here is the code:


public enum ChassisTypes
{
Other = 1,
Unknown,
Desktop,
LowProfileDesktop,
PizzaBox,
MiniTower,
Tower,
Portable,
Laptop,
Notebook,
Handheld,
DockingStation,

SubNotebook,
SpaceSaving,
LunchBox,
MainSystemChassis,

SubChassis,
BusExpansionChassis,
PeripheralChassis,

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;
}


Answer

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.
