When I close the lid, it used to go into standby and the little orange light would blink to let me know its in standby mode. Now if I closed the lid, the monitor, drive, etc. will turn off but the orange light won't come on and the fan still blows like its on full power mode. Its like its going into a half assed standby mode. The worst part is if I open the lid and try to come back into normal mode, I can't. I end up having to hold down the power button and reboot. Anyone know whats wrong?
