I wanted to ask and see if there's a way to plug in the charging cord when the laptop is off and it won't power the device on? It's for a MacBook Pro 14. I remember the old laptops used to allow you to plug in and charge while the laptop was turned off. It's a bit annoying so far when I want to charge with the laptop being turned off and then suddenly it forces it to come on. Please let me know if there's a setting that I can adjust, thanks!

How to turn off 'power on' when plugging in charging cord?

No. There is no way to do that. May I suggest never shutting the machine down? That’s how it’s designed to be used.
It doesn't turn on with the lid closed, I'm sure? At least my Air (M1) definitely doesn't.
That's a myth, brought about by the fact that Macs of old didn't seem to need rebooting as often as PCs, back in the days when booting either a Mac or a PC from cold was a bit of a drama due to the HDD speeds. These days where either a Mac or PC will boot to desktop in 30 seconds or less, I can't think of one practical reason why anyone should leave a machine turned on that they're not using. One way or another it's using power unnecessarily that they'll pay for at some point, in exchange for waiting 30 seconds for the computer to boot.
You can't think of a practical reason? Being able to open my computer and instantly have every document open and arranged exactly as it was -- that right there is worth the little bit of power consumed in sleep. Sounds pretty practical to me, because it saves me easily 5 minutes of arranging everything as it was. Sure, a Mac can boot up in 30 seconds these days, but it's more than that before every app you use is opened and synced and ready to go. And with battery life what it is under M-series processors, there's not a lot to "pay for" in terms of power.
As far as how it's "designed to be used" I'd argue that sleep is well supported, based on features like Power Nap that let cloud syncing happen in the background.

Fair enough if that's your workflow. I don't have dozens of things open at once. That workflow is alien to me and always has been. When I've finished with something, I close it down. That goes for documents, browser tabs, apps, and ultimately the computer. I had it out with someone on here last year who argued a computer than couldn't managed 200 browser tabs open at once without becoming sluggish was useless to anyone these days because that's what typical users do. The notion of that workflow to me is just totally insane, and I just can't believe it's typical.
And as for sleep being 'well supported'...that again is going to entirely depend on your use case. Fine if all you do is use your laptop or computer as a standalone. But it doesn't work so well when the computer is rigged-up to a truckload of external hardware and every time you wake it you have to either reboot it anyway in order for it re-find something that's 'dropped off' or unplug / re-plug the missing devices. That's been a problem with Macs for years but got exponentially worse with with M-series.
So I guess that's where I'm coming from when I say I really don't get any practical reason why people don't just shut it down when they're finished. Everyone's opinions are blinkered by the limits of their own experiences, and my experiences are it's always better to start each day with a fresh reboot and shut everything down at night.
But as always, you do you.
Sure. Between fast boot times and long battery life, Macs are flexible enough to support whatever work habits one may prefer. Turns out, shockingly, that people have different workflows. But I guarantee you for every "reboot every day" user, there are many, many others who simply close the MacBook when they're not working and open it again when they are. There are plenty of practical reasons to do so and the penalty to battery life is minimal. If it's a "myth" that Macs are designed to work this way, why would plugging in the power cord boot the machine automatically?
Only with the lid open, which is actually annoying for some, and is the reason this whole thread was started.
I think it's a legitimate request and it is very well possible. At least on T2 Intel Macs you can disable Auto Boot (so the MacBook won't automatically boot up when opening the lid).
It also disables Auto Boot when plugging in the charging cord.
I think I saw posts it still works on Apple Silicon.
Code:
sudo nvram AutoBoot=%00
