BD82HM65 Intel SLJ8C Vs SLJ4P

[pabloroggeri]

Hello friends:

ThinkPad S230
Mother: LA-8671P REV 1A

Does anyone know the difference between these chipsets and if they can be replaced with each other? Does anyone have experience swapping one for the other.

I have doubts about my PCH BD82HM65 (SLJ8C), the 32.768Khz crystal does not work.

In its place I put a BD82HM65 (SLJ4P). With this new PCH the RTC crystal does oscillate but the equipment in general does not start.

Comparing diagrams, the SLJ4P and SLJ8C use the same pins, but I don't know what the difference would be and if that's why it doesn't work.

Both are BD82HM65, but one is SLJ4P and the other SLJ8C. I would like to know the differences and if they are replaceable, if anyone had experience

SLJ8C is HM77 not HM65.

Thanks for answering

I don't know how my confusion arose. However, the pins remain the same, I compared the diagram of the laptop that I am repairing with the diagram of the motherboard from which I took the PCH, if there is any difference I don't know what it is, since even the RTC crystal oscillates with the replacement PCH that has different nomeclature.

Excuse my English, I use Googlr translator

6-series vs. 7-series. I don't know how good the backward compatibility is, maybe it depends on the BIOS.
In any case, 6-series does not support USB 3.
