only detecting 1 core on quad core laptop

English Hardware

I just installed Suse 11.1 (64 bit) on my quad core (Core 2 Quad Q9000) laptop. When I cat /proc/cpuinfo it only reports 1 core and a lower cpu frequency than I expected. I do not have acpi=off in my boot parameters (as suggested as an issue in other posts I have come across). Below is cpuinfo:

I updated the bios and now I am seeing all 4 cores, however it still states that it is running at 1600 MHz rather than the expected 2000 MHz. Any suggestions?

If you are using KDE, go to the power management option (click on the battery icon in the system tray) and set the power profile to performance.

This is not a problem, on the contrary, your OS is just using a typical feature for mobile machines.
