Macbook pro screen flickering brightness/black screen?

on saturday night I was using my MacBook pro and drinking water when my friend made me laugh so I accidentally spit like 5 drops of water onto my macbook screen. the drops leaking down into the base, not exactly the keyboard but just right under the screen where it would drip down. a instantly got a towel and dried it off but the macbooks screen statted flickering off and on. then it went permanently black but it seemed like it was still on. I tried to hold down the power button and it would make all the on and off noises just the screen wouldn't work. it would maybe flash for a second but then just go dark. I made the mistake of not turning it completely off when it first happened because I didn't know what to do but after maybe 10 minutes I turned it off and opened it up and kept it upside down the whole night to let the water come out if there was any. the next day around 12pm I turned it on and everything was working completely fine. no problems or signs that eer spit the water. then the next day (Monday) half way thru the day I was watching Netflix and I noticed every 5 minutes or so the screen would dim no matter what brightness I had it on and after a couple seconds it would go back to regular brightness. after like an hour it started doing that more frequently and it gave a black screen until I moved the cursor. I paniced and shut it off for the rest of day thinking it would be better the next day. well the next day (today) I turned it on and it was even worse. it's almost like the screen is having spaz attacks every 2 minutes. it'll go dim or bright randomly and then go black until I move the cursor and when it gowa dim there's these weird bright lights things coming from the bottom of the screen. but other then that the macbook works completely fine. iit's still usable, and the screen spasms are annoying but I could live with them. but first I want to make sure it's not going to get worse and worse everyday and just permantly die soon. im only 15 and Ive been dreading telling my parents what happened but if i have to replace something I have to tell them. I've tried researching what I have to replace but no one has my exact symptoms. I think I'd either have to replace the Lcd (whatever that is??) or the inverter. someone please help, thank you!!

  • My early 2008 Macbook Pro is suffering from black screen after Yosemite update

    My early 2008 Macbook Pro is suffering from black screen after Yosemite update. It ran beta 5 great but failed on restart after beta 6 install. There is no cursor but I can hear the HDD spooling up. I have tried booting in safe mode, PRAM reset and SMC reset but nothing works. After the first 5 days of every now and then trying to start it, it started fine. I used the machine all day with no problems, it had rolled back the install and was back on beta 5. I decided to try the update again, the same thing happened and it has stayed black for over a week now. It wont work with a monitor either. Help!

    Hello Adam,
    I would try instead of installing the beta software, to install the official build of OS X Yosemite from the Mac App Store to see if that gets you passed the no video issue when updating the beta software.

    If you replaced the Ram in your machine at any time, you may not have been aware of the fact that Apple computers have always been a little picky when it comes to 3rd party Ram.  Apple computers have always run very well on 2 different brands.
    Memory for iMac 2GB, 4GB, 8GB, 16GB, & now 32GB - OWC Certified RAM for Apple iMac with Lifetime Warranty
    This first link is from other world computing and none of us on these forums to my knowledge have heard of any bad ram from either Other World Computing
    or Crucial Ram.
    Crucial Ram
    The only difference I am aware of is that Crucial offers a download and will tell you exactly what Ram your computer is capable of using and the prices that are available.

  • MacBook Pro 17" late 2009 - Black screen on boot, not even a grey screen

    Got a monstrous problem.
    Started up my MacBook Pro (bought in Feb. This year, core 2 duo 2.88GHz/4 Gb RAM - basically the top specced model.)
    Booted up today, no grey start-up screen. No screen at all. Yet I can still log into Snow Leopard, but again no screen. Rebooted into boot camp, heard windows start. Managed to log in again no screen. Volume controls, keyboard illumination work. Just a black screen.
    I have tried resetting PRAM, etc. with no success. Cannot use hardware test as the screen simply does not start.
    Any ideas before I throw the effing thing from a 5th floor window in frustration?
    Is this the Nvidia problem other folk have experienced?
    I am tempted to ask for a new machine spending 2 months on and off with my previous MacBook Pro in and out of repair if this is a hardware problem that has been fixed in recent Macs.
    Regards,
    J

    I had the same problem just now. My 15" MBP (6.2). I followed the following steps and it worked for me. I used another Mac in my house to use screen sharing to accomplish these things:
    1) access the /private/var/vm/ directory on the nonworking computer from the working computer. This is invisble so you will have to press cmdshiftg in the finder and go to /volumes/YOURHARDDISKNAME/private/var/vm to get there or use an application that lets you view invisble folders like PathFinder.
    2) delete the sleepimage file
    3) delete the /system/library/extensions.mkext file
    4) eject the drive (drag to the trash)
    5) press the power button to turn off the non working computer
    6) turn the nonworking computer back on normally(cross your fingers) then if it works,
    7) open up the the terminal.app in /applications/utilities
    8) type sudo pmset -a hibernatemode 0
    9) make sure there is no sleepimage file again
    That worked for me...hope it helps for you!

