      It is on your experience and practice I have done many times ..take a very thin wire solder it and trace the damaged line connect the wire to that component and the other side place under the ic in the burnt area and past with flux and adjust with other line of the ic equally adjust with needle and then place the ic with care and give heat.

          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...

          Dell Inspiron 5590 Board 18778-1 no charging, charging not possible
          by master3112
          I would like to share my experience about charging issues with Dell power supplies with the tech community. I am working on a Dell Inspiron 5590, Mainboard 18778-1 with charging problems. The device can be switched on and works so far, only the message appears at startup:

          Alert! The AC power adapter wattage and Type cannot be determined. The battery may not change. The System will adjust the performace to match the power available.

          The power supply unit is not recognized in the Bios and the charging process is set to "idle". I use original Dell battery, type...

          Dell AC adapter - 1 wire protocol. How to initiate to check if adapter works.
          by Bogdan Kolybaba
          Hi all. Trying to troubleshoot issues with the Dell Laptop power supply (a lot of info here). Now I am waiting for a DC power Jack, as there is a loose contact. Want to check if the ID line of the adapter works - I have given abt 3.2 V to this line through the voltage divider, but can't see any signal on the oscilloscope. Same with the 100500% working AC adapter as well. How to initiate 1-Wire protocol transmission? As I understand, the circuit in the AC adapter should send a package for a while as soon as the supply comes to the SPID line. How to initiate this transmission correctly without...
