Finding out which machines are Laptops in a domain

  • Articolo

Say you want to provision some settings only on all laptops in your corporate domain. The problemthough is, how do you identify which computers ones are laptops?

WMI Class win32_systemEnclosure has a property - ChassisTypes. ChassisTypes is 9 in a laptop.

Addtion based on reader feedback: ChassisTypes might not be 9 always, on some machines you'll see 8 (portable), 9 (notebook) as well. It is also a good idea to look for batteries as well using win32_battery class.

    It seams that testing for 9 is not sufficient. For example my laptop has 8 - Portable.

    Hi As Max mentions here above, using this is not the best idea. The workaround i use is to check for batteries. brgds

    Thanks for your comments Max and Bruno! checking forBattery does seem like a good idea. I'll add that in a followup post to this.

    As mentioned not the best option, additionally checking for just one isn't always the greatest.  I've had the best luck using a combination of Win32_Battery, Win32_PortableBattery, Win32_PCMCIAController and Win32_PhysicalMemory.
