Fast blinking sleep indicator, computer shuts self down, trouble rebooting

And I've gotten columns of horizontal lines (1" long, 1/8" tall) across the screen that locks system. I also get the kernl panic screen that tells me to reboot. When computer sleeps, it sometimes goes from the slow pulse to a fast blink where I cannot restart the computer without doing a hard-boot. Sometimes, the computer just shuts down.
Help?

Yikes! It sounds like you have several problems. I might suggest you visit a local Apple store and make an appointment with the Mac Genius to have a look at your MacBook. I've never heard of a fast-blinking sleep light when the computer is already turned on. A blinking sleep light may be an indication (at startup) that you have a RAM problem. Have you added or changed the RAM that came with your MacBook?

  • Computer shuts itself down after about 30 seconds

    Ive had my computer since 2008 and it has ran perfectly fine untill a few moths ago where the fan just started making loud noises and just generally over working even when the computer isnt hot. Suddenly a month or two ago it started shutting itself down after about 10 minutes and it just got progressivly worse and it wont even get too the start up screen. Is there any idea on what causes this or how i can fix it because I really dont have the money too purchase a new computer and it would save ALOT of hassle too get it repaired,
    Thanks, Jack

    This is usually a sign that your headphones are not plugged all the way in.  Make sure you cannot see any silver still showing from the headphone's plug.  It may require a little extra force to get the headphones to become fully inserted.  You should hear a sort of clicking noise indicating that they have been fully seated.
    Also check the headphone port from a damage or debris.

  • Macbook Pro Shuts Self Down

    I recently upgraded to a pro from a older macbook (the small 13 inch black one), and there seems to be this reccuring problem. I'll leave for a hour or so, allow the computer to go to sleep etc, with no applications open I'm aware of. I'll come back and sometimes it will have just shut itself down with no prior warning or such, like there wasn't any battery left. It's only recently started to do this too. It usually tells me the laptop shut down due to an issue... etc.
    Is this fixable by me... or do I need to take it in?

    I have the same thing happening with a new macbook I bought my wife and I called apple today and after going back and forth between apple care and apple customer service they are shipping me out a new replacement macbook as it is less than 30 days since I bought it. I am waiting for their email with the Fed ex info so I can send this one back and then they will send out the new one.
    If it is still in warranty I suggest you call Apple customer service and let them know how bad it is and insist on a new one!
    This one also reboots at the slightest movement and it took me several tries to finally log in on it tonight to delete all the user accounts before I send it back!
    Hopefully the replacement one is glitch free!

  • Sleep Indicator Problem when Powering Down MacBook

    When I power down my MacBook Pro and close the laptop, the sleep indicator light comes on. It does not pulse like it does when the machine is asleep, it stays constant. Then when powering the computer back on, the power button is unresponsive and needs to be held for a moment in order to turn the computer back on.
    I tried unplugging the computer while I was away from it, and after a couple of hours the sleep indicator was off and the battery was completely drained. After plugging the computer back in, it booted up like normal.
    I usually turn the computer on when I get home from work, and turn it off before I leave for work in the morning. So, the computer is usually off for about 10 hours a day. Also, I usually cycle the battery once or twice a week to keep it from dyeing on me. I have owned the computer now for about two years and keep all the software and security packages up to date. If anyone has input, it would be much appreciated. Thanks.

    The LED light comes on only after I close my laptop, it doesn't turn on until the top is closed. I always close the laptop after I turn it off though, I haven't tried leaving it open after turning it off. And I usually give it about a minute or two to completly shutdown before I close it up for awhile. By holding down the power button to turn the computer on, is that considered a forced shutdown?

  • Computer keeps shuting down and reboot after 10 minutes

    Pavillion PC p6107
    After 2 years just keeps shuting down and rebooting after 10 minutes. Checked fans and dust, not the issue. All scans HP, Norton etc indicate nothing?

    Hi:
    I would yank all the memory but one chip and test each one in the primary memory slot.
    Maybe one of your memory modules is flaky. Not completely bad memory to me is worse than a stick that just dies and won't let your PC boot up at all.
    Could be a power supply on its way out too.

  • Computer shuts automatically down

    Recently... My when my MacBook pro has a low battery it will immedielty shut down without warning. It no longer displays a warning and/or goes into sleep mode. Does anyone else have this problem?

    Hi everyone,
    I bought one of the first Macbook Pro 15" 1.83Ghz models and after a few months started having Random Shutdown Syndrom. This is when everyone with Macbook was experiencing this problem. I took it in and the Mac store replaced my "bulging" battery and the logic board, but not the heat sink.
    Now, a month later, it is happening again, only when running on battery. I have all the latest updates and upgrades, which means that it is not a battery nor a logic board problem, leaving the heat sink. I wish there were a real, final answer, but it seems like it's going back and forth and no one really knows what the final fix is.
    Other than this, I'm "still" a Mac fan.

  • Just installed memory, fast blinking sleep light

    Installed Ram on my MacBook. Now I have blank screen and my sleep light is rapidly blinking?

    Count me in on this question - I have a 2006 Macbook - trying to upgrade 1 gb ram (2 X 512) to 4 bg (2x2) - I got the PC2-5300 667 DDR2 2x2 GB kit from Kingston, and had the same issues. The only thing that will work is the original ram in the notebook now.
    The reason I'm trying to do this is to upgrade to Lion to be able to switch over to the freaking iCloud soon...
    Any advice???

  • Suddenly, touching the iPad screen...I get no response.  What do I do?  I cant even shut it down to reboot it!

    Suddenly, the 3rd generation iPad will not recognize my touch.  I cant slide the screen, cant open an app, etc!  I think this happened once before and I have no idea what I did to fix it!  Help!

