    KLVL-WDH9Q Matebook NB2686_MB_V5 power issue

    Hello,
    So I have the notebook of the title and has no power issue.
    It takes 20V from the usb-c but it doesn't open the first mosfet at the charging circuit.
    The is no short measuring at the stunt resistor after the mosfets nor any of the mosfets meter shorted.
    The are no schematics and I'm unable to find the responsible charging ic that controls the mosfets, also tried with continuity test to find any connected ic to the gate of the mosfets.
    For sure it is not one from the BQ24xxx series.
    Anyone had the same issue or knows the which is the charging ic?

              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...

              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)...
