    Yeah, if you read my last post you'll see that I did just that. The PSU functioned normally in the other PC, so my MOBO is definitely to blame.

            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

            lenovo flex 5 14itl05 power sequence issue
            by claws77
            hi guys, my motherboard will not start no matter what
            when connected to ac power, the battery does get charge, led indicator glows red when discharged and turns white as it is fully charged.
            but rest nothing happens no sign of life.

            this laptop has one preexisting usbc power issue - so i use DCIN jack for charging my laptop.
            with this issue my laptop was unable to power ON only sometimes i just had to wait some time.
            but now nothing happens no matter how much i wait/ charge/ press and hold power button.

            i have no knowledge of motherboards ....

            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!...

            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)...
