Macbook and loss of power
I lost power with my Macbook, and after rebooting, my email accounts were gone!!
For anyone experiencing the same issues, I wanted to post a supplementary and final post on this issue.
Several days in with the 253 cycle battery, I noted the following:
1) The iBook breezed along with the power connected. Essentially it was back to its old self.
2) Unplugged, it developed occasional freeze tendencies when the power dipped below 40-50%.
3) The iBook passed every test I threw at it. I could find nothing obvious in any of the logs to suggest a hardware problem (other than a kaput battery).
Almost certainly its probably a power issue although I suspect the HD may not have years of useful life. I swithered about replacing the battery with a new Apple battery, a NewerTech battery or another 3rd party replacement battery. After some thought, we bit the bullet and retired the iBook and we now have a white unibody MacBook. Depending on its saleability, the iBook may well be destined to live on as an entertainment device/traveling Mac as it is still a solid performer for lighter tasks.
Upshot: when your iBook starts behaving weirdly, take a look at the battery health.
Thanks
Gareth

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! -

I have a MacBook pro that has power issues and will not start but the hardrive is fine. I do not want to lose all of my files so I was wondering if it's possible to transfer my hardrive from a older Macbook pro to a new one if I were to purchase a new one? Also, the software is not updated as the computer hasn't worked for about 2 months.
Also, if it is possible to transfer the hardrive, would my iTunes music transfer as well? It is not saved in the cloud.
Thanks for your help, it is much appreciated.You computer is probably perfectly repairable, but if you want a new one anyway, it is perfectly possible to transfer the data from the faulty one.
But it would be a mistake to simply put the old HD in the new computer.
These are the steps:
Remove Hard drive from faulty computer. (very easy on Unibody MBPs, do-able but not so easy on older MBPs)
Put it in a cheap enclosure
Connect it the new computer
Boot up new computer.
If the new computer has never been run before the Setup Assistant will ask if you want to import your apps, data, settings etc from either another mac, another HD connected to the Mac or a Time Machine back up.
Obviously chose the second option (another HD connected to this Mac) and follow prompts.
If the new computer has already been run (so Setup Assistant doesn't run when you boot it up), you will need to use Migration Assistant...or run the installer again so that Setup Assistant runs again.

Macbook and Macbook Pro Power Adapters
Is it safe to use a Macbook Pro power adapter in a Macbook and vice versa?
I have just noticed that the MBP's adapter is 85 watts and the MB's is 60 watts. I hadn't realised they were different.
My wife and I share each others adapters all the time (she has a Macbook). Will this be damaging either of the laptops?Shouldn't cause any problems. The main issue will be that the 60w adapter won't provide enough juice to both charge the MBP battery and run it if there is much of a load so I'd avoid using the 60w on the MBP for anything other than charging the battery whilst not using the machine - sudden power shortage could be painful for the machine.
Best of luck. -

my macbook air keeps coming up with a message" are u sure u want to shut down..etc" after which it switches off by itself. now it's off and will not power on altogether. any suggestions?
Does it power on if you plug in the charger?
But to be honest I see in your description it says 'Late 2011' so there is a good chance you have warranty right, I would take it to Apple store and let them sort it out -
Can a .mov file be recovered if the record was accidentally shut down from loss of power? i was recording from the AJA Pro Ki when we lost power, the file is there but it wont play and comes up with the message, "The document “SC1ATK63.mov” could not be opened. The movie is not in a format that QuickTime Player understands."
Hi,
Troubleshooting a start up script can be difficult. There are some third party programs that also keep logs of start up programs, however for Firefox this may be different.
Is Firefox a startup program? [http://www.winxptutor.com/msinfo32.htm]
Its also possible to check the Web developer tools for any scripts in a page: [https://developer.mozilla.org/en-US/docs/Tools/Debugger]
In the control panel there is also Administrative tools to view event logs, but this may be something a local technician can walk you through. -
My 13.3" macbook pro will not power up.The battery indicator light does not come on.The Mag safe charging light flickers green and red dimly.I had a cell phone connected to the USB port.
This didn't work for me, so I did a bit of searching and TONS of pages later in google, I found an answer. Here are the steps for people who also were in my situation:
1. Take off bottom case
2. Unplug battery - blurry image here: http://i.ytimg.com/vi/03cC79r5Dx4/0.jpg
3. Press and hold power button for 5 seconds
4. Plug a charger in, and it should start booting up
5. After shutting down again, reconnect the battery and close the case up
6. It works! (hopefully, if you guys had the same situation I did) -
Same power adapter for Macbook and Macbook Pro?
We have a new Macbook and Macbook Pro in the house and I was wondering if the power adapters were interchangeable. I noticed in the store there are two different adapters for sale, but the ones we have appear to be the same or similar. I feel almost certain we can use them with either computer.
Thanks for your help.The 85 W MBP adapter can be used with both, the MB will only draw what it needs. The lower wattage MB adapter will not simultaneously power the MBP and charge its battery, but it won't do any harm.
Hope this helps... -
Power adapters for MacBook and MacBook Pro
Are Apple power adapter universal for MacBooks and MacBook Pro's manufactured over the past few years. I would like order a spare power adapter and I own three laptops all which have been purchased in the past three years. I have two MacBooks and one MacBook Pro.
Not sure what you are asking. The AC adaptors for MBs and MBPs are not the same. The former is rated at 65 watts and the latte is rated at 85 watts. The latter could be used with a MB or a MBP, but the former could not be used with a MBP. Both adaptors have the same MagSafe connector. They would work on any appropriate Intel model since 2006.

I purchased a World Travel adapter kit a few weeks ago, because I'll need to use my MacBook in Italy. Is the World Travel adapter kit all I need to SAFELY charge my MacBook and iPod with their respective power adapters while in Italy, or am I missing something?
MacBook Mac OS X (10.4.9) Black w/ 2GHz Processor, 1 GB RAM, 120 GB Hard DriveAs Mort said, no need for more. It's just a matter of having the right prongs, since the bricks themselves are meant to operate from 100 to 240 volts. To my knowledge, no country on earth uses higher (or lower) voltage...

Why does my music sound so differant on seperate devices ?.
same song differs in quality between ipod classic , nano , macbook and ipad.
do the devices have power output ratings if so is one more powerful than the other ?.
same song , same headphones all downloaded from the same sourceDoesn't anybody have any ideas why diagnostics say "no universal serial bus controller found" and yet founds connected device information just fine?
IPod and iPhone appears in itunes and device manager with no problem, but syncing stops with error everytime.
Do you think that this would be an issue with: ITunes, Windows 8 or Asus Maximus V Formula motherboard?
Am I right, that diagnostics should find universal serial bus controller even though there was nothing attach to it?
Am I alone with this problem?
I have also iPod 4gb and iPod 8gb, which shows in itunes, but I'm affraid to sync them if those stops same way. -
Macbook is out of power and will not charge. Charger is fine as is working on fathers and sisters MacBooks - what should I do?
Does the connecter seem to be making good contact? Is yours a model with a replaceable batttery or not?
Might have to visit an Apple Retail store genius bar, or authorized repair and have them check out the battery to see if it has failed. -
