    I'm troubleshooting an electronic buzz in the laptop after installing windows 7 per Panasonic's directions and drivers.

    Could someone with my setup please tell me if you have the..

    "PCI Express Active-State Power Management (ASPM) has been disabled due to a known incompatibility with the hardware in this computer."

    error?

    To check, launch a command window (cmd.exe) and then type

    powercfg -energy

    then view the report html report

    Thanks.

    And the noise is not present in Windows Safe Mode

    Try doing differnt things to see if it goes away. Turn the brightness down, volume up, all kinds of stuff. ! of my 30's used to do this but has since gone away. There is something to do with the USB that's doing it. I will check your request right now.

    Yes Toyo, a USB issue, the Fingerprint Reader. After giving up my night to restore comfortable computing, I found the issue (I literally would get multi-hour long temporary tinnitus symptoms after using this computer). I restored Windows Vista OEM, installed Windows 7 per Panasonic instructions over it, only, I left out the finger print reader software. There was another error mentioned above from the energy-report.html: The UPEK TouchChip fingerprint reader could not be put into USB power suspend. I read the fingerprint readers need constant power and are an issue in power management schemes. I put the old operating system back in and uninstalled the fingerprint software (was Win7 approved) and the noise left! Swapping James Bond computing for comfort computing is kinda a drag, but necessary. If Windows 7 wasn't so stable after months of installing and uninstalling software, I'd use the fresh install, but Microsoft got the OS right this time. Tomorrow I'll pull this smart card / finger print reader see if I can't mod a switch.
