    dell e6530 error cpu failure.

    orignally posted in wrong section.



    When i turn this laptop on power led lights up,fan turns slowly,dvd drive lights
    up after that laptop turns off. After that it turns on again on its on and repeats
    same steps.There is blank screen,does not get to dell logo,F2-F12 does not work. After repeating few times three led lights up indicating error code cpu
    failure.

    I have swapped working cpu with same result.
    I have put in new ram with same result.
    When i start laptop with key "d" pressed the screen goes thro all diferent colors
    then switches off.
    I have removed rtc battery overnight and put it back in the morning, turn laptop on and it goes thro all above steps but this time there are NO error led
    for cpu failure showing any more. The laptop charges battery ok.
    The laptop has i7 quadcore with NVIDIA gpu.
    Motherboard is Qala1 LA-7762P.

    Is it power issue, gpu faulty or bios issue?


    Can anybody help me sort this problem please.

    Schematic available for this model. You need to measure power rails first. No harm in flashing bios but do make backup of original bios.

        You have to check CPU CORE, GFX CORE , DDR REF , DDR VTT check all inductor coils
