I have the same problem!
Since I bought it the processor was always in the 20-30% but I didn't
make case
I only noticed this weekend when I installed VS 2008 Beta and the cpu
goes too 60% with cable and without cable goes to 2-3%...
I removed VS2008 and .net 3.5 and back to the normal "20-30%"...
I have a 2x2.2GHz and running Vista Business x64
I don't think the problem is a video driver, AV or firewall. if so,
the problem should happen to with wireless. The NIC driver... is the
latest and with all the windows updates installed.
I have the computer connected to a ADSL router with several other
computers. I disconnect the ADSL cable and all the other computers
cable connected to the router to test if the cause of the cpu is for
managing some not supposed traffic that the computer received.
No difference.
The process that fires when I connect the cable is the System process.
When I connect the cable, the process creates two new threads that
generates the work. The threads are from the ntoskrnl executable.
This thing is making my computer unstable when with some work, as
System process as priority....
It's weird that nobody else as noticed this...
