      Is the MB power up with the Battery? What is the Voltage on PQ308A pin2? Voltage on PD301 pin2?

          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
          ...
