Dell G3 15 3500 - Battery bug (black screen and flashing keyboard backlight)

by HTR-Informatique

Hello,

YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

I also changed the screen because the PC fell and the screen was broken.

I changed the battery with a new and original battery.

I also had corrosion/oxidation on the...

Looking for Dell Latitude 5520 / 5530 / 5540 RJ45 network connector replacement

by diamon

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.

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 Latitude E7440 battery not charging only works on AC Adapter LA-9591P

by Grucha98

Hi, i have problem with dell E7440, battery is not charging. Idk all story. Original Dell Adapter broken up (its not give 19V) i guess first ac adapter broken up and it broken charging circuit in laptop. Laptop has clone battery (Green Cell)

Laptop works on clone adapter, and its not charging battery. Like on photo. I checked mosfets near battery plug. They are not shorted. But on PQ809 and PQ810 are low on diode mode (both 0.25V) I desoldered them and check on bench and they are good both 0.5V on diode mode. I checked only drain - source way. So its board circuit it should be higher,...
