I've lost count of the number of times I've sat down in a BA 777 Club seat to find the IFE is inop.
Last time the FA apologised, saying that usually they would reset the seat, but they weren't too keen on doing it these days due to SR111.
It seems the system BA (and UA?) use on the 777 (GEC Marconi) is crap - apparently the Matsu!!!!a system (EK 777 and standard on A330) is much better.
