MacBook pro - only wakes up or restarts from disc
Can not wake up my MacBook pro once it goes to sleep, or restart it without the installation disc. The apple logo appears but then the screen goes white. It DOES restart if I insert the original OS X installation disc. The fan is running really fast and the computer gets very hot..
