Replaced Left Fan now fan wont turn on

I have a macbook pro 15'' Early 2009 (2.66 GHZ). I am running Lion (10.7.5) I recently replaced the left fan in my computer due to it not working well. My computer seems to run fine, however, the left fan will not turn on.  I double checked to make sure the connection was good, and it was. The fan was brand new, and did not seem to be damaged, and I cannot figure out what is wrong with it. I am out of my warranty, and would prefer to avoid taking my computer in to the apple store if possible, so any suggestions would be appreciated.

I tried doing the thing to reset the SMC, there wasn't anything to signal that it reset, but I followed the instructions so Im assuming it worked.  didnt change anything.  Um for the logic board that is a possibility, but the old fan was on, it was just gradually running slower and slower until it was pointless to even use it as it would sometimes have trouble starting.  If I push it with my finger it doesn't spin very long, I think it might just need oiling, but it might be easier to just get this new fan working, if possible.  This new fan isn't running at all, or making any attempt to run.  Is there some way to tell if the logic board is working properly?

  • My iPhone shuts down with certain apps and says dead Batt. with plenty left. Now it wont turn on after starting up and turning off many times

    I got my Dads old iPhone 3GS for Christmas and reset it to its factory settings. It had this problem with my Dad to, thats why he got a new phone. It was claiming that the battery was dead when I opened certain apps eventhough it had plenty of battery, It made me charge it and then said it was plenty charged. Why? That happened multiple times. That's what happened to my Dad as well. This however, is me only. O.K. so, the other day, it did it's battery dead shutdown thing, so I plugged it in, but it kept starting up, then shutting down again, starting up, and shutting down again. Now I've left it on the charger for about a days, it's not on the charger now, and it won't turn on. Help!!!!!!

    Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).  Try each of these in order until the issue is resolved.
    If the issue persists, take the device to Apple for evaluation and possible replacement.

  • Used wrong charger with ipod classic, now it wont turn on, displays the low battery icon even though its connected to the wright adapter

    used wrong charger with ipod classic, now it wont turn on, displays the low battery icon even though its connected to the wright adapter.
    Can anyone help ?
    please?

    WHow long have you left it to charge?  Have you tried resetting it after a short period of time to see if that can help jumpstart the charging process? To do this, press and hold both the Select/Center and Menu buttons together long enough for the Apple logo to appear.

  • I recently updated my phone to IOS 8.0.2 and now it wont turn on it just says to connect to itunes and when i do the only option it gives me is to restore iphone. It says it will delete all my media but i didn't do a back up what should i do?

    I recently updated my iphone 5 to IOS 8.0.2 and now it wont turn on it just says to connect to itunes and when i do the only option it gives me is to restore iphone because it is in "recovery mode". It says it will delete all my media but i didn't do a back up and i don't want to lose my photos, what should i do? (I never used iCloud to back them up either).

    If it's in recovery mode, the data is already gone. Why did you never back up your important data?

    Given the state your device is in you have already erased your old stuff. You have an image on the screen that says, "Connect to iTunes." That's what the image means. So you will need iTunes on your computer.

    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode

    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - Try on another computer          
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

    Hello there, RFJA2211.
    The following Knowledge Base article offers up some great troubleshooting steps for unexpected power off of your iOS device:
    iPhone: Hardware troubleshooting
    http://support.apple.com/kb/ts2802
    Will not turn on, will not turn on unless connected to power, or unexpected power off
    Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
    Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
    Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
    After at least 30 minutes, if:
    The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
    The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
    Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
    If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
    If the display turns on, go to step 4.
    If the display remains black, go to next step.
    Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
    If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
    Thanks for reaching out to Apple Support Communities.
    Cheers,
