    Dell Vostro 15 3000 (i5-11th Gen) 3 Orange 5 White LED Code

    When plugging in the laptop the LED charger light stays on solid white for about 30 seconds then it starts blinking first 3 orange then 5 white.

    There was a short to ground on the +5VS rail which I solved by swapping UZ2 (from schematic which is attached) chip and the fan connector capacitor which was shorted to ground. However this didn't fix the issue as it still happens.

    This is about as far as I have gotten with the repair as I can't see any other issues.

    Please let me know some things I can try or things I need to check.

    Thank you!

    Extra Info
    Motherboard details: GDI5A LA-K033P
    Schematic says Dell inspiron however it is the same board as the vostro

    Review the voltage to ground of emi ferrite @ PL3. This is inline with the PS_ID single wire communication line used by the SIO controller (8051) to extract vitals out of the Dell power supply. If this communication line fails, the logic board will be unable to validate the power adapter.

    PS: Best to move your schematic inside the schematics forum.

        Try RTC reset.

          Have already tried all basic things like removing RAM, Wi-Fi card and all other connectors.
          Tried the motherboard itself outside the chassis and still same thing.

              Dell usually dont have light on dc-jack. To me it seems like mb is getting powerd on and then indicating an error code. Measure voltage on all coils so that you can get an idea whether its triggered or not. If you have dc supply,mention the power consumption.

              Have you flashed bios? Worth a try.

                https://www.dell.com/support/kbdoc/e...tablet-systems

                Error code lines up with missing power rail. So go through all your rails (and PG's back to the EC). There is a sequence on pg 4 you can follow for each PM_SLP state.

                BTW, anyone notice on pg 96, the protection circuit is titled as "No Smoke". See they do have a sense of humour at Compal

                  I have measured voltages to ground on coils and listed them below, I have took a photo of locations on the board and colour coded.

                  PL301 (Red): 3.37V
                  PLM01 (Yellow): 1.18V
                  PL501 (Pink): 5.18V
                  PLV02 (White): 0V
                  PLV03 (White): 0V
                  PLW01 (Dark blue): 0V
                  PLZ01 (Green): 0V
                  PLZ02 (Green): 0V
                  PL1801 (Light blue): 1.8V
                  PLG2 (Black): 1.82V
                  PLB01 (Orange/Light Red): 0.5V

                    Your CPU doesn't get voltage at all. Measure tesistance to GND of PLZ01 or PLZ02

                      Hi thanks for fast reply, I checked both 01 and 02 and got 77 ohms to ground each side

                          We should start from the RAM controller, so whether 1.2V_VTT_PWRGD is asserted ( PUM1 Pin 10), then whether the 3VS and 5VS are present at UZ2 Pin8/9 and 13/14. From there ALL_SYS_PWRGD and IMVP_VR_ON_P should be available.

                            Hi, I have checked on UZ2 and it gets the 5V and 3V in however it outputs very low voltage, 0.5V on +5VS and 0.2 on +3VS.

                            I am not sure how to tell which pin is 10th pin on PUM01, I think I found it and got 0V could be wrong tho

                                Not sure if you wanted UZ2 or PUM01 so I took a few pictures. You can see both chips in last picture.

                                      Something is wrong there. Measure whether 0.6VSP is present at PUM01 Pin20. Check the Enable too, Pin7
