    Old PII PSU won't "jump start"? What am I missing

    I am trying to configure an old PII ATX unit as a test tool/watercooling pump bleed tool but I have hit a snag. When I try to "jump start" the PSU by connecting the green wire to ground, the PSU only fires up for a split second and then quits. I tried wiring a couple of fans to the 12v and 5v rails to provide a small load, but that didn't seem to help either. What am I missing? I have never had a problem jumpering newer models in this fashion.

    You may need more load than that on the PSU than a couple fans can give you. Try using a hard drive, that always did it for me.

      Launch Automotive Diagnostic Tool Missing Diode and Cap
      by Kyleadonis
      Hi there, I need some help identifying replacements for a Launch Diagnostic Plug In Tool. I can't seem to find any information on the LF 7HZPU Diode so I have no idea what to replace it with if anyone can help? Also there is a missing component on the side that I highlighted in green and I assuming it's a cap?

      I have added some photos for reference....

      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...
