    Asus UX533FD no power
    by smic717394
    Hi guys, I need a bit of help, I have a Asus Zenbook with motherboard UX533FD Rev 2.1. Connecting the laptop draws 30mah and not coming on, Measuring the coils I got the values below. Measuring in resistance all coils have normal values, cpu about 8ohm and the gpu about 5ohm but I guess its normal. Checking with the thermal camera, the only 2 chips that have a bit of heat signature are the U3501 (pd controller) and the U3001 that is the KBC. Now I guess the PD controller it's not the the problem because the battery is fully charged and trying to turn on on battery is the same.

    Dell Latitude 5570 Ambient thermal sensor reading -127 Degrees C
    by Gcnewbie
    Forgive me this is my first request for help on this forum, so if i've screwed up or not followed the rules i should have i apologise profusely.

    I have a Dell Latitude 5570 that was randomly shutting down, on further investigation i found that the machine had been shutting down due to thermal events as noted by windows event viewer.
    My investigations lead me to the dell diagnostics screen, where i found that there were two sensors out of range which had been causing the shutdowns, one of which was the GPU thermal sensor and the other the ambient sensor.

    Dell Vostro 3420 BIOS Password Removal
    by sammus540
    I have a Vostro 3420 8H8K5R3​-8FC8 that freeze at any attempt to enter bios password or the recovery master password received from dell. I do not have a clean BIOS image to flash.
    And as luck would have it happened a couple of months ago right outside of the warranty period (Dec 2023) warranty expired in September. Any help or guidance is appreciated.

    ThinkPad X270 (NM-B061) no POST
    by rumpumpel1
    I have a ThinkPad X270 (NM-B061) with the following error: the mainboard tries to start, the current goes up to 80 mA and then immediately drops back down to 20 mA. This is repeated every few seconds. Fortunately, there is a timing diagram at the end of the schematic. Starting from the top up to and including -PWRSW_EC it is all as shown in the diagram. Starting with -PCH_SLP_S4 you can see the periodic behavior, i.e. instead of the signal staying at 3.3V, it always drops back to 0. What conclusions can I draw from this behavior?

    LG 49LJ550M-UB Looking to do some mods
    by KxngCrooked8
    Hello,

    I have an old(er) LG 49LJ550M-UB that I'm looking to convert into a light source/audio player.

    The only issue I'm currently experiencing is that I can't get the LED's to stay on permanently. I still have the intact LCD panel and have fiddled with all of the settings trying to get the LEDs to stay on with no luck. In lieu of that working, I'm hoping to trick the power board into keeping the LED's on. I think that I've found the correct signal that I need to send, >3V to the PDIM pin on the P201 connector on the power board. But I'm not sure where to grab...

    Lg oled55b8 t-con question
    by reassor
    There is 2 sia ics and in 1 section where u see dots on the coils i have 2.2ohm there and there is no voltage on them at all.

    Also i read in other topić how psu works on these tvs and when u pług it in there is constant 40w draw from wall. When I unplug display from tcon it drops 10w when I unplug tcon it drops another 10w (unplug done w/o power ).

    I'm mostly sure its main board cpu cause no sygnał to turn on 24 volt for panel and its constant draw.

    For now I'm just curios about these w coils . Could not find any datasheet for ic thats the lines go...
