Hello for the ACPI\IFX0102\4&28738126&0 driver, since it's a Compaq nx9420, you need to download from HP support the HP Embedded Security For Protect Tools and Infineon TPM software driver that has the reference (sp32486).

Confirmed HPQ0006 is indeed the HP Quick Launch Button. It works on my HP Compaq 8710p Download at this address: http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=en&prodTypeId=321957&prodSeriesId=3369264&prodNameId=3355687&swEnvOID=1093&swLang=17&mode=2&taskId=135&swItem=ob-56605-1
