Hello everyone,
I need the EC firmware dump for Dell Latitude 5420, motherboard GDF40 LA-K491P Rev 3.0 (A02).
The embedded controller is MEC5107-LJ (UE1).
The EC flash chip is W25Q80DV, 8Mbit (1MB).
I already have the 32MB BIOS dump (W25Q256JV), but my system is still not powering on — just amber blink. I suspect the EC firmware is missing or corrupted.
If anyone has this board and can share their EC dump from the 25Q80DV, I’d be very grateful.
Thank you in advance!... -
I need to get a bin/rom file from a Dell bios to modify, I have run into a PFS extractor in this forum. When i run the path it just says "Working... Done!" but no file is created.
I need to open it in UEFITool and exe or rcv file is not supported.
Model: Dell Optiplex 3090 SFF
Service Tag: DQKR0N3
Motherboard Model: Q470
Here is the link of the uefi/bios:

I think it's an 1650 or 1660 NVidia card.
In my infinite wisdom I thought I was replacing the BIOS chip ( one board wasn´t able to store the service tag ) but I saw now that it was the UV 31 chip I tried to replace not the actual BIOS UV 8.
I got on to that via : https://***********/threads/xps-15-9500-la-j191p.41086/
The UV31 chip is mentioned there, I was unable to take it off in one piece from the working board... -
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...
