I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.
I started on the ACER:
Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.
I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap... -
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?

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!... -
