Old Dell Precision 380 Workstation -- SOLVED

I know this is a long shot, but you RV buddies have help me out in the pass. I have an very old Dell Precision 380 Workstation -- must be 10 years old. I have not used it for about a year. It worked very well when I stopped using it. The other day, I agreed to give it to my Grandson.

When I went to check it out and clean it up, it would not turn on. No power to the "green on" button. When I removed the outside case the green light on the motherboard was on so I know the motherboard is getting power.

I blew the dust out and after a number of tries got the PC to turn on, but no internet connection (I know the CAT5 cable is good because it is the same one I am using now). After about a hour, the PC "died" without any notice. I have been trying for 2 days to get it to turn on

I replaced the round BIOS battery. No luck.

I have reconnected the wires from the power supply to the motherboard and the start button. Still not power.

I know there could be 100's of things wrong, but any suggestions are welcome before I "trash" it.

  • Both bad capacitors and bad power supply are the leading causes. If the capacitors look good then search eBay for a replacement power supply. Go by the part number on the power supply not the computer model.
  • The symptoms match the possibility that the motherboard is bad. The capacitors on the board are probably bad. If you look on the board you will find round devices that are usually wrapped in plastic and the top is exposed silver looking. If they show the top as expanded or cracked and/or the plastic cover shrunk that will be it. Unfortunately not worth replacing on a unit that old.
