not turning off going to sleep when lid closed
Rookie maneuver.
not turning off going to sleep when lid closed
Rookie maneuver.
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!
But it looks like it's sitting on carpet which would definitely block the vents
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.
I had a dell latitude for my first server. even when I removed the magnets, some how it still would detect that the kid was closed and turn off. I tried everything I could think of and more, without any luck. the solution? I removed the display entirely so it couldn't be closed and only used it via ssh or a VGA monitor if I really needed it.
It's probably to prevent overheating.
Why is it just sitting on the carpet though?
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...
you see ivan, server is much happier when comfortable on carpet, you can tell it wams its heart
I mean, literally just lean it against the wall, at the very least...
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
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.
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.
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'
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
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.
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.
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
Heat pumps can actually be over 100% efficient if you’re measuring it based on heat produced. Because heat pumps aren’t designed to produce heat; They’re designed to move it around via refrigerant. And if you can use 1w of energy to soak up and bring in 3w of heat, you’re now 300% efficient.
So by that metric, a server would be a “bad” heater. It would still contribute to your heating, but not as much as a heat pump would. It doesn’t mean the device is below 100% efficient, it just means the bar for “good” heaters is much higher than 100%.
Not really, electricity is pretty cheap when you live right beside the largest hydro plant in South America.
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.
Sure, it's part of windows settings under power management.
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
Yes, in most OSes it’s just a setting you can toggle. But even if you can, you may want to leave it open for cooling. Lots of laptops are barely cooled enough to support themselves, and will often rely on radiating heat out of the case as a form of passive cooling. And even when the screen is open, they still struggle to stay cool. Closing the lid often makes these cooling issues much worse.
I have a minecraft server running on an old chromebook which I installed arch on, though I made sure it stays on when the lid is closed (screen still turns off).
