Disable all the power saving features in the Bios and you will see your speed go up to normal. C2 features and C3 will lower voltage and speed and make sure Cool and quiet is disabled Michael -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
