I just did that on my own laptop, trying to figure out why it was running like crap. Turns out I set it to quiet mode instead of cool, so it underclocked instead of running the fan

I bought a new one recently. Apparently they’re doing a subscription thing now, so look closely at which model you’re buying. But other than that, it works just the same as my old one.

Does it work if you unplug and replug? If you hit a button other than power does it wake up, or does it say “no signal” or something? Does the laptop see it? Anything in any log? Can you force a redetection from the laptop?

You’ll need to check the logs for your display manager, probably kdm if you’re using KDE.

On Lenovo it’s usually the delete key, I think. You should check the manual. It should also be an entry in the boot options list.

You might also try a reset, but it would also be helpful if you shared the “few rolling lines of text”.

How little ram and swap do you have that this is a problem?

You might just use ulimit: https://unix.stackexchange.com/a/746762/90708

I feel like there’s a better way to do this, unless you’re intentionally trying to run out of RAM.

In whatever centos uses for a prompt, it says “press tab for echo”, and it works. You’ll need to provide more info about your environment if you don’t have that option.

Yeah. For a small shop, it won’t help. Just show up and be willing to work and learn. Save that money.

If Minix counts, I got it running on a 286 some years ago. I don’t remember how much RAM it had, but it was very little.

Yes, I’m sure there are multiple professional software solutions that are expensive but can do it. Reconfiguring the equipment is much cheaper.

Even basic stuff like teleconferencing software can do it, like do y that when Zoom is playing audio it doesn’t pick it back up through a desk mic, unless the feedback is really bad.

It sounds like your issue is that each microphone is picking up the other person’s voice. If your software is insufficient to handle this, I’d move or change the microphones.

Me when coming back to a system without NetworkManager

What do you mean “go to the respective interface and make any change”? In the firewall or client? What changes when you do this, IP address or routing table or gateway or what?

I got one so I picked it apart. The link runs a script on the local system that downloads a kubernetes runtime. From there I assume it runs a Bitcoin miner or something, I didn’t go any further.

You don’t even need to do that. You could just blacklist or delete the module.

The game wouldnt work, but you could do it.

I’ve only seen it for two so far, and after I blocked them it was fine.

Part of the problem was Sonarr trying to grab episodes that hadn’t aired yet. I think a fix for that is forthcoming. That should cut down on them. I don’t know if there is a fix to let you block extensions.

Yeah it doesn’t look at file extensions. Block the release group name. Those releases are malware.

It probably gives some useful info. What does it say? Also, what changed between now and the last time it worked?

Right, but also UPSes are usually rated in VA, not W.

The thing you’re missing is runtime. If you match your usage to the UPS exactly, your runtime will be zero. If you consume 300W, your UPS needs to provide 300W for however long it is until the power is back. All major UPS companies (APC, Eaton, Cyberpower) have calculators on their site.

But a UPS for extended runtime will be very expensive, and lead-acid batteries must be replaced every five years or less, else they will not be able to sustain a load, so budget for that maintenance too.

A UPS is really just to bridge the gap between mains power going out and a generator coming online. A large-capacity UPS will be prohibitively expensive.

Also, note that cited power figures on the NUCs are probably peak draw. They will probably draw less on regular usage; you’d have to measure it to know for sure in your specific use case.
