Hello,

I have Compar Armada 110 and I already patched few DSDT for Compaq notebooks
as Armada 110, Evo N110, Evo N800c and similar (they are nearly the same :-).
The symptons were the same - lot of syntax compile errors, off-by-one error,
battery status not reading properly, ..... You could try to search this list for
messages from me and try to repare yourself, or you could send me you dsdt and I
will try :-)

As for debuging DSDT, you could you DSDT's debug facility, ex: Store("Some text
you want to be printed",Debug)

Bye
