MacBook turns on but won't boot up

Macbook will turn on, the apple symbol shows on desktop, wheel turns but won't fiish the start up to a full desktop. Any ideas!

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.
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 turns on but won't boot (start)

Purchased macbook in December 2008. Genius bar staff said it needed repair. before handing over the macbook for repair, I tried the following:
HT 3964 (Intel-based macs) resetting the system management controller (did not work)
HT 1455: Starting up in safe mode(did not work)
Turned the macbook over to the genius bar staff on Friday, March 12th. Informed it would be 5 days before it's repaired. Never had any problems with my windows machine. If it weren't for firewire, I'd stay with PC. Details to follow.

Any electronic device can fail at anytime. That's what warranties are for. Did you have AppleCare? I alway advise buying it, especially on a laptop. Tip: You can get an AppleCare plan on eBay for about 1/2 the price of retail.

IMac will turn on, but won't boot unless I wait until the next day

I've searched this forum, but can't seem to pinpoint my problem. I received this iMac for my office last March, and everything worked just fine. Lately, for the past 3-4 months, I can turn it on in the morning and everything runs fine.
I turn it off in the middle of the workday, thinking I won't need to use it for the rest of the day.
Of course, something comes up, and I need to turn it back on. When I press the button to turn it back on, nothing happens. Just a black screen and if it's quiet enough, I can hear the hard drive running.
It won't boot until I come back the next morning, almost as if I'm giving it time to cool off.
Any ideas?

Turn off Energy Saver and use Screen Saver instead. Energy Saver is sensitive to certain non-Apple USB devices and may cause such a problem.

Pavillion dv9580us turns on, but won't boot or POST

I have an HP dv9580us that I bought about 2 years ago. It had been working well until a few days ago. Now when I turn it on the lights come on, the fan turns, but nothing happens. A few seconds later everything turn off, then the lights come back on again, and it just stays like that. No beeps, no blinking lights (they turn on but don't blink), no sounds, the screen completely blank all the time.
So, I think the BIOS is not even making it to POST at all. I already tried re-seating the RAM, took the battery off, took the CD drive off, re-seated the HD, and reset the bios.
Any ideas on what may be the problem? I suspect the motherboard, but on most cases I read about the system does boot or POST.

According to the result of your tests, you arer pretty sure that there is a CPU or Motherboard failure.
Not easy to say which one fails. Maybe both!
If your computer is under warranty, don't hesitate!
You can extract the HDD and make a backup of it before you send the computer.
I would recommend using a USB adapter that can connect your internal hdd (now external!) to the USB of to another computer.
Modern USB adapters for HDD can do SATA and (P)ATA. They are even shipped with an external power supply so that you can power on your hdd.
If your computer is not covered by any warranty, well, that's harder. You could try to extract the CPU and replace it to see if anything goes better.
Or you could just purchase a new computer and transfer your current data to your newer computer.
There are even some tools that allow you to transfer the data AND the system+applications directly to your new computer so that when you power it on for the first time with the transferred configuration, it can boot enough of Windows to detect the new hardware.
I used to use Qualystem ubiboot to do so but now that Qualystem has been acquired it seems that this tool is not available anymore (or with a larger/more expensive package). There was a company from New Zealand that had a similar tool...
Good luck

My macbook turns on but doesn't boot up to log in screen

I was using Ableton and sudenly my Mac just stopped working. I've rebooted, removed power, rest the smc but can't get it to reboot to the log in screen. It turns on but doesn't do anything but show me a white screen.

i'm having the same trouble.. have you had any luck in fixing it? i'm currently in seoul, korea.. so i'm not really sure where i can take it over here. please let me know if you figure anything out with yours

