      Re: DELL 3558 NOT GETTING ON

      Which charger ic it uses?? On some charger ic, acok is pulled low and so it should be zero. So do check with charger ic datasheet as schematic is probably unavailable. You can trace the rtc circuit with a multimeter with a little bit of effort. RTCRST is must without which it will not turn on.

          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.
