- Topic title should contain: the device's manufacturer, full model and the brief description of problem.
- 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.
- Before posting a new topic please read all topics in TRAININGS subforum and make a preliminary diagnostic based on the content of those trainings.
- 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.
- It is only permitted to describe one faulty device per single topic - you should always open a new topic for each subsequent device.
- 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.

if resistance on +3VLP(+3VLP_EC) is not low, there is no need to open JPB1.
With "focus on charger itself..." I was saying that you have to focus on all charger signals...post charger voltages on VCC , ACDET, REGN....check continuity of ACDRV_CHG line and values of corresponding resistors of this line.
Are you testing MB with original power supply?

Tak jak wspomniałem na poczatku postu
Rezystory PRB7 4Ω, no i PRB4 5Ω (powinno być 4,7Ω), ale nie w tym problem charger nie wystawia mi napięcia ACDRV_CHG i sygnału do KBC - ACOK.
Testowałem na zasilaczu oryginalnym i laboratoryjnym.

Wymiana charger'a nie pomogła, efekt taki sam.
