SCL = 3.40V SDA = 3.40V PPBUS_G3H W= 10.80V PPBUS_G3H W/O = 19.54V EFI ASD = tomorrow (I'm downloading the files). R7151 = 2.8 ohms R7152 = 0.8 ohms SMC_CHGR_BMON_ISENSE = 45k / 0V

Hi! There was spill in the U7100 and U7501 area, so I replaced the two ICs and some components around them. Now the macbook can start and work (fans spin very fast), but it does not charge and puts "repair" in the battery state. The charger led blinks green twice, stays steady for 1 second and...

Good afternoon mates. The board is already manipulated (traces of flux) and there're no traces of liquid: - PPBUS_G3H: 12.53 V - PPBUS_HS_CPU: 12.53 V - PPBUS_HS_GPU: 12.53 V - PP3V3_G3H: 3.0 V - PP5V_S5: 4.99 - PP3V3_S5: 3.3 V - PP3V3_SUS: 0V - PP1V8_SUS: 0V - PPVCC_S0_CPU: 0V - PPVCC_S0_CPU...

Hello everybody. The macbook had liquid damage around U7000, it was changed for a donor but, there are problems in power on. When I try to turn it on, it marks me as having no battery and after 15-20 minutes of letting it charge, it turns on with + 50% battery. The failure is random since...

Finally, I have been able to solve it thanks to 2informaticos. There was no communication between R7151 and R7150: I jumper and it starts, but the fan turns at maximum; I run an ASD and it tells me there's a problem with the fan but nothing else. SMC replacement (had replaced 3 before) and...

I did what you told me but I couldn't see anything abnormal. Add that when I connect the charger, PM_SLP_S4 / S3 / S0_ L, they give me 3.3V until the fan stops (1-2") and they drop to 0V.

Good afternoon. I got an 820-3476 that did not turn on: ppbus gave 0.60V. I reballing SMC and it turned on but it had a graphics error: the system detects 15mb on the graphics card and 42 "on the screen. I have tried 3 SMC's from donor boards and none works: it only gets started with smc...

Yes sir, both options but give error.

Yes sir. I try to update it, the progress bar advances 5-10%, quickly reaches the end and after several minutes, it throws error 4005.

Good afternoon, guys. The MacBook had gotten wet, the damaged components have already been replaced (including CD3217), it manages to go up to 20V - 1.30A but it resets to 0A. Reviewing the Power sequencing diagram, the voltages reach the part of H9M LOAD SECURE ROM, SMC BATTERY TRAP: the last...

PLT_RESET_L pulses twice and stays 0. Bad CPU? SPI Bus Termination resistors and traces.( will check this but i think it's waste of time)

Got this board. All s5 rails are present. No water damage. Just stopped working. ALL_SYS_PWRG is 0V. When i connect magsafe fan doesnt spin but board pulses all s0 rails for a second than stays in s5 state. In SMC bypass fan spin and stop twice and than nothing happens. The only rail not...

thanks. will try or revive donor board or swap CPU from it. Will post when done

does it have firmware like smc, or just swap?

Thanks. Confirmed, it is bad cpu. have u ever changed one? Can i take from donor board with same cpu?

L7960 on pin 2 PPVCCIO_S0G is 1.2 ohm. With Q7960 and L7960 removed

Definitly i am not decided to fry CPU, this is why i am registered in this forum and asking question to you. Still not injected removed Q7960 and short is gone, after that removed L7960 and short was on second pad ( PPVCCIO_S0G). Dead CPU? Thanks in advance for your help

No water damage. Short on ppbus. Removed R6905 and checked that short is on pin 1, after that removed R5400 and the short is on PPBUS_G3H_CPU. Can i inject to check what is heating up?

Ok, thanks.

Could u explain me More please? Where i can get that tool?
