Help - my MacBook wont start?
The led is on but the machine wont start up?
I have tryed to hold the powerbutton down and violet close, but when I try to start up, the same problem appears :-(
I think you'll need to tell us a bit more: MacBook model, and what exactly happens.
For example, you're posting here under "MacBook Air" but refer to an LED... which the MBA doesn't have.
After holding down the Power button for a while (which shuts down the Mac no matter what), is that LED still on?
When you attempt to start it, can you hear the start-up gong?
Does the screen remain dark, or do you get to see at least a grey screen? If so, how far does it go before it stalls?

My macbook wont start. it just comes to a black screen that sais no bootable device.
Ok then either the drive has failed or the cable from the drive to the logic board has failed or the drive is so corrupted that the computer doesn't see the OS on it.
Boot the computer from the original install DVD that came with your system. If your system is new and came with Lion then at startup hold down the Command+r keys and that will either boot you to the built in Recovery HD or to the internet recovery system. From either of those you can check the drive for error and or see if the computer even knows there is a drive in the system. -

how do i fix this?Not saying you have to reinstall...
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, 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. (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. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."

There indeed may be something wrong with it, but we're just other users here... have you tried Apple Hardware Test? (Holding the d key down while booting from the Install Disc). -
Macbook wont start and makes ticking noise
The subject line says it all. My macbook wont start and it makes clicking noises from inside the case, kind of like a watch. The display turns on and the chime goes when it starts, but the screen stays white and nothing happens.
You can run diagnostics from the OSX disc. Insert disc one and while it is booting hold down the d key. This should take you into diagnostics.
You might also try to reset PRAM AND PMU first.

My MacBook wont start: Asking me to insert booth disc
I was trying to set up my mac to back up to a new Seagate External Hard Disk and during the process, i was asked to restart the macbook. When i tried to restart, i then got a black screen: asking that i insert a booth disc? I am so lost and it wont start. I also had not even backed it up. I am scared of losing my data. Can anyone help
Hi Guys Forgive my lack of details....this is actually my first time on this forum and i am not that much of a computer guru. My system is a Mac Book Pro, bought it in 2009 and was running on OS X.
The seagate external hard disc is a 1TB "Free Agent GoFlex". It comes with it's soft ware that installs when connected for the first time. So when i connected it, it installed and then gave me the option of restarting the Mac right away or later on. So i chose to restart right away......One thing i remember is that i did not disconnect it from the Mac while restarting. So this message then comes up on a black screen "No bootable device.....insert boot disc and press any key". I was at a loss as to what to do....so i came online and posted the earlier message.
I have disconnected the Hard disc, but still the same message comes up each time i attempt to start it.
I would really appreciate any info that could help me resolve what ever the problem is.
Thanks -
Macbook wont start -- have to reset SMC and PRAM
Hi,
Sometimes, when I try to switch on the laptop, it wont start.. Nothing happens.
After reseting the PRAM and SMC, it comes up. But the issue is for the last 3days, I have to do this everytime.
Can you help me out on this one? Sometimes, I had to wait for like 5-7 minutes and then I have to switch on the laptop after reseting.
I dont know, whether it is affecting my laptop h/w.
I bought this 5months ago. its Macbook Air Mid 2013 model.Hello there, tcpipv6.
The following Knowledge Base article offers up a good number of steps to try for troubleshooting issues with your MacBook not turning on:
Troubleshooting: My computer won't turn on
http://support.apple.com/kb/TS1367
If your computer won't turn on, try each of these steps:
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.

If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).

White Unibody Macbook wont start...
Hey there.
So before ppl tell me to do more rearch or try resetting the smc or pram or whatever else they normally say to do... I've already tried all of it...
been looking for the past 6 months and posting here is my last option...
My MacBook just wont start.
I hit the power button.. the little indicator light on the front comes on. The fun runs at a high speed and theb I hear the hardware disc and the fun just shot off.
That's it.. nothing on the screen..
and it'll do this over and over and over again..
Sometimes after 10 minutes it'll start..
Other times more than 2 days and nothing..
It just wont turn on...
Its been 2 days and no results.
I can't put my MacBook to sleep or close the lid because THIS is what happens to it..
I can't even shut it down or restart it because this happens to it...
I'm at the end of my rope..
All my university crap is on here..
thankfully I atleast backed up my notes online..
but without this computer I'm screwed...
Help?If you have already tried the steps you say you have above and the issue is still present, you have a hardware issue. Contact Apple using www.apple.com/support/contact if you are in a country that supports it or call the appropriate phone number on this page. Alternatively carry the MacBook in to an Apple retail store or service provider to ask for an estimate.
Best of luck. -
Im having trouble starting my powerbook. When I turn on the computer first I see a folder with the question mark, then a grey screen with a black square in the middle saying that i need to restart my computer. I know its a Kernel panic. I tried to use the disk utility to repair it. It repairs but it still wont start up. I tried re-installing the software and it cant find a drive to install it. I try to turn it on in safe mode and a bunch of information about the kernel appears and at the end it says "panic: We are hanging here. . ." So i dont know what to do. Can someone help me please. Thank you so much.
It could be your ram. Inspect that is in place properly.
