    BD82HM65 Intel SLJ8C Vs SLJ4P

    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.

          Hello friends,

          Its been a while, i wish you an happy new year 2025 !

          I have this laptop doesn't start, power light up a second when pluging USB-C charger.
          Laptop take 0.11A.
          All signals and voltages before SLP_S4# are OK but no SLP_S4# , S3...

          I get no oscilation on XTAL 32.768 KHZ
          Battery is not charging but charging led is here.
          PCH heat at 30° approximatively. (with no heatsink)

          I think this crystal might be dead, i have only boardview giving me this: XTAL 32.768KHZ 12.5PF/20PPM.
          It's a 2 pins Crystal.

          Zotac GTX 1050 Ti Mini ZT-P10510A-10L Replacement Crystal
          by OakleyDAR
          HI,

          I'm looking to replace the 27MHz crystal on this board as it isn't generating the signal. I thought it would be easy to identify a suitable replacement as there are clear markings on the crystal, but it appears I was wrong as Google gives nothing. Bad photo attached, but it has X27.0000 and 16AP1 on the casing. It appears to be a 3225 package, but looking through suppliers there are lots of different things like capacitance, tolerance, active or passive, etc. that need to be considered. Could anyone help identify a suitable replacement please?

          Thanks....

          Question on microprocessor crystal oscillator circuit
          by Keshenatech1
          I'm troubleshooting a reel controller board for an IGT slot machine. The digital section seems to be dead. There is no USB communication, PC or utility program for flashing firmware do not see it but they do see good/working boards. I noticed the waveform on the crystal is very erratic/asymmetrical/glitchy on the bad one compared to the nice even waveform on a good board. My question is would this most likely be caused by a bad crystal or something gone bad in the circuit loading it down? I'm attaching a couple pictures of my scope probing the good and bad boads.

          Need help identifying crystal
          by jons
          Got VW Bosch ECU with rotted away crystal oscillator and can't find frequency for it, it drives Bosch 30302 chip for which there is also no any datasheet. Markings on it says
          453NDK9X.
          and there is nothing on internets about it that I can find....

          Samsung Crystal UHD CU7000
          by brewers1212
          I have an 85" Samsung Crystal UHD CU7000 tv, model code UN85CU7000FXZA. When turning on the television the screen has the attached images. It looks like there was an impact point on the upper right of the tv screen.
          Is this some thing that is either fixable? or would be able to find replacement parts for?...
