    [B]Lenovo Ideapad 100S-14IBR EEPROM VCC shorted to ground[/B]

    Lenovo Ideapad 100S-14IBR

    need help guys.. Bios ic UX3 - 25Q64FWSIG no 1.8 volts

    shorted 1.8ALW volts to ground. eeprom is ok


    Findings : i disconnect the vcc from the circuit using jumper 1505 and test the output of the 2Z-3F F0V ic it produces 1.8v so i injected a 1.8v in the vcc of the eeprom and somehow the processor is heating up and it draws 2.090 amps .

    my question is how much current does this ic can produce at normal level. does the 1.8vALW powered the processor.

    am i dealing with a shorted processor? need help guys.. thanks in advance.

      I'm sorry to tell.this, but yes the 1.8V is connected to the SoC and yes, it is a shorted SoC.

              Apple 820-3662 VCore shorted to ground.

              Hi, Would appreciate some help.
              I have an Apple Late 2013 15" A1398 MacBook Pro with Logic Board 820-3662.
              Get charger light but no fan spin or chime. No liquid damage.
              Found PPBUS and VCORE both shorted to ground. Other rails were ok.
              Removed VCORE MOSFETS U7310, U7320 and U7330. Found U7330 was in fact shorted.
              With the 3 MOSFETS removed, get PPBUS and fan spin. VCORE is still hard shorted to ground (0 ohms).
              Attempted voltage insertion on VCORE to locate short using bench supply set at 1.0 VDC and 4.95 Amps (max current for my...
