Yes, 3V3_S5 is missing. Measured on pin 1 R4212. I do have G2_EN (pn 13), but only .722V on 3V3_S5 ENTRIP (pn 6). So I wont get 3v3_S5.

3.158V on SMC_PM_G2_EN. I know, I had 3v3_S5 at the time of first post. Thanks.

25K with polarity reversed (black on ground, red on pin) Thanks Duke.

I'd like to revisit this post... I am afraid I misinterpreted the issue i am having therefore I did not post correct info... Here is a video of what it is doing. Basicly, it will not turn on from battery unless I unplug it from board and hold down power button to drain power left in board. Once...

Hey Duke. I have 3.124 K Ohm on PP3V42 Thanks

Shorting pin 5 on J5713. I have .007V on PM_SLP_S3_L & .003V on PM_SLP_S4_L measured on pin 4 of U9480 and pin 1 of R4690. Thank you.

Than you Sir.

Hi. Can someone tell me which adapter I need for 820-3536 ROM chip to work with tl866cs. Thanks.

It is. Thank you.

Got it. Thanks Duke. I assume your off... Enjoy!

Hey Duke. .643 MOhms on ACOK. Resistor looked fine. Swapped just in case. Still very faint green light... ACOK - 2.8 - 3.2V. Getting 3.3 - 3.4 on pin 5 U7000. Still very faint green. Guess Im doing SMC on this... Update - Replaced SMC. Same issue... Not SMC! lol.

Hi! Minor liquid damage around u3220, U3320 TBT area. DCIN fluctuates slightly and ACOK is low so I have a verrrry dim green light. DCIN - 16.5V - 16.8V PPBUS - 12.58V PP3V42 - 3.42V ISL 17/18 - 3.4 Ohm 27/28 - 20.9 Ohm ACIN - 3.8V - 3.9V (fluctuates) ACOK - 2.5V - 2.6V (fluctuates) ACOK in...

No networks... Checked around area you suggested and noticed that L1295 didnt look great so I changed it and things are now working. Thanks Duke... Appreciate it.

Both USB not working. They power on but nothing recognised.

Yea... Looks like I sent you the wrong pic. Thanks Duke. Im more concerned with the no power on/no green light with battery only for now. I reballed SMC to possibly fix the isdue. I dont have a donor with an SMC on it to use at the moment so...

This came in with liquid and corrosion around C7090-C7092 and F7005... Very quick easy power issue. Board powers and chimes but only shows flashing folder. I have tried booting to USB. It will power USB but not read it. With OPTION held down with USB and SSD I get only the network option, no...

Update So I guess this pretty much happens when ever power goes down beyond a certain point while on battery. If I let it go to sleep or shut the machine down while on battery, I cant turn it back on or do I get a green light unless I disconnect the battery, drain power and reconnect the...

Hi. I have 15" Retina with 820-3787 board that functions normally (green/orange light, boots, charges, etc..) Last night while it was fully functional I closed the lid on it to put it to sleep. This morning I came in and there is no green/orange light on charger and wouldn't turn on. The only...
