I bought my Inspiron 5150 in November 2003 and selected a 3.06Ghz processor with Hyperthreading enabled, I did check the correct box when ordering online!

I checked that hyperthreading was on, by looking up device manager in "system information" through the control panel - As many others have pointed out on this forum I would know hyperthreading is enabled as the device manager would show two P4 3.06Ghz processors.  This was the case, I could see two processor icons - But....

Checking back to this menu I can only see one processor icon now and cant find a way to enable hyperthreading anywhere.

I want to enable hyperthreading and would like to know how I can do this now.

Any ideas?
