    Missing RSMRST# on hp JAL50-LA-4101P

    First problem of the laptop was when cahrger connected Charger led is not present..

    after checking all ive decided to flash the bios.
    Now the DC jack glows ,after checking the first reset signal the RSMRST# IS ov

    32,768KHZ is present at Y5 on oscilloscpoe
    RTCRST# has 3.3v @ CLRP2
    RSMRST# 0v @ pin 100 f ec
    ON/OFFBTN @ pin 32 has 3.3v when triggered goes 0v and goes 3.3v if released
    PWRBTN_OUT# @ 117 has 3.3v if triggered the switch doesnt goes to 0v .

    EC_ON @ 102 -3.3v


    Ill also attched my backup bin.

              820-02020 PPBUS_AON missing
              by ugamazing
              Board had no history of liquid; unsure of drop history, but no signs of damage of any kind worth noting.

              Charger sitting at 5v/0a. PPBUS is at 1.9v-0.9v steady cycle (peaks, drains, loops). Confirmed CHGR_EN_MVR is missing, but DCIN was reaching ISL just fine, so replaced ISL--no change at all. Confirmed pp3v8_aon is also missing--and being unsure *exactly* which signal appears first (or if they are simultaneous), I inspected PMU/U8100 area and found no shorts, but also found PP3V8_AON_MPMU_ISNS_VIN missing (not shorted). Replaced U8100 just in case (have had them fail in weird ways),...

              Apple NVIDIA AGP GeForce 6800 GT Dual Link DVI+DVI outputs 603-6338 missing caps!
              by jpreza
              Hi everyone,

              I recently acquired this card from a seller who was selling a PowerMac G5 for parts. He mentioned that the video card was probably broken too.

              Upon closer inspection, I can tell the reason why it won't work: it's missing a bunch of CAPS! (it's also missing an inductor - 1.0uH).

              It's a nice card as it's one of the few AGP cards that will support 2560 x 1600 resolution on a PowerMac G5 using a 30" Cinema Display.

              Looking at the card, it appears to be missing the following:

              1x 1.0uH inductor - orange square
              2x...

              Asus Zenbook UX431DA / UM431D - Ryzen - missing PWM Fan Signal.
              by gurj1979
              Hey guys.

              Need help with this one.
              Fan not spinning due to missing PWN Fan signal.
              Also 5 seconds from powering up it freezes, unless in BIOS.
              But as soon as Windows starts to load, it will freeze.
              CPU is COLD / Room temp when it freezes.

              I've replaced the CPU, same problem.
              Replaced SIO/KBC IT8987e and reprogrammed - same problem.
              Replaced fan - same problem.
              Replaced flex cable from board to daughterboard (which has fan connector on it) - same problem.
              Checked the Thermal sensors around CPU and Board to the SIO/KBC and...
