    Dell G5 5505 SE Shutdowns on Battery

    Having some issues with this dell gaming laptop, works perfectly fine with charger plugged in.

    Battery health is good, also tried with a new battery which is 93% healthy.

    On battery only will turn on but as soon as you put a load on it will completely shut down.

    Flashed latest bios, reset cmos etc software side seems fine.

    Any ideas?

    I noticed the two chips on the left get warm when plugged into charger, I assume responsible for charging battery.

    The chip on the right, hits about 45c when just using the battery. (No charger). Before it then shuts off.

    Is this normal?

      Check first your first and second mosfet for internal short . That is most common issue. How much voltage do you have on the gate from the first and second mosfet?

            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...

            ISL88739AHRZ ISL88739 Laptop Battery Charger Datasheet
            by Document Archive
            The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
            configurable for operating as either a Hybrid Power Boost (HPB)
            charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
            4-cell batteries. Both configurations allow the battery to work with
            the adapter together to supply the system load when it exceeds
            the adapter capability, referred to as system Turbo mode. HPB
            charger configuration reverse-boosts battery energy to the system
            bus to help the adapter provide the system power in Turbo mode.
            NVDC charger configuration...

            Highly Integrated Narrow VDC Battery Charger for Notebook Computers

            The ISL6257HRZ ISL6257HRZ-T is a highly integrated battery charger controller
            for Li-Ion/Li-Ion polymer batteries. ISL6257 is designed for
            Narrow VDC applications where the system power source is
            either the battery pack or the regulated output of the charger.
            This makes the max voltage to the system equal to the max
            battery voltage instead of the max adapter voltage. Operating
            at lower system voltage can improve...

            Bauer tool battery pack charging with a HERCULES charger modification
            by sam_sam_sam
            The Bauer power tool battery charger just has to many issues with the charger over heating because I several HERCULES Hercules battery chargers that are 3 amp charge and because they have gone on quite a few times over the years before they came out with the fan cooling battery charger I going to modify one so I can charge Bauer battery packs faster than the crape battery charger that they have

            Here is how this modification is going to be done I taking a 1.5 amp hour battery enclosure and gutting it removing the battery cells and replacing some Ryobi 1.5 amp hour battery pack that...

            Milwaukee M18 HD12.0 (12 amp hour battery pack) unbalanced failure charger refusing
            by sam_sam_sam
            I have two Milwaukee 12 amp hours battery packs that have an issue with battery cells very unbalanced these are probably over 4 years old and been heavily used in the past but now get occasionally used heavily and when I went to use the grinder tool the battery lost battery battery power very quickly so I decided to open it up and found some battery cells voltage from 3.6 to 4.1 no wonder the battery charger was not fully charging them 3 out of 4 LEDs were on meaning that it was only 75% charged

            So I have put them on the battery testing machine to drain each battery cell down to...
