I'm using a 2009-era laptop as a server (ssh, http, irc-bouncer). Having tested the power consumption, (with the screen off), it sits at 6.5 W in idle, according to powertop, so it's very convenient. (I'm quite surprised by this figure, as I doubt modern Core M cpus can be much better than that). It's a P8400 cpu.
- sspiff 10y agoModern CPU's and systems can do much better than that. A colleague of mine has a Dell XPS 13, and with the screen off it sips ~3.4W being mostly idle (running Unity desktop doing nothing). I was surprised by this, since the last time I took the time to optimize my laptop's power consumption was in 2010, when 17W was a respectable result. It's not just the CPU, either. M.2 SSD's are quite a bit more power efficient than SATA, and when you're going to low single digit power usage, even those things start to stack up.
