I have recently purchased an Alienware 14 and it is running Win Pro 8.1.  When it goes to sleep the only way I can get it to wake up is to press the power button.  No other keys on the laptop keyboard or the mouse pad will wake it up.  I have a wireless keyboard and mouse connected using USB and they will not wake it either.  I have looked at the BIOS (ver A06) and I do not see any type of wake up option.  In Device Manager, all USB "Allow this device to wake up this computer" is grayed out.  What am I missing here?  At home, I have this laptop connected to a monitor and wireless keyboard/mouse and the lid is closed all of the time.  Any help would be greatly appreciated.
