I have 3.16v at pin 2 of R1915 It measures 193k not the 390k it supposed to

PCH_DSWVRMEN_L= .489mv I’m not sure but the brd file say pin 1 of u6100 is PM_SLP_SUS_L =0v

Hi I have a board missing PM_SLP_S4_L Cpu prerequisites: ppvrtc_reset_L=3.3v Pch_srtcrst_L=3.32v Pch_intvrmen_L=3.24v Pch_dswvrmen_L=.489mv Sysclk_clk32k_rtcx1=.489mv PP3v3_s5=3.3v Pp3v3_sus=2.7v Pm_batlow_L=3.3v Pm_rsmrst_L= 3.4mv Pm_pwrbtn_L=3.45v I also have power u6100 on pins 8,5 but not...

Ok, that worked. thank you very much.

The weirdest thing just happened I made the cord put it to my power supply and it chimed :/ but all my test chargers won’t boot with it. I put my test MagSafe and it MagSafe green light goes out immediately It’s at 18.4v and drawing 1.13A I’m not sure what’s going on here these magesafe work...

Ok I’ll try another dc in board I’ve tried several. I have 2 original 85w chargers that I swap back and forth as my test chargers. But I will prepare a 85w cord with lab power supply and tell you how much current it’s drawing later on today Thank you

There was a droplet of corrosion I cleaned up by q7080 when I started also there’s some small corrosion by u7940, u7400 it’s like it hit all the best parts of the board :( honestly I was gonna change q7080 as soon as I received this board but since its so close to u5701and j5800. I was...

Yes F6905 is good same 1.7v at fuse R7080 =99.2k R7081 = 61.4k R7085 =468.3k R7086 =330k R7051, r7052= 3.2ohm R7021, r7022=20.5ohm

All good issue resolve a resistor and cap with broken trace by isl for u8900 gpu Thank you for your help

Pin 2 : L7530 - PPVCORE_SO_CPU_PH3_L=1.16v L7520 - PPVCORE_SO_CPU_PH3_L=1.17v L7510 - PPVCORE_SO_CPU_PH3_L=1.16v L7550 - PPVCORE_SO_CPU_AXG_L =0v ALL_SYS_PWRGD= 3.4 at 7974 R7974=0 ohm CPUIMVP_AXG_PGOOD=0v - .9v pulsing almost like a charging and discharging of a capacitor. I look at the...

PPBUS_G3H = 1.7v PPDCIN_G3H= 1.7v 3V42_G3H =0v 3V3_S5/SUS=0v R6929=0v SMC_BC_ACOK Also on this board I know that R7403 is reading “OL” R7402 is 180k so I know that R7402 is good. but I haven’t changed it till I resolve the issue that I suspect is on the 3.42V line. The mage safe flashes and...

Thank you for clearing that up :)

Hi I received a board with liquid damage in 2 areas 1st Area: u7400 in area CPUIMVP_TONB (R7403,C7441) AND CPUIMVP_ISNS1_P (R7406,R7466) the resistors #’s are just to pin point area of corrosion 2nd area: Q5300 and R5314 I get a green light and quickly the light goes out in a split second...

Hi, First I wanna apologize as I don’t know if this is the right place for this question. I have a few boards a1466 from ranging from 2013-2015 I’m looking to buy a test enclosure I found a few 2013 and A few 2015 Enclosures Both seem pretty similar. Are all these board compatible with either...

Hi I have a board that doesn’t chime. Audio circuit is fine. all my voltages are present and have fan spin. But, no mouse activity. The mouse blinks only once in start up. I checked for cpuvcore voltage it’s 12.5 and resistor R7402 is 90.7k I guess my question is that On pin 1 of R7402 what is...

I replaced u7000 and I have the same issue But I noticed the PPDCIN_G3H= 16.71-16.04v fluctuating again I’m thinking there must be a loose connection or bad solder Joint somewhere there also flux around the mage safe and fuse.

R7080=99.2k R7081=61.4K R7085=471k R7085=330k

ISL6259 1=15.05v 2=16.17v 3=4v 9=0v 12=3.41v 13=3.41v 14=3.2v 15=0v 17=7.62v 19=5.05v 20=5.07v 27=7.74v Q7085 CHGR_AGATE_DIV= 15v I believe the issue is with my voltage divider shouldn’t it be 6.5v

ISL6259 Pins 17,18= 3.4 ohm 27,28 = 20.2 ohm

3V42_G3H=3.42v PPBUS_G3H =11-7 but it doesn’t fluctuate it drains. I put probes on it. It goes to 11v then drians to 6-7v PPDCIN_G3H= 16.71-16.30v fluctuating
