Friends macbook won't boot

My friend got his macbook 2.0GHZ from this guy 6 months ago, now he told me one night it won't boot. It has sign it's working by the indicator while asleep. I am thinking it's the logic board, what else could it be? Can a mac not work if it's HD is full?
I might take a look at it, Ihave places where I can taake it.. Thanks

What has he tried?
Has he tried booting from the install DVD?
Does he get the "bong" sound? when pressing the power button?
Remove the battery and the power cord and then hold the power button down for at least 5 seconds then reinsert battery and power cord
Remove and then reinstall the RAM cards as a last resort. Sometimes this is the cure but not very often.
Always look for the simple stuff first because that is the most probable fault

Mdworker deny mach-lookup. But macbook won't boot in safe mode

I have a common problem, I get theese messages every now and then in console:

I have just boot in safe mode. (holding Shift during boot)
but my macbook won't boot in Safe mode. It just freeses with a grey screen for hours and wont boot.
I tried to leave it overnight to boot, but it didn't.
Please help me make my macbook to boot in SafeMode.
my configuration is the following:
MacBookPro8,1
OSX 10.8.2

There is a bug in fsck_hfs that is affecting a bunch of people. Basically as your comptuer starts in safe mode, it runs a file system check (fsck) against your hard drive, it gets to a certain point and... just sits there. No one knows why outside of apple.
Lots of info here, including a way to get around it by tricking the system to think fsck had been run, though the fsck will not be complete so it is not a good solution.

MacBook won't boot when iPod is connected

I have the same problem as described here :
http://discussions.apple.com/message.jspa?messageID=4112865
My MacBook won't boot if my iPod 5G is connected to the USB port.
If I unplug it, it will boot normally.
Does anyone know what could cause that ?

<When iPod is plugged in at startup, the MacBook does not startup; unplugging iPod lets it startup.
yes, it seems that the kernel is not loading
<After resetting the iPod and BEFORE synching it, there is no problem. Any type of synching seems <to make this problem recur.
only syncing music make the problem occur.
the other syncing works ok
<Even if iPod is connected directly to Mac and it is the only USB device connected, the problem still <occurs.
yes
<The iPod and MacBook work fine if iPod is connected after startup.
Yes
<If the iPod is set to NOT mount to the desktop, the problem with startup does not occur.
Yes, but there are some problems in the boot/halt process.
something like "killing all" fails and unmounting /home fails (45) blabla...
and the stopping process takes very very long, about 2 minutes.
thx robert

My Macbook won't boot up because there isn't enough free space for my start up disk. It's now stuck on a blue screen. How am I meant to delete files to free up space if I can't access the computer?

My Macbook won't boot up because there sin't enough free space to run the startup disk. My Macbook now won't go past the blue screen so exactly how am I meant to be able to delete files if I can't access the computer?

Do you have a bootable backup?
What operating system are you running? If OS X 10.6 or lower, boot from your original OS X DVD or a retail OS X DVD and then delete files as needed. Your goal should be to get to 10% of your disk capacity free.
If you have OS X 10.7 Lion or 10.8 Mountain Lion, you don't have many choices in recovery mode (boot holding the command and r keys down).
If you have a FireWire or Thunderbolt connection, you can try target disk mode with another mac.
If none of those work, perhaps your local Apple store can help with a bootable external drive.

Macbook won't boot up - grey screen only

Hi,
I have a core duo MacBook from summer 2007.
All of a sudden the MacBook won't boot up. The battery is fully charged and AC adapter plugged in (same symptoms if not plugged in). The following occurs upon pressing the power button:
1) Start-up chime sounds
2) Can hear hard drive and fans start up
3) Screen turns grey
4) Nothing happens (screen still grey)
Thoughts? I tried resetting PRAM and PMU with no changes.

I have the same problem, just the grey screen and tried
- resetting PRAM (second chime, so this should be OK)
- Safe Mode (just the same)
and pressing Option (or C) to choose the Mac OS X Install Disc gives me the wonderful cursor which can be moved by moving the mouse. No harddisk and even no Install DVD are displayed on the screen.
Also The Apple Hardware Test (by pressing D) doesn't get further than the, now familiar, grey screen.
I pressed the keys with different keyboards, with the original white keyboard and with the aluminium keyboard.
As I've tried everything, I think there's something seriously wrong. Does anybody have some last tips that I can try?

