Macbook won't power up

I have a Macbook Air 11inches, Late 2010 model. I haven't use it for a couple of months. When I decided to use it, it won't power up. I used different adapter still no luck. I notice that the adapter has a low green light, not the kind of light that I have seen before. I brought my MBA to some techie who knows apple they said I have a busted battery. I am still confuse, though its already 1 year and half old since bought it but I didn't remember if I drained the battery or something. All I know the last time I used it, I properly shutdown my MBA before I leave in its proper place. Please help, I really need my MBA now..

Welcome to Apple Support Communities
With the charger plugged, does the Mac turn on? If not, it's possible that the logic board has failed. If that's the case, it will be an expensive repair.
The green battery indicates that the battery is full, but if your Mac doesn't turn on with the charger plugged, it's not a battery issue

My old macbook won't power up - help please!

I have an ancient macbook, from around 2006, and it's been chugging along just fine. Suddenly, it just won't power up at all! Power adaptor shows a green light at plug in, so the cord is working, but no fan sounds, no lights, nothing when I try starting. I've tried that SMC reset, but still nothing.
Is there anything else I can try? If not, does anyone know if a good apple repair shop should be able to recover my data? I've been an idiot and haven't done a back up in a few years.
Thanks for any help anyone can provide! I'm going to purchase a new macbook air, but REALLY need my data from the old one if at all possible, so hoping I can get it started and/or have a repair person salvage the data.

MacBook won't power up, Thanksgiving Blues

I have, what I guess, is a 13in MacBook thats about 3 or so years old running Snow Leopard. I left the machine in sleep mode while I was away for a few days, and now it won't power back up.
I've charged the battery all the way, get full indicator lights and everything, and the mag-plug-thing shows a green light. everything appears normal, except the **** thing won't power on. I've tried resetting the SMC and out of ideas...
Am I correcting in assuming the power adapter and battery are both fine, since they light up and charge? So confused.

If both items light up then it is likely fine. Do you get any power at all? Does the machine chime? Do you get the LED light on the front lighting up? Take it to your nearest Apple Store or Apple Authorized Service Provider and they can troubleshoot further.

MacBook won't power on, even when plugged in

Not sure what's going on. My white MB is my secondary computer, I've only had it for a few months. I brought it on a trip a couple of weeks ago and it was fine. It's been packed up in its case since I've been home, so I'm sure the battery is probably dead. I took it out today, and plugged it in, but it won't power up. Even if the battery is dead, shouldn't it turn on when it's plugged in?
I get nothing...no sound, no flicker, no nothing. Help? I have an Apple store close by, so that's not a problem...just want to make sure I'm not missing something dumb before I head over there.

The Apple store called this morning and confirmed it was the logic board that went bad, and that it was fixed and ready to be picked up. I stopped by to get it after work and I'm back up and running again...and I couldn't be more pleased with how Apple handled the whole process. Less than 24 hours from the time I dropped it off to the time it was fixed and ready for pickup.
Kudos to the San Tan Village Apple Store in Gilbert, AZ!!

How can I back-up my hard drive when my MacBook won't power on?

The other day my 2 year old MacBook Pro just turned off abruptly and has not powered on since. I took it to the Apple store today and they determined that it's more than likely a problem with the logic board since its not getting power at all and now I'm going to have to get that replaced. Before I send it away I need to backup my hard drive to an external but have no idea how to do that when it won't even power on. We don't have any other working computers in the house but if I absolutely need another computer to accomplish this, I could try to ask a friend to help me out.

I lost power to my PC. Neither the battery nor the AC adapter works. I'm shipping the laptop back to the manufacturer for repair, but they advised that I should back up my hard drive before shipping it. Is there a way to back up my hard drive without having any power on my laptop?
Do you have another machine?
You can remove the hard drive and put it in an external enclosure in order to copy the contents to another machine.
If you don't have another machine, you unfortunately are going to have to find someone to back it up for you.

Macbook won't power down

Bought a brand new Aluminum Macbook 4 days ago, and it worked perfectly for the fisrt 3 days, but today it has decided to not power down or let me log off. When I try to shut it down, it acts normally at first, closing out all my open apps but then it just does nothing and won't turn off.

Have you tried holding down the power (on/off) button to force shut down?

Please Help! My Macbook won't Power up after I cancelled an update!

I was installing updates on my macbook when i accidentally pressed the power off button. Now everytime I try to turn it on, a screen appears and says, "You need to restart your computer. Hold down the Power button for several seconds or press the Restart button." I have done both and nothing has worked! I have tried to take the battery ou and press for 10 seconds and everything in the book...I dont know what else to do! I have had this macbook for less than a month! Please help!

Take your original DVD installation disk that came with your MacBook and use that to boot your system (turn your system off, GENTLY insert the DVD until you feel a little resistance and then press the power button, then make certain that the DVD has been taken fully into the slot and immediately after that hold down on the "c" key so that the system boots from the DVD) . Once you reach the install screen look for the Utilities menu and select the Disk Utility from that menu. Once you enter the Disk Utility try a verify disk operation and if that reports errors then attempt a repair disk operation. After this, do a verify permissions (from within the Disk Utility) and repair those if needed. After this quit the Disk Utility and when you return to the installer screen quit the installer while holding down on the mouse button (or trackpad button), the latter will cause the DVD to be ejected and the system will again attempt to boot from the internal hard drive.
If after these operations you still can't boot from your hard drive then you will probably have to do an archive and install using your original installation DVD.

