J6100. LOOKS GREAT. After ultrasonic cleaning fan spnning 1 second and off. Not starts in SMC bypass mode. No continuity between SPI_MLB_IO1_MISO ( pin 2 of 6100) and R6114. No continuity between R6128 and R6123.I DONT KNOW NEED TO CHECK all SPI Bus Series Termination resistors and their traces?

Change u7000 again no luck. dont have right donor board. so will do it latter.

diode mode on SCL/SDA lines.= .479 and .464

SDA level directly on the battery connector and R5280 is ok and 0 v.

R5280 is good 2k and continuity to sda line is ok, Pin 10 at u7000 =0 v. it could be u7000 itself faulty or smc?

After removing c6952/53 got scl=.323 and sdl= .454, Changed isl625, scl=.454, sdl=.454 but voltage at sdl =0 , scl=3.42. it could be smc??

yes, it should be 3.4 V , do you know how to get idea how this charging do work?

AT u7000 R5280=2K R5281=2K , u7000??

After remove D6950 Voltage at SCL= 1v, SDA= .6v to 0 diode mode to ground at SCL=.342, SDA=.461

Yes , same with bill disconnected. Voltagae and SCL= 1v, SDA= .5v TO 0V diode mode to ground at SCL=.34, SDA=.463

BIL ??

820-2850 Battery not detected. Turn on with charger, green light , in osx shows no battery, but if i take out power adapter the laptop works fine with battery. This is know good battery, Battery indicator no light. Any help please.

Hi, This is 820-00165 orange light not turning on. Liquet damgeged around bios ( attached the picture) PPBUS_G3H 8.56 PPBUS_S5_HS_COMPUTING_ISNS 8.59 PPBUS_S5_HS_OTHER_ISNS 8.65 PP3V42_G3H 3.4 PPVRTC_G3H 3 PP5V_S5 5v PP3V3_S5 3.3 PP3V3_SUS 3.3 PP1V05_SUS= 1v Any help please.

Bios file location please?

I just replace the u6100 bcz my original chip was damaged.
