    Dell G15 Ryzen Edition Display's on External Only

    Good day, BadCaps Technician Team,

    I hope this finds you well.

    I am reaching out for assistance with a Dell G15 Ryzen Edition laptop that I am currently troubleshooting.

    The laptop successfully posts on an external screen, but the main screen remains unresponsive. Below are the steps I have taken so far:
    1. Ordered and replaced the LCD panel and LCD cable.
    2. Verified that the 19V power rail for the backlight is present.

    Despite these efforts, the main screen still does not post. I am unsure of the next steps to identify and resolve the issue.

    To aid in the diagnosis, I have attached the schematic and board viewer files for reference.

    Could you please advise on additional areas or components to check?

    I am particularly curious if the issue might relate to:
    • The LCD connector on the motherboard, such as damaged pins or loose solder joints.
    • A potential fault in the eDP circuit (embedded DisplayPort).
    • Possible firmware or GPU-related issues.

    I appreciate your expertise and guidance on this matter. If any additional details or measurements are required, please let me know.

    Looking forward to your response.

    Seeking boardview+schematics for Dell G15 5515 Ryzen Edition LA-K453p
    by trepachka
    Model: Dell G15 5515 Ryzen Edition
    Motherboard: LA-K453p
    Service Tag# 838W8R3

    Computer is currently dead, 20V doesn't go beyond the first 2 mosfets as there is 0V on the gate. My next order of business would be to find the charging circuit, ie the charging chip.

    It would be great if someone uploaded boardview+schematics for it.

    Thanks.

    Good day, I bought a laptop, thinking the screen was broken. But it turned out that wasn't the problem. The laptop shows an error with 2 red lights and 7 blue lights.
    I read that for many people this is related to the BIOS. Could someone check if this is the case with my BIOS file? And fix it....

    DELL G15 RYZEN EDITION LA-K454P disable gpu
    by PacoGT
    Hi friends, I have a problem with this laptop. It gives me a processor error, but when I measure the processor, it has power, heats up, etc.
    But at first I thought maybe it was the BIOS. I tried reprogramming it, but nothing.
    After that, I measured the graphics card and realized that the graphics card has no power.
    So I lifted the power coils and checked that there is power, but when it reaches the GPU, they go to ground.

    With a thermal camera, I realized that it apparently has a short in a VRAM. After removing the short, it goes to the GPU.
    So my question...

    Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
    by Bowline
    My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

    Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

    My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
    The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
    I have tried multiple different Dell power adapters. My Dell...
