			The "Power off MD" button on the orbiter will send a Off command to the MD, without specifying suspend or halt. As default, this will halt (power off) the MD, but it can be overridden to suspend instead. To change this, open the advanced page for your MD and fine the "PowerOff Mode" data. Setting this value to "S" will suspend it, "H" will halt it.

 This article describes how to suspend your MD to RAM (standby) or to disk (hibernation).

-PM-utils are the new package in Ubuntu 810 that are responsible for suspending and resuming your computer. It uses the HAL database to find information about what special tricks it need to pull off to get your particular hardware to successfully resume.
+In the web admin => restart there is a button "Suspend" for each MD. Pressing this button will suspend the MD.
 The setup for pm-utils was tested after completing the hibernate setup below, so you may have to include some parts of that to get this to work. In particular the NVidia part may be required.

			== Current problems ==

			The devices running on the resumed MD will not receive any messages from the DCERouter. This has to do with the TCP connections being broken after a period of suspension, or if the core has been restarted or the router reloaded.

			To "fix" this, it is possible to restart the devices on the MD at resume. Add a file to the /etc/hibernate/scriptlets.d/ folder. The content should look something like this:

			AddResumeHook 15 RestartDevices

			RestartDevices() {
			killall -s SIGKILL App_Server
			killall -s SIGKILL Xine_Player
			killall -s SIGKILL MythTV_Player
			killall -s SIGKILL LIRC_DCE
			# possible also add these
			killall -s SIGKILL External_Media_Identifier
			killall -s SIGKILL Mplayer_Player
			killall -s SIGKILL SimplePhone
			killall -s SIGKILL Disk_Drive
			killall -s SIGKILL HAL
			}

			Add a new line for other devices that you might have running on your MD.

Ubuntu 710 removed the s2ram utility used to suspend-to-ram. But suspend to disk may still work, depending on your hardware and drivers. It might also be possible to use the s2both command, which is supposed to suspend to RAM and at the same time write the image to disk, to have a backup in case of power-out.
