I really love ThinkPad, a really efficient and robust machine

Specs sire?

With a 12" screen. I'd prefer another 12" but 13.3" is acceptable.
I'm looking at one of these:
Lenovo ThinkPad L13 i5-1135G7 11th Generation 8GB Ram 256GB NVMe 13.3" FHD
I'm not bothered about the OS or memory or the HDD. I can upgrade/replace those for free through work.

Can this run a Hive node?

What, my laptop, the X270? It's nearly ten years old. If I were running a Node, I'd want at least 32GB of memory (64GB would be nice) and an i7 CPU or even a Xeon. There might be a slight increase in performance with an NVME HDD, but I doubt it will be noticeable. (The X270 does not support that)

There's no reason why you can't run a Node on a Laptop.

Ah, then it is not of much use to me. I'm looking to upgrade my cpu with much better hardware even a second hand would do, if only it supports running the damn node🙂

Good luck! Wish you find a good one to replace old

Ordered. I suspect it will be here on Monday.
