    Asus X555LD ver 3.6 no power

    Hello, I'm having issues with this Notebook, it doesn't power on.All voltages are present, 5v & 3v and no short at any coils.
    It consumes 56 mA when is connected to the power supply and when power button pressed drops to 2mA.

    I have already found a same problem that someone posted in YouTube but I don't understand the language.

    Can anyone translate it please or give me any suggestions?
    Thanks

              I am unable to pick up all of the words of this slang.

              But the actions appear to be:

              1) check the 3*ferrite bead inductors. Are they ok or burnt on your logic board?

              2) he appears to reflash the bios chip he shows in the video. Wait on this step and advice from others.

              update:

              see post # 5 for a clear bios dump (only if required but be sure to backup your original if you proceed)

              https://www.badcaps.net/forum/showth...ghlight=X555LD

              3) believe you are requesting the mosfet question in the post on youtube? Carefully measure the voltage of each pin on the 2*mosfets that follow the 3* inductors on the board.

              Interested in the voltage on:

              Source (1-2-3)
              Gate (4)
              Drain (5-6-7-8)

              Of each mosfet.

              3) what are top side markings of each mosfet?

              4) near these mosfets will be the charger IC. What are the top side markings of the charger 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...

                  Microsoft Surface Pro (5th gen) model 1796 - no power
                  by PantherDave
                  Hi all!

                  I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. πŸ˜…

                  I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

                  ASUS TUF X570-PLUS doesn't power on: no VRM_EN signal.
                  by ShadowAi
                  Hello, I have an issue with the motherboard. Specifically, it doesn't power on, more precisely, the POST initialization doesn't occur.

                  Let me start from the beginning, the motherboard suddenly stopped working one day. There are no beep signals from the speaker, and the debug LEDs are not lighting up. After inspecting it under a microscope and using thermal imaging, I didn't find anything that could be damaged.

                  After that, I began voltage measurements, in which I noticed the absence of VDDQ, VDDP, VTT, and VPP lines. Later, I checked if there is an EN state on these lines,...

                  by meraklinetx
                  Hello, I have an asus Z97-A motherboard and it doesn't start which was working properly before, the problem isn't related by ram, ram slots or psu (I changed all and nothing work), the exact problem is when you switch it on , it starts and after 1 seconds (no boot or display picture) it's off and then on cycle continuously until you power it off from psu also it's responding to the power switch for turning it off if you keep pressing it 3 or 4 seconds (power button pin has 3.3v) , also when you start it with eatx 12v socket connected this is happening (power cycle also all voltages are resetting...

                  Request for Help – ASUS G531GW Rev 1.6 – No Power On

                  Hello everyone,

                  I need your support with an ASUS G531GW Rev 1.6 laptop.

                  When I plug in the charger, the battery charging LED turns on, but the board does not power on when pressing the power button.

                  Here’s what I’ve checked so far:
                  • Motherboard has been removed for inspection.
                  • 3V and 5V always-on rails are present (3V/5V_ALW).
                  • 1.8V and 1.09V at the PCH are present.
                  • I don’t have the boardview/schematic, so troubleshooting is limited.
                  • I tried checking the power button signal from the
                  ...
