MacBook wont power up , plugged in or unplugged
Anyone have these issues before worked fine last night
Have you tried resetting the System Management Controller? That is a good first step for power related issues such as this.
Best of luck.

My computer wont power up. I have unplugged it for 30 min. and replugged and it still will not power up. I cant get an service appt until Tuesday. Is there something else I can do?
Until Tuesday, the only thing you might try, if you already have and didn't state that you did, if this is the same outlet that you have used, and suddenly you lost power, try plugging your computer into another outlet and see if that works. If it works, either try another appliance in the outlet you are having trouble with, or check to see if a breaker has tripped.
If that doesn't work, well...you will just have tro wait until Tuesday.
Wish you the best of luck -
Macbook wont power on with AC power but Will with Battery
when i try to power on my Macbook it shuts off immediatly if i use AC Power but if i unplug the Ac Cord and use the Battery it does power on
Battery has an X on the display
i took it to the genius bar a few days ago and the tech took off the battery,held down the power button for 30 seconds then re-installed the battery
this corrected the X on the display for ONE DAYthen it came back
any idea what the problem is
and are both of the above things related?sorry wrong post, please ignore. too many threads with similar issues.

I just purchsed a nice Macbook off ebay. Its the white 2008 version. The seller swears it was working when he shipped it and is offering a refund if I cant get it to work (which leads me to believe he isnt lying) UPS dropped it off today. I hit the power button and absolutely nothing happens. By pressing the button on the battery it shows a full charge. He said he did a fresh install of OSX 10.5, and then shut it down when it started asking for personal info and then boxed it up and shipped it off!
I have already tried:
-Removing battery, power cable, holding down power button for 5 seconds, putting battery back in and plugging it in and got nothing. I also tried this without putting the battery in and running off AC power and also only using the battery with no AC power. Nothing worked.
-Found another article that said hold down command, option, P, and R and press power (didnt work)
-Also tried removing both sticks of ram and re-seating them and that didnt work either.
I will probably have to take it to the genius bar this weekend if I cant get it running. Just wondering if there was anything else i've missed I could try??Please make a Genius Appointment and take it in for service.

HELP! Macbook wont power up and keeps on ejecting.
I just updated the software on my new 1.83 Intel Core MacBook by clicking on that link under the apple-about this mac tab... after it installed all the software, a message popped up and said something about quitting all applications, shutting down the computer and holding the power button until the light flashes repeatedly. I've never seen anything like this but I did that and now the computer wont even start! The light on the front comes on, the screen blinks once and the CD slot keeps on ejecting .... over and over again.... There is NO DISC! If I put in a disc it tries to push it out and then takes it in... but you can still hear it ejecting... but this time more quiet, and now you cant actually eject the disc unless you turn off the power, turn it back on, and then quickly hit the eject button. I dont want it to damage itself so I just held the power button again until the whole thing shut off. I feel like punching the computer!
I also tried the to reset it by taking out the battery and holding the power button for 5 sec... then putting the battery back and starting it up... but that didn't do a got dam thing.
Does anyone know why my Mac crapped on me out on me?!
Thanks!

1.25 PowerPC G4/1.83 Intel Core MacBook Mac OS X (10.4.8) 768 MB DDR-G4 /512 MB DDR2-MacBookI Could Kiss You! That seemed to do the trick! I dont know why it cra pped out on me half way through this process.... but it updated now and all seems well. The only thing is that when I went to Utilities on my PowerMac... Disc Utilities doesn't seem to exist there... so I opened it up using the help tab and when I got to it, the FirmwareRestorationCD.dmg didn't even exist... it doesn't even seem to be in the computer. Have any idea about that one?
I had to download the dmg off the website.
Thank You so much for the help too! You Just saved my laptop and turned it back from a Huge Paper weight to a Working MacBook. -
Hi, when i push the power button on my white macbook it will show the apple logo, and the little loading thing below then a like circle with a line through it pops up...
i dont know whats wrong. can anyone help?I finally got my computer in to the genius bar. The hard drive is fried. I was told that they are using the same parts as pcs except for the Air. Since I am still under warranty, they are replacing the HD and fixing the chipped case but if I want to save my data I have to pay $50, even though its Apple's fault I'm losing my data. I saved a few pics to a flash drive but did lose some data. Now I'll purchase the extended warranty. I have only owned Apples. I had one of the first, the LCII. I still have 2 working computers, one about 12 years old and another about 6. I don't know if I'll get another 6 years out of this one.

Have a 13" macbook. wont power up. upon hitting power button, the computer sounds 3 long beeps constantly until you hold the power button down for 5-10 seconds. any thoughts out there?
Thanks guys, i just read a few articles regarding this. i pulled all the ram and tried swapping and reseating ram. it appears both chipsets are fine but one ram slot is bad. computer will boot with either chipset installed in the one good slot but neither chipset will boot in the other slot. bummer....

