    dell e5440 turns on 3 seconds with fan at max

    this card is the same as that of the other discussion E5440 VAW30 LA-9832P, connecting power turns on the power led and fan at max for 3 sec then all off, as if you didn't see the ram, then if you turn it on again with the power button it doesn't turn on, I tried to disconnect the power supply and jumper pins 5 and 6 of U1 and U2 while I re-connected the power supply, and it turned on normally, then after turning it off when it was turned back on it didn't turn back on like at the beginning

    I solved the problem, making a check of the present voltages, measuring the + 1.35V-MEN-P this was not present, measuring on PQ100 the pins 5-6-7-8 there was no voltage, on PL101 the + PWR- SRC was present on point 1 but not on point 2 of the coil, measured in ohms it was ok but it did not make contact with the pad, the welds on the coil were re-made 1.35v_B + is adorned on pins 5-6-7-8 of PQ100 and so even the + 1.35V-MEN-P is back and the notebook has started working again.
    regards