Macbook won't boot up anymore after trying to reformat

So my White Macbook won't boot up anymore after trying to reformat. While trying to install a fresh copy of Snow Leopard, the Macbook just froze and I had to reset. Now, while trying to boot it up, it hangs at a white screen with a folder with a question mark.
My install disk is still in there, so when I try to boot up while holding C, nothing happens. It either goes to the folder with a question mark or the screen stays white. So after that I tried holding option to go to the drives nothing happens. I just see a white screen and a cursor.
I tried resetting PRAM and tried booting in safe mode and everything but to no avail. Everything results in just a white screen or just a folder with a question mark.
Can I do anything before I have to bring it to the Apple Store? The optical drive should work because before I reformatted it, I could see that the disk was in the drive because the icon was in the upper right.

it hangs at a white screen with a folder with a question mark
Startup your Mac while holding down the Option key. That should prompt the Startup Manager window where you can select the startup disk.
A flashing question mark appears when you start your Mac

MacBook won't boot up power light on

My MacBook won't boot up without the system disk, has Lion with 4 Gb Ram all updates, has a DVD stuck n the drive any suggestions

Have you tried booting into Lion recovery mode? Boot holding the command and R keys down.

MacBook Won't Boot just on AC.

My recent issues are power related.
Won't boot. Reason: Dead battery at 0 mAh.
Won't boot with dead battery even on charge...
When I take out the battery, it won't boot anyways.
I got lucky since I plugged it in when I left it off charge for the night, and went away about 10 minutes, and it boots. Now that won't boot it up... I take out the battery and tried to boot it since I know it's dead. Nothing.
I have 2 MagSafe adapters (One is OEM and is spliced (Charges and fine), and another is not OEM (stupid eBay lied) ) and when I remove the battery to boot just on AC power, nothing. Tried both chargers, both plugs, 2 tips and extension cable, Nothing.
I noticed the light is a dim green when I plug in my OEM charger to my MacBook.
So how can I get it to boot on just AC power? Noone I know has any type of Mac...

If your MacBook won't boot on just the AC adapter, and you are certain the AC adapter is not damaged, then there is a hardware issue with your computer that needs to be repaired.

Oh, shoot! My MacBook won't boot! Silver screen is all I see!

Oh, shoot! My MacBook won't boot! Silver screen is all I see

Try a PRAM reset:
Shut down your Mac.
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 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.
Any unusual noises coming from it?

Macbook won't boot properly.

Macbook won't boot. When turned on, it starts clicking; after a while, I get a gray screen with a blinking folder in the middle that has a question mark on it. After a minute or two, it shuts off.

That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
Put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
Or if you are running 10.7 Lion, boot from the recovery partition (Command +R on boot) and use Disk Utility to repair your OS 10.7 partition.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

Macbook won't boot, black screen, no chime

My macbook won't boot at all. It is a white non unibody one. When you press the power button the screen breifly blinks and a clicking sound is heard but no other sounds or chime or anything. I'm suspecting the worst but thought i'd submit it on here first. Any help is appreciated. Thanks.

Thanks for the reply but it isn't a hard drive issue. I have tested the hard drive in an external enclosure and it's working fine. I even put in another hard drive i have and it wont boot that either. I'm thinking its a logic board issue. Any one know best place to get logic board replacement near london for cheap

MacBook won't boot...not like I've ever seen before.

I have a friend who has a 15" MacBook Pro model from mid-2009. He called today because when he turns on his MacBook it goes right to a blue screen and won't boot. He lives 7 hours away but it just so happens that I'm going there next week and I will stop to check it out, but figured I might ask to see if anyone here knows. So here's the situation.
The MacBook is running Snow Leopard 10.6.4 and it was in sleep mode. When he opened the lid the computer wasn't responding so he did a manual powerdown and when he turns the computer on, it makes the chime but goes directly to a blue screen and after a few seconds the folder with a question mark starts to blink.
I know that the question mark means that the system can't be found meaning either there's a corrupt system file or the hard drive quit, but I've never heard of this appearing on a blue screen, usually it's grey.
His system DVDs are back in his hometown (he is in university) so I couldn't get him to do either a Hardware test or run Disk Utility, but I have a 13" MacBook Pro so I will bring my system DVDs out with me to do diagnosis.
Anyone ever experienced this? I can't find anything like this anywhere. I had him reset the PRAM, the SMC, and also tried to get the thing to boot into Safe Mode and Verbose, but no luck. Holding down the option key during startup brings the blue screen again, but with a cursor.