Macbook works fine when plugged in, turns off when unplugged.
Hello all,
As stated my 2008 Unibody 13 inch, serial number W8******1AX turns on and works fine when it is connected to power.
When it is unplugged it instantly turns off and turns its fans on full until it depletes the battery (so it is obviously getting power.. just not where I want it)
Since the problem began I have tried two new batteries, neither of which had any different symptoms.
Before this, the computer had an intermittent life, it would turn off when it saw fit, which got progressively worse.
I have followed the guides to resetting the SMC but have had no luck
I have been running it without the battery (to save it charging and discharging for no reason) and sometimes when plugged in without a battery
the magsafe green indicator light goes from dim to bright.
With the battery installed it stays bright orange until it is charged and then switches to bright green.
(I have tried it with another charger, same symptoms)

If this at all helps.
I'm at my wits end with this thing, I know it is getting on in age, but other then this, it has been flawless in its operation.
If anyone has any suggestions I would be happy to hear them.
Many thanks!!
<Edited By Host>There may be a hardware cause behind the symptoms you cite, so a diagnostic
is recommended to see which parts are weak or failed in the computer. A visit to
an Apple Store with Genius bar may be helpful, as they can perform testing there.
A call ahead or use their web page, to schedule an appointment, is advised.
In the US and Canada, the Genius bar at a retail Apple Store can perform
a diagnostic service, for no fee, even on Apple products without AppleCare.
See links:
Apple - Concierge
Genius Bar - Apple Retail Store:
http://www.apple.com/retail/geniusbar/
List of Apple Stores, cities, countries:
http://www.apple.com/retail/storelist/
Also authorized Apple service providers who can test, repair and guarantee their
work should be able to handle an out-of-warranty older Mac, within age limits...
Ones too old for the Apple Store could be serviced at a Specialist, instead.

Also another item, other than keeping the magnetic connections clean of
debris, grime, and corrosion, is to check the MagSafe Board or have it
checked as part of a greater diagnostic. This board is behind the port
that supplies the computer and the battery with power from the adapter.
When it partially fails or if/when one of the connecting wires or plug fails
you can find odd issues or partial use. The battery may charge but it
may not be able to power the computer, and other odd effects.

In older portable Macs, this was generally called a 'DC-in board' and as
such, you could read about it in an iFixit repair guide for the MacBook
model you have. These vary so the matching article is recommended to
see if that is something you may want to try. But I would have diagnostic
testing done and avoid additional damages from attempted DIY efforts.
There have been a few reports of other failure on the logic board that
contributes to a partial failure of the charging system, so about all this
may do is troubleshoot around the failure without finding an exact cause.
However it goes...
Good luck & happy computing! -

MacBook Pro goes out of sleep when unplugging the the power cord
When my MacBook Pro 13'' is in sleep-mode with the lid down and with the power cord plugged in,
if you the unplug the power cord the computer goes out of sleep-mode.
The same when it is in sleep-mode without the power cord, it goes out of sleep
when the cord is replugged in, although the lid is still down.
Anyone who have had the same problem?I'm having the same issue! I took it to the Apple store, they tested it all out and none of the techs were able to fix it or heard of the issue before.
They told me to reinstall OSx which I did and same issue. -
macbook pro 15" mid 2010 i spilled water on keyboard now it wont power on if the battery is connected and the keys on keyboard doesnt work it works fine with no battery and external keyboard if i order a battery and new keyboard will every else work again lik it did before
If you have records that show that you've taken your MacBook Pro in for a year to fix the machine, I would escalate the problem to Apple Customer Relations - unfortunately I don't have a number for Spain.
It would only seem logical to me that if you've been trying to have the machine repaired during the time that the 'recall' was in effect that you should be eligible for a new logic board. But only customer relations will be able to make that call.
Good luck - take the issue as high up the food chain as you can and see what happens.

I am having a problem when I plug my iPod into my macbook. When I plug the cable into my mac I get the following message - "Because a USB device was drawing too much power from your computer, your USB device has been disabled." CAN SOMEONE PLEASE HELP!
The rest of the message in the pop up window says "To prevent damaging your computer, the USB device drawing too much power has been disabled. Other devices may have also been disabled. When you disconnect the device drawing too much power, your other USB devices will be enabled again."

I plugged in my macbook pro power adapter and heard a loud bang. I checked the charger by opening it and found out the charger blew the whole mother board up. So i buy another charger, as i live in Egypt, that blew up the same way, please help.
You'll certainly need a new logic board.
If I were you, I would take the machine into your local Apple Store or an AASP and have them evaluate the problems and give you an estimate for repair. If you're out of warranty, be prepared to pay a very high price to get your computer repaired.
Good luck,
