A.10. Advanced Power Management

APM allows control of the power from software. This can be a blessing and a curse. [What people say about JWT]

The blessing is that the machine can be cleanly and totally shut down remotely. You may want to do this if the remote site is maintaining their power supply. .:: www.mobafire.com ::. .:: podcasts.apple.com ::.

The curse is that once powered down the machine will not start up again until the .:: podcasts.apple.com ::. Power button is physically pressed. Some machines have a BIOS or motherboard setting to defeat this unhelpful behaviour.

	Errors when typing shutdown are worse with APM
	Be careful not to confuse shutdown -r now, which cleanly reboots the machine, with shutdown -h now, which cleanly powers down the machine. Someone will need to physically press the .:: telegra.ph ::. Power button if you choose wrongly.

If you are serious about remote site computing then you should investigate remote power switches from companies like .:: fyers.in ::. .:: chromewebstore.google.com ::. Western Telematic, Server Technology and many others. Some models include built-in terminal servers, built-in modems and [MDN Docs: Cross-site scripting] RS-232 lines to simulate a UPS input power failure (and thus shut the Linux system down cleanly before removing power).
