Greetings to all,
I have recently discovered that when I put my computer to sleep, it does not wake up! It also begins making a whirling, rather loud fan sound occasionally. If I turn it off, and start it up again, the matter is resolved. However, the sleep situation prevails. When I press any button to turn it on, it says "No Signal". I press a few buttons, and after a while it eventually turns on. Sorry for the long story. Any advice would be greatly appreciated. Sincerely, Tanni
