My MacBook Pro has a white screen when I turn it on

When I start up my MacBook Pro. It just ha a plain white screen and I can also hear a faint beeping (like if you were on a desktop computer holding down a lot of keys on the keyboard) please can someone help me!!??

I can tell you what I did the last time this happened to me:
I made a careful note of my Display settings when my computer started up correctly and everything looked fine
... and, I ensured that the same settings were there the next time I restarted (and it happened that my screen didn't appear to display correctly) I checked these settings. If they had changed, I chose the one that 'worked' for me and it 'set' thereafter. In my case, it was 1280 x 800.
If I were you, I wouldn't shut down my computer too often (just telling you what I do.) I shut down mine only after a week or 10 days so that it can 'clean itself up.'
Hope this helps.

    Will not show up in safe mode, will not show when started from Windows 7 DVD.
    I suspect the Mac update wiped out my PC video drivers but can not think of a way to re-install?
    Can see the PC volume from Mac side with files.
    I've looked at all the online solutions so far and have tried most of them without success. Please help!

    For anyone else who finds their way here like I did, this link did it for me: https://forums.geforce.com/default/topic/527599/windows-8-issues-solved-please-r ead-if-you-39-re-having-black-screen-and-or-flickering-/
    Specifically, the posts by Dunsany and valkyr did the trick.  I booted in safe mode, uninstalled and deleted the Nvidia driver, disabled automatic driver installation, and restarted normally.  I then manually downloaded and installed the previous Nvidia driver for my graphics card (which at the time of this writing was 335.23, rather than the latest which was 337.88), and everything is now bueno!
    Two hiccoughs along the way: First, when I tried to uninstall the Nvidia driver the first time, when I restarted I got the login screen (which was a good sign), but it quickly went black again.  I powered down, restarted in safe mode again, and repeated the uninstallation process, and it worked the second time.  Second, when I started the manual install of the 335.23 driver, the computer played a sound similar to the one for disconnecting a USB device, and the screen went black.  I'd seen a lot about trying to increase the brightness (though it hadn't worked up to this point; but if you haven't tried it yet, might as well); I tried it, and it worked! So far I'm back up and running. [/fingers crossed]
    Hope this helps someone else!

  • Macbook pro has a white screen and is basically not allowing me to do anything.

    My sisters macbook pro has a blank white/grey screen for some reason. We have been at school all day, we come home to find a small dent on the right of the trackpad, but the laptop had been closed all day. I have already looked at other peoples discussions talking about restarting and putting the Mac OS disc to reinstall and things like that... But the laptop is not allowing me to eject, or put anything in it. I have clicked on all different combination of buttons but still the white/grey screen. There is a disturbing whurring sound when the laptop starts up, almost like a small scratching noise and something has definetley been broken. I put the charger in and the small light goes orange teling us its not completley done for.
    Has this happened to anyone else before?!
    And we really need some HELP !!

    The lid was opened and something was dropped on it is my guess.

    If you get a external USB or Firewire drive, you can hold c and boot off the installer disk #1 that comes with your computer, the second screen in is a Utilities Menu and Disk Utility.
    Select the EXTERNAL DRIVE and Erase, format HFS+ Journaled GUID partition.
    When that's completed quit Disk Utility and your back in the OS X installer, install OS X on the EXTERNAL DRIVE.
    When that's complete quit and reboot hold down the OPTION KEY and select the External drive to boot from.
    Now GRAB THOSE FILES!!! 
    After that you can do what you want to the boot drive, if you can't fix it, you can always install OS X again (without formatting) and it should leave your programs and files alone. But if something goes wrong you have a copy on the external drive.
    If for some reason you can't access your internal drive, either booted from the install disk in Disk Utility or via the external drive, it's possible your hard drive died.

    macbook pro boots to white screen and a ?

    Gus@MaggiesFarm,
    try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the Mac OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it get past the white screen now?

  • Why does my Mac stay on the white screen when I turn it on?

    Why does my Mac stay on white screen when I turn it on?

    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 boot failure is to secure your 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 your last backup, you can skip this step.   
    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 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.”
    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. Use the working Mac to 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.
    Step 2
    Sometimes a boot failure can be resolved by resetting the NVRAM.
    Step 3
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 4
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot 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.
    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 5
    Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
    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.
    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 corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
    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. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
    If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 6
    Launch Disk Utility in Recovery mode (see Step 1.) Select your 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 reboot as usual.
    Step 7
    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.
    Step 8
    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 Time Machine or other backup.
    Step 9
    This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. 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 boot 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 10
    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.

  • White screen when I turn the Satellite M50 on

    I intermittently just get a white screen when I turn the computer on. Usually the problem is solved by switching the computer off and trying again - but sometimes I get a white screen again.
    It seems to be connected to use of external devices - can anyone give me clear instructions about what should/should not be connected when I start and shut down the computer? Or any other suggested solutions?
    Thanks

    Thanks for your reply/advice - and the tip about Antivir. I used to use AVG and then Norton came as a package with this laptop....will have a re-think when my subscription need renewing.
    I have updated the display/graphics driver but am still having the same problem of a white screen at boot-up. On reflection I think it is possibly a loose connection as I have just been a long trip with the laptop - including a fairly bumpy 4 hour bus ride - and I recall having the same problem several months ago which self-corrected after a similar trip (taking it down to a Toshiba ASP who never saw it as they were closed for the week-end and I had to get back to work!). This may sound strange but I took the laptop for a walk yesterday to see if any loose connection would shift and it then booted up on the second attempt rather than the 8th!
    I guess I'll have to take it to the ASP - unfortunately it's no longer under warranty.

    Problem solved. High temperature caused this issue

    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.

    My Mac book pro has been running slow, so I thought I would shut down and reboot. It wouldn't reboot past a white screen and an apple logo. I have rebooted several times and after an hour or so it still won't go any further. Any suggestions?

    Howdy Lowana42,
    Welcome to Apple Support Communities.
