I have purchased a new Toshiba A505-S6033 PSAT9U-006002 laptop which is installed with windows 7. I have changed the settings in such a way that when the system remains idle for 10 minutes it goes to the sleep mode. But from last two days i had to force fully shut down the laptop since Satellite A505-S6033 wont awake from sleep. After forcefully shutting it down i have to restart it again. please help me how to go about this problem.
