I thought this video was rather interesting, because at 12:27, the presenter crunches the numbers to find out how many years it would take for a new computer purchase to be more environmentally friendly (in regards to total CO2 expended) compared to using a less efficient used model.
Depending on the specific use case, it could take as little as 3 years to breakeven in terms of CO2 if both systems were at max power draw forever, and as long as 30 if the systems are mostly at idle.
I use a 2011 ThinkPad X120e as an FTP/Syncthing server. It was underpowered as a laptop from day one, but still works fine as a lightweight server. The best thing about ThinkPads is that TLP allows you to set min/max charging thresholds, so that you can keep an old battery in good shape for … well, I’ll let you know. This one’s 14 years old and still has a four-hour run time.
One thing I’d like to try is “Wake My Potato” for shutdown / automatic restart when a power outage occurs.

@BackYardIncendiary @ProdigalFrog If you have an old latitude, newer kernels also allow you to set min/max charging thresholds. My syncthing server (and NAS and a few other things) is an old 2013/2014 dell latitude e7240. It’s not the original battery, but I do keep it in decent shape via charging thresholds.
Nice to know that the latitudes work with TLP, since it opens up another set of possibilities for the future!
Does that TLP work with proxmox? I was thinking about trying pm with an old Dell latitude I have, but I’m worried about the battery exploding.
Assuming it’s compatible with the hardware at all, it should. You would have to install it on the Proxmox host itself, but Proxmox is basically just Fancy-Debian-for-Virtual-Machine-Hosting and it has Debian packages so that shouldn’t be a problem. Login to the Proxmox itself and install it there.
Ha! I didn’t even realize proxmox was Debian based. Thanks!
I’ve never used Proxmox, so I can’t say. But TLP is a utility that starts at boot. I’ve used it with virtualbox running, so if Proxmox runs atop a host operating system, I don’t imagine that it would interfere with TLP.
As an additional note, I usually set the min/max thresholds at 40/80, so the battery will charge any time it’s plugged in and below 40% and stops charging when it reaches 80%.
