There's a few things my MB does that kinda pisses me off. It's a Sept 06 model, 2GHz Intel Core Duo. Failure to shutdown; I generally leave my MB on, putting it to sleep when I don't use it. But sometimes when I need to shutdown, restart, or the Software Update needs to restart, either it wont do anything and give me an error, or the menubar, desktop icons dissapear, but the dock doesnt. And it just sits there, and I have to force it to shutdown. Goes to black screen after logging in from sleep; Sometimes when I wake it up from sleep, and enter the login password, it goes to the desktop and then quickly switches back to black screen with only the mouse visable. I can't do anything, and I have to close the lid and open it again to get the login screen. With that, I have it set so when i move the mouse to the bottom-right corner the screensaver activates, and when this happens i can no longer activate it. Battery dies at 20-30%; Even though the last time I used it it went to 12% fine, still everyone should know about this problem. I would take it back to Apple but I know what they're going to say, so is there anyway to fix this on my own?
