Q: Can't run hardware test to resolve charger light issue.

I've got a macbook pro 17" early 2009 model w 2.93 processor (5,2) with mountain lion (osX 10.8.2) installed on it.

 

My chargers work but the light cuts in and out, regarless of which charger I use.  I want to run the Apple Hardware Test.

 

I've tried option-D on start, which I'm told won't work on this model.  I've also tried D on start.  In both cases it just boots to the login screen.

 

I tried downloading the Apple Hardware Test image for this model from Apple and after converting the image discover it has folders, but there are no files in those folders (yes I turned on hidden file viewing)

 

How does one run the hardware test on MBP 5,2 once mountain lion is installed.

    Boot from your original System Install or Applications DVD - whichever has the words "AHT version xxxx" printed on it. There is no other way to run AHT on your Mac.

     

    I know of no such downloadable image file.

    Wow, I appreciate the quick reply.

     

    After upgrading to lion with a download and mountain lion with a download I didn't keep my original DVD.

     

      Is there a place I can buy the original DVD?

    The original installation DVDs are indispensable for many reasons and can be a challenge to replace. Contact Apple. Explaining to them exactly what you need is the tough part. They will charge a nominal fee for replacement DVDs.

     

    You will need your MBP's serial number - it is printed on the rear case near the display hinge.

     

    In the meantime try an SMC reset. It may fix the problem.

     

    Resetting the SMC on Mac portables with a battery you can remove

      1. Shut down the computer.
      2. Disconnect the MagSafe power adapter from the computer, if it's connected.
      3. Remove the battery (to remove the battery - click here: MacBook or MacBook Pro).
      4. Press and hold the power button for 5 seconds.
      5. Release the power button.
      6. Reconnect the battery and MagSafe power adapter.
      7. Press the power button to turn on the computer.
    Still having problems? Replace steps 6 and 7 with the following:

     

      6.  Reconnect MagSafe power adapter.

      7.  Press the power button to turn on the computer,

      8.  Then reconnect the battery.

    Thanks,  I'll contact Apple.

     

    I followed the instructions to reset the SMC for unibody machines like mine. I don't feel comfortable cracking the case to remove the battery.

     

    I'll just wait for apple to send me a replacement disk.

     

    Thanks so much for your help.

    Sorry, I posted the wrong instructions for your MBP. You probably already followed the correct one but here it is:

     

    Resetting the SMC on portables with a battery you should not remove on your own

    1. Shut down the computer.
    2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    4. Release all the keys and the power button at the same time.
    5. Press the power button to turn on the computer.