Turns on but won't boot up

Hello everyone, I really need your help and advice on this one. I am really praying that it is not a huge expensive problem, but I have a white macbook that I bought about a year and a half ago. There has been very little problems with it, no random shut downs, a couple of frozen moments which I figured were just incidental, as I would restart and continue on my journey. however, tonight I has updated iTunes because I had just bought a new iPod, and as I was working I got a grey screen saying that my computer needs to shut down. I did as told, figuring that another one of these incidental moments was happening.
Much to my dismay, my computer now turns on, like the screen flicks on and off, I can hear the familiar "eject" sound from the drive, but i do not hear a chime, and the screen continues to remain black. I have left it for about a 1/2 hour thinking it would kick in, but nothing. I tried everything listed on the support page titled "When my macbook won't turn on" icluding resetting the power amanger, and the various other combination of holding keys, but nothing has happened.
What could possibly going on here, and is there anything I can do to fix it. I am from Canada and have no way of getting to an Apple store, the sad thing is, I just went with friends to the states today, and visited an apple store, but as of now there is no way to get back. I am at a loss of what to do. Plz help!!!
Thank you sooo much in advance!

Another thing is I want to put the install CD in to try and boot from a disk but I already have a cd in the drive from before and can't eject it. Any ideas on how to get it out?

HP 8 G2 clearly turns on but won't boot up

I press the power button on my HP 8G2 and it lights up on the screen, but nothing else, then goes black again

Hey @like2drnkbr ,
Welcome to the HP forums.
I understand you're having issues with your HP 8 G2 tablet.
The first things to try would be a hard reset if you have not yet tried it: While the tablet is on, press and hold the power button for 8+ seconds to force shut down. Turn the tablet back on and see if that helps.
If that fails to resolve the issue you can try a recovery from micro-SD storage:
1. Download the update.zip for your device and copy the file to the root directory of an empty micro-SD card (at least 1 GB, FAT 32 format). Do not unzip this file. You can find the update.zip for your device here: HP - Drivers & Downloads.
NOTE: You will need the exact model number to locate the correct package. There are multiple update.zip recovery images available. Ensure you select the correct download for your region. If your tablet does not boot after attempting to update you may need to try both the KitKat and JellyBean images. For information on finding your product or model number click here: Finding Your HP Product Model Number.
2. Fully charge the tablet and then disconnect the power from the device.
3. Power off the device.
If your tablets micro-SD slot is on the side or bottom of your tablet skip to step 5.
4a. Place the tablet on a flat surface, display panel side down, with the release notch towards you.
NOTE: Before positioning the tablet with the display panel facing down, make sure the work surface is clear of any foreign objects. Failure to follow this caution can result in damage to the display panel assembly.
4b. Remove the back cover. Use the release notch to remove the back cover.
4c. Insert the micro-SD memory card into the reader slot.
4d. Reverse the procedure detailed above to install the back cover and continue to step 6.
5. Insert the micro-SD card into the micro-SD card reader.
6. Press and hold the volume up (may also be volume down, my available documentation for this does not specify) button and power button at the same time.
7. When the HP logo appears on the screen, release all the buttons.
8. When the Android system recovery menu appears, use the volume down button to highlight "apply update from external storage".
9. Press the power button to validate "apply update from external storage".
10. Use the volume down button to highlight the software recovery file, update.zip.
11. Press the power button to select the update.zip file and launch the recovery.
NOTE: Wait until the entire recovery process finishes. The device might seem unresponsive at times (multiple reboots and black screens) when it is performing the update.
If this does not resolve the issue please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the following link to get the support number for your region: Phone Assist Worldwide.

Macbook turns on but won't charge.

Ok, so here's my quick story. Iced tea was spilled on part of my macbook about 2 weeks ago. It turned off and wouldn't turn back on. Later that day it turned on for about 30 mins and then turned back off. No noises were made, it turned off quietly. Macbook would not turn on for over a week, battery still showed power. Mac turns back on today, appears to be working normally. My personal charger will not charge the mac, my friends charger also does not work. The light doesn't come on the charger and nothing happens. What is wrong with my mac?
It also will not power my macbook, it doesn't recognize that its plugged in.

Welcome to the forums.
Anytime liquid is spilled on anything electronic. It should be turned off and the battery removed. Never turn it on until you give it a chance to dry out.
It sounds like your MacBooks circuitry has shorted out in the charger section and possibly other areas. It is hard to say without testing on the bench. You will need to have it serviced by Apple or another repair service. Do a search on the web and you will find some that does work cheaper than Apple and will give a quote before repairs are done.

