Hello,

this is my first post at Badcaps and in general i am new to fixing electronics. I am looking forward to learn a bit more about diagnosing and repairing :-)

What I have around is a DELL OPTIPLEX 3060 Micro (USFF), which is not powering on, even not showing any signs of life (No amber / white LED).
I got a original 65W DELL PSU / Power brick (PA-12 / 074VT4) which hopefull should be the correct one. I could get another DELL PSU with the Partnumber 0G6J41 with the same 4.9mm DC Jack connector as the one I already have, but I dont think that would help (maybe...

Hi, I have a Dell Latitude 5410 motherboard (LA-J37), REV A00 PWB P/N 8578V.

I'm building a custom setup similar to a tablet but without touch capability by attaching this motherboard to the back of a USB-C monitor without the chassis. I have several critical questions before proceeding:

Hi All, I have a 9th Gen Dell Optiplex micro PC motherboard which doesn't power on. When I connect the motherboard with power adapter, it goes into safe mode and turns off.

I am new to electronics repair, so my queries could be naive but I am ready to learn.

So I have a multimeter and a solder with me. But I can try to get a variable voltage power supply with a thermal camera as well. From what I seen online, best way is...

Dell PN of the motherboard is 08DCGW.




Below is the area I am trying to repair:



Does anyone have a picture of this motherboard in this area they could take and upload?

Cheers...

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...
