Thanks for the info.
   From the acpidump it seems that this issue is related with the broken BIOS.
   From the acpidump we know that the ACPI fan device is turned on/off by the
power resource. But unfortunately it is a bogus power resource object. There is
nothing to do in the _ON/_OFF object of power resource.
   >PowerResource (FN00, 0x00, 0x0000){
    Method (_ON, 0, Serialized)
            {
            }

            Method (_OFF, 0, Serialized)
            {
            }
        }

    At the same time it seems that the FAN device is turned on by BIOS in
course of suspend/resume. And we can do nothing about it.

    IMO this is a BIOS bug. And it had better be fixed by BIOS upgrading.
    Thanks.
