Nothing like packing up your laptop at the end of the day, clicking "sleep" and wondering if it actually will cooperate or if you have open it back up and close random tabs and programs till it does,then waiting for the fan to audibly stop before putting it into a bag!

it's gotten to the point now where laptop manufacturers tell you not to put sleeping/hibernating laptop into a bag at all due to amount of heat they still generate even while sleeping [0]. Only those that are fully shut down should be placed in a bag (according to them). [0] https://www.dell.com/community/XPS/FAQ-Modern-Standby/td-p/7...

I miss hibernation. Real, write the contents of RAM to disk and shut-off completely type of hibernation.

Amphetamine[0] works pretty well for me. They also have an extension (a kext, I think) that gives it more reliability. I don't know how reliable it is without that extension though. [0]: https://apps.apple.com/us/app/amphetamine/id937984704?mt=12

I've been using the more bare-bones KeepingYouAwake[0] just because I came across Caffeine first and this was suggested as the continuation of that simple utility. The icon makes it obvious whether it is enabled or disabled Edit: I see now that Amphetamine has the option of a similar-looking icon to make it more obvious whether it is enabled or not [0] https://github.com/newmarcel/KeepingYouAwake (My first HN comment…

I used Caffeine for years and never really thought about it much, it's always been useful. But I installed Amphetamine lately on a new MBP and I've used the schedule and countdown modes multiple times now. It's a great tool and the added functionality is useful.

So I like this and I'm trying it out, it seemingly works OK. However, the GREEN background is very annoying. I don't need the whole webpage to be green for me to know it's on and working. I can't minimize the browser (firefox) because then it apparently doesn't work. So I'm left with a very big green screen sitting in the corner of my eye. Wondering too the effect of that in terms of screen color burnout (if that's e…

Using #000 would save the maximum power for any device with an OLED panels (like my laptop and my smart phone). Given that the idea is to keep a device on and some screens not being smart enough to understand this is an okay time to power down, #000 would be the only ethical color scheme to use. If you added a jitter to the placement of text over time, you could prevent possible burn in as well.

So i get annoyed that my computer doesn't go to sleep sometimes because some website is playing a video. Is there a simple way to tell Linux/Gnome/Chrome to ignore videos and go to sleep anyway? I don't watch long videos on this computer so I hate to come back into my office and find my screen never locked because some website played a video i wasn't even watching.

Firefox (at least in Windows) does allow sleep when there's a no-audio video.

This is true now. But for awhile did not and any video would keep the PC awake.

Ended up being a security risk at our company because someone in marketing didn’t know this and made a full screen video. Well, cleaning staff came in and almost all our PCs were on because lots of people use the company website.

Fixed that nonsense right away.

I have higher standards for my computer than sleeping with just a webpage.

I fully expect mine to f' everything.

I wouldn't let my computer sleep with this because it could get a virus and then before I know it I'm getting asked for money and if I don't pay up my nudes are all over my social media

This is awesome my work computer has a stupid 5 minute setting until it sleeps that is locked.

If it's really locked down, you can find USB devices for a few bucks that emulate a mouse and move by a few pixels every minute. Foolproof for those companies with nonsensical settings or nonsensical spying.

I use AutoIt to move the cursor and it's free.

Sorry, i'm a kde user but not sure how this would be done...? Would you kindly provide details, or a link to a how to?

There's a checkbox "Manually block sleep and screen locking" and you just check that.

Where in the system tray is it? Do we need to click the battery icon or something? Maybe because I'm on a pretty old version (5.18.6), I don't see that checkbox anywhere I looked.

Additionally, something to tell me whether my PC will go to sleep or not if left alone. OP's problem happens to me every so often that I need to make sure the PC is indeed going to sleep before heading out.

I think on Windows you can run powercfg /requests I'm not sure about linux or Mac though

Another super useful powercfg flag is /lastwake to tell you why the computer woke up from sleep.

Has helped me identify flaky input peripherals or timers many times. Worst was an HP laptop with a wonky touch bar for media controls, that would frequently ghost press and wake the computer, even when in hibernate and with the lid closed.

Cut the browser off from anything but the xorg and pulseaudio sockets (no dbus!). Then it can't place any inhibitors.

Mine still does that.
