    Sony vaio , MBX-224 m960 destroyed by another store !!

    Hey guys , received a sony vaio that came frmo another store , the client mentioned to me , that the problem with the machine was random shutdown ( since its a recent board with HM nb/sb chip , usually this cause of random shutdown is due to this bga ) but in the outher store , i think they lift 1/5 of the components on board , and it left the store without even turning on .

    I've cheked that 19 volts line was damaged , and really not passing to many spots on board , so fixed the 19 volts line , and now got 19 volts everywere like it should .Cheked also having 3.3 and 5 volts , and it turned on , but turning off after few seconds without displaying any kind of image at all ..but not turning on anymore , even that pwrbton drop to 0 when pressed . (alltough pwrbton on the nuvoton is at 1.60 and nothing happen.

    Cheked SN0608098R and seems fine for exception to pin 14 EN_1 should be 5 volts but have there 3.2 , just the same value as EN_2 (+3v)
    i will add values for pinnout more in the bottom of this post .

    So i reflashed the EC with a good dump for this exact board model , and it started to turn on , but there was no voltage to the cpuvcore coils .. 0 volts there , but meanwhile i had 1.5 for ddr and 0.98 for gpu coil and gpu was getting hot . then nothing else.
    So after does try really didnt made anything to it , but stoped working (not turning on even that all voltages are present on s3 .
    so returned to the previous original dump from this board to see any changes but no changes as well ..

    so start cheking nuvoton , and usually s3 pins are giving correct voltages , alltough i even have the bloody VDD at pin 4 . so something is not allowig the board to not turn on . after a very carefully chek , at CN30 ii noticed there was a bit of solder merging pin 6 to pin 7 (MB_FLASH_EN - CARD_INSERT)( EXTERNAL SPI ROM INTERFACE (EC)) .
    so lets for gor for some voltages

    SN0608098R pinout :
    1 - 1.97v
    2 - 0
    3 - 5
    4 - 3.28
    5 - 3.28
    6 - 19.82
    7 - 5.02
    8 - 0
    9 - 5
    10 - 5
    11 - 0
    12 - 0.88
    13 - 3.32
    14 - 3.20
    15 - 5.02
    16 - 5.02
    17 - 10.06
    18 - 0
    19 - 0
    20 - 5
    21 - 2.26
    22 - 0
    23 - 0
    24 - 8.34
    25 - 3.30
    26 - 3.30
    27 - 3.21
    28 - 0.86
    29 - 0
    30 - 3.30
    31 - 0.79
    32 - 5

    NUVOTON 783

    RSMRST 3.32 nothing happen in this moment when pressed on off btn
    VDD VCC and AVCC all with 3.32 v
    ACIN_EC 3.32v
    ALW_PWRGD 3.32v
    PWRBTN# 1.62v
    ALW_ON - 3.31v
    INST_ON_SW# 0.88v
    ECRST# 3.28v

    any outher measures need , just request.
    schematic is on the attachement

    also another thing i noticed , somethimes voltage on coil 3.3 and 5 , simply stay at 0 (for no aparent reason , without touching it , but pressing the on off button , they come back to good values 3.3 and 5 !

    Im tired of this board and would be good a help here.

    cheers guys

        yes this value is provided by HM55 ... this chipset are really a shame by intel .. so poor quality , major part of the latest machines i got here usually afyer hm replace they are ok . incredible !! they are passing AMD and nvidia very fast with they S#$% chipset.
