The scores just look spurious to me:

A USB device is active 100,0% of the time:
/sys/bus/usb/devices/1-1

Suggestion: Enable USB autosuspend by pressing the U key or adding 
usbcore.autosuspend=1 to the kernel command line in the grub config

Suggestion: increase the VM dirty writeback time from 5,00 to 15 seconds with:
  echo 1500 > /proc/sys/vm/dirty_writeback_centisecs 
This wakes the disk up less frequenty for background VM activity

Suggestion: enable the noatime filesystem option by executing the following
command:
   mount -o remount,noatime /          or by pressing the T key 
noatime disables persistent access time of file accesses, which causes lots of
disk IO.

Suggestion: Disable 'hal' from polling your cdrom with:  
hal-disable-polling --device /dev/cdrom 'hal' is the component that auto-opens
a
window if you plug in a CD but disables SATA power saving from kicking in.
