Narrative:

Assigned LAXX3 departure out of lax. We were planning (preflight) to use runway 25R for takeoff as that is what we usually get. After pushback, lax ground control told us to change to the loop departure and taxi to runway 24L. We reprogrammed the flight management computer for the loop departure off of runway 24L and planned an LNAV mode input after liftoff. Just before taxiing onto the runway for takeoff, the FMC computer dumped the departure out. I planned to take off and initially use headings and the lax VOR to start the departure, then reprogram the computer out of 10000 ft. After takeoff and after crossing the smo VOR 160 degree radial, we were supposed to continue on a 250 degree heading. I had the LAXX2 departure, runway 25L, still in my mind (apparently) and I turned left to 220 degrees shortly after crossing the smo 160 degree radial, which I pre-briefed at the gate before pushback. Lax departure control told me to turn back to a 250 degree heading.

Title: MLG CREW HAD A TRACK DEV DEPARTING LAX WHEN THEY FLEW THE WRONG SID.

Narrative: ASSIGNED LAXX3 DEP OUT OF LAX. WE WERE PLANNING (PREFLT) TO USE RWY 25R FOR TKOF AS THAT IS WHAT WE USUALLY GET. AFTER PUSHBACK, LAX GND CTL TOLD US TO CHANGE TO THE LOOP DEP AND TAXI TO RWY 24L. WE REPROGRAMMED THE FLT MGMNT COMPUTER FOR THE LOOP DEP OFF OF RWY 24L AND PLANNED AN LNAV MODE INPUT AFTER LIFTOFF. JUST BEFORE TAXIING ONTO THE RWY FOR TKOF, THE FMC COMPUTER DUMPED THE DEP OUT. I PLANNED TO TAKE OFF AND INITIALLY USE HEADINGS AND THE LAX VOR TO START THE DEP, THEN REPROGRAM THE COMPUTER OUT OF 10000 FT. AFTER TKOF AND AFTER XING THE SMO VOR 160 DEG RADIAL, WE WERE SUPPOSED TO CONTINUE ON A 250 DEG HDG. I HAD THE LAXX2 DEP, RWY 25L, STILL IN MY MIND (APPARENTLY) AND I TURNED L TO 220 DEGS SHORTLY AFTER XING THE SMO 160 DEG RADIAL, WHICH I PRE-BRIEFED AT THE GATE BEFORE PUSHBACK. LAX DEP CTL TOLD ME TO TURN BACK TO A 250 DEG HDG.
