    DELL 2405FPW - Dead - Fixed

    I hope this may help somebody. I had a 2405FPW that was in a bad way.

    Usual failure mode: Open circuit C605. Cascade failure ensues.

    It is working now. There was some parts that were definitely bad, and some parts that tested OK. There were some parts that I just did not feel comfortable proceeding without replacing them.

    Note: the attached circuit diagram is for a 2407. That said, the similarities between the 2405 and 2407 PSUs are very handy. Check my comments in the PDF to see what I found.

    Good luck, these PSUs generally will work again with a little love.

      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 dockstation WD15 is dead
      by Francesc V.
      Hi:

      A friend gave me this DELL WD15 dockstation that does nothing. Not detected by computer, no digital output.........just leds shines when it’s plugged in.
      Here are the findings, followed by good pictures. :-)

      When pluged in, LED3 glows
      Measuring some voltage in the circuit.


      Inductors
      - PL202 has 5V
      - PL201 has 3.3V
      - PL300 has 1V

      V. Regulators
      - UT30 has 19v as input and 6V as output. It seems ok.
      - UT27 (same reference as UT30, has no input/output voltage).


      Thermal find...

      DELL Latitude 5410 - dead; pwrbtn flashing
      by YellowJacket
      Hi folks,
      DELL Latitude 5410, board number FDZ41 LA-J371P Rev: 1.0 (A00), schematic uploaded in different post, here is the link --> https://www.badcaps.net/filedata/fetch?id=3484415

      When I connect it to a power ( DELL round charger, or USB-C ), LED on the power button starts flashing white, and the laptop doesn't do anything ( flashing slows for a very brief time in time when I press it, but it continues again ). Battery is not charging. While the charger is connected, I have few voltages present, but some of them are fluctuating, see attached pictures.
      All I was able...

      Dell 3080 Micro BIOS dead
      by tracks
      Hello all,

      I have a Dell 3080 Micro with a problem. As it is right now, it seems to be boot looping, maybe... There's no output, just fan on and power led lights up and blinks off every 2 seconds or so.
      Previous owner told me he bought it with a BIOS password, he tried to use a CH341A programmer with some random test clip and tried to mess with it while it was powered on. Now it won't boot.

      I tried to dump the bios with an EZP2023+ but I can't get a consistent read. Every time the dump is different, so it's unusable. I think the BIOS chip is fried.

      Dell E6540 laptop completely dead after dssasembly
      by max-power
      Hi, I disassemble my laptop to replace the speakers, to access them, you have to remove everything including the heat sink and fan, unscrew the motherboard, lift it up a bit to access the speaker wire.
      that was not the first time I dissasemble it, i did replace the same speaker a few year ago and I repaste it last year, so I had nothing to worry about. but when I put everything back together, its completely dead.

      After a bit of investigating, i found one pin of the status led ribbon cable that was unglued from the cable and bend touching another pin, I bend it back at his place...
