trust them anymore. So here we go then - Mac!

Let's see if I can help
1)The i5 Macbook air should be considerably faster than your previous laptop. Mostly because of the SSD and the i5 processor.
2)I'm not sure about the latest macbook airs, but previous models have their RAM modules soldered to the Logic Board, I don't think you can upgrade the RAM at all.
3)The MacBook Air might be fast enough, but Just, I would go with a Macbook Pro, mostly because it's easier to upgrade.
4)It will kick in several times but rarely at full speed, and it's not that loud. Would recommend a macbook pro for cooler running.
5) I didn't notice any difference between Lion and Snow Leopard regarding fan activity. Lion is a 64-bit only system, there is no way to boot in a full 32-bit environment. Compatibility can be an issue with some software, ie. traktor users have been reporting problems with external hardware running Lion, but updates will fix these soon.
6)They are at comparable levels, the Intel HD 3000 might even be better at some point. It's much better than the 9400m that older macbook airs had.
7)Yes, as long as you have the optional super drive to install it.
8)Yes, that would be a better idea.
9)I don't think so, never heard of people swapping keyboards on Macbook Airs or Pro's.
I'd buy a MacBook Pro if you are planning to keep it for long. It's more powerful, more upgradeable and runs cooler and quieter than the air.
Hope you get your mac soon!

MacBook Air crashes/powers down each time it's turned on.

I replaced OS 10.6.8 on my MacBook Air with Lion 10.7 when Lion became available last week.
Last night I noticed some odd behavior -- extremely slow "genii" minimization of screens, duplications of key strokes, and other anomalies.
Then today, each time I tried to boot up, as soon as the wheel stopped spinning and the desktop became visible:
Several windows automatically displayed -- windows I was working on when I shutdown earlier.
The dialogue box appeared with buttons for | Restart | Sleep | Cancel | Shutdown |
Almost immediately, the power cut off and the screen went dark.
"Reopen windows when logging back in" was checked, so I unchecked it. As a result, the Air now powers down without displaying windows or the dialogue box. It goes black almost as soon as the Apple logo and login wheel disappear. (I'm connected to the Power Adapter, so there's no problem about power.)
I tried several remedies that have worked in the past with OS 10.6+, but they're not working now --
Opening in Safe Mode: the system powered down while I was logging in.
Using Command-R to invoke Disk Utility: The system crashed before I could start Disk Utility.
Resetting my Power Management using the Shift-Control-Option + Power. The air powered down as soon as I turned it on.
Finally, I tried reinstalling Snow Leopard using the Install stick that came with the Air, but the system died before I could initiate a new install. What's going on?
First clue: I tried the fix-errors command, fsck, in single-user mode. It logged into command line fine, bu tbefore I could invoke /sbin/ fsck -fy as usual, a line appeared
: / root# AppleMCP89TMSpowerGatingdown(0)done
and the system died. Did something actually "power-gate down"? What's that mean? (MCP89 is an Nvidia video chip.)
Second clue: When I disconnected the Air's Power Adapter because of a lightning storm outside, the Air rebooted and then died, rebooted and died, etc. (I'm typing these comments on my Pro, of course.) It only stopped when I shut the lid.
Thanks very much for your knowledge, expertise, and suggestions for how to restore my Air or if it's a hardware problem, how bad it might be.

I experienced the same. Then I reinstalled OSX Tiger, put in my Snow Leopard Disc and restored my system from Time Machine. But OS X Lion constantly makes my system crash, so after the last crash (twice a week it did) I reinstalled Snow Leopard and restored what I needed to use from my Time Machine backup manually. (including finding hidden files for my mails, adress book, calendar etc).
I look forward to Apple telling us whether OS X Lion can run on EVERY Mac with an Intel processor from 1.83 Core 2 Duo. I have 2 Gb RAM and everything worked really nice and fine until Lion crashed. And the problem seemed that it has also corrupted my backups in Time Machine when Lion tossed round my files.