I meant to post what I found when I got my hands on it, but totally forgot. Here's what happened:
When I got his laptop I booted it into FireWire Target Disk Mode and connected it to my Mac. I opened Disk Utility and and error came up saying the connected hard disk needed to be initialized. I couldn't access the filesystem. I tried running diagnostics via Disk Utility and with fsck in the Terminal, with no luck. I did some searching on Google and found an article explaining how the filesystem can basically become broken when a key file is either overwritten or altered.
The article suggested using DiskWarrior, which I got and ran the program on the corrupted hard drive. It warned me that by doing the diagnostics some files may disappear, as it basically undo's whatever caused the filesystem to die. It only took a minute and just like magic the disk showed up on my desktop.
I backed up all the user files and then wiped and restored the OS and Applications and user files. I couldn't tell if there were user files missing as it wasn't my computer but at least it got fixed! DiskWarrior has now joined my arsenal of fix-it apps.

Macbook won't boot from Hard Drive of Disc Drive!

So I bought a Macbook (Mid-2010) from a friend recently and I can't seem to get it to boot from the hard drive or optical drive. At first I tried booting from the HD it already had and when I didn't have any luck, I went out and bought a new one. It still won't boot. I'll turn it on, it'll chime and will try to load, and then I'll get the "You need to restart your." message. I've tried booting from disc (Leopard & Snow Leopard) and will still get the same message. I have also tried all possible startup key combinations and haven't had any luck. I don't have the original DVD it came with. So was wondering if any of you guys out there have experienced this. I would like to hear your tips before I go to an Apple Store and see if they can get it fixed for me.

"You need to restart your." message
That is referred to as a "kernel panic"...

I don't have the original DVD it came with
You will need those discs. Replacement disc(s) from Apple: You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.
You can check the startup disk using the Disk Utility application located in /Applications/Utilities if you can boot in Safe Mode, but you cannot make repairs without the install disc.

How do I back up my MacBook Pro from an external hard drive if my macbook won't boot up from the white start up screen? HELP!

I went to the Genius Bar a week ago, and the guy helping me there was nice enough to help me save some money by telling me I could replace the bad hard drive my MacBook Pro had by myself. I bought everything I needed (hard drive, screws, external hard drive) and my computer won't boot past the white start up screen. It doesn't even show the Apple sign at the start up screen. How do I back up my computer so I can save all my music, school files, etc.? Could really use someone's advice on what to do! Thanks!

Ok, to be sure I understand what's going on. You were able to boot the Macbook from the existing "damaged" internal drive, and it has been backed up to the internal.
If that is correct, your internal drive is working. Just to be sure, try booting with the R key down. Then run Disk Utility to repair the internal drive. That drive may in fact be useable.
You should be aware that you cannot boot the MBP from a Time Machine back up.
Please post back so I am sure I am understanding the situation.

MacBook won't boot from disc

On Sunday my ten-month-old MacBook froze up and made some nasty clicking noises. I forced a restart, but now it just boots to a white screen and, after a good five minutes or more, eventually displays the blinking, question-mark folder.
I'm quite certain the drive is toast, but what I find more interesting (and in some ways more irritating) is that I can't for the life of me get it to boot from a DVD. I've tried my Leopard disc and the install disc that came with my computer. I hold C while booting, the drive spins for a bit, and eventually it just spits the disc back out. I've also tried holding D with the original install disc to boot the Apple Hardware Test and get the same result. I've tried holding Option to get a list of boot volumes and just get a white screen with a mouse cursor. I've tried resetting the power management unit and zapping the PRAM, as suggested in the "What to do if your Mac won't boot" list, and have noticed no change.
Thoughts? There must be something else I can do.

You may have a bigger problem than just the Hard Drive. Call Apple support or go by an Apple store if your near one and talk to them. You've done everything you can do. It will be up to them now. Be thankful it's still under warranty.
