      You can take any N-Channel mosfets from power supply circuits that fit the size on that battery. Remember to replace both of them

          Locate the charger ic and share the topside mosfet markings.

                  Strange battery present behaviour in Lenovo Legion 5-15ARH05 mb model nm-d041
                  by ferah831208
                  Hello guys, i need help with this problem, I have a NM-D041 mobo, it came with low impedance in 3v linear regulator rail, the cause was a damaged EC controller ITE8227e-192. I ordered a new one and replaced it. This laptop have a different chip for keyboard management and it8227e pins for programming ITE chips are not accesible through keyboard interface, I flashed it using i2c interface pins with vertyanov programmer because laptop was dead and SPI flash didn't have power (only 3v EC) so it couldn't access firmware stored in SPI memory. I read SPI and extracted it8227 firmware from original BIOS...

                  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
                  ...

                  Lenovo Yoga C930-13IKB EYG70 NM-B741 Battery not detected.
                  by mrkmpn
                  Hello, I have a customer that brought this laptop in after replacing his battery. He said his original battery charge was not lasting long, and after replacing the battery with one purchased from iFixit, the charging worked for about 30 minutes and then stopped, and the battery is no longer detected by windows.

                  This laptop powers on when the AC adapter is connected, and my USB-C multimeter shows current being used with both ports, but the charging light does not come on, and in Windows the battery icon shows an X as if there is no battery present. If I disconnect the AC adapter,...

                  Lenovo V310-15ISK - It doesn't work after changing the battery
                  by pabloroggeri
                  Good guys. I changed the battery to a Lenovo V310-15ISK.

                  The laptop worked perfectly, I changed the L15C4A02 battery because it didn't last very long.
                  When I connected the new battery, the charging LED stopped lighting up and the one next to the charging pin also did not react when I pressed the power button. Minutes before changing the battery it worked perfectly and stopped working after putting the new one in. Even if you put the oroginal battery in or connect it without the battery, no LED lights up when you press the power button nor does it give an image, nor does the...
