I have a recently died Microsoft Surface Laptop 3, not battery but mainboard. I’m thinking of a 13" Framework replacement.
I’m wondering if I can use the MS charger with a USB C plug. The charger is 65W at 15v output. I don’t think it has any specific signalling from the laptop. The connector has 2 sets of 3 pins. From cord end +ve nil -ve then a 1mm gap to -ve nil +ve.
The FW13 requires a USB PD power supply with a USB-C plug. If the power supply is not USB PD then it should follow normal USB specifications for a “dumb” charger, 5V at a maximum of 3A. Anything other than this is non-standard and if the port gets 15V without any PD negotiation first it will trigger the USB overcurrent protection if you’re lucky. If you’re unlucky it will fry the port!
So unless this power supply is USB PD, please don’t try it.

Thanks everyone.
I rarely, if ever, used the SL3 touchscreen. But I did like the USB A output on the SL3 PSU.
It is only 5v 1A, but good enough to keep phone going.

I don’t think USB-PD is posssible on anything other than USB-C.
