there were plenty of 8gb ram upgrades but that wasn't what i was looking for. i wanted 16gb ram upgrade. i only found one guy who did it on youtube which is why i asked the quesiton. Anyways, i think i ordered the correct ram (not sure becuase the video wasn't that high quality) and followed...

Is it possible to upgrade 00165/00164 to 16gb ram? I've been done 8gb but these days on newer os they are running pretty slow. I have a 4gb 00165that customer sold to me instead of fixing and wanted to upgrade to 16gb if possible. If it can which ram type do i need?

I don't have a good board to test on :( only donor board that a bunch of parts are taken off of. here are the diode values of j6100. pin 26 (mesa enable) is ground. i'm assuming this is a dead t2. have 2 questions. is it possible to be anything else besides t2? and second question is it...

was water damaged around audio ic/headphone jack. board was very clean no corrsion. was only getting 5v until i swapped out the cd3215 and now i have 20v .07amp draw. it is not turning on.

just for an update on this case. i ordered a donor board and dioded tested all the pads comparing to the working board. found a reading that was off and found a resistor that was not to spec. replaced it along both chips and now have speakers. moral of the story is test all the lines :)

is the same issue on this board. is there any way to test to make sure t2 is bad? should i take u6400 off and test the lines?

Just trying to understand here. if t2 was damaged wouldn't that stop the laptop from powering on? and second question. Since c6406 was short to ground (PPBUS_G3H_SPKRAMP_LEFT) wouldn't that have stopped power from going to t2?

Came in heavily corroded. I ultrasonic cleaned and reaplced both bad CD3217 and now computer is turning on. everything is working execpt there is no sound. sound is being detected in system prefs but sound is coming out of speakers. i found a couple of shorts around u6400 so i removed it and...

both are pulsing

pin 7 pules pin 3 pules as well

still 1/4 fan spin on smc bypass no pulse on PLT_RESET_L - 0v

got a 00165 which came in no with only green light. opened it up and it had screw was loose on MLB connected to L1290 which was melted. took the coil off tested both sides to make sure not short and replaced it. it now it has quarter fan spin. im assuming this is gonna be a dead pch but can...

U2800 was heating up after injecting 3V into the into Pin 5/6 on U8295 Replaced U2800 and everything is looking good. Thank you for the help.

Took a second look over the board & noticed u8295 getting hot. Removed the chip and Pin 5&6 were short (PP3v3_s0_left) Used an infrared camera and sent 1.8v through the line and it led to C2991(PP3v3_TBT_X_S0). Removed the Cap but short is still present.

These are the signals I could find test points for - P1V8SUS_PGOOD: 3.3V CPU_VCCST_PWRGD: .04V P5VS4_PGOOD: 3.2V S5_PWRGD is good

L8020: 1.8V L7330: 0V ALL_SYS_PWRGD: 0v

The USB gets power but no communication/activity. None of the big CPU coils get voltage on them L7900: 1.2v L8410: 3.3v L7960: 0.95v L8000: 1.0v PPBUS_G3H: 11.34 PP3v3_sus: 3.29 PP3v3_G3H: 3.3 PP5V_S0: 5.1

CPUCORE_BOOT1: 4.8V CPUCORE_BOOT2: 4.8v CPUCORE_BOOT3: 4.8v CPUCORE_BP1: 4.8v CPUCORE_PHASE1: 0v CPUCORE_PHASE2: 0v CPUCORE_ISNS1_N: 0v CPUCORE_SW1: 0v There is USB Activity I have not tried a known good bios yet

Client brought in a macbook - 820-00928 that wasn't turning on. It takes in 20V .1A- .8A fluctuating on all 4 ports Liquid damage on U3906 area No Voltage on Big coils Cleaned up corrosion Lifted U3906 removed corrosion. With a new known good battery it takes 2-3A - cpu doesnt get hot...
