OK so i've now added the following comands to your script witch activate the last 'bad' knob i've had :

# enable the power aware CPU scheduler
echo 1 > /sys/devices/system/cpu/sched_mc_power_savings

# enable HD audio powersave mode
echo 1 > /sys/module/snd_hda_intel/parameters/power_save

# 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 frequently for background VM activity

# Disable NMI Watchdog
echo 0 > /proc/sys/kernel/nmi_watchdog

# Enable Laptop Mode - this one is a bonus
echo "5" > /proc/sys/vm/laptop_mode
