    Only VCC_GT is missing.

    Hi.My laptop is hp i3 7gen with LA-D707P MB. NO VCC_GT voltage is created .all other voltages are ok.VRN_ON#,PCH_PWON# are OK.mosfets are ok VCC_GT Core impedance is 6.OHMS.

    No signal to PU1101 of UG1_GT, LG1_GT see the picture. Will replacing PU1101 chip fix it..? Thanks in advance.

        Hi. My laptop has no display. My motherboard is HP LA-D707P. All voltages are ok .I checked the bios pins with a oscilloscope but see no clock signals .but see only 3.3V . I did flashed the bios 2 times.even used new chip.

        Now please educate me which direction I must go. ?

          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...

          Macbook Pro Retina 13” 820-3476-A (A1502) - missing PM_SLP_S4_L
          by salopian
          Hello. I would need some advice please.

          My son's MBP suddenly stopped working and is now only getting the green-then-orange light on Magsafe and no fan spin.
          He brought the MBP into the house (22 deg C) from a very cold conservatory (-3 deg C) and turned it on straight away. The Mac suddenly died a few minutes later.

          I examined the logic board and couldn't find any signs of water damage, corrosion, blown up components etc. Nothing was ever spilt on it, and the logic board looks immaculate.

          I have already replaced the logic board with another...

          Missing Capacitator Intel I9-12900KF CPU
          by ein_individuum
          I bought a use Intel I9-12900KF CPU and i received it damaged. But it looks like only one component one the backside is missing. But the solder pads looks fine.
          I already "googled" it and compare the backside picture of other LGA1700 12th Gen CPU. They look all the same, no matter if its an I9 or an I3, even the Pentium. And at that spot should be a capacitor.

          Does anyone have a schematics or assembly diagramm of the alder-lake cpu-backside? Or just know what size and value i need to replace the missing capacitator.
