Macbook pro wont start. grey screen then shuts off

I have been having some problems with my macbook when my battery would die and i would plug it in and try to turn it back on it would take forever to start back up. Sometimes i woudl have to unplug, take out the battery then put them back in and zap the pram and it would start. Then today it just started taking forever to restart so i shut it down and tried to restart now it starts goes to the grey screen and the little thing starts spinning and then about 5 sedc later it shuts itself down.
PLEASE HELP

If the Apple Hardware test does not bring up any problems with the hardware, I would advise doing an archive and install before you zero out the drive and erase all of the data on it.
Some things to keep in mind:
If your computer shuts down while booted to the install disk (either the AHT or the installer) you're looking at a hardware problem.
If you need to erase and install or send it in for repair of a hardware problem, you will need to back up any data you do not want to lose before doing so. If you are unable to do backups, an apple store or authorized service provider can do data retrieval for you. Bear in mind this is an optional service and you would be charged a fee for data retrieval.

Torch Wont Start, loads partway then shuts off or resets.

My Torch 9800 was recently went for a swim in rainwater. At first I didn't realize the phone was water damaged, and thought it has just randomly turned off, so I took the battery out, put it back it, and then it started making a static sound. So I immediately removed the battery and put the phone in rice. Unfortunitely got my time lines mixed up and tried to put the battery back in too soon and again the phone started making a static sound. So I took the battery back out, and put it back in rice worried that I'd fryed all the circuits. However, 48 hours later I put the battery back in and the loading screen came up, but when it went to the rogers screen pre-my wallpaper the phone reset and started to load again, then it shut off. Everytime I do a battery pull the led light comes on for a couple seconds, and then it shuts off and nothing happens. So I took the sim card out, and tried the batter again and the phone started to load then shut off.
I've found that If I leave the battery out for a while the phone will start to load, but either gets stuck at the 2/3 mark and will freeze there, or it'll shut off. Today I tried putting the battery back in, and the phone loaded to my home-screen, but then froze and shut off.
If I plug my phone into my computer through the USB the phone connects for a second, and then disconnects. I've tried with both the battery in and out.
I've also tried re-installing the OS through the loader app as mentioned (http://crackberry.com/blackberry-101-lecture-12-how-reload-operating-system-nuked-blackberry), and through a force connect with desktop manager (by hitting update button when desktop manager tries to connect with my phone when I first plug it in to my computer, before it resets and disconnects). Both times the phone starts to load the OS, but when it comes to re-initialize the phone, it'll disconnect, then reconnect, but then after 4-5 seconds dissconnect again, and so I get the "Application Loader was unable to connect with your device" error while the loader is trying to recconect to JVM...
Is there any hope for my phone? I love my torch and was realllly hoping to hold out until Blackberry releases their new phones in the new year.
I think I might try soaking the phone in 99% isopropanol in hopes in might be just some mineral build up from the rain water.
But I'd really appreciate any suggestions anyone has to help me try and get my phone working again.
Thank you.

Hello...and apologies for the delayed reply!
Hopefully you already have resolved this...but just in case...
Applying power to your BB between it getting wet and doing the proper process (including the maximum waiting time) reduces the chances of success. Further, the only thing predictable about moisture intrusion into a BB (indeed, any electronic device) is that the results will be unpredictable. I've seen some come back up right away and be fine. I've seen others never work at all. I've seen still others run for a bit, and then die later. And every thing in between.
Good luck!

My MacBook Pro shows a grey screen at start-up how do I fix this problem?

My MacBook Pro shows a grey screen when I try to login and won't go onto my homepage. Why has this happened and how do I fix it?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

What do i do if my ipod touch keeps going to the charge screen, then to the apple screen, then shuts off?, what do i do if my ipod touch keeps going to the charge screen, then to the apple screen, then shuts off?

what do i do if my ipod touch keeps turning on, going to the charge screen, then going to the apple screen, then shutting off?

If it is still charging using the adapter, let it stay there for at least 15min, then connect again, if necessary use recovery mode. iOS: Unable to update or restore
If still not luck, and the battery still shows the red charging icon, you might need a new battery.

MacBook Pro has a grey screen with circle and slash and will not start up or start into safe mode.

MacBook Pro has started to get a grey screen with circle and slash and will not start up or start into safe mode. This happened once previously, however, it allowed a safe mode reboot and then worked for a week or so. While utilzing the machine, it started with the spinning beach ball for about 5 minutes, went into a shut down mode and then rebooted and came back up with the grey screen with a circle and slash after a few minutes. For the past three days it has been stuck and will not allow it to boot into safe mode. Any idea or suggestions?

Try starting the MBP with the OPTION key down. If you see two HDD icons, select the recovery Icon. From the 4 option menu, select Disk Utility. Select Disk Utility>First Aid and run Verify and Repair.
If you cannot get into the recovery partition, make an appointment at an Apple store genius bar.
Ciao.

MacBook Pro goes grey screen, then shuts down randomly

My MacBook Pro (just purchased 3 months ago, not retina) shuts down unexpectedly. The screen goes grey, then it just shuts down after a few minutes. Anyone else have this problem? Any ideas how to fix?

