  1. Topic title should contain: the device's manufacturer, full model and the brief description of problem.
  2. Topic message should contain: the PCB marking code (required in case of hardware repairs), an extended description of problem, things you have checked/replaced/measured, your conclusions and the question. If you are not able to find the PCB marking code, please read THIS TOPIC. If you still cannot locate the PCB markings, please upload a clean, both-side photos of the mainboard - it is required to remove any films, modules or brackets possibly covering these markings.
  3. Before posting a new topic please read all topics in TRAININGS subforum and make a preliminary diagnostic based on the content of those trainings.
  4. Uploading of any complete schematics, BIOS / firmware files or any other kind of documentation, or linking to 3rd party websites with such files, is STRICTLY PROHIBITED. You can only upload the small portion of documentation or, link to BIOS file on UNVERIFIED BIOS FILES subforum, which simplifies the diagnostics/repair. You are not allowed to upload more then one complete page of instruction/schematic per single topic. The file you upload must not contain any watermarks, "confidential" markings, links or email addresses and cannot be password-protected.
  5. It is only permitted to describe one faulty device per single topic - you should always open a new topic for each subsequent device.
  6. Requesting of the full schematics, BoardView files, BIOS files or any other kind of documentation is NOT ALLOWED in this subforum. If you need to ask for any of these, you should open a new topic in DOCUMENTATION/BIOS REQUEST subforum.

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 ?

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.

Czy to prawidłowe wartości ?

This power consumption is definitely too high.

Are you sure?
Post a clear picture with visible markings on the chip PU4501.

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?