    First thing to try is a reboot of your iPad. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider until the Apple logo appears. Let go of the buttons and let the iPad restart. See if that fixes your problem.

  • Which is better for a MacBook, shutting it down or putting it to sleep?

    I been researching the question for a while now and have not found an informed answer yet:
    Is it "better" for my MacBook to be shut down over periods of inactivity or to be put to sleep? (with a period of inactivity being 6 hours or more)
    Which option saves more battery life (if either)?
    Which option saves the life of my MacBook (if either)?
    -Thanks.

    The Macbook, Macbook Pro and other Apple portable systems are designed for a very robust uptime. You shouldn't need to reboot your machine except for battery maintenance (drain the battery about once a month), and when applications or hardware components misbehave. With that thought in mind, I would put the computer to sleep rather than shut it down--the exception might be when the period of inactivity runs to several days or more.

  • My computer keeps shutting itself down

    at around 2:40AM this mourning my computer shut itself down again
    this has happend several times
    i had it running minimal power management  800mhz and all that
    i have a 650watt power supply was cheap should still work dont really wanna open my case for the numbers, anyways it just sits there blinking the power light as if the power shut off on me or i tripped a breaker but my UPS wasnt goin off
    i have corsair ram that doesnt have a problem with my system it was corsair value select pc3200
    5 hard drives currently in the system
    7 fans
    my signature will tell the rest, anyone have a clue what could be goin on

    Random reboots are often indicators of memory instability.  I don't think overheating or power supply failure are to blame (although you should post the current over your PSU rails in your signature ... look on the side of your PSU).  However, due to the fact that you're running PC2700 RAM (DDR400 RAM often causes more instability than slower variants, such as your DDR333) you should perform some tests before we can be sure the RAM is to blame.
    First, run Prime95's blend test.  Download the program, run it, then goto Advanced->Password and enter "9876" (without the quotes).  Then goto Advanced->Priority, and set it to 10.  Now select Options->Torture Test and select the "Blend" option.  Run the program uninterrupted and observe the results.  If your memory is unstable, it should result in an error within minutes (~10 minutes), although you could run it for longer if you feel so inclined.
    Another memory check (which checks for physical errors in the RAM itself) is Memtest86.  You must create a bootable CD or floppy and then boot into the program in order to scan your memory.  It may seem like a pain, but in-Windows memory checks often report false positives because of background Operating System components messing with their processes.  Memtest used to have issues with 64 bit boards, but apparently that issue has been resolved.
    If you find out that it is your memory that is causing your reboots, there are many steps you can take to eliminate the instability.

  • Booting problem - computer shuts down during booting

    I have run into a problem this morning after trying to download Yosemite. I have a Mid-2007 C2D iMac, that was running Mavericks very well this morning.
    I tried to download the Yosemite update - but it kept getting an error message as it was trying to download. The computer became unresponsive, so I shut it down to try and reboot.
    Now when I start my computer, I get a grey screen, with the Apple logo, then after a few seconds a spinning icon underneath, and then a few seconds under that a status bar. Once the status bar gets to about 25%, it goes away, and then the computer shuts itself down. Any ideas? Is it trying to install Yosemite, but can't find the files?
    Any thoughts would be appreciated - thanks!

    Hey bburkava,
    Thanks for the question. I understand that you are experiencing issues with your iMac not loading up past the Apple Logo and spinning gear. The following resource may provide a solution:

  • Cooling Fan Error Message & Computer Shut Down

    Hello,
    I have a 2 1/2 Satellite running W7 and recently started having a problem, receiving a Cooling System error message which tells me to shut down the computer immediately.  I did and left it off to cool, then started it up again.  Less than 5 minutes later, same message and the computer shut itself down.  The fan starts normally, then becomes burdened, then stops.  Is this actually fan related or hard drive related?

    Hello Peter,
    I already have the new BIOS you sent me.  The problem persists.  Toshiba has no Authorized Service for computers where I live (Brazil) as far as I can see on their site, which I can't understand since it is a global company.  So, I can not use my business computer now.  Apparently, I either have to ship it to the States (which will cost me more than the computer is worth, and I'm better off buying a new one of a brand that takes care of its customers globally), or I have to try and find someone here who thinks they might be able to discover the problem and fix it.  Any suggestions?

  • I use my I mac every day what is the best way to shut it down?

    I use my imac every day. What is the best way to shut it down? Do I let it sleep or manually shut it down?

    That can start a lot of debate...some say shutdown, others sleep.  I am in the same camp as Niel...let it sleep.  I only shutdown if I am going to be away from the computer for more than a few days.  Sleeping keeps a constant temperature and does not thermal cycle like shutdown and startup.

  • P55-GD85 shuts down then reboots on its own?

    I have just set up a new P55-GD85, when I shut it down, it reboots on its own?
    I would appreciate ideas on how to fix this do do a normal shutdown

    Did you try disabling every option in the "Wake Up Event Setup"? 
    I just checked the Changelog for the latest BETA Releases for your board.  The latest BETA Version is A7585IMS.132 [v1.3b2] and among other things it includes the following fixes that seem to address the problem you are experiencing:
    Quote
    - Fixed WOL still work after disable LAN controller.
    - Fix after use LAN (on PCIE slot) wakup S1,system can't shut down from OS issue.
    For you, this means good news:  Your problem is already known and was, at it looks, already fixed.  All you have to do right now is to contact MSI Technical Support and ask them to provide you with that BIOS Release.
    http://support.msi.com/
    Once you have the BIOS, ensure that your system is stable and then use the >>Use the MSI HQ Forum USB flasher<< to flash it (please avoid M-Flash or Windows based method for minimum risk).
