        let me get a bios battery then! lol

        I noticed a mosfet source and gate gets shorted
        aright after i install a new ine and plug in power? is that normal?

        maybe the issue lies here why the laptop doesnt boot fully..

        tried bios bin file on flash drive and ctr R and nothing comes up..

        Im almlst there hopefully with your expertise i can getbit to work..

          ok tried new bios batt same thing


          there are some mosfets i think on the main 20v ppwer rail, that are measuring 1 ohm between source and gate , switch leads and same thing.. Removed mosfet and still same values on board.. so something on that line is causing that..


          Guys anyone have a the schematic for the board ? GM501GS

                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...

                Lenovo P43s won't boot with internal battery connected – looking for help diagnosing battery issue
                by code share
                Hi everyone,

                I'm having an issue with my Lenovo ThinkPad P43s. The laptop does not power on when the internal battery is connected, but it works fine on AC power alone (battery disconnected). Once the battery is reconnected, the system becomes completely unresponsive — no lights, no fan spin, nothing.

                Here's what I've tried so far:
                • Power/EC reset (held power button for 60 seconds with battery and AC disconnected)
                • Booted successfully on AC power only with the battery disconnected
                • Visual inspection of the battery — no swelling, burn marks, or connector damage
                • Battery
                ...

                HP ELITE X2 1013 G3 weird battery issue
                by huzo
                Hi, so the old battery was getting error stated it's capacity is starting too get low and should be replaced, so the customer bought a new one and replaced it, but the new battery was also getting this notice that it's capacity is getting low and should be replaced, so i took the laptop for testing and the battery is charging at the terminal at 8.03V , the voltage of the battery is 7.7V, and drawing around 600mA when charger is put and the laptop is off...so that should be ok... but the bios system test doesn't recognize the battery and can't do the battery test and so is the hp battery manager,...

                Dell Inspiron 3542 (Cedar_Intel-MB 13269-1) - RTC battery self-discharging and Realtek LAN issue
                by danielsak
                Hello, I have issue with Dell Inspiron 3542.

                Motherboard marking:
                Code:
                Cedar_Intel-MB 13269-1
                PWB FX3MC REV: A00
                The laptop works just fine (on battery and power supply) and doesn't cause any problems, except those described below:
                1. The first problem is that the RTC/CMOS battery self-discharges after about 2-3 weeks after installing a new battery. I have been installing different batteries (GP, Duracell, Energizer) and the problem still exist.
                1. The second problem is the LAN network card (Realtek RTL8106E), which is not detected at all in Windows. The BIOS is
                ...

                Asus TUF won’t run off battery
                by rob777
                I have an Asus TUF machine that doesn't run off battery. Runs off charger ok, shows orange battery charging light and shows battery is at 96%. Battery voltage is less than 0.5v though. It had a short on the 20v rail from a dead cap. Pic attached. Removed cap and replaced a dc in mosfet. Machine now powers and runs fine.
                I have also replaced all 3 battery mosfets with no change. The 1st battery mosfet has 20v going in. Pic attached.
                Does it sound like a battery ic problem, it has bq2470. Not sure if I should replace that as well at this stage as I'd need to order one.
                Thanks....
