My screen shut off and on twice. What's wrong?

My battery is at 36% and all of a sudden, my screen went black for about two seconds, then came back on for a second, then repeated by came back on and remained on. Has this happened to anybody else? What's wrong?

  • POP shut-off and strange behavior, what should I do?

    Hello Everyone!
    I just purchased a Powerbook 1GHz 17" (used), that apparently was recently sent to apple and received a new logic board, a new case, and new parts for the airport extreme.
    I started working with it today, had it plugged in to the power adaptor, and after only a few hours, I suddenly heard a POP! and everything went blank.
    I started it up, it acted a little finicky about starting...
    Worked with it for a few more hours, again, without warning, heard it again... POP! and everything went blank.
    This time, I had a little more trouble getting it to start up, tried holding down the powerkey... after 5 seconds of holding it down, I heard this tone... then the sleep light on the latch blinked for a period.
    It then started up normally.
    I continued to work with it, I installed Dreamweaver, and when it was finished installing, I entered in the Serial number, and the moment I pressed "continue", the screen changed to grey with vertical "pinkish" lines.... is that related to the two POPs?
    I did some reading, and decided to try taking out the RAM, I have an extra 256MB to test it with, so I swapped out one of the RAM chips, we'll see what happens.
    Can any of you guys give me any sort of indication as to what might be the problem, what I should test or look for?
    Also, the POP sort-of sounded like a fuse that just popped, what could that be?
    Thanks in advance for any help!

    shut down like that is not very good.
    power flows from the power adapter to the so called sound board, then to logic board and from there to display and the drives.
    here you can check the warranty by entering serial number where it says "About Your Support Coverage"
    http://www.apple.com/support/
    see if it works from the battery with power adapter disconnected (in case it's bad adapter), or from the adapter with the battery removed in case it's bad battery.
    otherwise you may wnat to backup important files and get it diagnosed by authorised service provider.
    if the logic board was replaced recently, it will have 90 days part warranty from the replacement date.

  • I have an iPad 2 and all of a sudden I have no sound in game apps. I have usual volume in videos and YouTube, I do get volume for games if I plug in headphones. I have switched to screen lock off and on again and I have also done a reset twice.....help :)

    I have an ipad2 and all of a sudden I have stopped getting sound in my game apps. I get normal sound on YouTube and I player and downloaded DVDs. If I plug headphones in then I can get sounds for the games. I have switched the lock screen button off and on again and done a reset twice, can anyone help me with this?

    Check your settings. The iPads have a small switch on the right edge. It can be used as a rotation lock to keep the screen from automatically reorienting itself as you move around, but you need to have the tablet’s settings configured properly. That same switch, right above the volume buttons, can also be set to function instead as a mute button to silence certain types of audio.
    If the switch is set to work as a mute button, you can change its purpose to “screen-rotation lock” by tapping the Settings icon on the home screen. On the Settings screen, tap General on the left side, and on the right side of the screen flick down to “Use Side Switch to.” Tap to select Lock Rotation or Mute to set the button’s function. Even if you set the side switch for your preferred use, you can still mute the Mini or lock the screen. Just double-click the Home button, and when the panel of apps appears along the bottom edge of the screen, flick the row from left to right with your finger. Tap the icon on the far left side of the row to either lock the iPad’s screen or mute the iPad’s alerts, notifications and sound effects. Music, podcasts and video are not muted unless you turn the volume all the way down.

  • Macbook Pro running very slowly, randomly shutting off and overheating. No idea what the problem is! Please help!

    I got macbook pro about a year and a half ago and up until now it has been running fine.
    However, in the last few days, it has been started to run tediously slowly!
    It wont allow me to open applications and i have to force quit out of any applications I finally manage to have because they freeze or stop responding.
    On Google Chrome, pages become unresponsive every few minutes.
    Even writing this post took more than 20 minutes as the laptop kept freezing and the webpage became unresponsive.
    It also randomly shuts off and when it restarts, a message comes up saying my Macbook was restarted because of an error.
    I haven't downloaded or updated anything that I know of recently that would have caused this.
    Ive been reading through some of the fourms on this and I thought it'd be helpfull to post some of the information you may need to help me solve this problem!
    Id be very gratefull if any of you could help! Thanks!

