On the other hand, I have a USB-C charged laptop, but it only accepts one specific spec of 45w, and one specific spec for 60w. This means that 90% of usb-c chargers don't work for it, including chargers that support 45w or 60w charging. This means that even if you buy a charger with the right wattage, its effectively random whether it will work or not.
I have different work Thinkpads from 2019, so probably the first one was 2018 or 2017 generation. And they accepted whatever laptop usb charger (ok, most of them were also Lenovos, but some generic stuff our IT was ordering from Amazon as well)
My current T14 works with my AliExpress 120w powerbank.
Probably good to rely on brands who don't mess with standards
Why did you not use this opportunity to name and shame, to help others avoid such evil manufacturers?
You just note down the company who delivered the idiotic product: next time your options for purchase are narrower, but it narrow the chance to buy products badly designed.
Just because some companies sells USB butplugs it doesn't mean USB standard is necessarily a pain in the ass overall.
I have a fucking thinkpad that does not follow the USB PD spec!
The thing has only type-c ports, the thing is relatively recent (2023), the thing accepts 140W via type-c, I never bothered to check the actual specs and assumed PD 3.1
Turned out that no, this is not PD, this works only via proprietary power brick that outputs 20v@6.75A, that I didn't get as I already have a bajilion of PD 3.0/3.1 power supplies at home.
::: spoiler back of the device
No, but it does mean that the USB standard allows for being a pain in the ass, compatibility-wise, which kind-of defeats the point.
