Key words: AMT, vPro. You should have compatible CPU and board. Remote KVM is provided via VNC protocol, so any VNC viewer should work. You need to open web interface and proceed from there.
Basically it's a business feature and usually not available on consumer laptops.
And very annoyingly not available on the Intel NUC, even though remote-managing those would be very useful. I guess something about not wanting to canabalise their server market.
If IME could be reprogrammed then maybe there would be a way to add these features.
Well, AMT looks very tempting because of the functionality.
On the other side because of security, I'm not sure whether I should be glad to use NUC models that don't have it at all.
So assuming I take the risk, what networking link does AMT require? Do I guess correctly that it works only over Ethernet? Thinking of mobile devices that have only a cellular modem link.
Intel NUC are weird little devices; for my home file server, which at most ever has one user accessing at a time, I replaced an old PC tower with a NUC and a 5 disk USB3 SATA dock. It works better, has excellent Linux support, and uses less power.
The device is weird because it strikes me as the perfect HTPC, and yet it isn't really marketed as such.
I've bought something like 10 of them (the oldest two are Gigabyte Brix, but I'll count those with them). There are a few home servers, but the main use is as a pool of machines to use for oVirt, Open Stack, Kubernetes and RHEL work. The machines get wiped and repurposed quite a bit.
They're a lot more convenient for this than actual 19" servers, since they take up a tiny fraction of the space and power of even a single server. However they would be so much more useful if I could remote IPMI into them rather than having to find a monitor, keyboard, HDMI cable and mouse every time I want to fix them.
They would also be reasonable for home theatre since they are silent and low power, while at the same time having decent CPUs, but they use Intel graphics so I guess they probably can't drive 4K + 60Hz displays, although I've never actually tried.
I only drive a 1080p display with it, so I couldn't comment on 4k; however, it runs most everything I throw at it from my Steam library, reasonably well. The newer Intel GPUs aren't that bad, and most games don't need much to be fun.
Lenovo had at least one model in each generation's lineup with vPro support since at least the X200/T400 (so just over 10 years).
Rule of thumb (as far as I know, not exhaustive): No i3 model has vPro support, i5 models may or may not have vPro depending on the particular CPU used, and more or less all i7 models have vPro.
