    can anyone help identify this chip ?

    after tur on - S0 - 1,80V
    after turn off - S? - 1,10V
    power source pch ?

    after turn off I suppose the board doesn't reach S5 state, battery powered without charger, maintains 3 and 5V and 1.8V voltage, led charging orange if battery charging, white after charge. still white after off without charger.

        Re: Asus F712J

        thank you


        (vid1 == 0 && vid0 == 1)
        { vout = 1,10V; }

        I still don't have a schematic, ic look good , Vout is 1,10V .
        The output voltage is 1.10V because this is how the "vid" inputs are controlled.
        Maybe I will try to reprogram kbc, anyone has a file for kbc for this laptop or extract from bios ?

                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...

                Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                by Tynan Dill
                I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                Upon bringing it home and plugging it up, it showed a standby light.

                I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                The screen seems to blackout and stay black, but with a flashlight I can see the display.

                With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                Assuming...

                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. 😅

                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,...

                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...