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load 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 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.
    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 Steps 1 and 2.

    ^Hi.  yesterday, after trying to study on my iphone 4, i accidentally clicked okay on something that poped up while flipping through notecards.  it told me that it was "updating", i had my phone updated to ios7 but not 7.0.2..  i tried to shut if off to see if it would stop the update, because i didnt want it to do that.  after a few minutes i turned it back on and it was still updating.  it then shut off and a screen poped up telling me to plug my phone into iturnes.  itunes recognized my phone and said it was in recovery mode and i would have to restore it.  i have tried to restore it three times and nothing has happened.  it will go all the way through the restore process, say it is finished, and then nothing will happen.  my phone will not stay in DFU mode, i have tried for 20 minutes to get it to.  i have even uninstalled and reinstalled itunes.  i dont know what to do and i have been without a phone for alomost 24 hours.  how do i get my phone back to normal?  can i fix it or could at&t replace it?  or do i have to take it to an apple store? Please help me.

    Has your phone been jailbroken in the past? If yes, this could be a reason for not being able to finish the restore process.
    If not, did you try to restore it on a different computer?

  • Safari + Silverlight + Full screen = MBP suddenly shuts off and restarts

    In the past few weeks, my MacBook Pro has unexpectedly shut off and then started back up three times. Each time it happened while I was watching full-screen Silverlight video in Safari (4.0.3) — twice on the Netflix website and once on the NBC Sports website.
    The first time I had been watching the video for several minutes before it happened; I switched to a different computer to finish my movie.
    The second time it happened as soon as I switched into full-screen. I watched the rest of the game in a window (i.e., not full-screen) without incident.
    The third time happened after seven minutes of full-screen video. I switched over to Camino (1.6.9) and was able to watch the rest of my movie in full-screen without incident.
    I've watched full-screen video in Safari many times before without problems, but the last three incidents have occurred the last three times I've done it (i.e., it now seems to be happening every time).
    Each time, my MBP was connected to power, so I don't think it's a battery issue. Could it be an overheating issue? The fact that I was running the same software combination each time suggests to me that it's a software problem, but the symptom suggests hardware. Thoughts?

    Update, As of today, they STILL haven't shipped me a new battery, they claim they are within their 5-7 business days limit still and that it might/should ship tomorrow.
    I went into an Apple Moron Bar today and inquired about swapping one out in the store (they had plenty in stock) because the Applecare tech I spoke to said that it might be a faster option. The Apple 'tech' (seriously, he might be really good at ipods, but I doubt he knows how to turn on anything worth more than $300 with an apple logo on it, much less troubleshoot it) claimed he didn't have any batteries in stock.
    "Excuse me, but you have a shelf full of them over there"
    "I don't have any for replacement, you are welcome to buy another though or I can order one from Apple"
    Great, so my MacDesk Pro is still without battery power.

  • My screen shut off but my iPhone is still on. What can I do?

    My screen shut off but my iPhone is still on. What can I do?????????

    Try a Restart by pressing the sleep/lock button until you see the slider.  Slide to power off.  Restart by pressing the sleep/lock button until you see the Apple logo.
    Try a Reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider if, it comes up. Takes about 5-15 secs of button holding and you won't lose any data or settings.

    My 1st generation Time Capsule/2007 keeps shutting off and disconnecting from internet?  What could be the problem?  How long do the Time Capsules usually last?

    That it is still working is miraclous.. most have died.. lots started flaking out at 18months to 2years..
    See deadtimecapsule.org
    The few that remained now seem to have reached EOL.. you can repair if you have some skills.. fairly cheaply.
    But it is well and truly time to replace.
