I just got this on my box last night, but it never gave up after a few minutes, but continued for about 15 minutes when I gave up and powered it down. > After a restart, I often go through long periods without these messages. > But once they start, they occur quite frequently.

APM isn't even enabled on my box now, so I don't think it's APM. > My question is: has anyone out there seen similar behavior on any model > of laptop? If so, what did you do to correct it?

But, I have seen similar behavior. :( Nate
