Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. Try that.
Still having problems? Replace steps 6 and 7 with the following:
- Shut down the computer.
- Disconnect the MagSafe power adapter from the computer, if it's connected.
- Remove the battery (to remove the battery - click here: MacBook or MacBook Pro).
- Press and hold the power button for 5 seconds.
- Release the power button.
- Reconnect the battery and MagSafe power adapter.
- Press the power button to turn on the computer.
6. Reconnect MagSafe power adapter.
7. Press the power button to turn on the computer,
8. Then reconnect the battery.
John thanks for the help. I had to go to the 2nd step but when I reconnected the battery while it was plugged in and on it shut the computer off immediately. I restarted it just plugged in, shut it down, installed the battery, plugged it in, and it wouldn't restart. So I am thinking the battery is bad?
Do you know a ventor for batteries?
Here you go:
There are plenty of aftermarket battery vendors. I do not recommend them since I have found Apple batteries last the longest.
If you want to consider another source here is one:
You can get a new third party battery fairly cheap on eBay. Every MacBook from 2006 through Mid 2009 except the Late 2008 Aluminum Unibody and the Late 2009 and 2010 White Unibodies use the same A1185 battery.
Or for $129 from The Apple Store http://store.apple.com/us/product/MA566LL/A?mco=MTY3ODQ5OTY
