Topic: battery replacement schedule?
This question isn't so much related to system administration standpoint as much as it is hardware management.
How often do you change the battery in your PC's?
I have a number of PC which have been migrated to server roles running 24/7. Since I have all them synchronized to a common local NTP time server (getting time through GPS...), I don't see them losing time anymore, but at some point I should probably replace the batteries.
* replace batteries yearly?
* replace batteries whenever you think of it (rarely)?
* never replace batteries?