  • Late 2011 17inch MacBook Pro OS X Mavericks Black Screen on reboot

    I'm typing this on a Windows XP PC
    I upgraded to OSX Mavericks from Mountain Lion a couple of days ago, The upgrade went OK and my MacBook functioned OK.
    Today I decide to re-boot it. All I see now is a black screen. The keyboard backlight comes on, but if Itry to type in my password (blind) it just makes the alert sound. I have attempted to use Command R on reboot, but this is not giving me anything - I'm probably not pressing it at the right point in the boot process.
    I bought a Mac because it was easier to repair and more reliable than the alternative....
    I haven't a clue what to do next - anyone have any ideas? The Mac is vanilla, it has no external devices attached and most of the software on it is Apple.
    Tried Safe Boot, no joy,

    I have the same problem. I went to the Apple Store and they say that the LCD screen is faulty and needs replacement (500 pounds - 800 USD).
    I'm completely devastated by Apple's low quality and terrible customer service.. In my third year the motherboard, the hard drive, the charger and the screen failed. Lesson learnt, I will never buy again Apple junk. The most expensive computer I've ever bought has been the worst.

  • Mid-2010 macbook pro has started having "black screens"

    apple store diagnosed as "software failure".  they wiped it clean & gave me instructions to reinstall/restore from backup at home.  successfully reinstalled but another black screen after about an hour. 
    i am NOT a computer person so i need kindergarten language/instructions/suggestions (fitting, as i was a kinder teacher).  i am a 6 hour roundtrip to the apple store, living in a rural town after 35+ years of living in an area of 6 million with MANY apple stores close by. 
    has this happened to anyone else & if so, can you tell me how you corrected it?  again, VERY elementary language please!
    thank you!
    p.s.  i have since upgraded to OS X 10.9.2 & while it's listed that i have vmware fusion (i do), i don't use it...

    You may have the mid-2010 problem. There's an issue with the graphics module on that machine. There was a program in place to replace the motherboard within 3 years of purchase, but you're probably outside of that. Some folks have supposedly gotten theirs changed outside of that period, so you can try. There's a very specific test Apple has for this called the VST, which should detect the problem. I don't think all the Genius Bar folks are aware of this issue, so it's best to ask for it specifically. Take along a copy of your kernel panic report if you're getting one.
    http://support.apple.com/kb/TS4088?viewlocale=en_US&locale=en_US
    What you can do to use it is download gfxstatus from http://gfx.io and force the graphics to Intel. That will lessen the panics at the expense of graphics speed.
    You may be eligible for a depot repair, which is a flat rate of about $310. Ask at the Genius Bar.

    Your kernel panic is being caused by a fault, of some kind, on your GPU.
    If I were you, I would make an appointment at your local Apple Store/AASP and take you computer and a print out of the kernel panic with you.

  • My macbook pro has had a black screen and wont turn on after pulling out usb

    6 months ago i pulled a usb out of my usb port and my laptop switched off and didn't turn on for a week, and it's just happened again after pulling out a HTMI cord that was connected to my television? have i blown up my macbook? SOMEONE HELP

    Try resetting the SMC. Be sure to use the correct method for your computer.

  • MacBook Pro beeping 3 times, black screen. How do I fix it?

    This started happening after the computer suffered a small drop from futon to the floor. I researched and saw that signal means there is a problem with the RAM, could the Ram be loose? If so how do I fix this

    In non-Retina models, you need to remove the smallscres on the bottom with a #0 (that is a real size specification) screwdriver.  Lowe's or RadioShack would have it.
    Go to ifixit.com for picture instructions.  And do not lose those tiny screws OR exactly which hole each came from because there is more than size holding the bottom.

  • My macbook pro will turn on but screen stays black.

    My macbook pro will turn on but screen stays black. There is no sound on start up and keys dont light up. I have done all the resets:
    I disconnected the computer from the power cord, and from all other cables.
    I held down the power button for several seconds to turn off the computer.
    I let it sit 5 minutes.
    I restarted the laptop while holding down the Shift key and nothing happened.

    Zane W is giving you good advice.  Take it to an Apple store genius bar and have them examine it for free.  You then will know what the issues are and then can make informed decisions.

