Re: Dell 3008wfp faulty power supply
8 months eh? That IS a new record. Just kidding.
OK. First of all, don't worry about replacing the D22 schottky diode for 4 reasons.
1. The newer PSU's have a better diode. 2. We remember what happened last time you got into that. 3. You can always use a surge protector. And 4. "If it ain't broke, don't fix it" my Grandpa used to say.
After your friend replaces that capacitor. With the PSU all by itself, and not connected to the main board or the inverter. You'll need to turn over the PSU. Plug it in. And you'll only get one voltage output. The 5 volt standby. I marked the ground and the positive connector pin in the lower left of the picture. That should be 5 volts or above. And steady. No fluctuations. Mine showed 5.2 volts and steady.
All the other voltages will power up later when the main board is connected and sends back the PS_ON (power supply on). But we don't need to worry about that right now.
Just look for that 5V standby voltage on the pin marked in the picture.
