It works great, many thanks
the only settings remaining in the 'bad' state after executing it are :

Bad Wireless Power Saving for interface wlan0
Bad NMI watchdog should be turned off
Bad Power Aware CPU scheduler
Bad VM writeback timeout
Bad Enable Audio codec power management

Someone know about this Power Aware CPU scheduler? It seems I never heard about it outside PowerTop.

I think that it means the scheduler settings which try to control core and hyper-threading usage.

There are two of them. I think one controls if threads are concentrated on one core until it is overloaded, or spread out to all cores evenly. The other one is similar but controls if threads are scheduled on hyperthread siblings first, or scheduled on really separate cores.
