    Acer Aspire 5100 (HCW51 LA-3121P motherboard)

    Hi

    Got an Acer Aspire 5100 laptop with Compal HCW51 LA-3121P motherboard.
    It stoped during operation.

    The 1.2V-psu died. (+1.2VP_HT)
    PQ27 FET got shorted, therefore the B+ rail protection kicked in.
    Removing PJP10 jumper, I measure 7.3 Ω to GND on the 1.2V_HT rail, is this
    acceptable? Would Give around 165mA.
    C75 and C24 are good.

    Someone who still has this motherboard, please help me by measuring the resistance on C24. (like I said, I got 7.3 Ω)

    Thank You.
