Narrative:

On departure from rno, retracted flaps from 1-0 and had 'leading edge extended' amber light in forward panel with 1 green leading edge light illuminated on the overhead panel. Kept speed at 220 KTS, and did checklist. Flaps did not move with handle position as we climbed. Checked WX and elected to divert to sjc based on WX and runway length. In descent extended flaps to 10 degree per book. No change to leading edge flaps (ie, trailing edge flaps indicated 10 and leading edge flaps indicated up with 1 indicating green). Planned 15 degree trailing edge flap landing at sjc, and cabin advisory was issued. While on downwind sjc, the leading edge flaps came out on their own to full extend. At no time was control an issue. With normal flaps now, went to sfo for a normal landing using 30 flaps.
