    Hello.

    I am writing a new topic because the ones that are already on the electrode did not wake up the album.
    The intel board
    No reaction on the ON button, nothing shines nothing works.


    PL4301 gland is approx

    PU4301:
    S - 19.6 V
    S - 19.6 V
    S - 19.6 V
    G - 3.2 V
    D - 19.6V
    D - 19.6V
    D - 19.6V
    D - 19.6V

    PU4502:
    S - 19.6 V
    S - 19.6 V
    S - 19.6 V
    G - 1.7 V
    D - 19.6 V
    D - 19.6 V
    D - 19.6 V
    D - 19.6 V

    PU4601 - it does not get power.

    Enter the motherboard symbol. Do you have ALW5 and ALW3 voltages after connecting the power supply?

    ALW - ??? I can not locate on PCB. Please brighter ...


    Is it about U4201 and U4202?

    I do not have PL4602 and PL4601 on the record .... it's about converters?
    I have a PU4601 which gives 19.6 V and PU4602 which does not indicate anything on the meter ...

    These are the main converter coils.
    Upload disc images in higher resolution on both sides.

    Sorry but the quality of the photos does not allow you to identify components.
    Remove the coil images of the coils around the inverter coils.

    We're flying from the beginning.
    How did the fault occur?
    Are you 100% reliable in the power supply?
    Does the battery behave the same way?

    After finishing work and switching off, the laptop has not started again.
    On the battery exactly the same symptoms. The battery currently has 11.72v

    power supply:
    Mass
    19,6v
    ID pin middle 0V

    I also checked on the HP power supply without changes ...

    Measure the resistance between each coil and ground with an ohmmeter. Search for short circuits.
    Apply the voltage from leg 16 to PU4603.

    Do you use the diagram when looking for a problem?

    The HP power supply is not suitable for this board, it can cause damage.
    CMOS reset made?
    Connect the board with the battery and give the measurement results from PU4503, pin 16,17,8, PU4603, pin 8, bones, bios.

    In the annex you have SM for this platform.

    Reset CMOS - done
    Bios pin 8 on the bat has 0.09
    power supply + bat has 3.31

    PU4503 on the bat has

    D-11.74v

    PU4603 can not locate on PCB where is it?
    pin 16,17,8 I do not understand.

    I have clearly written out the outputs with such numbers of the PU4603 inverter controller.
    The layout looks like on a photo.

    I'm already looking for PU4603 ... I was not there for a moment ... I have found on pcb ...

    PU4603

    On the power supply:

    pin 17 - 4.97v
    pin 16 - 19.58v
    pin 8 - 3.31v

    On Battery:

    pin 17 - 4.97v
    pin 16 - 12,122v
    pin 8 - 3.44v

    I will add that this element heats up very well after a few seconds. He's in his fingers!
    I guess it should not be so ...

    It's about the tension on this system
    pin.8 LDO or nap.3.3V (it powers min KBC)
    pin.16 and the rest as was written in previous posts

      Dell 5030 - dell inspiron m5030 - does not respond to ON

    If you do not have voltage on pin.8, then it's fault> charger or NCB (not counting "compact" ceramic capacitors, R in TPS51xxx environment
    Then measure to mass: VREG5 (17pin) and VREG3 (8pin)

    You need to determine the cause of the system's heating.
    Resistance from pin 8 of the controller and coils PL4602 and PL4601.
    Do you have a service power supply?

    I do not have a service power supply yet, but I was thinking about buying it yesterday. Can you recommend something ??? Made in China enough or something else some model?

    I drove to the furnace and I probably damaged the PU4603. As I checked again the voltage on it, my paws twitched and I closed the terminal pin 17 with pin 16 :(
    And now I have on pin 17 - 0.21v the rest of the tide is unchanged.
    I'm looking for lumber or I do not have somewhere 51125 And because he's sitting there.

    I found on another record as 51125 but without "A"
    Can I boldly solder it?
    Or does the letter "A" have any meaning?


    The system replaced by an efficient 51125.

    Pin 17- 4.93v
    Pin 16 - 19.57v
    Pin 8 - 3,27v

    The system does not heat up, but the board does not start ...

    You can exchange.
    Look at
    Link_ TPS51125A
    Link_ TPS51125
      (' :!: ')
    The difference (in the value of electrolytic capacitors on the pin ...) is described on the 1st page. datasheet TPS51125A
    As you have on pins ... ok.

    This should appear nap. output for controlling and opening keys (both channels should work)

    Meter set to 200K oops

    PL4601 - 10.5
    PL4602 - 01.5

    Meter set to 2M

    PIN8 - 591

    There are no tensions ....

    I have now checked the short circuit to the mass of the coils.

    I have a short on:

    PL4901
    PL4702
    PL4701


    So damage to the inverter or powered system like that?
    I am asking for a hint because I already have a confusion in my head and I'm not too good at repairing power failures ... that's why I am asking for help in order to improve my skills ...
