    Crystal compatibility 32khz ASUS UX325 NB255_PCB_MB_V4

    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.

    Can i replace it with something like this :

    Please find attach a photo of the crystal.

    Thanks.

      Yes. Measure the length x width of the original and compare to the replacement. The loading capacitance is also important to guarantee the clock starts up properly.

              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....

              CD3217B12 compatibility
              by 2wtn
              Hi all, have been lurking here for quite some time, and now my first post

              People who have experience replacing CD3217B12 chips (on macbooks), I have a few questions for you.

              As far as I understand, the CD3217B12 exists in more than one type and the different types are not cross-compatible. Is that correct? How many types are there in fact that you know of and which motherboards is each type compatible with? Do they look visually the same, or is there some difference in marking?

              What should I look at when buying these chips online, for example on...

              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.

              Compatibility of main boards between different variations of samsung MU6100
              by JSin21
              Hoping someone here could possibly help. I have a few questions in regards to compatibility with main boards. But I'll give a quick short run down on what's going on first;

              I have Samsung Smart TV UA65MU6100WXXY version DA01

              Now years ago it started intermittently playing up after a lighting strike. Lighting hit the block of units i was living in at the time. Ever since that night the TV started having a mind of its own, It would randomly turn itself off or on, and all inputs stopped responding like HDMI, aerial, but USB still worked. Anyway, over the next few months...
