Fedora command for motherboard clock condition (from: f24 boot fails; need help).

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Good afternoon,

In the "f24 boot fails; need help" topic, a log file extract had these 2 lines:

1533 [ 4.022605] coyote systemd-fsck[428]: /dev/sda6: Superblock last mount time is in the future. 1534 [ 4.022745] coyote systemd-fsck[428]: (by less than a day, probably due to the hardware clock being incorrectly set)

One person noted
"The time problem suggests that the little pancake battery on the MB that maintains the clock might be out of juice. I think these are 2032 style for PCs. It would be a good idea to replace it."

I responded
"I didn't know workstations nowadays had batteries. When the system is back on its feet, I'll try to check that. It was bought in 2013."

I knew that the older motherboards had batteries. But I thought the newer ones used something like flash (or other persistent) memory. It did not occur to me that booting might want the date/time before the boot process reached the point of being able to access the internet.

Two people corrected me.  Someone else in the discussion said it well:
I sit corrected!

Fedora seems to have a huge number of commands. Does Fedora have a command to report the condition of a full-sized tower motherboard battery? If yes, what is that command?

thanks,
Bill.
