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... -

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

- 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).

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.

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.
