My Front Blue Led shuts off, powers down and do all sorts of weird stuff. Does this indicated that the led will die soon, that not enough power is gathered?
Yeah, if you can get to the front part where it is, just check the connection.
If it does stop working though (though L.E.D's last a long time... I've never heard of one actually running out) then it should be easy to replace, and you could also change the colour if you wanted
Though I do actually prefer a blue L.E.D as the power light, than lets say a green one.
