Hi. No fan spin whatsoever. Present rails. PPBUS PP3V42 PP5VIN_S5_HS_Computing PPVIN_S5_HS_GPU PPVIN_S5_HS_Other PPDCIN PPRTC G3H PP5V_S5 PP3V3_S5 pm_slp_s4_l Diode mode .480V Liquid damage heavy around U9600, J2550 area, T29 Area and Codec Area. Replaced burnt corroded components around...

Yes. Replaced SMC today. All is good. Thanks, have a good one.

Ohhhh. I seeee. :o lol. Thanks Smiba for all your help and info very appreciative. Duke... Till next time.

Hi. G3H is steady at 12.56 V. R1800 - 3.242 V R1801 - 3.050 V R1802 - 3.337 V R1803 - 3.337 V Thanks. Duke. You mentioned GPU Vcore. Doesnt it need PP5V_S3 to function? Which I am missing. Thanks.

Hey Duke. It very well could have been now that you mention it.. Thermal compound doesn't look original. Some discoloration. But board is clean and edge bonding still on. Doesn't mean someone didn't hit it with a paint stripper I guess. I will look closer tomorrow. Thanks.

OK. Will check this out in the morning. I have frequently measured G3H and Im pretty sure its around 12.56 V with the fan off. But will do like you said and double check and check those resistors. What about PM _SLP_S4_L? Shouldnt that still be present while in an S5 state? Thanks a lot man...

Diode mode PP3V3_S5 - 130V. Replaced U7201 and I now have PP3V3_S5 at 3.3 V. Fan spins once around and stops. Unfortunately still do not have PM_SLP_S4_L. PM_PCH_PWROK - 0.001V. U2800 Pin 16 - 0 V Pin 15 - 0 V Pin 14 - 0 V Pin 13 - 3.4 V Pin 12 - .386 V Pin 11 - 0 V Pin 10 - 0 V Pin 9 - 0 V...

Ok. Thanks again.

Thank you. Im sure you are busy. I appreciate you taking the time to reply and your explanation is helpful. I will check tomorrow. You have a great night/day. :)

Isnt PP3V3_S5 created at U7201? Same as PP5V_S3? If Im missing PM_SLP_S4 then how can this be fixed. Or will the chip create PP3V3_S5 seperatly? Which in turn could supply U9550 which then could help with my PM_SLP issue? Im not at work right now, but I remeber checking P3V3S5_EN high and I...

Smiba- Termination resistors (if Im in the right spot) are 47 .Ohm Hey Duke. Not sure on the history of computer to be honest. Board looks very clean in the way of liquid damage. Only minor discoloration to the right of U6100 (if the SMC was on your right side) No other obvious damage jumps...

Pin that keeps frying is 17 on U7100, VCCSAS0_DRVH. Thats output. What can this be? Burned hole through Q7100. ??? Thanks.

Thanks man. Really appreciate the response and the explanation. That helps. Pin 10 is 0.6 Ohms and pin 16 is between 0.5 and 0.6 Ohm. I have replaced U7100. Just haven't put power to the board yet. Kind of hesitant to. I keep frying Q7030, Q7035 & ISL. Running out of parts, so I want to be sure...

Thank you Smiba. appreciate it. Kind of unsure where to locate but will figure it out. Thanks again.

Hi. No liquid damage. Looks like SMC was replaced. Original the fan would spin once for 3 seconds but not recently. All power rails are present up to PP5V_S3. Diode mode 0.412. Have 12.6V on 23 of U7201. SMC_PM_G2_EN is 3.4.V. Missing PM_SLP_S4_L. Diode on this line is .480. Thanks for your help.

Update. Starting over. Came in this morning and replaced Q7030 & Q7035, ISL and U7100. In diode mode G3H is .428, PP3V42 is .332. U7100 has some lines that are beeping to ground. These are pins 10, 13, 16, 4 & 3. Im Fucked right?

No battery, only charger. plugged in on last attempt. I had PPBUS which seemed a little low in diode mode (.386) and PP3V42 both which I didnt have to begin with. Green light wassolid then started pulsing. All of a sudden U7100 , C7553 & C7561 boiled. Im not sure yet about ISL, I had to leave. I...

Hey man, how are ya? Thanks. LOL... OK. Lesson learned. With charger only I had PPBUS G3H, PP3v42, pp3v3. I was about to check pp5v_so and U7100 started to boil, as well as C7553 and C7561. U7000 also got very hot and I think its blown again. VIAs around u7000 are pretty discolored now. PPBUS is...

Hi. When I started this board I had PP3v42 but with no green light and no PPBUS. PP3v42 was 3.42V and PPBUS was shorted to ground.ISL was getting hot so I removed it and replaced ISL. I checked PPBUS in diode and most of the short was almost gone (0.386) but still no PPBUS. I plugged in the...

Hi. Thanks for your response. PP3V42 is now holding steady. Still 1 fan spin. 0.128V on pin 1 C4920. 3.47V on pin 2 of L4901 and pn1 of C4901. PP3V42 in diode 0.088 with L4901 in place. if I remove L4901 I get 0.338. Thanks
