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 all, I've been trying to find some information about this 2024 DELL XPS 9730 Have found absolutely no board views or schematics anywhere.
The laptop suffered some minor water damage around a power mosfet which I cleaned up and replaced. From what I can tell that p channel power mosfet source receives a 12V rail when a power supply is connected but its not passing voltage through the drain.
When I plug in the USB C charger with battery removed I'm drawing .2A at 20V
With battery connected it stays at 5V
Under a thermal camera I can see that this component... -
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:

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

I got a Dell Latitude 5420 (Service Tag: 7RFM6D3, Motherboard: GDF40 LA-491P Rev.: 2.0 (A01)) which does not start and I want to repair it. These are the symptoms:
If the laptop is only connected to the AC adapter (battery removed):
When I press the power button, the keyboard backlight and the display backlight are turning on. Caps key light is lightning, but key does not respond to pressing it.
The power/battery... -
I have a Dell Latitude 5530 with a damaged RJ45 network connector. See the attached pictures.
Have already searched on Farnell / Aliexpress / Ebay and had contact with several suppliers on Aliexpress and Ebay, but they cannot deliver this connector.
Is there someone inside the EU, who has these connector(s) or perhaps defective motherboard(s) for these laptop models I have mentioned in the topic title.
