Methinks that depleting the battery to 10 is a very severe wear on it. I would go for 50% tops. If the system is not capable of going down fast...
If you try to power down my machine at 23:50 hours, it will not go down till 00:15, or worse, 00:30. Other times, yes, it will go down fast.
Eh...,
Normally I agree, but here you are just handling the power fail case. I always get to my machines and shut them down before they reach 10%. Only time they exhaust the battery to 10% is if the office goes down at night -- and well, that's what the $25 batteries are supposed to do. Regardless of the number of discharges, I always get 3-5 years out of the batteries. I have a separate UPS that only powers the cable modem and wireless router, I will let go to the 10% for any outage that lasts that long. Generally gives about 2.5 hours of runtime.
Setting at 50% would be fine, that would just shorten the runtime to power off. Whatever you set it at is fine -- just make sure it is set :)
It is not set yet, I'm trying to read up material :-) (I hate having to become an expert to be able to use new tools) The only computer that now runs "nut" is the mini server, which runs 24*7, so it can be running with me away. The desktop machine, I should be in the house if it is running. The other day the mains power failed (the house earth fault switch triggered), and the mini server went down, its UPS could not take the load for maybe the 2 minutes it took me to notice and reset the switch. The other two UPS in the house took the load just fine. So I started to look at nuts again, hopping the thing would report battery life. It doesn't. There is an applet in xfce that reports battery life of the wireless keyboard. I think it also said something about the UPS several years ago, dunno. I had an UPS daemon thing running perhaps a decade or two ago. I changed UPS brand and it stopped working, and I did not take the effort to configure it again. -- Cheers / Saludos, Carlos E. R.
