    820-01700 No power 20V 0.07A no battery. 20V 2.5A with battery

    Ok. It may sound stupid or I'm being stupid, but I was measuring short to ground in Ohms by setting my multimeter to OHMS and black probe to ground and red probe on the L9580 - P2V5_SW1_TPS62180_SSD0. Before it was showing 4.7ohms. Now it keeps increasing till reach 20.2K. In diode mode L9580...

    820-02020 - MacBook Pro M1 2020 - blown UC710 (SN621371)

    Hi everyone. This MacBook had liquid damage about 10 months ago. I've replaced a few components and done U.S cleaning and it is back to life. So, now it is back to me with no power: TrackPad clicking and a loud fan. After opening, I found a blown UC710 (SN621371) that I only found the...

    820-00163 - PM_SLP_SUS_L Cycling

    I've missed this PP5V_S0 shorted to ground. Basically all CPU phases mosfets, U7701, U7400 and a few more components that get PP5V_S0 is dead. Applying 1V on PP3V3_S5 Chipset U1100 gets hot. I guess this is beyond repair, as I don't have the right tools to replace the chipset. Thanks for your help.