You need to reset the SMC on your Macbook.
* Shutdown your MacBook Pro
* Connect the power adapter to your Mac
* On the MacBook's keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
* Release all keys and the power button at the same time
* Boot your Mac as usual

I found this link.
http://techtips.salon.com/create-mac-recovery-disc-2797.html
It explains that you must install Snow Leopard to an external drive or LARGE USB Thumb drive, at least 16GBs in size, and then boot the system from that external media and run disk utilities from there on the internal drive.
So if you have a LARGE USB thumb drive or a external hard drive you can continue this to see if the internal hard drive has failed. If not you could buy one tomorrow or take the system into a Apple repair center.
Wishing you the best of luck.

My macbook pro 2011 shows grey screen with apple logo and want start

i was just using my macbook pro and it freezed for a while not responding and i turned it off by pressing the power button. afterwards, i turn it on and it shows a grey screen with apple logo but want start pls somebody help me because am having "my life" on the machine

There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again.

Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

Macbook pro wont start up and stuck on a restart screen, after mountain lion installtion failure

I tried installing Mountain Lion on my Macbook Pro and the installation failed because my "hardrive was damage and could not be repaired" it then told me to restart my computer and try again which i did. However i am unable to even get back to my desktop because the Macbook starts up and i get the grey Apple logo and then this screen appears:
Instructing me to restart my computer, it has been stuck on this cycle for a few days now and i have no idea how to fix it.
Any help would be much appreciated
StephBeard

StephBeard,
if you still have your MacBook Pro’s original box, it can be found on one of the stickers on the box. If you don’t still have its box, it can be determined from your MacBook Pro’s serial number. If its serial number has eleven characters, write down the last three characters; if it has twelve characters, write down the last four. If you don’t have its box, please include in your reply those last three or four characters of its serial number.

My macbook pro has the grey screen of death.... i have tried a few things to get it re started.... it is not backed up and i really dont want to loose everything on it :(

MacBook pro has grey screen of death, it all began when I tried to install something new last night like my laptop asked and when it went to restart, it went grey....
tried start up in safe mode and nvram/pram
on safe mode it said ' the volume macintosh hd could not be repaired '
My MacBook has not been backed up and it would be heart breaking if I lost everything from it...
can anybody help?!!!

Be prepared for a broken heart...
It's obvious that you need a new drive - when you purchase one you should also purchase a USB enclosure for your old drive and connect that drive to your machine to see if you can rescue any data from it. You may have to purchase a utility such as Data Rescue 3 or DiskWarrior (each $100) to facilitate restoring some of your data.
And start a couple of backup schemes... when you can't afford to lose data, a couple of backup schemes can help.

Macbook Pro boots to grey screen but won't start up. How do I fix it?

Today I set my Macbook Pro on the couch but it slipped of and landed on its side (closed) on wood floor. Nothing broke, it all seems pretty normal. I pushed the power button to turn it on, but it only loaded to the grey screen with the apple and the spinning circle. I left it sitting there loading for several minutes, but nothing happened. I tried force shut down several times and restarted it. It still did the exact same thing. How do I fix it?

My Computer Won't Turn On

Macbook Pro (MC374LL/A) chimes + grey screen, then switches off

Hi
My MBP won't boot anymore
It switches on, chimes, displays a grey screen and then switches off
I have tried resetting PRAM [option]+[command]+[P]+[R],
booting with the following possibilities [option], [option]+[command], [C], [T], ...
I have changed the RAM
Nothing seems to make a difference.
Should I resort to the 7mins oven treatment ?
Not sure what to do
thanks
yann

Thanks for your replay Ogel
1) Safe boot doesn't work
2) Reset the NVRAM / PRAM doesn't work
3) Start up your Mac while holding the C key doesn't work
The DVD I manage to enter is immediately ejected
On each boot the grey screen lasts barely two seconds before the MBP switches itself off

Macbook Pro wont start, but pretenfs like it is going to and then turns off

So, I opened a game, the Mac crashed and, won't turn back on. Itll turn on for a few seconds and play that loud noise and appear like it's functioning properly and the little bar fills up a tiny bit but then it turns back off and repeats if I prompt it...any help?

Howdy xVaGuEx,
If your MacBook Pro is shutting down unexpectedly durning startup, I would suggest that you troubleshoot using the steps in this article -
OS X: When your computer spontaneously restarts or displays "Your computer restarted because of a problem." - Apple Support
Thanks for using Apple Support Communities.
Best,

Macbook won't start up all the way, just gray screen then shuts off...

When I turn my mac book on, it starts up and has the apple logo and the spinning gear thing. then after about 30 seconds or so, it shuts off. I tried the install disc and held c, then tried to repair my hard drive thing, but it said it had an error like this: "the underlying task reported failure on exit" and then under that it said something about 1 volume like not working or something and that was in red. anyone know anything else I could do to fix it? thanks

Hey man,
I regret to inform you that I am having the same issue. And I have found that EVERYTHING I have tried has not worked.
You can try all the things that are on the troubleshooting forum right here in the support section. But it didn't work for me. I even tried some further stuff.....to no avail. Some poeple have told me that I need to take out the RAM and try switching that. Haven't gotten to try that yet.
But from what I can tell right now, I'm gonna end up having to loose all my data and send it in and get a new computer. Which I like the sound of "a new computer"....but DON"T like the sound of "lost data." I'm a writer and musician...and I've archived my files on that of my music and writing....alas, the mourning process has begun.
But I hope that you end up in better shape! And do let me know if you find anything that works!!
