Q: My (2008) macbook pro, running 10.5.8 runs for about 30 seconds and then goes into deep sleep mode.  After significant difficulty awakening, it runs for 30 seconds and....start repeating here.  It did this once before about a year ago.

.....and then goes into deep sleep mode.  When it (finally) awakens....it runs for about 30 seconds and.....start repeating here.

 

And yes, I've shut dwn and restarted multiple times, rebooted in terminal mode and run fsck, rebooted and reset the parameter ram, yadda-yadda......

 

 

Anybdy got any ideas?

    Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. Read all the steps.


    Before Resetting the SMC

     

    Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.

     

    1. Press Command + Option + Escape to force quit any application that is not responding.
    2. Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
    3. Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
    4. Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.

     

     

    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:


    1. Reconnect just the MagSafe power adapter.
    2. Press the power button to turn on the computer,
    3. Then reconnect the battery.

     

    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 it's 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. The power adapter indicator light may cycle off / on once.
    4. Release all the keys and the power button at the same time.
    5. Press the power button to turn on the computer.
