After I shutdown my XPS 8500, the monitor goes off, the power and other panel lights goes off but the processor and fans keep running, and would continue for hours if I don't pull the power cord. What is causing this? Any suggestion for a fix would be appreciated.
When did the issue start? Are there any bluescreens / system crashes? Does the hibernate / restart option work fine? Is the issue seen only with shutdown option? Are there any external components connected to the system all the time?
