I have centos 5.4 on an HP laptop, as below the /proc/cpuinfo shows Dual core, however, there is only 1 processor listed in /proc/cpuinfo.
Is the OS only using a single core?

Check the BIOS, I have seen HP desktops that have option in BIOS to turn off multicore support. Then only single core is exposed to the OS.

How many processors are shown in your process monitor/activity monitor?

Looked in the BIOS and there was no setting.
Top is only showing 1 CPU.

What kernel are you running? 'uname -a' output?

What's the status of ACPI?
Is it enabled in the bios? Is the acpi service installed and running?

Still have not seen the uname -a output...
