10W? That’s incredibly low - under 10mA wherever in the world you live. About the same as an LED bulb, or a tenth of an average incandescent lightbulb.

For comparison: my NAS and NUC (mix of HDD and M.2 drives; both hosting services) draw 75W combined at idle, measured via Home Assistant and a smart plug, and that’s generally considered low-power self-hosting.

I’d be pleasantly amazed if you could get a laptop to use less, so I look forward to other replies.
