    A1530 X on battery not charging, off when unplgd,FOUND ISSUE just need to Identify.

    Hi guys , After a couple Hours at cleaning, reflowing/retouching corroted spots, and even repaired/reconstructed trackpad ribbon cable because the mouse was out, would not move. So NO NEED TO BUY NEW BATTERY OR TRACKPAD
    Long story short, im gonna attach photos of this little bugger that took me a while to find.
    Please let me know specifications or datasheet to see if i can replace with somthing else, all suggestions are welcome.
    By the way there is no shematic for the battery pack board 820-3503-A, had Shorts everywhere, so must've taken about 7 components that looked critical on its circuitry, i almost gave up.
    anyways, any input is appreciated!

          Never mind guys, even though the battery is now putting out 10.40 approx, it still shows the interrogation triangle, so something else must be off. i guess ill check the current sensing and the charging ic.

              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...

              Alienware 15 R2 Service Tag: DL7NN32 ISSUE (Battery is not charging)
              by Simone Vergani
              Hello everyone,

              I'm experiencing an issue with my Alienware 15 R2 (Service Tag: DL7NN32). The laptop works perfectly when connected to the AC adapter — it powers on and functions normally. However, the battery does not charge. If I disconnect the DC adapter, the laptop shuts down immediately, as the battery is at 0%. I have replaced the battery with a new compatible one, but the issue persists. I also replaced the AC adapter with a compatible one, but the battery still doesn't charge.

              To assist with troubleshooting, I'm attaching two power circuit schematics:

              HP ProBook 445 G8 Battery not charging
              by Julian Bailey
              Hi all

              We have in a HP ProBook 445 G8 laptop with AMD Ryzen 7 CPU. When power is connected the power LED light blinks 5 times then stops. Normally HP laptops will blink this LED 10 times as it does a self test when the AC adaptor is inserted. So there must be some sort of short somewhere.

              The battery doesn't charge, and is erratic on the MM voltage. Bench PSU LED pulsates when the battery is connected also. So the fault must be on the charging circuit?

              I have gone around the board with a MM and cant find anything

              Windows shows the battery fine,...

              Laptop battery charging circuit
              by piernov
              1. Some theory
              1.1. Introduction
              Almost every laptop has a charging circuit of some sort, that does a few things:
              • Manages switching between AC adapter and battery power
              • Manages battery charging and generates power rail to charge battery


              There are 2 different designs to handle switching between AC adapter and battery power and feeding the system:
              • Hybrid power boost (HPB) and traditional circuits without power boost (see Warning in HPB section)
              • Narrow VDC (NVDC)

              Texas instrument has a nice overview of these technologies with some more details at https:...

              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
              ...
