I have a Dell Inspiron 1000 and have recently replaced the factory Celeron 2.2GHz processor with a Pentium 4 2.2GHz processer...SL6J5. It works fine except that it runs at 1.2GHz. I have downloaded Rightmark and Notebook Hardware Control and am unable to increase the speed. My research has shown me that the 1.2GHz is the battery mode speed of the SL6J5 processor. The laptop seems to run a bit faster than before even at the slower speed. I have already updated the ram to 768Mb. Any help would be appreciated.
