Macbook won't start or charge unless I disconnect and reconnect the battery connector each time .

I have a late 2011 model Macbook Pro, 10.7.5 OS and I've had no issues whatsoever up until a week ago. The night before if stopped working I did everything as usual, did some HW, emailing then I shut it down. I woke up the next morning and it wouldn't turn on so I figured it was dead, so I got my charger plugged it in and got no light, green or orange. What I got was a faint green blinking on the charger light and my battery level indicator wasn't working. I thought it was my charger but it wasn't because worked fine on my girlfriend's Macbook.
I googled and tried PRAM and SMC to no avail. When I tried the SMC I didn't take the battery out I just disconnected the connector (Don't know if it makes a difference) and Voila it worked and I thought I fixed the problem. I turned it off and the next day the same thing, I have to disconnect and reconnect the battery connector each time for it work. Other than this issue I have no problems, mac runs fine while it's on and I shut it down or restart it for awhile after I reconnected the battery but if I try to turn it back on or restart it hours after I've done that then it won't work . One thing I may add is after I reconnect and plug my charger in, the light is green for about 5 seconds (even though it's not fully charged) then turns orange .
I'm guessing I need a new battery or logic board , but I'll keep my fingers crossed .
I won't be able to set up an appointment until next week but I would like to see if I could get any help here in in the meanwhile.
Thanks !

Hi, I dont know if this may be the cause as i too have the same problem. But it only occurs after i disconnect my Iphone from my macbook pro.
The Macbook has worked perfectly and then all of a sudden last week it started to shut down after i would disconnect my Iphone 5.
The mac wouldn't restart, charge or anything.
I tried all the trouble shooting reccommended, Shift Alt command button combinations. ( there were a fair few ) None worked.
Then i found out about disconnecting the connector.
This fixed the problem.
But alas, It done it again after my next sync.
This has done it 4 times now. And only when i disconnect the iphone after using itunes on the mac. I done it all correctly 3 times and the 4th time i just pulled it out with out ejecting from itunes, but still done it.
The iphone Syncs perfectly. I get everything i want onto the iphone. But for some reason as soon as the cord is disconnected from the mac BOOM. Dead mac.
If i leave the cord and the phone plugged in but still eject the phone it doesnt shutdown tho.
I found if i shutdown the macbook, then disconnect the iphone cord once the mac is completely shut down then my mac will start back up again with no problems.
As i said i dont know if this is the cause of your problem and if it will help you or not? But if not, maybe it will help someone else out who finds your post?
Hope you get your problem sorted

MacBook Pro keeps shutting off when locked or shut. It does not turn back on unless I disconnect then reconnect the battery connector.

I don't want to have to take apart my laptop every time I need to use it. Is there a permanent solution to fixing this problem? Trying to avoid a trip to the Apple store.

If you have a Time Machine back up you can try Restoring it, then run your software update before opening and see if it will download the Mavericks compatible version.
I am not to hopeful here. There is no stand alone Safari download for Mavericks.
You would have to reinstall the OS. It should not touch your user files when you install on top of your existing OS.
Always prudent to have a backup.

My MacBook Pro blacks-out when I plug in any USB device. It then doesn't start up until I open the bottom casing and reconnect the battery connector and start it up again. Why is this happening and how do I fix it?

what could be the possible causes for this?
Also, when it is at its blackout stage, the macbook charger flashes dim orange lights.

Apple Does Not recommend that. Please Read.
http://support.apple.com/kb/HT1490
From that article
"Portables with built-in batteries"
Current Apple portable computer batteries are pre-calibrated and do not require the calibration procedure outlined in this article. These computers use batteries that should be replaced only by an Apple Authorized Service Provider.

Apple recommend calibrating the battery when you buy a new Macbook and then every few months, or monthly if it used on mains all the time. This, as Apple says is to keep the battery operating at maximum efficiency. When the battery discharges and shuts the macbook down, it still has reserve power for a good number of hours. There is also a logic board battery to hold various settings.
I rather think I will take Apples advice on using their equipment not yours, but I would be intrigued to discover what is it you know that Apple doesnt about its batteries?

Have an iMac 2008/09 on starting today I have a white screen, an apple icon and a constant rotating sun, nothing else. I've tried turning off and disconnecting and reconnecting the power lead with the same results. Any thoughts? Many thanks Matt

Have a 2008/9 iMac on starting up today I have only a white screen, apple icon and a continuous revolving sun. Have tried turning off and on and disconnecting and reconnecting the power with no affect - any thoughts or advice please. Thanks Matt

If your iMac came w/system DVDs, do the following:
Disconnect all devices from the computer then do the following:
Boot up from your DVD that originally came w/the iMac while holding down the "c" key.
Select the language you wish to use, and then choose "Disk Utility" from the menu bar.
Your HD should appear in a panel on the left hand side of the window which opens. Select it and then click on the "repair disk" button in the right hand section of the window.
Once this process has been completed restart your computer and repair permissions directly from Disk Utility.
If Disk Utility is unable to complete the repair, you will need to use a stronger 3rd party utility like DiskWarrior, Techtool PRO (not Deluxe) or Drive Genius.

My MacBook won't start after iTunes update. I keep getting the spinning wheel. Any suggestions?

