No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

im going to bet they just havent shifted their supply chains over yet. . i mean, i think it is happening but this shit takes a long time to fall out. it takes years to setup all the materials needed to create this stuff. it takes years to make substantial changes to them while they use up old stock, design new shit and then have to modify assemply a resource changes to get that stuff. and thats years before it hits your shelf.
i think there also might be a ceiling to usbc.. my thinkpad lappy has a 230w power supply. can usb-c do that?
at some point (we may already be there) usbc components will be so ubiquitous where it matters in manufacturing regions that youll see literally everything under a certain voltage using it
my thinkpad lappy has a 230w power supply. can usb-c do that?
The latest USB-C Power Delivery Standard should do 240w, but not all USB-C ports are rated for it.
There's almost no support for PD that high yet across devices. It will definitely take some time to roll out. The only laptop I know that supports it is the Framework 16, and it requires an extra purchase of a $150 charger.
Nor are a lot of cables. 100W is far more likely, at least for a while, since that was a standard for a fair while as it is.
Money, it’s hard to beat a barrel jack when it comes to economies of scale
And durability.
I have a not-that-old work laptop with a single usb-c charge port (for the dock) and the connection sucks. Thankfully that one also has a barrel jack for power.
I hate that my new one is usb-c only. I'm moving between locations often enough that long-term durability is a concern having to plug/unplug that one all the time. I'd much rather it was an extra few mm thicker and have a charge port I'll never have to worry about.
I have to admit I’m pretty ignorant in low-end laptops.
Business class laptops tend to be able to charge at 100W over USB-C, but often have a dedicated charging port as well (Magsafe for Apple, rectangular charge port for Lenovo, for example).
For any laptop that draws 100W or less, I believe they’re required to charge over USB-C in the EU. Barrel jack is cheaper though, so they can shave a couple of dollars off the price by using it, which could lead to significant profits in increased sales, since most of the competition is using the same basic parts.
