Hello, When finished, I normally put my mac into standby mode instead of turning the power off. Last night, I did the same. When I tried to power on today it seems like my mac is working (the buttons beep when pressed and hear the hardrive), however, the screen is blank (never turned on). I BELIEVE if I can actually turn my mac off and on again it may fix it, however, I have already tried taking the battery out and putting back in to no avail and I think everytime I try by pressing the power button it goes into standby mode. Is there a way i can force my mac to turn off instead of going into stanby mode by pressing certain buttons since I can't see the screen? Or any other recommendations? Thanks in advance for your help!
