Macbook air won't start without charger if powered off for at least 5 hours.

Hi,
I have macbook air and it doesn't turn on if I shutdown it for at least 5 hours and next time I need to start i have to plug the charger just one time after that It starts and can be used for whole day.
I am not sure what the problem is I charger battery to 90% before shutting it down.
Yes my battery cycles are too much. Details are :
Health Information: Battery cycles : 785
Condition : Normal

Hi there abhishekgahlot,
You may want to try resetting the SMC as an initial troubleshooting step. Additionally, take a look at the battery condition. The articles below have more information.

Macbook Air won't start up after shutting it down for about 20 minutes

I shut my MBA for about 20 minutes then I tried to turn it on but it won't let me, it is at 49% battery. I pressed the on/off button then waited for about 30 seconds but nothing happened, then i waited for longer and pressed again then it turned on. (I also heard the fans) Can you guys please tell me why this happened and how can I deal with it next time? Thanks a lot.

I would recommend a SMC reset.
SMC RESET
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.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

My MacBook Air won't start up. It's completely powered, yet when the white screen with the apple shows up upon me turning it on, it shuts right back off. Can someone help?

MacBook Air won't start up even though it's fully powered. The white screen with the apple logo appears when I turn it on, then it shuts right back down. Can someone help me?

My MacBook air won't start? Black screen

I closed my MacBook air and when I opened it again it won't start. I tried to reboot it but the screen stays black. I hear the ventilators turn slowly when I try to turn it on but nothing else happens. The light on the macsafe charger is on. A few hours earlier the charger won't work but the MacBook worked well. After a while it worked again and I charged the computer and surfed on it without the charger later. It happened a little later. I tried to reset the PRAM and the SMC but the screen still stays black. I tried to start it with a external hard drive but nothing. I tried to connect an other screen but still nothing. I'm desperate!
I have an appointment at the genius bar next Tuesday but I hope it will start again until then.
What can it be. Is it possible that the charger had a diffect and that something overheat?
Thanks in advance for your help. And sorry for my English, I'm french.

Hello!
My friend is experiencing this very issue and your response would be most helpful as he is out of warranty. Please do keep me posted!

Laptop won't start without charger!! (battery fully charged but worthless)

My Macbook Pro won't turn on unless its plugged into the charger. If I turn it on without it being plugged in, it'll begin starting up, then immediatly shut down (the battery is fully charged). Does anyone know how to fix this problem? It's really getting me worried!!

I updated it about two to three times and would still experience the same problem.
Why update 3 times?!? If you run an update, and it installs normally, that it - done!
There's a world of difference between running BatteryUpdate 1.2 and installing a new battery. In fact, if you read the linked page above, it states that the after you run battery update if you experience any of the listed problems you should contact AppleCare. Their first step will be to replace the battery. Could it be a logic board problem? Sure. Is that the first thing they'll do? No. By that reasoning, the first thing to try if your car fails to start on a cold morning is to put in a new engine...
So, to the OP, contact Apple - or better yet, if it's convenient, go in to an Apple Store. Get a new battery. If the problem persists, go from there. The advantage of taking it into a Store is that they'll test it on the spot.

Macbook air won't start

Hello, Need help with a macbook air, running mountain lion. I don't know which version because my computer won't start.
It appears to boot normally all the way to where the desktop can be seen and the cursor is drawn properly and the cursor can be moved around using the touchpad. It may or may not login to my wifi network according to the icon in the top bar. I see all the normal icons in the bar at the top - including if I see that the wifi has connected, I also see that the airplay icon appears there.
However, nothing on the menus can be selected using the touchpad by pressing or tapping or any gestures other than moving the cursor around.
The touchpad does however tell if there are 2 or 3 or 4 fingers down because if I for example put 4 fingers down and swipe to the left I get the dashboard, and if I swipe up with 4 fingers I also see the correct screen. And if I put 2 fingers down the cursor does not move which is correct - and if 3 fingers down and move, the cursor moves which is also correct (no windows can be opened though so there are no windows to move around).
Also, the applications popup bar at the bottom of the screen does not pop up when the cursor is moved to the bottom of the screen.
Looks like the keyboard is working OK because if I push the power button in the state decribed above, I get a popup window that asks if I want to shut dwon the computer, and presssing the return key chooses the highlighted choice (shut down).
So... pretty useless computer right now, it will start but can't choose anything or open any apps.
Thanks for any help.

OK got it to work... used external trackpad and for some reason it would operate corectly. THen the internal trackpad also started working suddenly also. So problem solved, but no idea what caused it to start working.

Macbook Air Won't Start Correctly

WHello.
I have the previous version of the Macbook Air. When i turn it on, everything seems to be normal. I input my username and password and login.
But then, the icons on my desktop won,t show up. The dock and the top tab is in place. The computer is working -somewhat slowly- but my icons on the desktop won't show up and my keyboard shortcuts don't work. For example, i had command+d set as show desktop, but this command won't work. Neither does the right click with two finger tap on the trackpad.
What could be the problem ? Any suggestions ?
Thanks in advance.

