I have a late 2008 Aluminum body macbook that they discontinued because it was basically the same as the pro only 200 dollars cheaper . The problem I'm having is that the computer won't stay asleep. I can shut the lid and it will sleep for a few seconds and then the apple lights up and the hard drive makes noises. it will then go back to sleep, and then fire back up and repeat. I also tried using the sleep feature in the apple menu and left the lid open. This also fires the computer back up. Also, when I shut the computer down- lid closed or open, It turns itself on after a few seconds. I tried resetting the SMC using this guide that the Apple care # automated system gave me: http://support.apple.com/kb/HT3964 (of course this WOULD be the only apple product i dont have apple care on) This is not a HUGE deal, but it is nonetheless annoying, and I've only had this for two years, so I'm not ready to replace. The waking is understandably obliterating my battery life. I did notice one way to get the computer to STAY shut down. If i shut down the computer and then hurry and take the battery out and put the battery back in, it will stay shut down. BUT i shouldnt have to do this every time just in order to save battery. HELP!
