MacBook Pro will not start up, get start up chime but screen does not light up. Any help?

Upon start up I hear optical drive checked, then get a start up chime but the screen does not light up. I have shut down by holding down power butto for 10 seconds also pulled battery and A/C power.

I had this same issue but after a new hard drive/ram install.
What solved the issue - and I hope this helps someone else who has the same problem:
1). Install new hard drive (with or without osx pre installed) or leave old one in in your case.
2). Remove all ram
3). Power on and wait 1 minute
4). Hold power button until it turns off
5). Install ram
6). Power back on
7). BOOM! It works again.

Went snorkeling... phone was dried, disassembled and still gets calls and txts but screen does not turn on... HELP??

Hey Guys,
So my phone was my snorkeling buddy last week for a few minutes... I wasn't out in the water for longer than like 5ish minutes. It is a Verizon 32gb iPhone 4. I've had a few problems with it before as the previous owner dropped it in some water which has not only fried both the wifi and bluetooth, but also caused the home button to work sporadically and the LED flash to stay on like a 1/3 of its power 24/7 even if the phone dies...
Anyways,
about half an hour later of discovering 4 ft of water the phone was stuck in white rice (had to go on a rice hunt) and dried for several hours before I soaked and drowned it again in fresh water to try to get the salt out... One omen that I saw was that the eternal flashlight was finally, off.. after this, I stuck it back in rice for another day and a half and then stuck it on my ihome... the apple icon flickered and then went away. I plugged it in a few more times and finally got to the lock screen and started to hear txts and alerts come in. however, the screen was unresponsive and i couldn't unlock it. not sure if it was just me but each time i plugged it in to try to get to the lock screen, the screen itself went from ok condition to having dark streaks diagonally across the screen. After this I stuck it back in the bag of rice before finishing off by letting it sit in the hot desert sun for a few hours..
Several days after this the phone was taken apart and there appeared to be little to no moisture. however, there was some rust. a newer battery was popped in and the phone itself was able to receive txts and calls (you can call it and swipe the bottom of the black screen to answer and talk through it).
is there anything i can do to fix the black screen or am I doomed to get another phone and loose all my pics and videos?????????? as i haven't backed up the media...
Thanks

Apple won't touch it. It was opened by an unauthorized party. It is not eligible for an out of warranty replacement. Your only option is to buy a new phone.
Apple does not sell iPhone parts at all. If you want to take your chances with a 3rd party repair service or try to fix it yourself, the only parts available are counterfeit parts, stolen parts, or salvaged parts.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login 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.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

The idea to jumpstart by change was not the smartest one, but gives you an opportunity to use that "temporary" account as permanent. You do not have a choice cause obviously despite you thinking that old account is no more -it does exist on Apple servers. And if you are unwilling to share your [email protected] with friend, just create one extra [email protected] for your friend. One suggestion - do not use gmail.

I advise to reply to the one you want to reply to.
You have had good information here. I will not repeat that here.
I would like to add:
you have incompatible software: start in SafeMode, read Woodmeister and see if it is free of issues.
Akamai is crap software needed or not, Huawei the same.
It is very possible that the keygenerator you used for generating a key for some softwares has infected your mac.
The non-regular software with the false key(s) are not compatible probably or generate malware. Luckily you can not update them automatically because the keygenerator blocked the software for contacting the developer... I propose to consider getting rid of those softwares by really good uninstalling.
You have a beautiful mac, don't degenerate it with crapped software. There are alternatives for expensive software, for example Adobe Photoshop has a free alternative (with a less beautiful interface) in GIMP. And so on.

I have a 16GB iPhone 3GS. Tried synching my phone through iTunes (11.0.1 I think... on a 2009 Macbook Pro). Now when I connect to iTunes, it says it does not recognise the content on my phone. Is this because my phone (and laptop) are too old?

Also, when I tried to Restore the settings, an Error Message pops up that says " The iPhone software update server could not be contacted. The requested resource was not found.
I'm trying to free up space on my phone by removing [literally] thousands of old photos which were originally synched to the phone, because I had forgotten to uncheck the photos button when I synched it ages ago.
I have also tried synching it on my 24" iMac (running OSX Snow Leopard). But again, when I try restoring the phone through itunes, it says the file is corrupted. It sggests unplugging the device, and then plugging it in again. I have done this numerous times with no success.
I'm guessing it must be because my phone (and versions of iTunes, and OSX) are all too old.
Please can anybody help.
Cheers,

Im trying to hook up my macbook pro with Lion os to new tv with Kanex mini displayport hdmi with no luck, any help?

I'm trying to hook up my macbook pro to my new LG tv, I have the desktop screen on my tv (I was told I had to open a 2nd desktop and then drag my dvd screen into it, it still doesn't work.

ok so you have a macbook pro with minidisplayport and you can see your desktop on your LG screen?
go to system preferences>displays>arrangement and turn off Mirroring (if it's on). This will give you two separate areas and look similar to this.
If you want quick access to this setting click the "show displays in meny bar"
a little pointer, you see on my setup that there is now one screen with no white bar at the top and one with. This marks where your main screen is (and where the menu bar and dock appear) you can click and drag this white bar to your new LG tv.
Most new tv's have a setting to fit the screen to the tv size. This is a setting that allows for edge to edge persision instead of overlapping which you'll see in older tvs. Take a look at your tv's manual for more about this sort of connection.

