DELL Latitude 5421 schematics

[Youness]

Hi all,

Could you please help me to get the DELL Latitude 5421 schematics and boardview file.
Motherboard is LA-K921P

I have bothe USB C port fried and shorted so it only work on battery.
When I plug the charger, the Led on the charger turns OFF.

I think even same generation dell schematics could help.

Regards

Youness

USB‑C/power‑in section must be the same as LA‑K921P on this Latitude 5421 platform generation

In theory, yes; but the addition of the GPU, VRAM, and power packages mean a lot of the surrounding circuitry has to be moved, removed, or altered. Trying to track lines that go through vias and then to wherever isn't always intuitive, especially when the vias don't always go all the way through the board. So, where as the USB PD controller in K922P has more components around it to handle the extra load, the K921P does not and in fact has other, unrelated components in their place. While this is a good add to my collection, I still need K921P. Thanks.

Thank you R12X2,
Iit's a good begining to start with.
Indeed I aslo noticed that the K921P motherboard is not fully equiped (does not have all the component soldered) .....depending on the options you may purchase I guess.
Now I'm wondering why we still can't find a 2021 laptop schematics VS some others machines more recent?
