ok...force quit is: apple+opt+esc right? ok...force reboot is: apple+option+shift+power button right? well sometimes my machine locks and stays locked....what should i do? On PC's you can just hold in the power button for a bit, and it will "hard reboot" and allow you to restart it...scan disk...then use again.... i cant figure out how to do that on the wallstreet....ive been pulling the battery out. Actually, when i do that....it wont restart again until i put the battery back (duh!) and then plug in the wall charger......THEN it will turn on and act normally.... but if i pull the batt and replace it, without plugging it into the wall, it wont turn on again.....normal?
