Battery full - Mac wont start. Heeeelp!

I just purchased my MacBook a month ago and I love it. Now Im having a problem...
I just had this problem today. The battery is full but my Mac wont start. But when I connect it to the power adaptor - it will start. Should I change something on the Energy saver option?
I've tried to remove the battery and placed it back, but the problem is still the same. I need your help please... thanks in advance.

Yup, looks like you've joined the Macbook Shutdown/won't boot club. Mine did the same after the random shutdown problem. I reset the PMU and NVRAM and PRAM and suddenly it wouldn't boot or operate on battery. Let me guess, it works fine on the adapter, but when you pull the plug it immediately shuts down, right? Even though the battery is fully charged? I'm also from DK. Did you buy yours at Humac? Mine is being repaired as we speak, well actually it's waiting for parts (new logic board and battery) but it's taking forever. Turned it in on july 25th and it is still waiting for parts. My advice is to demand a new one, don't hand it in for repair, because I seriously don't think they know what is wrong yet. What week is your Mac(Check the serial-number and post it)?
I've heard that a lot of people got the LB replaced, but soon after the problems started again.

HT4904 I need to repair my start up disc so I have to start up from installation disc. In doing so, my computer restarts, I hear the mac sound, then a grey screen and then turns off and goes on in this cycle endlessly. Why can't I restart from disc?

Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple
logo appears.
5. Wait for installer to finish loading.

My Mac wont start! what can i do?

My Mac wont start! After i restarted it for a update it just crash when i try to start it what can i do?

What and why aren't people doing something simple that has worked for the last 10 yrs:
Clone your system before you ever apply updates
Always have a working bootable backup (or two)
Keep the prior version on the shelf
Keep the combo updates around also.
It is not hard or rocket science.
There is no mechanism to undo rollback or restore check points. No utility to sandbox updates and revert as they sometimes go wrong. Things that are overdue.
MicroMat made having an "eDrive" partition s sinch to do and was its own recovery/emergency boot partition.
Carbon Copy Cloner has been around since 10.2.2, and later SuperDuper and others, Clone X etc.
A clean install is simple. Keeping your emergency boot drive for maintenance updated but with just Apple OS and essential drivers.
Use Safe Boot beforehand. People used AppleJack before updates or at first freeze or sign of trouble.
If you have more than enough room for TimeMachine, then a couple options:
Set aside 35GB is more than enough for emergency boot maintenance (Lion Recovery is nice but doesn't have everything your toolbox might want or need)...
Set up a partition large enough for your working system, again 40-80GB should be enough, you won't clone everything as you can leave your home account folders for TimeMachine if you want (but do want to copy your home Llibrary ~/Library). perfect job for Carbon Copy Cloner.
Setting up an external boot drive is 101 along with TimeMachine.
Not a good idea to have all your eggs in one basket two or more backup drives is better but...
TimeMachine - 350% your total files and changes needed to have file history archived,
Emergency OS
Clone OS
I prefer a 1.5TB minimum.would do fine for most.

orshikhfromsc,
boot from the Mac OS X Install DVD that originally came in the box with your MacBook Pro (by holding down the C key as it starts up). When the desktop appears, select Disk Utility from the Utilities menu and erase your internal disk. After it’s been erased, reformat it. After it’s been reformatted, exit Disk Utility and reïnstall the version of Mac OS X from that DVD onto your internal disk. After that version of Mac OS X has been reïnstalled, boot from your internal disk and run Software Update to get it up-to-date within that version; that should allow you to redownload and reïnstall Mavericks, if desired. If Mavericks is reïnstalled, run Software Update again to get it up to date.
If you no longer have the two grey installation DVDs, you can purchase a replacement set from either Apple or iFixit.

What do I do if my IPad wont turn on completely and what I mean by that I see the Apple logo and I think that it is turning on and then after a while i see the loading symbol which means that it isn't frozen and then all of a sudden it shows the apple log

after a while i see the loading symbol which means that it isn't frozen and then all of a sudden it shows the apple logo once more and it repeats the above

Try this first.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
If that doesn't work, try restoring the iOS software.

If that doesn't work, try this.

Hi, I have a late 2011 MacBook Pro but cant get the mirroring function to work with Apple TV. I've got the most recent Software 10.7.5 but cant see the mirroring icon or turn this on. I'm able to mirror from my Ipad but not my Mac, any thoughts?

Welcome to the Apple Support Communities
AirPlay Mirroring is supported on your Mac, but it needs OS X Mountain Lion (10.8). See > http://support.apple.com/kb/HT5404
You have two possibilities:
1. Make a backup, open App Store and purchase Mountain Lion to upgrade to this OS X. Then, you will find the AirPlay Mirroring icon at the top right of the display, on the menu bar, or on System Preferences > Displays.
2. Keep OS X Lion and use AirParrot > http://www.airparrot.com
Both options work properly, but I recommend AirPlay Mirroring as it doesn't need a third-party program

My iMac turns on the start up chime sounds, you see the apple icon on the screen and then it just shuts off. Any ideas?

Do these two resets:
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
The 5 second timing is important to a successful reset.
PRAM RESET
Zap the PRAM
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.

My 5 year old Mac book won't turn on. It seems to be holding a charge. In the past 3 months I've replaced the power source, battery, & had a full diagnostic run on it.

