[ale] Linux swap space vs hibernate, power shutdown settings

[David Ritchie]

A couple of points regarding APC UPSes:

1) The batteries are replaceable, through the trap door on the bottom
for the smaller ones.APC sells batteries that directly plug in, but
probably at a bit more money. There are other local sources for these
2) The SLA batteries really only have a 2-3 year life span. You can
buy replacements at Batteries Plus - prices there are better if you
have
a commercial account (even if you pay cash for everything). There are
probably other places to get batteries, but Batteries Plus are very
available, at least in Atlanta. How old are the batteries in the unit?
3). You might consider a power strip up and then connecting a couple
of  100w lamps up as a test to see how long these will carry a load.
4) You can get Kill-a-Watt meters cheap off of eBay, which are
usefully for evaluating loads and voltages.They are also nice to have
around
general knowledge of how much power a particular device uses. A good
working number for cost in Atlanta about $1.50/watt-year to any device
that is used 24x365.
5) You can get really cheap or free UPSes if you ask around - people
don't understand about battery replacement and throw them out instead
of replacing the batteries. Electronics recycling places have these in
abundance... if you ask nicely, you might get some given to you
to repair.
6) and if you try to repair them, be careful - there are lethal voltages inside.
