First LED when power button change to 0v and at 3.3V with S5010 pads for test
PP1V1_S5_REG - 1.1V
PP3V3_S5_REG - 3.3V
PP5V_S5_LDO - 5V
PP12V_S5 - 12.05V
R5010 is good
any ideas ? thanks
shit!!!, in a hurry I didn't read the second part of your email... obviously it's not a chip that's easy to solder, but I'm stupid.
remove F7000 I have short in PPBUS_G3H
I removed the u7000 ic but I still have a short on Q7030/40
I also have a short on the pads on the u7000 ic

I have done tests with the short in R6950 but its behavior has not changed
It stays on for a while sometimes for 5min voltage 8.05v when it turns off 8.15v
I have also noticed that when it fails despite having the battery connected it also turns on automatically when connecting the magsafe

Hello, I received this device, it does not turn on and there are no liquid damages. I bought the Q7040 and I have a short in the pins:
Q7040
1 PPVBAT_G3H_CHGR_REG
2 PPVBAT_G3H_CHGR_REG
3 PPVBAT_G3H_CHGR_REG
4 TBA_GATE_Q3
and Q7030 in:

Replacement or could the problem...
Hello, I received this device, it does not turn on and there are no liquid damages. I bought the F5200 and I have a short to ground with a value of 002
I have checked the coils and the mains and they seem to be fine
Any ideas? Thanks
ok now I have :
pins 17/18=04.9 (scale 200)
pins 27/28=20.6 (scale 200)
i have continuity pins 27/28
It turns on, battery connected but when I disconnect MagSafe it turns off. Battery charges and percentage appears
remove r7121/22 and solved
If I put in just one, everything is fine, but if I put in two, I have continuity again (resistance in good condition from other logic boards)
yes this is good 21,2 ohms But if I put it in diode mode I have continuity between its pins and I have checked with another board and that should not happen
I have already checked those resistors and they are fine, but I have checked the line and the C7120 has continuity. I have removed the component and I still have continuity between its pins 27/28, therefore I think that the U7100 is damaged. Do you think the same?
Yesterday after the repair it doesn't turn on, but I'm going to check these voltages and it turns on... I've been using it for a couple of hours and it seems to work
Thank you always for your enormous help