I can not boot my MacBook Pro. How do I get and save the data that is not backed up??

I can not boot my MacBook Pro running on Lion 10.7.4. I pressed control, comment P and R keys and O got to the disk utility, then I tried to repair disk and it can not be repaired. I get a message that tells me to back up as much data as possible ?. But if I can not open the computer how can I save my data??
I have a back up until 2 weeks ago on time machine. but the work of the last 2 weeks is extremely important how can I get it??
If I use m time machine backup do I loose the additional data of the last two weeks!,
Please help.. It's a huge amount of work that I have done and can not loose it

If it were me, I'd get a new hard drive or SSD and put it in an external enclosure. Boot into the recovery partition, format the new drive (not the old one) and install the OS to it. Shut down the Mac, open it up, and swap the drives. You may be able to read your data from the old one externally if you're lucky. If you're very lucky you may be able to use Migration Assistant to move all your stuff to the new drive.
Look at ifixit.com for the exact procedure to get to the drive on your model. If it's a unibody it's pretty simple.

My iMac doesn't start. Get the apple on the screen, nothing more happens. Any clues?

Rebooted - get the apple on the screen - but nothing more happens. What to do?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
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 a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
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 in OS X 10.9 or earlier, 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.

Late 2010 MacBook Pro 15", upgraded to Lion on Sat 23rd no external display does not work

Hi all,
Wanted to ask this question here see if anyone might have a solution to my problem. I have a Late 2010 Macbook Pro 15" which I upgraded to Lion yesteray. Ever since that upgrade when I try to connect to my TV to watch a video no joy the image looks like the colours are out.
I have tried it on different resolutions and always the same. Then for some reason the MacBook Pro split the screen in two. So now I see the right of the screen on the left of the TV and the left on the righ with a big black line done the middle.
Priror to the Lion upgrade everything was fine. Only since Lion has this been a problem.
I am using a Minidisply to HDMI cable to go direct into my Phillips 42" Plasma, and I have not got a clue why this is doing this. The strange thing is it works ok on my Samsung BX2450 down the same cable no problems at all just the TV that has issues.
Any suggestions?
Cheers

Am using Macbook pro mid 2010 running on OSX 10.9.5. It does not read my old Seagate back up plus ITB ext hard disk which opens and works on snow leopard. The back ups were made on snow leopard and mountain lion. How do I make it work on Mavericks?

I have been making back ups on a Seagate Back up plus drive on a macbook pro running on Mountain lion. Sadly the mac was stolen and all I had was the seagate back up. I tried opening it on my old iMac running on snow leopard and after several visits to this forum managed to open it. The data was safe and sound. Now I have received a hand me down macbook pro which runs on osx 10.9.5. I'm assuming there is a compatability issue as the drive does not come on at all when I hook it up to the usb port. I checked the seagate drive once again on the imac and its light came on on that system. Then I suspected there may be a problem with this macbook pro usb port. But it seemed to work fine when i hooked my camera cord into it. Is it that I must reinstall mavericks. In which case how do I back up before reformatting or reinstalling. BTW I did the command+ R thingy and repaired my internal Hard disc which was showing errors. What do I do next, your help is most appreciated if you have had a similar problem.

Your 2010 MBP would be able to handle Yosemite, but I would strongly suggest that you get the current problem sorted out before trying to upgrade to Yosemite. I'd also recommend another backup that isn't created by Time Machine if you are thinking of upgrading. SuperDuper and CarbonCopyCloner can make bootable clones of hard drives. If you clone your existing system to a fresh external drive, you would be able to boot from that drive and recover quickly in the event that your Yosemite upgrade didn't work out. Time Machine backups are not 100% reliable.
It's possible that, if your internal HD is the one that shipped with your MBP in 2010, it may be failing. If it keeps needing repairs, that is probably a sign that it is approaching the end of its useful life.
Have you run Disk Utility's Repair tool on the external drive as well?
I mentioned the hub because some people have reported here that attaching their USB 3 drives through a USB 2 hub solved some disconnection problems. A good-quality powered USB 2 hub won't cost much.
My most recent brush with random disconnections involved a nice new OWC drive enclosure. I used the cable that came with the drive, but the drive kept disconnecting. Using a different cable solved the problem. You wouldn't expect that what appeared to be a high quality cable would be a problem straight out of the box, but it was.

I recently moved my iTunes folder to a portable drive to make space on my macbook pro with Mavericks, and now the space is still taken up by back ups? any help to clear this space up would be greatly appreciated! Oh btw, macbook pro backs up to time caps

Im trying to free up some of the space on my macbook pro, its been filled up with itunes hd movies, so i purchased a 1TB portable hard drive and moved all my itunes files to it to free up some space. When i went into about this mac and checked storage, it says i have over 400GB's of back ups. I back up everyday through time machine to my time capsule, not sure what to do, any help is much appreciated! thanks

When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself, nor should you disable them or Time Machine.

MacBook Pro will not start up, get start up chime but screen does not light up. Any help?
