Thanks all for the reply. What is the worst thing can happen from excessive static? We have two corrupted UEFI when we reboot servers which now I suspect because of static.

That just blow my mind and made me ask you in this list. _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
