#1 HP 14-ca3003na - identyfikacja elementów

by krzysztof000 • 24 May 2024, 19:45
Witam,

Model laptopa: HP 14-ca3003na
Model płyty: G7AL-2G DAG7ALMB8C0 Rev:C

Mam wrażenie, że na płycie głównej w okolicy n.2 i n.3 kości biosu brakuje rezystorów.
Ktoś grzebał przy biosie i musiał coś zdmuchnąć w okolicy.

Załączam zdjęcie jak to u mnie wygląda:

Czy ktoś może umieścić zdjęcie wyraźnej jakości w okolicy biosu jak to powinno wyglądać i o jakich parametrach rezystorów brakuje?

Dziękuję za pomoc.

Hello!

The missing components are probably as follows:
Image
A= R5609 - Resistor 33Ω/5%, package 0201
B= R5621 - Resistor 15Ω/1%, package 0201
C= R5620 - Factory not soldered to the board

The schematic for this board is currently unavailable, just BoardView without the component values, so I concluded their values based on similar boards.

It's connected to the pads marked in yellow.

A bez tych brakujących rezystorów płyta powinna się uruchomić?

Certainly not.