My MacBook Air won't start it's grey with apple logo Howe do I fix this?

I have 2008 MacBook Air today I can't start up. When I press the power button it shows gray screen with apple logo and that thing spinning . How do I fix this?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

Macbook Air won't start up past the "apple" page, and has a spinning icon. help!

The computer was left on for over a week while I was out of town, came back and it was slow, then it started doing the "spinning beach ball" so I shut it down and now it won't start up again.

Hey Sarah.
The spinning beach ball of death is a tricky issue to fix.
You can delete everything in the caches folders located at:
~/Library/Caches
/Library/Caches
Also try an SMC/PRAM reset:
PRAM RESET:
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
SMC RESET:
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.
If you still boot to the apple screen your next option is to boot to the Mac OSX install DVD and run a disk check/repair.
Hold down option with your OSX DVD in your drive, click on the cd that appears, boot to the OSX DVD.
Click on utilities in the menubar, go to disk utility, select Macintosh HD, run a check/repair.
If this fails you'll need to run the Max OSX installer and reinstall your Mac OSX.
P.s since you have a Macbook Air your install DVD is the usb stick you would have got with your MacBookAir.

My MacBook Air won't start up, only black screen no logo

I've had my MacBook Air since Christmas 2014. I have not spilt anything on it, I have not dropped it and the charger isn't broken.
Yesterday my computer wouldn't turn on, it was working the day before so I don't know why this was happening. When I turn on I mean:
Press the turn on key
I hear the chime for it to turn on
then all of a sudden
no logo only black screen and then nothing after it.
I really don't want to reset it because it has all my school work on it and very important pictures on it.
Is there anyway we can fix it? I've looked on this website many times and others and nothing has really helped.
If you have anything new please reply ASAP.
I need this fixed within 2 weeks.
Thank you.

Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the 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.
Reinstalling OS X Without Erasing the Drive
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility 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 Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X 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.
Alternatively, see:
Reinstall OS X Without Erasing the Drive
Choose the version you have installed now:
OS X Yosemite- Reinstall OS X
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

Macbook Air won't start after Yosemite update

Hi all,
I have a late 2013 model macbook air (just out of the 1 year warranty). I updated to Yosemite last night and to complete the install I restarted the macbook when prompted, but it never turned back ok.
I can now hear the macbook trying to start up but it does nothing. I have tried to reset the SMC and I can see the power adapter change colour from orange to green for a few seconds but this does not appear to fix the issue.
Any help is appreciated,
Peter

If that doesn't work, this link may help you identify the problem
https://www.ifixit.com/Wiki/MacBook_Air_Troubleshooting#Section_MacBook_Air_won_ t_turn_on
If you still think its SMC issue you can try manual SMC Reset (At your own risk ). Steps are..
1. Open the lower case
2. Disconnect the battery connector and after few secords connect it back and close the lid

Hi, I just had a session with an apple support staff and now my Macbook Air won't start up. What shall I do?

I contacted Apple support because I couldn't download apps on iTunes.
I got called back by Apple who redirected me to a technician.
The technician had access to my macbook air screen and via her directing me on the screen and via telephone she had me remove a bunch of stuff from my computer.
After that it seemed initially that the iTunes problem was fixed because the iTunes box showed that it was downloading the app. But it just said it was dowloading it but there really wasn't any progress visible.
So I decided to restart the computer but it would never start back up.
I scheduled an appointment at the Genius bar closest to me for tomorrow.
Is there anything else I can do/try?

Since I do not know what she had you remove it will be hard to say what exactly to do. If your original problem was automatic downloads here is what apple says.https://support.apple.com/en-us/HT202180 First i would try a pram reset. Command/Option/P/R keys at startup for three chimes. Then if no startup Go to recovery. Command R or Option R at startup. Then use the utility option and check /repair startup volume and also permissions. If still no response you might have to use recovery to reinstall your operating system. You should have your files backup up even though a reinstall does not normally delete personal files.

My MacBook air won't start up

I shut down my MacBook Air last night with no problems. This morning I pushed the power button and I got a circle with a slash through it and a rotating Apple. My OS X won't load. I chone the disk utility repair (based on suggestions on other forums) and it's been "updating boot support partitions for volume as required" for over 30 minutes now. Not sure if this will work. My next option is to reinstall the OS X Maverick. I'm worried because I don't have a backup and need the files on my laptop (dumb move and will never do that again). Anyone else have problems like this? Could you get your files off the hard drive?

Welcome to the Apple Support Communities
What are you referring to with "changing colours"? During startup, you should only see a grey screen with the Apple logo. If the color is different or it changes, the graphic card or the display is damaged, so take the computer to an Apple Store

Macbook air won't start without charger if powered off for at least 5 hours.
