Re: Fedora command for motherboard clock condition (from: f24 boot fails; need help).
After groping through papers in a moving box, I found the user's guide for the
motherboard. Amazing: something I kept actually proved useful! It's a ASUS
Sabertooth Z77, bought in early 2013. Well, no index, no mention of battery in the table
of contents. I skimmed through once, no hint of battery. I went back to the diagram of
the motherboard, grabbed the magnifying glass, and behold - in very teeny print, a circle
labelled "Lithium cell CMOS power". Rick Stevens said in another topic posting
"Memory is the second thing to go, but I can't remember the first!". Maybe
vision is the first thing to go? Y'all are correct: the motherboard does have a
battery.
The ASUS website showed how to change the battery, but that's all. Oh yes: it's a
CR2032 3 volt Lithium ion battery as some of you said.
I'm not really concerned about the $ cost of a new battery. I am concerned about BIOS
settings disappearing the instant the battery comes out, and therefore what else I might
have to do before and after the battery change. This seems like another high risk task.
I think the user's guide mentioned a way to copy BIOS to a flash stick, and read BIOS
from a flash stick. I'll have to study this properly before I actually do anything.
I did not see any indication of battery state in the BIOS display. I'll have to
install the chrony package and give it a try.
Is there a Fedora command to display the appropriate BIOS settings that I may have to
restore after replacing the battery?
thanks,
Bill.
