Macbook won't boot up after smc reset

So here goes, my macbook which is a late 2011 model had a trackpad problem which it would move everywhere, open & close softwares, do multitouch gesture on it's own that I couldn't use my macbook anymore. I tried everything, change trackpad setting, language, wipe my trackpad really clean, PRAM reset. Nothing helped. So lastly I tried SMC reset & when it was booting, my macbook was stuck at booting grey screen. No progress at all after an hour. So I turned it of thinking the reset was unsuccessful. Then I tried turning it on again, the grey screen appeared but with the apple logo only & no loading wheel. I waited & about a few minutes later, a folder icon with a question mark on it appeared in place of the apple logo. Then a 'no symbol' appeared a few seconds later. And then the apple logo returned. The cycle repeated one more before macbook turned off on its own. Help please?

Try a PRAM reset. If that doesnt work, reboot back into that same recovery partition and reinstall the OS, you can use either your old disk or an internet recovery. You will most likely loose your data however so you may want to try and back it up. You can do so through another Mac computer with either an ethernet/firewire cable and an app called "Migration Assistant".
Here are a couple articles that may help:

  • Macbook Air won't turn on after SMC reset

    Hello,
    The fan on my macbook air had suddenly started becoming very loud intermittently even with no apps running. I tried restarting the computer several times, but the problem persisted for about a week. Looking online, I found an SMC reset might solve the problem. However, after doing the reset, my Macbook now will not turn on at all. There is no startup chime or lights when pressing the startup button. The only thing that happens when I press the power button is that the light on the adapter turns from orange to green for second before turning back to orange.
    I have an appointment with the Genius Bar tomorrow, but would like to seen if anyone has any suggestions. Thank You

    Try the SMC again:

  • Macbook Air Boot failure after SMC reset. HELP.

    Hi all.
    So, my brand new macbook air may have encountered some water or something, i seriously dont know, but i booted it up this morning and the fan was rather loud, like seriously loud, so i check out activity monitor and the CPU usage was a solid 80% consistently even with no applications running. So i go for an SMC reset, and as i do the reset the charger falls out, literally (useless magnets), anyway i go to turn it on, and all that happens is the LED on the magsafe goes from orange to green then back to orange with no sound, no "tone", no nothing: dead silence.
    Im a little concerned to take it in to an apple store as this alleged encounter with liquid that i was told about by my brother makes me fear that the LCI's will make it out of warranty.
    I mean it was working fine about ten minutes ago and so surely some wierd SMC hitch cant have completely mucked up the whole thing?
    Its the latest model (as in early 2014).
    Thanks in advance

  • 11" MacBook Air won't start even after SMC reset attempt

    I press the power button on my Air and the Apple sound chimes, a dimmed grey-black screen appears and nothing else.  I have combed through the communities and the suggestion was to do a SMC reset. I followed the instructions exactly and nothing changed.  I initially plugged into my Thunderbolt monitor and ultimately plugged into power with the standard MagSafe cord. Neither changed the outcome.  I have had this Air since November 2014.
    One of my questions about the SMC reset was how could the device recognize actions while the computer is powered off?
    Please help me!
    11" MacBook Air, OS X Yosemite (10.10.2)
    Resetting the SMC on portables with a battery you should not remove on your own
    Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer.
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

    You have to take the computer to the Apple store to have it checked out.

  • Macbook pro not turning on after SMC reset. I have the following problem. Yesterday I noticed that my mbp 2011does not sleep when closing the screen. smc due loud fan and an X on battery symbol

    Yesterday I noticed that my mbp 2011 dos not sleep when closing the screen cover. Today I Turner my laptop in. However the fan was working loudly and stayed loud. After Start I noticed an X on Battery symbol. Clicking on it, it showed 'no battery.' I found out that a potential solution for this problem was SMC reset. I also noticed that the leds on magsafe was not lightning. Despite this I tried to execute the smc reset as described on apple support site. Switching off, plugin the magsafe connector, pushed the buttons shift + alt+ ctrl + power. Then i pushed the power button, but my mbp is not turning on. I pushed several times on the power button but nothing works. The magsafe is also dark meaning the leds not lightning. Can anyone here help me on this ?

