Could be an overheating concern maybe. Some laptops weren't designed to run with the lid closed, if it inhibits the air flow.
As right as that might be, it's on carpet!
I don't believe they put much thought into airflow and overheating...
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.
Sadly, I've actually seen a couple model laptops that were designed with one of the fan vents right above the keyboard, and only ventilated when the screen is open. VERY piss poor design, but yeah those do exist..

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

On carpet 😬
if you just moved in, server comes first, then a mattress, then the rest of the furniture
The laptop could have setup to not sleep on close and could have been laying closed, screen on the ground. Also it would have provided completely unrestricted airflow to the fan...
...but then the sign would have affected the airflow...
This is the best compromise until mom visits and steps on it.
I have killed two laptops by stepping on them. Is this a sign?
... Mum?

you see ivan, server is much happier when comfortable on carpet, you can tell it wams its heart
Yeah. That one triggered me.
I mean, literally just lean it against the wall, at the very least...

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.
RIP
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!
There's people who gut them and build a nice wood-and-allu mini-pc (not me, too lazy, would order a case).

Disable sleep-on-lid-closed.
Take out the lid-close sensor and use it in a side project that requires a proximity sensor.
isn't it Hall sensor?
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.
technically yes. usually proximity sensor is used to mean IR or sonic sensors and I read in that sense.

It's probably to prevent overheating.
Why is it just sitting on the carpet though?
To prevent underheating, they're going for a medium laptop.
Medium-well, more like.
which one of you took a picture of my jellyfin server?
Is this that thin little block holding up the Internet?
Man when I was a kid I ran a runescape private server for anywhere within 20-100 people at a time, and for the first few weeks users reported a lot of downtime, which didn't make sense to me as whenever I tried to login it was totally fine!!
Eventually figured out closing my laptop lid put the laptop to sleep and scraped together some chore money for a VPS lol
and it'll be the most reliable server you own
Well, for one it's got a built-in UPS... Too bad for the storage connectivity tho
Lol, reminds me of my old setup.
It was all old W98 laptop that I got used. I installed xunbuntu on it back when it first came out in 2006. It sat on my desk, open like that with a bit of tape over to hold the power cord because it was loose. The battery was completely dead.
It was the server I used to host all the modded maps I made for a silly little tank game. Thing ran seemlessly only going down when the power went out or somebody juggled the power cord for 5 years.
Wow five years is a long time to juggle 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-logind
If 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'
but my keyboard is a heatsink...

OMG, Y500 ? Mine is still running after 13 years!
Lenovo made some kickass computers back then.

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
You should be able to deactivate shutdown or sleep mode on lid closure with some commands. Or would the heat be an issue?

My server is a loose motherboard with a loose PSU, thrown into the living room TV rack, which I leave open for cooling. It's a repurposed (free) Athlon, DDR2. I only use it for smb and git backups, and project sharing between my desktop and laptop. What amazes me most is my IT coworkers don't find that a perfectly acceptable scenario.
That free computer is going to cost you a lot on your electric bill.
Not in winter it won't.
Even in winter, it's terrible compared to a heat pump or (probably) directly burning gas or wood.

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

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.
