You have a couple issues there. I own a Compaq 3015US and have the same issues.
This one is because these newer compaq laptops do NOT support APM (or any other legacy items whatsoever). APM is not working in Windows, it is ACPI supported power management. So you will need to recompile your kernel.
Download the latest acpi code from http://sourceforge.net/project/showfiles.php?group_id=36832
use this to patch your included kernel source. If you do not do this you will have working acpi, but none of it will work.
enable acpi in the kernel and compile. This will give you working acpi. If you wish to hibernate as well, patch the kernel with the swsusp code and you will have hibernation.
remember to 'make mrproper' before you compile or it will not work.
I hope this helps.
