HP 6735B BLINK CAP LOCK 5 TIMES, NO OTHER ACTIVITY- SOLVED

SORRY I WILL NO BE ABLE TO ADD PICTURES HERE BECAUSE AM VERY BUSY THIS PERIOD BUT IT WILL BE AVAILABLE ANYTIME AM DISPOSED.
I READ A LOT OF SOLUTION ON GOOGLE ON USING OVEN TO SOLVE IT BUT I HAVE TRYED IT SEVERAL AND DISCOVERED THAT YOU HAVE ONLY 10% CHANCE OF SUCCESS.
ACTUALLY THIS PROBLEM IS RELATED TO 1.MISSING COMPONENT DUE TO HEAT WHICH CAN BE FOUND BY CAREFUL INSPECTION OF THE MOTHERBOARD. 2. FROM THE AMD NORTH AND SOUTH BRIDGE. 3. FROM SHORTED MOSFET BUT THIS ONE IS NOT COMMON.
NO 2 IS MOST COMMON AND THE BEST WAY TO SOLVE IT WITHOUT REPLACING THE CHIP IS TO USE BGA REWORK STATION. SET THE PRE-HEATER  AT 270C AND PLACE THE MOTHERBOARD FOR 2 MINUTES, THEN SWITCH ON INFRARED FOR 90 SECONDS AND ALLOW IT TO COOL.THAT'S ALL.REMEMBER TO CLEAN THE FAN CLOGS

    bga rework station has preheater and uses infra red heater unlike smd rework station. the pre heating is very important in this process.
    thanks