Help, First Gen MacBook won't power up! =(

This is the second time this happened, I had the Macbook in sleep mode, I opened it up and mistakenly pressed the power button thinking it was still off, and the Macbook wouldn't turn on.
I fooled around with it and got it to power back up by holding the power button; however this time I did the same exact thing and now I cant get it powered up. I tried the power management reset by disconnecting the power cable and battery and holding down the power button for 5 seconds, and still nothing.
The warranty already has expired on it, so the last thing I want to do is go to the apple store and have them give me bad news.
Please some one help. =(

I have a macbook and when I power it on and then select myself as a user...It won't power up. It stays in the white screen with the apple logo. I am online currently under 'guest user'. Is there anything I can do from the keyboard to fix this??? Help!!!

Could you specify the model of MacBook and the OS X it's running, please? Some of the advice or references vary along with the system, so this could be helpful to formulate a reply. I've never used a Guest User selection, but do have more than one User.
If the computer does not have an optical drive, you may be able to boot it into a recovery disk mode or something; in an attempt to see what is wrong and maybe fix it.
Good luck & happy computing!

Help! Macbook Pro won't power up!

Hi, I have a new 2011 MBP 15" (1.5 months old).
When its up and running it works fine, and I'm able to shut down and restart it normally. As soon as I leave it off for more than a few hours (usually this happens overnight when I shut down the computer before going to bed)
The next morning the computer won't power up at all. When I press the power button I can hear something whirring/spinning and then 3-5 secs later the power just cuts off. The screen doesn't even light up, I don't get to hear the apple chime at all. Repeated attempts to power up the system get this same result.
I suspected it was due to cold weather (winter in Perth now). I find that every cold morning if i warmed up my macbook placing it near the heater, it will be able to boot normally after it has warmed up. But if ever the machine gets a chance to cool down, it goes into a coma? This happens when I put the mac to sleep and am away from it for more than an hour, it won't wake up!
This is so dissapointing to come from a product that comes at such a premium price. I hope I can get some help on this! It's really really frustrating.
I am reset the PRAM and SMC several times and they dont seem to do the trick. I ran the apple hardware tests, even in extended mode and they all detect no problems. Hellpppp

How cold is cold where your MBP is? In any case take it to an Apple store or AASP. If none availanle call AppleCare.

MacBook won't start on battery/shuts down when power adapter is removed

Help & advice needed please.
My MacBook won't start without external power, it gives a whir then a click then nothing. Once started up, if I remove the external power it just shuts off.
The battery shows at 98% & charging. Coconut Battery shows the following:
Current battery charge 4126 (& increasing as I type)
Maximum battery charge 4200
Current battery capacity 4200
Original battery capacity 5200
80%
Battery loadcycles 111
Age of your Mac 6 months
Charger connected yes
Battery is charging yes
Does anyone have a clue why the Mac won't power itself on the battery when everything else seems like it works?
Cheers!

As of today, my MacBook and I have been together for 40 days. Yesterday, while I was happily surfing (on battery), it powered down with no warning. Okay, these things happen. I plugged it in, restarted, and all seemed to be fine. Battery was about 70%. I did other things on my other machines and when it was about 90%, unplugged it and everything was good. This morning after using it unplugged for 1.5 hours it did the same thing, but decided to only work with the power adapter, not on battery alone. When trying to boot without AC, it would try to spin the CD and then fall back into off. When on AC, if I pulled the adapter, it would last two seconds and go blank. I made an appt. with the Apple store (Fashion Show Mall, Las Vegas) for 3:20pm. I got there right at 3:20pm and the monitors showed I was 5th in line. Store was fairly packed, at least one patron at every display item. Monitors also said the next MacGenius appt. was "approx. 8:30pm." Glad I made an appt! I was served about 15 min. later, during which time the monitors had changed to "No more MacGenius appts. available today, please try tomorrow." However, one guy came by without an appt. and was told he would be put on standby and to come back in 30 min.
Once I explained my issue with my MacBook battery, my Genius tried one of his batteries. "I just want to make sure it's your battery and not your motherboard." My machine worked fine, so he said "No problem, I'll have you out of here in 10 minutes." He got me a brand new battery, tested it, and put my old one in a box on the rear counter with four others. He pulled the serial number from the "About this Mac" area, didn't need my receipt for purchase date or anything. I had even printed this page: http://www.apple.com/support/macbook_macbookpro/batteryupdate/ to use as ammunition, but didn't need it. He did approve highly of my dashboard widget "iStat pro", available here: http://islayer.com/.
So the battery issue is a very common problem, and one that Apple has tried to deal with as painlessly as possible for the consumer. My Genius did ask if the battery showed an "X" in the icon bar, and I said no. Just wouldn't run on battery. On the way out of the store, one of the 3 MacBooks, in fact the one closest to the door, had an "X" on the battery icon. When I unplugged the power, it shut down immediately! The moral of the story is to contact Apple immediately with problems and give them a chance to fix them. Hope this helps others.

My MacBook won't start up properly, and I suspect it may be the result of a power surge due to faulty wiring in my apartment. Is this the kind of thing that can typically be repaired, and if so, at what price?

My MacBook won't start properly. It seems to run, but the screen won't light. I suspect the cause is a power surge due to faulty wiring in my apartment. Is this the kind of thing that can typically be repaired, and if so, at what price?

you need to bring it somewhere so it can be determined exactly what is wrong with it and then an estimate can be provided.

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...
