I submit DSDT again, as a BIOS update have changed them.
Interesting for the curious is that there are changes in graphic sections.
In both cases, it seems that discrete ATI is turned off if the computer detects that OS is not Win7. In fact, there are no ATI drivers for XP in HP support, only for Win7.
F16 and F23 in file names are the past and present BIOS versions.
