Hi Alvar, I’ve visually inspected the board and the caps all look good. In fact the board, living as it has in a soekris case looks brand new. Apparently ‘no fan’ == ‘no dust’. So I’m going to rule failed cap. I think it’s more likely the BIOS/firmware is toast. It’s a shame really, as the board is otherwise perfect. :) Wouldn’t it be nice if one could short a pin and have it reload default/failsafe BIOS from a PROM. :) Failing that I suppose we’re in JTAG country. Does anyone know if soekris makes jig for that? —Andrew > On Dec 18, 2014, at 7:03 PM, Alvar Kusma <[email protected]> wrote: > > >> I then brought the unit over to my lab bench and hooked it up to my variable power supply. >> But then something magical happened at 5v, 3 of the network leds (the three that had been in use prior to the failure) lit up.

But without fan and on standard case? So, one reason can be just an dried up electrolytic capacitor. Something like those two large caps between coils, near USB connector. > > -- > =<Alvar>= _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
