It’s not just the size constraint. The power usage is significant…
If you have the lid closed, you’re looking at 3 to 15 watts to have a laptop running in the background doing some basic server shit.
Maybe a little more under high load, but those are going to be intermittent and not constant.
I’m just saying it’s not that much more electricity usage, and the recycling more than offsets the CO2.

Not all laptops make effective use of power with the lid closed, sadly. Not saying this as a correction, but for others to know that they need to make sure these settings are available in the bios of the system they are buying.
Laptop performance when closed is quite variable, but depending on where you live, each 10W of idle consumption 24/7/365 could cost you somewhere around $20/yr (assumes @$0.20/kWh, YMMV). This isn’t overwhelming on it’s own, but it is “cost difference between a junked laptop and a Raspberry Pi” kinda money.
And you are often paying 140-200 for a pi nowadays to make it have the same usability as a laptop (pi, power supply, sata hat, data drive because SD cards simply fail after a while under server IO) while you can get cheap used laptops for 0-100.
So unless you are running it for more than half a decade (which rarely happens with selfhosters for a main server), you are probably spending more in total on the pi.
Laptops are not generally designed to run like that with a closed lid. Heat dissipation is designed around the idea the laptop is open and some of it is through the keyboard surface. The lid closed would change that.
Systems can of course be setup to power off the display but for server/service uses open laptops may not be efficient space wise.
Having said that if the scenario is low power use the heat dissipation may not be a major issue. But if there is an unremovable battery i’d still be concerned about heat dissipation with the lid closed and even just the battery itself regardless of heat dissipiation.
Just remove the lid entirely.
Not so sure about the last part. It takes ehhh about 3kg of c02 to produce 1 Watt for a year. Carbon footprint to build a laptop is about 200kg or so, but you’re not offsetting one of those you’re offsetting the raspberry PI you WOULD have bought which is just a small fraction of that. After a year or 2 you’ve almost certainly burned through your c02 savings if it’s on all the time.
A raspberry pi is not as efficient as people are claiming. They need up to 25W PSU for a reason. Laptops can idle lower than that certainly. Something like a MacBook Air M1 would idle in single digit territory, as would any netbook basically ever made. Only really high performance or older laptops have idle power draw issues since battery life is a major selling point of a laptop. Said laptop is probably also faster than a raspberry pi. The people building Pi clusters are really not doing themselves any favors with power efficiency.
Nah no way does the average ewaste tier laptop use less power than a raspberry pi for any given task. The power consumption floor for a laptop may be lower than the rpi ceiling but that’s not a fair comparison
Benchmark it and tell me. The truth is that most RPis are made using older process nodes to reduce costs. Laptops are often made using the best avaliable process node and core design. A modern raspberry pi 5 uses a 16nm processor with Cortex-A76 design from 2018. A laptop in 2015 would be using 14nm Broadwell processors from Intel. This was a time when 15W U series processors were gaining popularity, so sustained load power consumption is quite low. A 2015 laptop is 10 years old, and wouldn’t run Windows 11, so will be ewaste this year. Same with a lot of 8 year old machines actually.
the 20 year old pc of my grandparents had a graphics card failure, i fixed it but tgey decided i should keep the pc and help them pick a new one (valid after 20 years ngl) now this PC runs debian and hosts my game servers and all
Power consumption is a massive reason to really not do that. Its cheap for a reason, its takes a shitload of power to be shit and you will pay more in energy than you save in hardware unless its only powered on for short periods of time - a server typically isn’t.
This is actually something that applies to cheap products too. Was in Asda a little while ago and saw 2 LED bulbs with the same lumen rating. Cheaper one used 3w more and you only saved £1. Running it for 8 hours a day for a year would cost double that saving in electricity. For a server you are looking at almost £2 per watt each year. Does that ewaste look so good to you now?
Some things are absolutely worth getting second hand, but you really should be careful considering the power cost as well.
Quick edit: If you don’t need it running 24/7, consider something like AWS too. I love selfhosting but if its not running much it might be cheaper to not bother buying hardware.
Get them from where? I always read about these basically-free computers but have yet to see one
Facebook marketplace, kjiji, etc
I wouldn’t touch Facebook with a 10’ ethernet cable. Haven’t heard of kjiji, I’ll have to check it out.

It’s essentially Craigslist, but in Canada.
Craigslist doesn’t really have a user base here.
Everyone here thinks their shit tier 2018 laptop is made of gold or something.
Where are these cheap e waste laptops with gpio and actually low power?
Digging through e-waste bins is one of my hobbies.
What kind of place do you go to to find these things? Sometimes I get really lucky (see my post history about my wonderful new printer), but if I could increase my odds that would be cool.