Tanks dominic23, do you think that the dead battery can affect the macbook performance? I do alot of video work, and since the battery died i cannot do a smooth preview of my videos in premiere cs6, seems like a memory problem but it worked fine before the battery issue.

when i turn on my computer it stays on the grey screen and then turns off by itself. How can I fix that?

Hi , and a warm welcome to the forums!
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & clear caches.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
Hold alt or option key at bootup, do asny boot choices show up?

20" imac won't start up-flashes between blank grey screen and black screen

20" imac
2GHz Intel Core 2 Duo
Was running system 10.5.8 just fine. Worked great.
But then I wanted to give the imac to a relative. And so, I tried to boot from the original grey mac install dvd to wipe the hardrive and set the imac back to factory specs.
But it wouldn't boot off the dvd. All It would do at restart was to flash slowly back and forth between blank grey screen and black screen. So, I tried the Leopard update dvd. Same results. So I zapped the pram and tried again. Same results.
If I just pushed the start button tho.. the imac would start right up and run fine. However, I didn't want to give it to someone else with all our information on it.
I finally restarted it and held the "T" key to turn it into a giant firewire drive, hooked it up to our other 20" imac, and used the disk utility from the second imac to erase the drive of the first imac. Then I inserted the grey install dvd into the second imac and selected the drive of the first imac and ran the install process.
Now, the first imac won't start up at all. Just a continual grey screen for a bit, than a couple of buzz sounds in the machine and then the black screen... than back again.
It ran great before I erased the drive and re-installed OS 10.5
What's wrong? How do I get the machine to either boot off the install cd?

So, I've figured out a little more on the first machine. It's a 20" 2.6 GHz Intel Core 2 Duo running 10.5.8.
It ran great. But, I wanted to erase the hard drive and reinstall the OS system before giving it to a relative.
I found that although the optical drive would read and write to normal cds and dvds, the machine would NOT boot from the grey start-up disks I had on hand. ( I have two imacs, and I tried both sets of dvds without success.)
I zapped the PRAM, and used disk utilities via firewire connection from my other 20" imac to check the hardrive and make repairs. Disk Utilities couldn't find any problems. So, using disk utilities from the other imac, I erased the first imac's harddrive and then used the install dvds on the second imac to install the original OS to the hard drive of the first imac.
(looking on the hard drive of the first imac, I can see all the contents)
However, the first machine will not start up. It just switches from grey....to black..... then grey..... and then black again.... over and over
Why won't it boot from the newly installed OS on it's own hard drive?
And Why won't it boot from the original install dvds?
How can I get it to start up again?

My mac shows a grey screen and spinning gear and nothing else. please help! i want my mac to work again :/

My mac needed new updates and after clickign update it soon told me there was an error and it froze. I then let it sit fo about 15 minutes adn nothign changed so I restarted it and ever since then all my computer will show is the grey screen and a spinning gear :/ can anyone help me with this problem?

I had the same issue, and I had recently backed-up my files (mostly because the mac was acting wonky before this even happened), so I did an erase and install. Then I ran through all the software upgrades and installed all of them. When I did a required restart (for the Mac OS X 10.4.11 update) it went BACK to grey screen with spinning ball. Talk about frustrating!
I think there is something weird going on with the iTunes update and the Mac OS X 10.4.11 update. But one can't be used without the other. So I'm not sure how to update everything safely and get an up to date system, without having all the problems I had before. So now I'm using Mac OS X 10.4.7 so I can have a stable system to do my work, but I can't run iTunes 7.0. I'm too scared to update OS b/c I can't waste another day re-installing everything (for like the third time).
I'm a pretty new Mac user (year and half) so this may sound really dumb, but any suggestions would be very welcomed. I may start a new thread instead of hijacking this one...

Start up problem-can't get past Apple grey screen and spinning gear

Upon trying to start up my laptop, got nothing but the apple logo, grey screen and spinning gear. I tried several things to resolve the problem on my own (hardware test said it could not verify the disk/could not start up from the OS X install disk/reset the power mgmt. unit/disconnected all peripherals)and finally went to the Apple store. Genius bar said they were able to start up from their hard drive and suggested that I buy an external hard drive, go home, start up again and back up all files. I bought a My Book. Got home and same thing happened: Apple logo and spinning gear. I am an Apple user of 18 years, but have not had to do much in the way of diagnostics. Have tried fsck routine today that I found on another posting here today. If the Genius guy got it going, I assumed that I could too. I was wrong. Any advice would be appreciated. It looks like this is the end of the road for my Powerbook, but I'd like a shot at recovering data.

Hi Debbie/Gregg -
I may have missed something but can't you just put a new hard drive in your laptops? You may not be able to recover your data but it doesn't mean the end for your computer. The same thing happened to my TiBook and I put a new 120Gig hard drive in and it's had a new lease of life.
I bought a new internal hard drive along with an external enclosure and connected it up to my computer and from there cloned it. Then I transferred the external into the TiBook and put the old drive into the external and I use that as an external now. I realise your hard drives are dead but you could use another computer to so the same thing and just install the OS on it.
I bought this -

Then followed the instructions here -
http://www.ifixit.com/Guide/Mac/PowerBook-G4-Ti-DVI/HD-Replacement/33/6/
Once your new hard drive is installed you may be able to try and repair the old one in the external enclosure?
