Junior2's Alienware lapdog just let out some magic smoke accompanied by the usual acrid smell,
and got a terrible pain in all the LEDs down it's right side.
But it continues to compute correctly.
The smell is that of Electrolytic Capacitors that have let the smoke out, but it turned out not.
Strip-down and I find that an I/O PCB which has several USB ports and the LAN port, and a tiny connector for the 'Tron' decorative LED strips has failed.
Specifically, the 'Tron' LED connector and the cable coming from it has burned and melted.
The melted remains of the connector on the PCB still contains the connector part of the destroyed cable.
Faulty connector or cable, I'd guess.
I can source a new PCB, with a week's lead time, but the cable is more difficult.
I've just de-soldered the melted SMD connector from the board and cleaned the board up.
I'm hoping the board is otherwise undamaged, and can be pressed back into service in the meantime.
I can't leave the whole board out, as the main CPU fan connector is also on it.
Re-assembly tomorrow night and hopefully we can be back up, but without decorative LEDs.