My macbook turn on, but no show imagen

You won't be able to view them via Apple TV, correct. It is not meant for this function, if that's your intended purpose its best to get a DVD player

macbook pro recognizes but won't print with hp desk jet 5550. Help!

Hi, I used the Mac setup instructions, not the PC ones. The printer was automatically recognised in print and scan when I connected it with a USB cable. I accessed the server's web-based page and followed all the instructions, but still no joy. Thanks for the tip about posting. I have just posted in the section you suggested, so let's see what happens. From a quick scan around the apple forums, lost of other people seem to having precisely the same problem (and not just with HP printers!), but unfortunately, no-one seems to be offering a solution! And trying to get through to the apple online support is a complete waste of time. They've been 'not available' for two days now. Christmas/New Year shutdown, I suppose. Thanks for all your help, though!

Hi Eslam El-Gammal,
Welcome to the Apple Support Communities!
I understand that after resetting your iPhone, you are being prompted for Apple ID information that is not yours. This can happen if an iPhone is restored without turning off the Find My Phone feature. For more information on this, please refer to the attached article.

IMac with bootcamp and parallel boots into windows 7 but won't boot into Mac OS lion?

Hi,
Thanks for your suggestion. Actually that was not the problem, because I had the Mcintosh drive set as my boot drive. The answer was that my Lion Os got somehow corrupted and I had to reinstalll Lion. This was all after I discussed the situation with the Apple Support people.

MacBook Pro Turns On, But Will Not Boot

I recently have had trouble with my MacBook Pro (2.4GHZ Duo Core purchased in late '07). Last night before I went to bed I put my computer to sleep after normal usage of my computer. I did not update anything such as firmware or progams in the past few days. I had it connected to a WD external drive and an external monitor as I have for months. When I went to wake up the computer this morning it would nothing appeared on the screen as it normally does. I waited and tried different things, but no luck. After a minute or two, I just turned it off by holding the power button down. After a moment or so, I turned it back on. The cd-rom drive spun up, but the computer did not post (chime), hard drive seemed not to be active, and nothing appeared on either the external display or the internal LCD. I then turned off the computer again. I disconnected everything, removed the battery for a few minutes and then tried to start it again. The same result appeared each time: cd-rom spins up, no hard drive activity, no display.
I tried various things that was suggested in the Apple Support area such as resetting the PRAM & SMC, as well as trying to get it to boot in safe mode and entering the BIOS. Nothing. Before I take it into the Apple store to have it looked at since it is very far away, I was wondering if anyone had any input on what could be wrong and if I am able to fix it myself. Thank you.

It's possible that you have the NVIDIA problem:
http://support.apple.com/kb/TS2377
Not really sure why it won't boot at all. People have reported suddenly getting no video at all, but I think they usually do get the startup chime.
Probably the best bet is to make the trek to the Apple Store, as this sounds very much like a hardware problem. They should be able to test specifically for the NVIDIA problem.
Good luck!

