There's that, there's the portability, it uses less power, and for the average consumer who doesn't have a video game or computer hacking hobby, it's more than capable of performing the tasks most people are clamoring for at present, apparently a great many people have so little need to carry all that weighty hardware that they do their "computing" on cellular phones and tablets. I like desktops, and I like the idea of built-in battery power, but laptops are definitely all the rage. When I was living on my (former) farm, I couldn't get DSL or cable but a plain old 550VA UPS would keep my laptop, satellite and router running for a long time.

Of course, I am a big nerd and I would like to have a small datacenter in my home - filled to the brim with different kinds of hardware and software.

MGE-SHUT(8) NUT Manual MGE-SHUT(8) NAME
mge-shut - Driver for SHUT Protocol UPS equipment SYNOPSIS
mge-shut -h mge-shut -a UPS_NAME [OPTIONS] Note This man page only documents the hardware-specific features of the mge-shut driver. For information about the core driver, see nutupsdrv(8). SUPPORTED HARDWARE
mge-shut supports all recent Eaton, MGE and Dell UPS models which use the SHUT (Serial HID UPS Transfer) protocol. Older MGE models, such as Pulsar ESV+, Pulsar EX and Pulsar ES+, use the U-Talk protocol and should use the mge-utalk driver. EXTRA ARGUMENTS
This driver also supports the following optional settings: lowbatt=num Set the low battery warning threshold at which shutdown is initiated by upsmon(8). The factory default value is 30 (in percent), and can be settable depending on the exact model. offdelay=num Set the timer before the UPS is turned off after the kill power command is sent (via the -k switch). The default value is 20 (in seconds). Usually this must be lower than ondelay, but the driver will not warn you upon startup if it isn't. ondelay=num Set the timer for the UPS to switch on in case the power returns after the kill power command had been sent but before the actual switch off. This ensures the machines connected to the UPS are, in all cases, rebooted after a power failure. The default value is 30 (in seconds). Usually this must be greater than offdelay, but the driver will not warn you upon startup if it isn't. Some UPS'es will restart no matter what, even if the power is (still) out at the moment this timer elapses. In that case, you could try if setting ondelay = -1 in ups.conf helps. notification=num Set notification type to 1 (no), 2 (light) or 3 (yes). The default value is 3 (yes) because of some early Ellipse models which need it. KNOWN ISSUES
Repetitive timeout and staleness Some models tends to be unresponsive with the default polling frequency. The result is that you have some "data stale" errors in your system log. In this case, simply modify the general parameter "pollinterval" to a higher value (like 10 for 10 seconds). This should solve the issue. Using notification=3 might also help. AUTHOR
