I have a SheevaPlug computer. I have been using it as a DHCP and DNS server in my home network. But recently, it just stopped working.
I unplugged it and plugged it back in, but it was completely dead. No LED activity, nothing.
I did some research and discovered that they are prone to power supply failures. That seemed to be my case. So I opened it up (the screws are hidden under the little rubber feet). I opened up the power supply box and discovered this:
It doesn't show up all that well in this picture, but almost ALL of the capacitors are burned. You can see the large one in the center has a raised and bubbled black area on it.
The power supply is just a 5V 3A supply. I looked through my power supplies I have that I'm not using and found a D-Link supply that was 5V and 2.5A. Good enough. I cut off the plug and wired it up. By the way, the positive output from the power supply goes to the red wires on the Sheeva. It even says +5V on the board. It may seem obvious, but I don't recommend hooking it up backwards.
After a little bit of solder and electrical tape, I plugged it in and voila:
It's not as pretty as it was, but I booted it up and logged in and everything seemed to be working.
I'm going to re-configure it as a web server since I don't really need it to be a DHCP or DNS server. It was more of an experiment and learning process for myself.
