My laptop, a Toshiba Satellite U40, has the following problem. If it enters sleep, when I close the lid, it won't wake up so I have to power it off manually.
Do you configure the laptop to enter hibernation while closing the lid? Can you press the power button to wake up the computer? I recommend you to check these settings in Power Options. Try to reset to the default power settings and see if the issue persists.
