I prefer to try stuff in a VirtualBox guest before I do it on a physical machine.
In a Linux (Arch Linux to be specific) guest I put the system in suspend mode either by issuing
Or from the host system (my machine is named Arch) by
VBoxManage.exe controlvm Arch acpisleepbutton
Something happens, I guess it works. The screen goes blank except for a static (non blinking) cursor in the upper left corner.
How do I exit suspend mode? Just typing keys and moving the mouse does not seem to be enough. I looked around but could not find a way to do it from the GUI or
VBoxManage. Is there a way?
