    now i have new problem with this laptop display becomes WHITE screen, already done replaced with new lvds cable still the same issue, replaced with new screen same issue, i have check on the schematic the LCDVCC is missing on pin23 on lvds connector, and on U26 chip here is the voltages

    PIN1= 0V
    PIN2= 0V
    PIN3= 3.3V
    PIN4= 3.3V
    PIN5= 0V
    PIN6= 3.3V

    Noticed that the out the PIN1 Is the output of the chip because pin 2 and pin 5 is ground.does anyone help me on this to solved this problem please
    Remove U26 ic and measure voltages on all pins again after switching. If everything remains same then jumper pin6 to pin1(without the IC) and your problem is likely to be resolved.

        Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
        by Bowline
        My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

        Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

        My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
        The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
        I have tried multiple different Dell power adapters. My Dell...

        HP ProBook 445 G8 Battery not charging
        by Julian Bailey
        Hi all

        We have in a HP ProBook 445 G8 laptop with AMD Ryzen 7 CPU. When power is connected the power LED light blinks 5 times then stops. Normally HP laptops will blink this LED 10 times as it does a self test when the AC adaptor is inserted. So there must be some sort of short somewhere.

        The battery doesn't charge, and is erratic on the MM voltage. Bench PSU LED pulsates when the battery is connected also. So the fault must be on the charging circuit?

        I have gone around the board with a MM and cant find anything

        Windows shows the battery fine,...

        Laptop battery charging circuit
        by piernov
        1. Some theory
        1.1. Introduction
        Almost every laptop has a charging circuit of some sort, that does a few things:
        • Manages switching between AC adapter and battery power
        • Manages battery charging and generates power rail to charge battery


        There are 2 different designs to handle switching between AC adapter and battery power and feeding the system:
        • Hybrid power boost (HPB) and traditional circuits without power boost (see Warning in HPB section)
        • Narrow VDC (NVDC)

        Texas instrument has a nice overview of these technologies with some more details at https:...

        ThinkBook 15 G3 ACL Not Charging Battery - LA-K602P Board
        by kodox
        since i couldn't find schematic or boardview for this model (LA-K062P), i use closest board model found here https://www.badcaps.net/forum/troubl...-and-boardview

        the schematic share same marking for each component, using same PD-Controller, same BQ25710, the only different is the battery cell used. LA-K061P uses 3S battery while LA-K062P use 4S battery per schematic.
        what i've done:

        Razor Blade Steath 13" RZ09-01963 plugged in Not Charging (new battery)
        by Shinju
        Hey All!

        Long time forum member here with a problematic laptop issue!

        I got a RZ09-0196 with a bloated battery (still worked and charged fine) I pulled the old cell pack out and installed a new cell pack in its place.

        The laptop would not power on with the new battery installed without the power supply being plugged in.

        When booting into Win10 (all up to date BTW) I saw the battery icon with 49% plugged in not charging.

        TL;Dr version, old battery worked, charged but was bloated, installed a new non OEM replacement, laptop/windows...
