I have a old HP dv9500t laptop and recently upgraded it to Windows 7 from Vista. The operating system got installed and after that I installed all the drivers for the motherboard and chipsets. But when I check in Device Manager then it shows me an Unknown Device and when I checked its Hardware Id then it was shown something like ACPI\HPQ0006. Can anyone tell me where can I get drivers for this devices? Thanks.
