To wake up the computer directly via mouse or keyboard, you should not close your hard disk when the

computer goes to "stand by" mode, go to power options and set the hard disk never turn off will be ok,

Some buyer face this problem, when they set the mini computer to “stand by” mode, they cannot wake

the computer up directly by mouse or keyboard, if press the on/off switch, the mini computer restart directly.

Here is the solution for above problem:

If you are using Win 7 OS: First, click on the battery icon and go to “Power Options”, you can also find

“Power Options” from “Control Panel”,

Secondly, click the > Change advanced power settings link in the bottom left.

Hard disk: Set it never turn off the hard disk in sleep mode.

If you are running XP: Open the Control Panel and switch to Classic View (if not already selected),

Select Power Options and adjust the settings in the power scheme, select never turn off hard disks,

choose ok to save  your changes.
