is something large enterprise IT departments would use to manage your notebook over the network without having to physically find it. It also offers some security features if you feel like buying a subscription service that supports it.
If neither of those situations apply to you, the devices are presumably just wasting your computer's time checking for network communications that will never come. (Or, if they did come, might be unauthorized, though the protocol seems to be reasonably secure.)
I hadn't gotten around to disabling any of this yet myself and appreciate the suggestion. Just disabled the "Intel(R) Active Management Technology - SOL" under Ports. Anyone have any thoughts on the usefulness of the "Intel(R) Management Engine Interface" listed under "System devices"? Hmmm... this Lenovo page
seems to be suggesting there's a lot more than just the device drivers involved.
Looks like the top two items are the drivers; the second two are a couple of services. I've disabled all four. Most of the rest are applications which when not running shouldn't affect anything other than diskspace. Not sure about the WMI provider, but that's a bit beyond my top-of-the-head knowledge so I'll leave it alone.
