Laptop jak w temacie mam tylko 5V na cewce PL4551. Pod termowizją grzeje się układ PU4501 oraz D4305, D4307 oraz dwa elementy oznaczone na fotografii oraz PD4406.

Co mogę zmierzyć ?

Measure the resistance to ground on pin 13 of PU4501.
Measure the resistance to ground of PL4501.

PU4501. ma 12 pinów. Czy chodziło o pin1 orazpin3 ?
pin1 brak skazań
pin3 6MΩ i spada
resistance to ground of PL4501 5kΩ

Measure the resistances to ground on listed pins:
- On pin 3 of diodes D4305, D4307, Q2501 (don't ask me why the designation of this diode is Qxxx and not Dxxx).
- On pin 1 of transistor Q2507.
- On pin 17 of chip PU4401.

Measure the power consumption (in mA) of the board without battery connected.

I mean the power consumption on the USB type-C power supply without main battery connected.
Also specify the voltage on the USB type-C power supply.

This power consumption is definitely too high.

Open (cut) the jumper PR4519 and remeasure the power consumption of the board.

Does the chip PU4501 still heat up with the jumper PR4519 opened?

Inject 3.3V from the laboratory power supply to the system side (pad 2 - "3D3V_AUX_S5") of the jumper PR4519. What electrical current flows from the laboratory power supply during the test?
