I didn't find the manual so I can't see if this is documented.
Since power settings are widely documented about Windows 8 such as http://techmell.net/windows-tips/change-windows-8-power-options-launch-setting-details/ and hundreds more I'll not write how to change this to not sleep on lid closure.
As to the wake on USB as there is no manual I can't look to see if there is a USB Wake in the bios. Find the manual so folk can check that out.
I use a Gateway NE56R49u Windows 8 laptop, which I sometimes use to connect to a Dell computer monitor via VGA and an external keyboard and mouse using USB. I want to be able to use the monitor with the ext. mouse and keyboard while the lid of the laptop is closed, however, everytime I close the lid the system goes to sleep and won't turn back on even if I move the mouse or press a key on the keyboard. I've tried going to Device Manager and enabling the mouse and keyboard to wake my Windows 8 laptop but that seems to have no effect on what happens when I try to wake my laptop when the lid is closed. I am able to do this on a Windows 7 laptop (HP Pavilion g6), but how can I configure my windows 8 laptop so I can do the same on my Windows 8 laptop?
