The easiest way to TEST Active-State Power Management is just to modify the command-line in the boot menu.
after
root=UUID=c.. ro ..
add
pcie_aspm=force.

then you can check in
/var/log/dmesg
after
Kernel command line: BOOT_IMAGE=/boot/vmlinuz-2.6.39...
if
"PCIe ASPM is forcedly enabled".

if it is working add in /etc/default/grub to GRUB_CMDLINE_LINUX_DEFAULT="other stuff pcie_aspm=force"
