    I assume you've having quanta u88m, so schematic not available. check if PD7 and PQ21 has shorted.

    attached datasheet and photo as reference

                          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
                          ...

                          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. Β£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!...

                          Samsug washing machine. Power supply DC41-00189a board issue
                          by Soulzink
                          Hi everyone,

                          I am trying to fix a samsung washinmachine power supply main board.
                          I already replaced it with another one to fix the machine but i want to try understand the issue with the old board.
                          Therefore i hope to be able to get some help to explain what to check in order to troubleshoot.
                          The power supply board reference is the following: DC41-00189a
                          I have followed one thread (https://www.badcaps.net/forum/troubl...ingmachine-rel...

                          LG 42LB5D, 42LB5DF-UL, 2008-01, Power On Issue, Replaced PS Caps
                          by bcstedt
                          LG 42LB5D (42LB5DF-UL) from 2008-01, unit is in good shape and no obvious heat damage or cracked solder on the boards.

                          Problem:
                          On first power-up the power LED flashes green about 18x and then stays solid. No backlight or image is present. Click power button, wait 10s for a click and the LED turns red. Wait 1-2s and hit power again and maybe it'll power up fully after 6 green flashes. If it doesn't light up on the sixth flash then the cycle repeats.

                          It seems that if the mainboard power is left on for a few minutes (solid green power, no backlight, no image)...
