    DA0R23MB6D0 power issue

    The laptop had no power issue [no 3 or 5V].
    After replacing kbc KB3930QF system could power on but had no power at cpu - vga coils.
    Also replaced southbridge 218-0755046 and now I have power but no signal.
    I have one blink at caps lock that means cpu no funcional.
    As far as I can remember I have tested the cpu elsewhere and worked.
    Also tryied another bios but with no luck.
    Any suggetions?

    If you are sure that the bga seated correctly and was new and working then try to clean the cpu socket. Sometimes gets oxidised during heating process. Also try different ram sockets, on some mainboards the first ram must be on the upper ram socket.

      I did a good clean at the cpu socket with no luck.
      Also tried different ram compilations.
      I reinstalled the southbridge with leaded balls and reballed the vga.
      Seems to be a hard one to get it work.

        Asus Probook P5440UF-XB74 power issue
        by GLISIT
        Hi all,

        TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


        I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

        A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

        Acer Spin 1 SP111-33 Power-On Issue (Troubleshooting Assistance)
        by justice171
        I am seeking guidance on an Acer Spin 1 SP111-33 that does not turn on when pressing the power button.

        Below are the observations and troubleshooting steps I have taken so far: Observations and Tests:
        1. Verified that all critical voltages are present:
          • 3.3V and 5V are always present if DC is plugged.
          • 1.8V on the BIOS chip is present.
        2. Checked the power button functionality:
          • When pressed, the voltage drops to 0V, indicating the button is functional.
        3. Inspected the flex cable connecting the USB, audio, and power button to JUB1:
          • Confirmed connectivity is intact, ruling out issues

        but now nothing happens no matter how much i wait/ charge/ press and hold power button.

        Dell G3 17 3779 Weird power cycling and shutdown/restart issue
        by SuperJames
        This one's a weird one, and still unsolved despite it having gone back to Dell once.

        Specs

        i7-8750H, GTX 1060 Max Q, 500GB SSD & Seagate 7mm 1TB HDD. 17.3 IPS screen. This has the fingerprint reader in the power button.

        Backstory

        I bought this from eBay, from a wallpapering shop. £650 in 2020 which was a good price considering it's a gaming laptop. Physically it's in perfect shape, apart from the hinge mounts on the palmrest failing in the time I've had it (I have a new palmrest for it). The usual thin plastic crap modern build quality!...
