Thanks, Bob.

I guess that BIOS writer forgot to delete _AL0 definition :)
Instead, you can delete these lines and override DSDT, I think.
Name(_AL0, Package(0x1) {
FAN_,
})
Thanks
To my memo:
DefinitionBlock (
"acpi_dsdt.aml", //Output filename
"DSDT", //Signature
0x1, //DSDT Revision
"COMPAQ", //OEMID
"AWRDACPI", //TABLE ID
0x1000 //OEM Revision
)