    Problem solved by my own. But do not how :) magsafe again working and the laptop tooo

  • Please Help! Macbook won't boot up after attempted Leopard install (Wont bo

    Ok so I'll go through EXACTLY what has happened to my laptop in the past day.. please note that the laptop was NEVER moved from the desk while this has all happened. Also a couple other things you should know.. I had Applecare, but 6 months ago when i sent it in to replace the harddrive -- they said they found some water damage, and it would cost $700 to replace... so i just put in the harddrive myself for $50, and it has worked fine since... So I'm pretty sure I can't turn to Applecare anymore...
    Alright...
    Yesterday
    One of my memory sticks went bad on me... (i had 2- 1gig sticks.) I took the bad one out, and the computer seemed to run fine on the single stick of memory.
    Last night
    I started to install leopard as an update over 10.4, seemed to work fine, though it was slow -- and finally i got to the leopard installation complete thing (please reboot the computer)... so I did...
    It starts loading up... shows the mac symbol with the loading circle thing... but wait, Oh ****, i was probally was supposed to take out the cd... So i turn off the macbook by holding down the power button... and I eject the cd, and then try to start it up...
    Not loading... ****.
    So after some mulling i decide, alright -- i'll reinstall again...
    I boot to the cd drive, choose my options, start the install, and go to sleep..
    This Morning
    I wake up.. the install hasn't moved at all... It's still at the same place where i left it..
    ****... so again I manually shut it off, and try and restart to boot from the CD again..
    NO GO....
    If I hold down C to boot from DVD
    The computer attempts to read the disk.. CD drive seems to power down.. then try again.. Then it ejects the cd, and goes to the Apple logo with the spinning circle, but never loads. I've tried it with My old 10.4 disk, and the new leopard disk. Same result on both. neither disk seems scratched either.
    If I just boot up regular
    It goes to the apple logo with spinning circle.
    SOOOO...
    I tried resetting the PMU, and PRAM
    Is it likely that it is my superdrive gone bad, at a horrible time? If so I guess i'll just buy one on eBay and replace it myself. Is there any way to test it?
    Could there by another problem wrong with it?
    Please help me troubleshoot this! I'd be very appreciative -- I'm a poor college Computer science student that needs his computer to work for his classes.
    Thanks All!

    Could there by another problem wrong with it?
    Yes. You need the two RAM modules, or at the very least the remaining one RAM module must be for sure securely seated. If not securely seated with only one module, the result is as you've seen.
    i was probally was supposed to take out the cd...
    No, not necessary. After that, the very delayed loading was totally normal, sounds as if you were just impatient.

    Oh, and check the AppleCare agreement, as to the best of my recollection, you can should be able to get a refund, pro-rated for time left.
    Check how full your hard drive is now. I'm not clear if you've yet erased your HD or how many systems you've installed - if not erased perhaps it's full up.
    A PRAM reset should allow you to boot from the install disc, access the Install Discs's System Profiler, and see what things look like. Also, you should be able to boot to the Apple Hardware Test - while you do need a working optical drive to do so, you don't need any hard drive at all, and it doesn't sound like either one has been lost.

  • Macbook won't boot up anymore after trying to reformat

    So my White Macbook won't boot up anymore after trying to reformat. While trying to install a fresh copy of Snow Leopard, the Macbook just froze and I had to reset. Now, while trying to boot it up, it hangs at a white screen with a folder with a question mark.
    My install disk is still in there, so when I try to boot up while holding C, nothing happens. It either goes to the folder with a question mark or the screen stays white. So after that I tried holding option to go to the drives nothing happens. I just see a white screen and a cursor.
    I tried resetting PRAM and tried booting in safe mode and everything but to no avail. Everything results in just a white screen or just a folder with a question mark.
    Can I do anything before I have to bring it to the Apple Store? The optical drive should work because before I reformatted it, I could see that the disk was in the drive because the icon was in the upper right.

    it hangs at a white screen with a folder with a question mark
    Startup your Mac while holding down the Option key. That should prompt the Startup Manager window where you can select the startup disk.
    A flashing question mark appears when you start your Mac

  • MacBook won't boot when iPod is connected

    I have the same problem as described here :
    http://discussions.apple.com/message.jspa?messageID=4112865
    My MacBook won't boot if my iPod 5G is connected to the USB port.
    If I unplug it, it will boot normally.
    Does anyone know what could cause that ?

