Re: Dell 1525 DS2 Intel Tps51120 faulty or not?
Most likely it will work. Pinout of EC if configurable and depends on software.

If you have voltage on power button, and no S5_ENABLE voltage when you press the power button, then either it is the BIOS or the U22 WPC8763LDG-1-GP chip.
Also check voltage rails for short circuits.Comment

Re: Dell 1525 DS2 Intel Tps51120 faulty or not?
Thanks guys, I'm just waiting for the chip and the bios programmer I ordered online. I use to visit my friend for bios reprogram but now I'm gonna get myself one.
I was a little confuse on previous post, I have watch a video from an Indian fellow that S5_ENABLE and RSMRST should only be present when power button is pressed I disregarded that and thought S5_ENABLE is present in S5_state. I will update if anything comes up. I have all my problems solve in this site so I owe it to you guys. Thanks again!Comment

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... -
Hello,
I've purchased 2nd hand Dell Latitude E7470 i7-6600U and it works fine, except ... there are no TPM or TXT/Trusted Execution settings in the BIOS/Firmware. However, looking at the schematics I found the chip handling TPM (NPCT650JA0YX) soldered to the system board. Also, looking at the service tag and the product specifications, this device comes with TPM (and vPro) support (I know that devices sold in China, Russia are not allowed to ship with TPM but this should be reflected in the service tag). I can also login to MBex to configure, etc.
In the produce specs...02-12-2024, 05:21 AM -

If the laptop is only connected to the AC adapter (battery removed):
When I press the power button, the keyboard backlight and the display backlight are turning on. Caps key light is lightning, but key does not respond to pressing it.

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.
