Peak homelabbing

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

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

OMG, Y500 ?
Mine is still running after 13 years!Lenovo made some kickass computers back then.
I think that’s a Y510p. This was the machine that made me think Lenovo knew what they were doing and were the true successors to IBM, for laptops at least.
This machine was released right before the gaming laptop age really kicked off, so its paltry GT750(M! Sometimes two of them) was about as good as it got outside of a sketchy DTR from a company you’ve never heard of. Only a few years later did the standard go way up for gaming laptop performance, with everyone and their dog getting an Nvidia 1050/1060/1070 machine.
But I really liked the Y500/Y510. Serious design that made it look like a thick business laptop with polished black surfaces and cool red key edges vs gaudy RGB sludge with LOOK AT ME I AM EPICLY GAMERING all over it. I kind of wish they kept this design style.
Oh well. Tongfang has my back now.

On carpet
wrote last edited by [email protected]Same here. I ran a kitchen server precisely like that (minus the sign) - - but on a carpet?
(as another commenter said: even if you just moved in, you put it on a box or something)

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.
alias blankscreen='setterm --blank=force; read ans; setterm --blank=poke'Thanks, but honestly, a simple cat <file> would be more helpful than a sed line. I mean, who reads sed lines?

Take out the lid-close sensor and use it in a side project that requires a proximity sensor.

TIL: maybe my local laptop-server shouldn't have the lid closed. Probably not gonna change my ways, though. What an inconvenience that'd be

Closing lid goes brrr
-
Which is exactly why it overheats so quickly when they close the lid.
Let's face it, the place using a laptop on the floor with a paper sign probably doesn't have the budget for real sysadmins. At the same time, most real sysadmins know to disable the lid-closing behavior and get the laptop off of the carpet because they've been foiled in their past by people who refused to read the goddamn paper sign.
So OOP is just in the pre-sysadmin stage

isn't it Hall sensor?

wrote last edited by [email protected]I might/might not be one.
But it definitely is a proximity sensor. Unless yours is an Apple device, in which case, it might be an angle sensor.
The term "Hall sensor" would refer to the tech used in it, whereas the term "proximity sensor" refers to its function.
It could be using any other proximity sensing technique too and it would still be a proximity sensor. -
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
I'm currently using a y510p as a home lab. Every update resets the shutdown-on-lid-close setting. Had to set up a cron job to re-disable it on boot.

If the Dexter actor is near it, the screen goes off

On thinkpads it is, there is a magnet on the bottom.