While trying to back up my iPhone 4S to iTunes, I received a message that iTunes had to be upgraded. I did the upgrade, but my computer won't start now. I get a white screen with the spinning wheel. (Like the computer is trying to boot). Any fixes?

Please verify you got this screen as well:
I had the same after updating fronm 10.7.1 to 10.7.2 tonight. Not even a re-install of the OS X 10.7 and Combo update to 10.7.2 helped. I think this time Apple messed up big time with the 10.7.2 update and some Mac Books (my case: MacBook 15" Mid 2009 = MacBookPro5,3)
If any Apple Support person reads this: Please get in contact with me. This is highly unusual!!
I think the best thing would be to call AppleCare 1-800-MY-APPLE.

Macbook won't start up, no chime, nothing even with a full battery

I can plug it in, it'll charge, but when i press the power button, nothing shows up on the screen and the only thing that tells me it's on is the fact the light on the bottom right lights up and stays lit. It will accept a disk when it's turned on, but it won't spit it out.
It's a Core solo, so it's one of the first ones so it's got a few years on it. I've done all the steps leading up to "take it in, dummy" but since I won't be able to do that until tomorrow, I'm brainstorming what it could be.

Did you try holding the power button down for 5 seconds with the battery and the AC power both removed?

IPhone 5 won't start or charge or turn on and was not dropped recently and the power button has never worked

My iPhone 5 was not dropped recently however I went to use it and the screen was black, I plugged it in and nothing happened. When you call it it goes right to voicemail. The power button on it has never worked it always turns on when plugged in... Any ideas?

Are you certain that the battery has not run out? Have you kept it plugged into a wall outlet for at least 30 minutes to see if it is just needing to be charged?
If it does not come on after being plugged in for 30 minutes or so, then without a functional Power button you cannot reset it, so you are going to have to try to put it into Recovery mode and restore it:
If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support
You may not even be able to do this since you cannot proactively turn it off, but you can try.

Try Resetting your Mac's PRAM and NVRAM
If that doesn't help, try Resetting the System Management Controller (SMC)
in really disappointed with apple,
Serge... you are aware that you are responsible for backing up your importanta data correct ?

2012 Macbook won't start but fan maxes out

I cam home today after 4 day travelling. The Macbook was turned off while I was away with no power connected. When I tried to start it today the power light flashes (not slow blink) about every 3 seconds and the fan runs full but nothing starts up.
I have done PRAM, SMC reset, disconnected and reconnected the battery, reseated the ram modules. Nothing has worked. What am I missing?

Take a look at this. Specifically look at 3, 4, 7 & 8 and see if any of them can work for you.

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?

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

My i-Pad won't charge after I downloaded some stuff from i-Tunes. I have tried charging through two computers and using the wall socket,, with different cables. I have turned the i-Pad off & on a couple of times but it still won't charge. Any ideas will be gratefully received.

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.

Charger stays green, battery won't charge and MacBook won't start up

My son just gave me his old MacBook. While visiting him it worked fine, stayed charged up a long time. When I got home & plugged in the charger and it stayed green, didn't turn amber. Read the user manual and checked the battery level which is 1 blinking light only. It won't power up (I tried all the troubleshooting tips on pg 54) and the battery is not charging. Does anyone think I just need a new battery or do you think I need a new power cord?
So excited to have my first MacBook and now it won't start! I'm an unhappy camper :-(

I recieved mine in christmas 2009.... know what's wrong???

Macbook won't start

Macbook won't start up. Sounds like disc drive is spinning but screen remains dark as though startup file is not booting.

Did you also try reset of NVRAM/PRAM?
http://support.apple.com/kb/HT1379
When you tried the Command + Opt + P + R keys on restart, held almost
immediately and through the time period it should chime on startup, did
you keep holding those keys down, so as to force it to repeat the chime?
You should do this (if possible to tell) through Three chimes, before you
let those keys go; that would be indicative of a NVRAM/PRAM reset.
Aside from the details and troubleshooting processes in the SMC reset
article from Apple Support, that could shed some light on the issue, if
these were done in their subscribed order before finally trying the SMC.
Have you tried System Management Controller (SMC) reset more than once?
http://support.apple.com/kb/HT3964 {and those other troubleshooting bits}
Depending on which MacBook you have, the details may vary; with some
you could try several items not possible with a later model, such as a hard
reset of the computer (remove battery, hold power button, etc) and other
details I am not going into now... Here's something that worked for this one:
•My MacBook won't boot, no start chime, just DVD spinning sound:
http://www.ifixit.com/Answers/View/6271/My+MacBook+won%27t+boot,+no+start+chime, +just+the+DVD+spinning+sound.
There are some ideas there which may help. At least as far as trouble-
shooting. If you have access to an Apple Store with Genius Bar in the
USA or Canada, you could call ahead for an appointment to have one
of their staff genius tech persons diagnose and troubleshoot this issue.
In other locations, there may be fees charged to accommodate services.
Anyway, I an not certain what to suggest next.
Did you try booting from the Snow Leopard DVD?
Good luck & happy computing!

Macbook won't start or charge unless I disconnect and reconnect the battery connector each time .