    <When iPod is plugged in at startup, the MacBook does not startup; unplugging iPod lets it startup.
    yes, it seems that the kernel is not loading
    <After resetting the iPod and BEFORE synching it, there is no problem. Any type of synching seems <to make this problem recur.
    only syncing music make the problem occur.
    the other syncing works ok
    <Even if iPod is connected directly to Mac and it is the only USB device connected, the problem still <occurs.
    yes
    <The iPod and MacBook work fine if iPod is connected after startup.
    Yes
    <If the iPod is set to NOT mount to the desktop, the problem with startup does not occur.
    Yes, but there are some problems in the boot/halt process.
    something like "killing all" fails and unmounting /home fails (45) blabla...
    and the stopping process takes very very long, about 2 minutes.

  • My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard (via my MacBookPro), either from the HD or DVD drive.  Can't get it to run Hardware Test.  Disk Utility says disk OK - files are there. What can I do?

    My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard.   I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host.  But after numerous attempts I still can't get it to boot either from the HD or DVD drive. I just get the white screen after the wheel stops spinning.  I can't get it to run Hardware Test - just get the white screen.  If I use Disk Utility via my MBP it says the disk appears OK. All the Snow Leopad files appear to have been installed. What can I do?

    Perhaps you installed the wrong version OS X onto the iMac, you can't use the disk from another Mac.
    clean the disk.
    If it's not working then use this method to create a bootable 10.6 USB from the iMac machine specific 10.6 disk or the 10.6.3 retail disk on your other Mac, use it to boot the iMac with.

  • Macbook will not boot up after running Software Update

    My MacBook will not boot up after running Software Update (Security update + Java?) earlier today. I have only the gray start up screen + Apple logo + gear wheel constantly rotating. I have tried restarts several times and tried to start up from my original system DVD - this makes no difference.
    I called Apple support, tried resetting the power and PRAM - still no difference. He had no knowledge of other problems reported; although I note recent post may have same issue.
    I cannot get an appointment at my Apple Store before Monday.
    Any suggestions?

    Still no success. When I hold down the option key when powering up I get the hard disk icon plus arrowhead (only). When clicking the arrowhead it goes to the gray screen + apple logo+ rotating gearwheel.
    This happens both with DVD in slot and without DVD. the DVD image is not coming up on screen. When I start up without DVD the hard disk icon appears promptly. When I start with DVD in the DVD is spinning for a short period before the hard disk icon appears. On clicking the arrowhead to hard disk icon the DVD spins again for a while then stops. Apart from the DVD spinning, both situations result in gray screen + apple logo+ rotating gearwheel.

  • Macbook won't boot up - grey screen only

    Hi,
    I have a core duo MacBook from summer 2007.
    All of a sudden the MacBook won't boot up. The battery is fully charged and AC adapter plugged in (same symptoms if not plugged in). The following occurs upon pressing the power button:
    1) Start-up chime sounds
    2) Can hear hard drive and fans start up
    3) Screen turns grey
    4) Nothing happens (screen still grey)
    Thoughts? I tried resetting PRAM and PMU with no changes.

    I have the same problem, just the grey screen and tried
    - resetting PRAM (second chime, so this should be OK)
    - Safe Mode (just the same)
    and pressing Option (or C) to choose the Mac OS X Install Disc gives me the wonderful cursor which can be moved by moving the mouse. No harddisk and even no Install DVD are displayed on the screen.
    Also The Apple Hardware Test (by pressing D) doesn't get further than the, now familiar, grey screen.
    I pressed the keys with different keyboards, with the original white keyboard and with the aluminium keyboard.
    As I've tried everything, I think there's something seriously wrong. Does anybody have some last tips that I can try?

  • Oh, shoot! My MacBook won't boot! Silver screen is all I see!

    Oh, shoot! My MacBook won't boot! Silver screen is all I see

    Try a PRAM reset:
    Shut down your Mac.
    Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.
    Any unusual noises coming from it?    

  • Macbook won't boot properly.

    Macbook won't boot. When turned on, it starts clicking; after a while, I get a gray screen with a blinking folder in the middle that has a question mark on it.  After a minute or two, it shuts off.

    That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the Operating System data on the hard drive is somehow corrupted.
    Put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
    Or if you are running 10.7 Lion, boot from the recovery partition (Command +R on boot) and use Disk Utility to repair your OS 10.7 partition.
    When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
    If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
    If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.