  • Guide to Upgrading to Windows 8 on the T540p (+fix for brightness/black screen on wake)

    Hello all. I recently received my new T540p running Windows 7. Although I probably would have qualified for receiving Windows 8 recovery media from Lenovo, I went ahead and did the upgrade myself since I had a copy of Windows 8 laying around (and because I'm impatient). I'm fairly tech-savvy and expected the process to go smoothly; boy was I wrong. I decided to write up this little guide after having a thoroughly annoying time upgrading in the hopes of saving someone else out there from the hassles I underwent.
    NOTE: The most troublesome part of the whole process was figuring out why the screen brightness was no longer adjustable and the display would not turn on after waking from sleep (black screen) after upgrading to Windows 8. Skip ahead to step #9 if that's the issue you're having.
    Step #1: Make a bootable recovery disc or USB drive
    This is important in case anything goes wrong during the upgrade or you decide you despise Windows 8 and want to bring back Windows 7. The T540p comes with a recovery partition in the hard drive (like most laptops nowadays I assume) which allows you to completely wipe your computer and reset it to its original factory state (the same as when you first received your computer). This is normally done by restarting your computer and hitting the enter key to interrupt normal startup and selecting the recovery option from a menu. I wrongly assumed that I would still be able to conduct the recovery after installing Windows 8, but for some reason after upgrading I was unable to start a recovery from the recovery partition. Thus it's important to create a set of recovery discs or a recovery USB drive yourself BEFORE starting the upgrade. Lenovo includes a program which makes this step very easy; see this page for details: http://support.lenovo.com/us/en/documents/ht004960
    Step #2: Uninstall certain programs BEFORE upgrading
    I skipped this step because I forgot about it. I haven't noticed anything adverse (aside from the brightness/display problem which I assume is completely unrelated), but Lenovo does suggest to uninstall certain programs before upgrading so it's probably wise to do so. Here's the list:
        - DisplayLink Core Software
        - Intel(R) USB 3.0 eXtensible Host Controller Driver
        - Lenovo Solution Center
        - RapidBoot
        - ThinkPad(R) Bluetooth with Enhanced Data Rate Software
    See this page for details: http://download.lenovo.com/lenovo/content/windows8/upgrade/think/notebook2_en.html
    Step #3: Download and save wireless drivers to external media BEFORE upgrading
    After upgrading, I discovered my wireless didn't work and thus I couldn't connect to the internet. I wound up downloading the wireless driver to my phone and transferring it to my T540p. You could also use an ethernet cable to connect to your wireless router or cable modem. But if you have a USB drive, CD, DVD, external hard drive, whatever, save yourself the hassle and download the wireless driver ahead of time. You will need to know the brand of the wireless device (Intel or Realtek); look it up in your email receipt or from the Windows Device Manager under "Network Adapters". Mine was Intel. After figuring out the brand of your wireless device, go to the T540p drivers page here: http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t54... Look for a drop-down menu that says "Component" and select the option "Networking: Wireless LAN" (LAN, not WAN!). The page will refresh to show only the wireless drivers. Select the Windows 8 64-bit driver that matches your brand (I'm assuming all T540p laptops are 64-bit. If I'm wrong, please correct me). Download that sucker and put it to on the external media of your choice to use later!
    Step #4: Begin Windows 8 upgrade
    You'll obviously need to have a valid Windows 8 key or purchase a copy of Windows 8 for this step. I had a valid Windows 8 key that had been used on an old computer which died (hence my new Lenovo), so I reused it. This requires Windows 8 to be activated by phone which isn't nearly as scary as it sounds. We'll get to that later.
    There are two ways to do upgrade: use a Windows 8 installation DVD or download a web installer. I had a Windows 8 key from a previous web installation and went with downloading a web installer. If you have an installation DVD, just insert it and get started. If you prefer to download a web installer, go to this page: http://windows.microsoft.com/en-us/windows-8/upgrade-product-key-only  I think product keys are tied to either Windows 8 or Windows 8.1, so select the one that you have a key for and download the appropriate one. If you're not sure, you may have to try both.
    During the upgrade, you will be asked whether you want to download updates (I assume this updates the installer) and afterward you will be asked to enter your product key. For some reason, when I downloaded the updates my product key would get rejected. I just restarted the Windows 8 installation, skipped the updates and then my product key was accepted. I don't know if this is tied to the fact that I was reusing a Windows 8 key (again, which had been used on a now dead computer) but if you find your key getting rejected then you may find skipping the updates helps. If this doesn't work and you're using the web installer, try downloading the other web installer (e.g. if you're using the Windows 8.1 web installer and find the key is rejected even after skipping updates, your key may actually be for Windows 8 and you should try downloading the Windows 8 web installer).
    The installation itself should be a fairly straight-forward process. There are lots of guides online in case things go awry. If you have any trouble or errors, you should hopefully have made recovery media for worst case scenarios where you need to start from scratch.
    Step #5: Install wireless driver & connect to your router
    You should now have Windows 8 up and running on your system, but no wireless. Now's the time to use that driver you downloaded earlier. Install it and you should now have wireless access. Connect to your router and get online so we can start some badly needed updating!
    NOTE1: your touchpad/trackpoint/keyboard experience will be especially funky at this point. That's because the drivers for them haven't been installed. Normally the touchpad won't be active while you're typing, but because the drivers haven't been installed you'll notice you'll accidentally move the mouse or click while typing (e.g. when entering passwords). Not to worry: this will go away when we install the Lenovo drivers now.
    NOTE2: your function keys won't work (adjust sound, adjust brightness, etc.). That's also because of the drivers.
    NOTE3: you may notice your screen's brightness may not be adjustable even from the Windows menu. Again, that's also because of the drivers. Hang in there!
    Step #6: Activate Windows
    Now that we're connected to the interwebs, it's time to activate Windows. If you're completely new to Windows 8, here's where you go:
    -move your mouse to the upper right corner then move down
    -select "Settings"
    -select "Change PC settings" at the bottom
    -select "Activate Windows"
    This is where you'll enter your product key. As I've said before, my product key had already been used on an old, now dead, laptop. Reusing a key requires you to do a phone activation. If you find your product key gets rejected, go to the phone activation option and follow the instructions. An important note: at some point you will probably be asked how many devices/computers you installed Windows on. The correct answer is "one"; if you accidentally give another number, you'll need to call again and start over. (I'm assuming you're not doing anything illegal. As far as I know, there's nothing wrong with you reusing your key so long as you're no longer using the old computer Windows 8 was installed on, e.g. when that old computer no longer works. But if you're trying to install Windows 8 on multiple computers and you can afford to buy a new copy of Windows 8, shame on you. It takes a huge team of coders and support staff to make a product like Windows happen; help them pay their bills by purchasing a legal copy of Windows 8. Students can even get a copy for less than $70 with proof of student status. http://www.microsoftstore.com/store/msusa/en_US/pdp/Windows-8.1-Pro-for-Students/productID.288769600...
    Step #7: Install Lenovo-specific updates and drivers
    I typically hate all the crapware and bloatware companies include with new laptops, but Lenovo does make some which are useful. Their system updater should take care of downloading the rest of the drivers you'll need instead of having to download them all individually (with one exception: the graphics drivers may require a separate download later). Download the system updater here and keep running it until there are no more updates to download: http://support.lenovo.com/en/documents/ht080136
    Step #8: Install Windows Updates
    Load up Windows Update and start installing. If you're completely new to Windows 8:
    -move your mouse to the upper right corner then move down
    -select "Settings"
    -select "Change PC settings" at the bottom
    -select "Update and recovery"
    -click the "Check now" button to check for updates
    -click the "View details" text link to see the available updates
    -click the "Install now" button to begin installing immediately
    (Yes, the Windows 8 interface is dreadfully unintuitive unfortunately. Watch some Windows 8 tutorials on YouTube if you find yourself having trouble. Already looking forward to the next version of Windows!)
    You'll also want to download the Windows 8.1 update if you installed only Windows 8 (the update to 8.1 is free). The download is available from the Windows Store.
    Step #9: Install graphics drivers (if you're having display problems: unadjustable brightness, black screen on wake from sleep)
    As I stated earlier, this was the most frustrating part of the installation process. My T540p came with only an Intel HD Graphics 4600 card, but it seems some others include a dedicated NVIDIA card. Whatever updates were installed with Lenovo's System Updater and via Windows Updates didn't seem to do the trick. I even updated the driver with the latest from the Intel website to no avail.
    The solution, at least in my case, was simple: go to the T540p driver's download page and download the graphic card drivers appropriate for your system. Go here: http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t54... Look for the "Component" drop-down menu and select the "Display and Video Graphics" option and download the Intel and/or NVIDIA drivers appropriate for your system. (I have no idea what the Intel Wireless Display driver is for, so I avoided it thinking I don't need it)
    BONUS Step: Go to ninite.com to download commonly used programs
    Shameless plug for one of my favorite websites. It lets you pick from a list of commonly used programs, then downloads and installs each of them all automatically (and skips all toolbars/extra junk downloads). Makes getting started on a new computer a breeze!

