If it was the CMOS battery, why would it be working fine for days, stop working, then start working again after a reboot? Also, I've never heard of Linux being capable of checking the CMOS battery. What specifically is doing this check? Additionally, the CMOS battery is only needed when the system is powered down and/or doesn't have external power. It certainly isn't used to keep the system clock running while the system is running on external power. I appreciate your feedback, but what you're saying really doesn't make any sense. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
