Another method to detect hardware as laptop only is to look for the presence of a battery
based on the BatteryStatus property of the Win32_Battery class. By using the
Win32_Battery class, we can search to see if there is a battery present. If the battery status
is not equal to zero (BatteryStatus <> 0 ) then you know that it is a laptop.
