    I installed windows 7 Ultimate version on my Portege M400. all works except the sound.

    There is a error in device manager under other devices - Unknown device - details hardware Ids--> ACPI\TOS620A. not sure if this has anything to do with the sound.

    Please help.

    Thanks
    Mani

    Hi

    I have founded a similar thread regarding this no sound problem and the unknown device TOS620A. Check this:

    But I can say that TOS620A has nothing to do with the sound. I think it has something to do with Bluetooth or HDD protection…
