Precision 670 VRM 0? Power up failure...

  • My Precision 670 refuses to boot and the post lights seem to indicate a VRM 0 failure. The machine fans are running full tilt on power up.

    Can someone please point me to the location of this circuit on the board as I am happy to brandish the soldering iron on any duff parts. I have already noticed a couple of suspect looking 2200uF 63V capacitors in the region of the 2nd processor location, but only have 1 processor!

  • Yes, thanks, that's where I found the diagnostic. Unfortunately that doesn't help with repairing the problem...

  • OK, I replaced numerous capacitors that had become 'bloated', but to no avail ! Still same fault lights. Anyone from Dell oblige me with any ideas please? I'm at the point of 're-cycling' the machine now, which seems such a tragedy.....

  • Darn! Now that's unlucky!

    I've emailed Tech Support to see if they can provide more technical details for a fix, but I'm not holding my breath...

    Thanks for taking the time - it's much appreciated. At least I was on the right track!

  • Hi ! I have the same problem with my Dell 670 workstation. No motor or function from drives. first light green and two yellows. not sure what i need vrm bay empty!!

    Thanks for the help!

    respectfully,

  • The vrm0-module is a fixed part of the mainboard, only the vrm1-module can be relaced separately. You can replace the board,

    but as many other users (including me) you are affected by Dell's decision to use low-end parts (condensators) on mainboards.

    This leads to premature defects of this boards. Replacement boards are also equipped with this parts and will not last for a long time.

    If you are a key-customer you can hope on fair-trading, if not (as me) you will not get any answer or help from Dell  :-(