    Hello Yolanda,
    a) I noticed that I can´t install MediaCenter on Win8, but just on Win8 Pro.
    b) My problem is, as described, that installing "MediaCenter" on either "Win8 Pro" or "Win8.1 pro", though the "Media Center" key is accepted,
    which I once 2 years ago downloaded on ANOTHER "Windows 8 Pro" computer, for free as it was a gift of Microsoft  at that time - You could reserve = get up to 5 Media Center licenses per "Windows 8  Pro" computer for later use
    on OTHER "Windows 8 Pro" computers - but never used ( i.e. NEVER USED FOR ACTIVATION ),
    but after the first reboot, I am running "Windows 8 Pro with Media Center" WITHOUT LICENSE, as shown in the system screen.
    Neither my "Windows Media Center Key" nor my "WIndows 8 Pro key" is then accepted to change the situation - I mean the keys I entered just before during the installation process of "Windows 8 Pro" and "Windows Media Center".
    I am shure that I did not use the "Windos Media Center" key, as I have a list of personal keys I got for free from Microsoft, and I marked those 2, I used for other "Windows 8 Pro" computers.
    So fact is, that with my brand-new computer, 32 Gigabytes of RAM, 4 Cores, "Win8 Pro" installed, I am forced to avoid the installation of "Windows Media Center", though I got valid licenses.
    So your answer was not quiet helpful, as it does not change anything.
    Sincerely
    Rolf

