Why did you use arch instead of other distro that known to work on many laptops, such as Ubuntu?

I tried Ubuntu and the soundcard was not detected at all because the kernel used is too old (requires 5.5 apparently). I tried upgrading to Ubuntu 20.04 and the kernel there was too old as well... Arch was the best distro I could find that used the latest kernel by default. Audio worked there.

Both Fedora and Opensuse Tumbleweed ship a very recent Kernel though.

I don't understand why the iPhone CPU thing was such a big deal. It's a perfectly sane power management feature. Apple had to choose between two options: A. Devices lose battery life per charge over time, eventually powering off randomly because not enough power can be supplied to run the hardware. B. Devices throttle their CPU over time to keep battery life per charge relatively stable, and avoid powering off. Apple…

It was such a big deal because Apple has a monopoly on „acceptable“ replacement batteries (the system shows a warning when you insert a 3rd party battery), and they charge 3x their actual worth.

That's absolutely a separate problem worth being mad about, but that doesn't change the cpu throttling thing being afaic a perfectly sane power management feature.

I'm surprised to be defending Apple on this, normally most things they do seem pretty anti consumer and leave a bad taste in my mouth. But in this specific case I really don't think they deserve the scorn.

Well, I will point you to fluffything’s response > Arch was the best distro I could find that used the latest kernel by default. Audio worked there. That mirrors the experiences I’ve had. Most distros ship with broken old software and custom patches that make troubleshooting a nightmare. They also don’t have the resources to support the wide variety of hardware out there. Microsoft spends billions on Windows and vend…

> In Linux land, the mainstream distros ship with fragile duct-taped components that work if you’re lucky but are a complete pain to troubleshoot and are a bigger pain as time goes on and you have major upgrades. Laughing in Fedora. Out of curiosity how much "mainstream distros" did you use?

Exactly my thoughts, Fedora should be given a try. I've had it on a number of laptops and desktops, and for the last few years for sure everything has just worked (tm).

Laptops isn't designed for serious workloads. It's a small portable devices to hash some errands at starbucks. You can't change physics laws unfortunately to make all the heat disappear somewhere. Keep in mind Intel marketing as well which advertises CPU with way less heat than they expose in real life. The way you have this machines is because apple is commercial company and they should follow market demands. "10 co…

In theory , laptop manufacturers that use aluminum in their chassis could just put the CPU die right up against the chassis, Remove the bottom feet, and then tell you to only ever use it sitting on top of a table designed to function as a top-down heat pipe (i.e. the kind they use to make “scraped” frozen yoghurt.) The table would become the CPU’s direct-contact heatsink. Not practical at all, of course, but this is…

It would be practical to at least have some form of heat transfer to the case for passive cooling advantage, but this can have the downside of the end user getting burned/uncomfortable and saying, Why does my computer get so hot?

The recent metal-cased RTL-SDR's from rtl-sdr-blog have this "problem". The metal case actually helps the chip run cooler, but it gets hotter to the touch then the early insulating plastic models.

PSA: If you have a thinkpad, the lenovo settings app lets you control this too. In lenovo vantage, go to Device > My Device Settings > Battery settings > Battery Charge Threshold.

This feature is what I need for all battery gadgets like smartphones, MacBooks, and earbuds, etc..

> Isn't this bad design? It’s a trade-off - they COULD build a laptop which can run everything at 100% 24/7 indefinitely, but it’d be heavier and more expensive, with zero benefits to their target audience of "people who only run at 100% for a few hours per day"

No, He is talking about the laptop not getting enough power while plugged in. If there was any added weight it would be with the charger, not the laptop so... Incredibly unlikely. It's way more likely that Apple just didn't design the connector to be able to deliver that amount of power. So they'd have to add a second one or switch connectors/design a new one. Both would be suboptimal as well.

> No, He is talking about the laptop not getting enough power while plugged in.

That’s what I’m talking about too

> If there was any added weight it would be with the charger, not the laptop so…

Whether it’s charger or laptop, that’s still more weight that the end-user needs to carry around in their backpack, which 99.9% of them won’t need
