Narrative:
After normal power back, start and taxi to the departure end of runway 26R, we received takeoff clearance. Upon application of thrust we heard a takeoff warning alert. I returned the thrust to idle and the first officer advised the tower that we would taxi to the first exit taxiway (B10) and clear the runway. We did not exceed taxi speed. (25-30 KTS) upon closer examination we determined the flaps were in fact in the takeoff position (1) and the trim was properly set. Visual inspection revealed the leading edge devices were extended. We then noticed that since completing the taxi check the leading edge flaps extended and the leading edge devices overhead panel lights had become dark. There were no circuit breakers popped so we returned to the gate. Maintenance reset the leading edge flap position circuit breaker. After resetting all lights were operational. Suggest emphasizing confign check as late as possible prior to takeoff.

Title: FLC EXPERIENCES TKOF CONFIGN WARNING ON TKOF ROLL. THE FLC ABORTED, AND RETURNED TO THE GATE. MAINT FOUND A LEADING EDGE DEVICE CIRCUIT BREAKER POPPED.
Narrative: AFTER NORMAL PWR BACK, START AND TAXI TO THE DEP END OF RWY 26R, WE RECEIVED TKOF CLRNC. UPON APPLICATION OF THRUST WE HEARD A TKOF WARNING ALERT. I RETURNED THE THRUST TO IDLE AND THE FO ADVISED THE TWR THAT WE WOULD TAXI TO THE FIRST EXIT TXWY (B10) AND CLR THE RWY. WE DID NOT EXCEED TAXI SPD. (25-30 KTS) UPON CLOSER EXAMINATION WE DETERMINED THE FLAPS WERE IN FACT IN THE TKOF POS (1) AND THE TRIM WAS PROPERLY SET. VISUAL INSPECTION REVEALED THE LEADING EDGE DEVICES WERE EXTENDED. WE THEN NOTICED THAT SINCE COMPLETING THE TAXI CHK THE LEADING EDGE FLAPS EXTENDED AND THE LEADING EDGE DEVICES OVERHEAD PANEL LIGHTS HAD BECOME DARK. THERE WERE NO CIRCUIT BREAKERS POPPED SO WE RETURNED TO THE GATE. MAINT RESET THE LEADING EDGE FLAP POS CIRCUIT BREAKER. AFTER RESETTING ALL LIGHTS WERE OPERATIONAL. SUGGEST EMPHASIZING CONFIGN CHK AS LATE AS POSSIBLE PRIOR TO TKOF.
