Peak homelabbing

Even in winter, it's terrible compared to a heat pump or (probably) directly burning gas or wood.
That's the joke.

Serious question that I've wondered about but never worked on.
Can you rig a laptop to keep running with the lid closed? Either by software or hardware? I guess you could cut the switch, but an OS-based solution would be neater.

Yes, easily. Most OSes let you do that.

Disable suspend when the laptop lid is closed:
sudo sed -i 's/#HandleLidSwitch=suspend/HandleLidSwitch=ignore/g' /etc/systemd/logind.conf sudo sed -i 's/#HandleLidSwitchExternalPower=suspend/HandleLidSwitchExternalPower=ignore/g' /etc/systemd/logind.conf sudo systemctl restart systemd-logindIf you are in a TTY, you can blank the screen before closing the lid to prevent burn-in. After running this, come back later and press a key to turn the screen on again.

In some cases, is a bios setting also.

Yes usually it's the OS that handles it and it can be set to ignore the lid detection.
I did it for a while. Also removed the battery so it doesn't start swelling

Sure, it's part of windows settings under power management.

And the lid is not open because of preventing it sleeping, but rather to cool it down

Same with Linux!

See I would have more problems with cats chilling on the keyboard than folks closing the lid or unplugging it

This laptop is secretly downloading scientific papers behind a paywall to release them on the public internet. Sadly, the owner will be prosecuted unfairly and threatened with unreasonable punishment.
Remember Aaron.

Could be an overheating concern maybe. Some laptops weren't designed to run with the lid closed, if it inhibits the air flow.
I can't tell for sure, but it looks like a Lenovo y510p. Or at least it looks very similar to the one I owned back in the day.
There was a vent in the hinge, and these things would absolutely cook themselves with the lid closed

That free computer is going to cost you a lot on your electric bill.
Not really, electricity is pretty cheap when you live right beside the largest hydro plant in South America.
-
if you just moved in, server comes first, then a mattress, then the rest of the furniture
You could put the laptop on a box

OMG, Y500 ?
Mine is still running after 13 years!Lenovo made some kickass computers back then.
I instantly recognized it too! Mine got stolen. I loved mine.

Not how heat works.
If you're trying to heat your home, every electronic device becomes 100% efficient. All its "waste" heat becomes wanted heat. That it might only be 40W of heat is not the point.

Yes! Very important!
I remember it being a bit trendy to turn old laptops into desktops by just unplugging the display and plugging peripherals into them, but people were finding that the keyboard actually was designed as another heat escape, so running them with the lids closed wasn't so great!

Or a local library and $0.10
Right on. This fellow libraries.

wrote last edited by [email protected]Every electronic device is 100% efficient after the electricity has already been generated and delivered, sure, but a bunch of efficiency losses occurred before that. If you're comparing methane burned on-site in a furnace to methane burned at a power plant, transmitted to the site as electricity, and then used for electric resistance heating, burning on-site is gonna be better even if the furnace loses more heat up the chimney than the power plant does.
Also, a heat pump is "300%-500% efficient" in the sense that it moves 3x-5x as much heat as it uses. See also: https://en.wikipedia.org/wiki/Coefficient_of_performance
