If a system is connected to a UPS (Uninterruptible Power Supply), it is possible to determine how much power it consumes. For this purpose, I wrote a small script:

 Host:~# ./ups.sh

 UPS model: Back-UPS RS 1200 LCD
 APC model: Back-UPS RS 1200 LC
 Capacity: 720 Watt
 Load: 18 Percent
 Usage: 129 Watt
 Time left: 33 Minutes
 Status: ONLINE

 Host:~# ./ups.sh

 UPS model: Back-UPS RS 1200 LCD
 APC model: Back-UPS RS 1200 LC
 Capacity: 720 Watt
 Load: 19 Percent
 Usage: 136 Watt
 Time left: 22 Minutes
 Status: ONBATT

This script assumes that:

1. You are running a unix

2. You run apcupsd

The script can be downloaded here:

When using a Mac Mini as a server or router, it is very nice if the machine automatically boots if a power failure has occurred.

User chirhoxi on the ubuntu forum found out how this can be achieved:

Basically you need one of these commands:

Original Mac Mini:

setpci -s 00:03.0 0xa4.b=0

Newer Mac Mini:

setpci -s 00:03.0 0x7b.b=19

These commands might not work with the latest Mac Minis but the thread discusses how to determine for yourself what the appropriate command is.
