Re: [Apcupsd-users] status not reset on return from hibernate

[Ian S. W. <ian...@us...>]

Thanks Ted, I'll keep an eye on it.

Actually it /is/ a server.  But we have a lot of stuff loaded in ram which we
can't easily shut down without manual intervention so hibernation seems the
best way to go.  Moving from a Windows 2003 server which hibernated fine with
a usb-connected ups so it seemed a sensible choice at the time.
