Running sysinternals process explorer on my x61s I see that the CPU is
spending about 1/3 of its time in Hardware Interrupts.
According to the process explorer docs: On Windows NT-based systems
Process Explorer shows two artificial processes: Interrupts and DPCs.
These processes reflect the amount of time the system spends servicing
hardware interrupts and Deferred Procedure Calls (DPCs), respectively.
High CPU consumption by these activities can indicate a hardware problem
or device driver bug. To see the total number of interrupts and DPCs
executed since the system booted add the Context Switch column. Another
sometimes useful metric is the number of interrupts and DPCs generated
per refresh interval, which you see when you add the CSwitches Delta column
Any idea how to figure out if there is a hardware problem and how to
deal with it?