MacBook Pro HD issues; won't boot to any drive; need to recover data

*Apologies in advance for the lengthy post. I just want to be sure I include as much detail as possible. Thanks in advance for reading all of this and offering any thoughts and suggestions.
I have a 13-inch late 2011 MacBook Pro running OS 10.7.
The computer recently began booting slower and slower until finally one day it did nothing but show the gray boot screen with the apple and a spinning circle and/or progress bar at the bottom. It won't do anything else. I assume it's the HD; no surprise there. What's killing me is that no matter what I do, I can't boot to any disk, internal or external, can't mount it in target disk mode, and can't repair it or recover data, which is a first for me with any HD. However, the computer still clearly sees the drive, and the drive sounds and runs normally (meaning no clicks; appropriate amount of whirs and such).
What I've done so far:
Reset PRAM — no help
Reset SMC — no help
Boot in Safe Mode — same result as regular boot: gray logo screen with spinning wheel
Disk Utility message:
Verify Disk — "Error: This disk nees to be repaired. Click Repair Disk."
Repair Disk — gets as far as "Checking catalog file" then shows "Keys out of order". Next is "Rebuilding catalog B-tree." Then "The volume Macintosh HD could not be repaired."
fsck — same as Disk Utility: "Keys out of order (4, 22016)", "Rebuilding catalog B-tree", then "The volume Macintosh HD could not be repaired." FILE SYSTEM WAS MODIFIED." ...over and over again
If I hold Option while starting the computer, it gives me only two drives to boot from, regardless of any other external HDs or flash drives I have attached: Macintosh HD (internal), and Recovery HD (internal partition). If I choose Macintosh HD, it's hit or miss whether it prompts the Disk Utility screen or just gray-screens forever. If I choose Recovery HD, it successfully runs Disk Utility every time. Here's the thing, though — if I attach an external HD, it doesn't see it during the initial Option-startup. However, from Disk Utility I'm able to select a startup disk from the menu to restart into. It sees the externals in there every time and lets me select them as startup disks, but upon restart it returns to the gray Apple logo screen with spinning wheel and/or progress bar at bottom. Sometimes it also sees the internal Macintosh HD here, but selecting that is useless. I can't actually boot from any disk, internal or external, running full OS or even just recovery software.
I've tried using TechTool Pro 8's edisk and ProToGo bootable drives, but again, the MacBook only sees them from Disk Utility only (not on Option-start), and I can select them, but it doesn't actually boot to them; it reverts back to gray screen.
I've installed a full version of OS 10.10.2 on an external hard drive, complete with DiskWarrior 4 on it, but same problem as above — it sees it in the "Select Startup Disk" menu, but not in the initial Option-start or successful reboot.
I've tried booting from a DiskWarrior 4 DVD using C-startup. It recognizes and spins the DVD from the get-go. Eventually it boots to it (after about 20 minutes or so of reading the DVD). I'm able to launch DiskWarrior 4 and start a rebuild. However, it goes all the way through "Step 6: Constructing optimized replacement directory... Overlapped files detected: 7 ...Step 7: Finishing construction ...Step 8: Reading from disc, one moment please..." and then the computer kernel panicked. This happened several times. I reset the PRAM again, then retried DiskWarrior DVD boot, this avoided a kernel panic and it got as far as "Comparing directories... Step 9: Recording any file or folder differences; 3,449,089,956 tests..." and then DiskWarrior and the computer both freeze and I have to force shutdown.
The drive will not mount to another laptop in Target Disk Mode.
Disk Arbitrator immediately sees the the faulty laptop HD, but won't let me mount or unmount it. It's just there, grayed out.
Data Rescue 4 is able to see the faulty laptop HD through Target Disk Mode, even though the drive itself will not mount to my desktop. I am able to scan the drive using DR4, and start a data recovery process. However, DR4 is dumping all recovered data into "User Defined" ai (Adobe Illustrator) files, which makes absolutely no sense at all. What's more, the files aren't able to be opened by any program. Even files that it hasn't recovered into ai files, like txt and mpegs, cannot be opened. I've tried recovering from both the drive itself and from a clone of the drive (made through DR4), with the same result each time.
So, all of that said, I guess my first question is what the **** is going on? The drive mechanically is functioning fine, but there seems to be an issue with its readability (and the directory/files?).
What's more, why won't this laptop mount ANY drive? I should be able to Option-boot into any drive, especially if the USB ports, drives, and OS's are all fully functional, right? Is there any workaround I'm missing? Even if the internal drive and data are just screwed, what's causing a total lack of mounting or booting of any drive, internal or external?

Holy crap, I got it to work.
Essentially, I just waited until DiskWarrior reached Step 9 and told it to skip the step before it had a chance to freeze. It skipped successfully, moved on, rebuilt and replaced the faulty directory files.
So far the computer is booting like normal, I can log in, and I'm currently copying all of the data to an external as I type this.
I still have no idea why the computer wouldn't mount or boot to any drive, but I guess I'll deal with that later.
