Re: Dell la-j081p charging issue
First i would check dcin mosfets for internal short , then i would check if the adapter is recognised in bios.
Then we can go further can you give us link to shematics.
Good luck -

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... -
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:
Alert! The AC power adapter wattage and Type cannot be determined. The battery may not change. The System will adjust the performace to match the power available.
The power supply unit is not recognized in the Bios and the charging process is set to "idle". I use original Dell battery, type... -
Hi guys,
I am working on a Dell G3 3579, with motherboard LA-F611P that is not charging.
Unit was dead with blown PU01 and I replaced PU01 along with PUB02 to get the unit going. After testing I found the unit is not charging.
I have seen this on the Dell G3 3579 on about 5 different units, but I have never been able to fix it
So I can see in the bios its not a charger detection issue, as it is detecting my 130w charger fine, but even when plugged in the battery will show its discharging. Unit works fine from battery and from... -
Hi,
This board is driving me crazy. So it's the usual AC Adaptor not detected in BIOS etc. Battery doesnt charge.
Got a new charging pin, original Dell charger that works, another battery that also works. Still have an issue.
Problem is I am very new to this so I need a very laymans way of explaining to me what I should check.
Thanks Guys
Edit : Board is a LA-J081P -
This one's a weird one, and still unsolved despite it having gone back to Dell once.

Backstory
I bought this from eBay, from a wallpapering shop. £650 in 2020 which was a good price considering it's a gaming laptop. Physically it's in perfect shape, apart from the hinge mounts on the palmrest failing in the time I've had it (I have a new palmrest for it). The usual thin plastic crap modern build quality!...10-23-2023, 04:09 PM
