- Bad battery... I measured 0 V both methods. (making a short and directly on the J7050.) - On the Battery pcb circuit (under the sticker) i measured 12V. it seems that the battery circuit is not ok. I will order a new battery today. Can a problem on logic board cause a battery failure?

- My initial problem was a short on the P3V42_G3H. - I injected 2.V 500mA on P3V42_G3H and the short gone (very quickly). - I worked normally with the computer and the battery was charging normally. - After Some days the short on P3V42_G3H returned. - I injected 2V 500mA on the P3V42_G3H...

R7050 is ok with 10k. It is connected to the battery socket Sys_detect and GND. In PPVBAT_G3H_CONN i have 0V.

R7050 is good. I measured directly the battery ppVBAt_G3H_CONN with GND on battery cable (with the battery disconnected) and read 2.3V.

PPBUS_G3H ~ 1V 3V42 0

Do you know any good chaman? :) I already ordered the replacement parts and should receive it in the next few days. My question as related with some additional measurements in order to detect the culprit! Yes

I replaced the resistor and the board is already booting. Do you suggest replace the caps? Now i'm facing the original problem (battery 78% but not charging) is possible to check if the problem is from U7100 or Q7155 without replace the component? (i'm trying to find a scrap board)

C7090 in diode mode mesured 0.362V. I can't compare with a good board because i only have this board. I will try to replace R7020. Thanks

C7090-92- OK L7095 diode mode - 0.308 V

Today, after working normally with the computer (the battery charging problem is not solved yet as I'm waiting for the components) the computer stopped working (no green or orange light). I inspected the board and now i have found a new problem. The R7020 failed. Can it be related with the...

Do you know in europe where i can buy these components?

Again diode mode: SMBUS_SMC_5_G3_SDA -> 0.512V SMBUS_SMC_5_G3_SCL -> 0.513V With and Without Battery : 3.46V both

Hi, R7050 - 10k R7005 - 10 ohm SCL/SDA liines are SMBUS_SMC_5_G3_SDA? If yes, Measured at D7050: SMBUS_SMC_5_G3_SDA -> OL SMBUS_SMC_5_G3_SCL -> OL With the battery connected 0V on each. The battery is ok. (I tested in another mac)

Hi, I'm a newbie trying to repair my own laptop. The laptop stop working (no green or orange light) and i detected a short on P3V42_G3H due to a short on C5007. Its repaired and the problem gone. During the debugging process of the problem, accidentally (while trying to find the short) i...