  • What cable do I need to buy to connect my Macbook Pro (2011) to a VGA screen? I tried the "Mini DisplayPort to VGA", but apparently it doesnt fit the 2011 Pro version...

    As the topic says,
    What cable do I need to buy to connect my Macbook Pro (2011) to a VGA screen? I tried the "Mini DisplayPort to VGA", but apparently it doesnt fit the 2011 Pro version...
    Help me out please.

    Yes ... minidisplay
    But what I do not like in that picture (my personal view, others may think differently), is that there is much plastic around the connectors where the cable must fit.  You may ot may not be able to get the cable to *fully seat* with the adapter.
    Other adapters (http://www.microcenter.com/single_product_results.phtml?product_id=0334087, yes I know this is a DVI) hve no plastic barriers to connections.

  • My macbook pro is stuck on grey screen with apple symbol in center with the progress circle under it continusly spinning. After I had turned it on. Prior to turning it on I had to force close and shut down a few hours prior. Please Help?

    My macbook pro is stuck on grey screen with apple symbol in center with the progress circle under it continusly spinning. After I had turned it on. Prior to turning it on I had to force close and shut down a few hours prior. Please Help I have tried everything I know to do

    Unfortunately this means that there is a problem in the boot sector of your hard drive. It might be indicative of a fundamental corruption in the coding that allows your computer to boot your operating system from your hard drive. I had this problem twice and it resulted in me having to get a new hard drive and restore my data.
    In other words, your computer can't talk to your operating system so you can't access your data.
    Here is my advice: DON'T CALL APPLE TECH SUPPORT though they are kind and usually helpful it will take you an hour just to explain the situation and they will only tell you to do what I'm gonna say here.
    First: Shut down your computer completely
    Two: boot up while holding down the following keys: command, option, p, and r. The computer will reboot 3 times. This solution will likely fail so if you're frustrated skip to the next step.
    Three: Boot up while holding down the option key. Select recovery drive. Select your default language. Select disk utility, click on Macintosh HD, and select "verify and repair volume." Likely the verification will produce some line like "unused node not erased." Or something like that. If anything using the words "node structure" comes up, you need a new hard drive.
    If after verification and repairs you still can't boot I sincerely hope you have apple care because you will need a new hard drive. Set up an appointment to come in to the apple store, they will tell you to go and get data recovery, just ask them to give you the old hard drive. Unless you have an up to date backup in which case you can just restore from that. If you're lucky the only issue is with the boot sector which means that if you ask them to give you the old hard drive, you can buy an enclosure and you have effectively been given a free external hard drive. It still works to store data just not to load an operating system.
    If you have a back up drive bring it to the apple store and they'll do the whole thing right there, it should take around an hour and a half but may take longer.
    Hope this helps, it's annoying but it's your safest bet.
    All the best.

  • How to erase a Macbook Pro Hard drive when the screen is dead

    I have a Macbook Pro (2007) with a dead screen and a motherboard issue. Just bought a new macbook and i was planning on transfering the hard drive over and selling my pro on ebay for parts, Is there anyway i can securely delete my data from the computer without seeing it on the screen before i decide to sell it?

    Be sure your dead Mac isn't covered by this program:
    http://support.apple.com/kb/TS2377
    If it is, you can get a free repair, and it would be worth a lot more on EBay.
    Good luck!
