How to check current machine type? laptop or desktop ?

I got this from http://blog.csdn.net/antimatterworld/archive/2007/11/11/1878710.aspx ,it works well on my home machine(Win2003 on laptop), it returns “Portable”, but failed on my work machine(Vista on laptop), it returns “Other”.

here is the code:

public enum ChassisTypes
{
    Other = 1,
    Unknown,
    Desktop,
    LowProfileDesktop,
    PizzaBox,
    MiniTower,
    Tower,
    Portable,
    Laptop,
    Notebook,
    Handheld,
    DockingStation,
    AllInOne,
    SubNotebook,
    SpaceSaving,
    LunchBox,
    MainSystemChassis,
    ExpansionChassis,
    SubChassis,
    BusExpansionChassis,
    PeripheralChassis,
    StorageChassis,
    RackMountChassis,
    SealedCasePC
}

public static ChassisTypes GetCurrentChassisType()
{
    ManagementClass systemEnclosures = new ManagementClass("Win32_SystemEnclosure");
    foreach (ManagementObject obj in systemEnclosures.GetInstances())
    {
        foreach (int i in (UInt16[  ])(obj["ChassisTypes"]))
        {
             if (i > 0 && i < 25)
            {
                return (ChassisTypes)i;
            }
        }
    }
    return ChassisTypes.Unknown;
}

read registry key from HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pcmcia, the ‘Start’ value, it’s laptop if start =0, otherwise it’s desktop machine if start doesn’t exist or start != 0.