MacBook AIR not functioning correctly

HI everyone,
I have a 2014 MacBook Air running Yosemite and it has been completely functional until Friday morning when it rebooted itself without any input from myself. I was on a webpage and the screen went white before going to the Apple logo and loading bar. It stays on 50% and does not move... Occasionally after powering it down I cab get to the log in screen but cannot actually log in (the beachball of death spins and spins)
I have loaded it in Safe mode but cannot log in, have gone through Disk Utility (Cmd R) and checked the drives are functioning and I have reinstalled the OS. Just now i have done a PRAM check too... I am totally stuck now and if anyone has some advice then I am all ears.
Thanks in advance,
HQ78

If you have reinstalled the OS and it still doesn't work, then I'm sorry to tell you it's likely a hardware problem, which needs checking at a Genius Bar in a local Apple Store or at a Certified Service Provider.
Use this page to find one near you: https://locate.apple.com/country
If you have none nearby, I suggest you get it sent to Apple to get repaired. To do so, contact Apple Support here: http://www.apple.com/support/contact/

Macbook air not working unless plugged in?

I have a mid 2011 macbook air and it has had an issue of not working unless it was plugged in but mainly only working for a short about of time and then turning off suddenly and not turning back on unless pluged in or decreasing in power extremely and abnormally quickly. It happend a few times last year and twice i took it to a specialist specified by apple and twice i took it home with them having done nothing to it. They stated that there was nothing that the diognostics could see that was wrong with it. Eventually it fixed the problem itself and worked fine. just as long as i never ran it flat it worked fine. untill the other month i did that and now it will not work at all without being pluged into a power source. it has been plugged in all day whilst i have been using it and has not reach 100 per cent of power, it will not pass 98%. If the power cord accidentally falls out it turns of straight away, doesnt shut down just abruptly powers off. Never before has it been this bad. I have noticed it has also in this time it hasnt been working again its also been running noticably slower than usual. But that may just be me being parnoid. Im sick of taking it to get fixed only for them to tell me there is nothing wrong, because evidently there is. What options do i have? i just seriously need it fixed.

Your charger might be bad. If you have access to another charger, then try that one. If you dont have access, either find someone who does, or go to the Apple Store and purchase a new one. If the computer is still under warranty, take the computer AND the adapter and have them looked at.

       Bring it right back to the Apple store and tell them what they did to try to fix the problem did not work.. They are responsible for fixing it since it is still under warranty.

MacBook Air not reading USB Super Drive

My new MacBook Air is not reading the external USB Super Drive

I noticed you said "drive", and not disks. You do know that nothing happens until you load a disk into the drive, right?

Where can I find videos imported from iPhone to MacBook Air. not in iPhotos which is ridiculously complex and has no logic in how it stores photos

I THINK I have imported videos from my iPhone to my MacBook Air. but can't find them anywhere - they are not in iPhoto - which is ridiculously complex and there seems to be no logic

Did you look in iTunes?

MacBook Air not accepting new password.

I updated my MacBook Air to new OS and had to restart system, now its not accepting my password. I went online and reset password a couple of times but still cannot get Mac to accept latest password. Ideas?

You can reset your password with the install cd or usb ...
Follow these steps to reset a password when there is only one administrator account on the computer, or if the original administrator account needs a password reset. "Original" administrator account refers to the one that was created immediately after installing Mac OS X. If the original administrator password is known, that administrator account may be used to reset the passwords of other administrator accounts using the steps described above. These steps require an optical drive; if your Mac does not have an optical drive and you have a Mac OS X v10.6 Install disc, see below.
Start up from a Mac OS X Install disc (one whose version is closest to the version of Mac OS X installed). Usually, you can start from the disc by putting it in your computer, restarting, and holding the C key. Or, put it in the computer and click the Install or Restore icon you see in the disc's main window (after which the computer will start from the disc without you needing to hold C). Or, you can use Startup Manager or the Startup Disk preference pane to select the Install disc.
Choose a language, click the arrow button to continue,
Mac OS X v10.6 or later: Choose Password Reset from the Utilities menu.
Mac OS X v10.5 or v10.4: Choose Reset Password from the Utilities menu.
Mac OS X v10.3: Choose Reset Password from the Installer menu.
