So my Cube died a week or so ago; after a power outage, it would not restart. I suspected the PS, as I could not get it to run a 4" computer fan when I touched the leads to the contacts on the PS-to-Cube plug.
I arrived back from a short holiday today and decided to do a little searching re. the Cube, whereupon I came across some advice to warm one of the corners of the power supply up with a hairdryer. At first sight, that sounded a little like "healing through crystals," what I call "Californian" Celtic Christianity, and similar voodoo, but there was a sizable thread about it on CubeOwner.com, so what the heck, I thought I'd give it a try.
Well, believe it or not, it worked. Not having a functional hairdryer, I used one of those little cube-like space heaters with a fan, which seems a more appropriate solution anyway. After about two minutes of gentle warming, the Cube sprang to life.
Apparently there is a known failure of a cold solder joint (from a capacitor) in the thing, so the theory is that even a little heat is enough to restore contact.
As I sit here, it is still working, though the PS has cooled.
I will obviously want to take the PS apart and fix it properly, but this has to be one of the oddest tidbits yet for me. Isn't the web wonderful (sometimes)?

Very cool (no pun intended)... 🙂
