I do get green to amber with the battery plugged in. Voltages with only battery, no charger: PPBUS_G3H 11.26v PP3V42_G3H 3.43v

Voltage with battery is fluctuating between 11.3 and 11.7v (tested with brand new battery). Resistance of pins 17/18 of U7100 is 3.3 ohms.

Hey all, have a 820-00850 board on my desk right now that came in with liquid damage, was stuck at 5v. Replaced a liquid damaged CD3215 and a few surrounding components and now board turns on and boots. When it gets to the OS the mouse is very laggy and the fans spike up to 100%. AHT reports no...

Did have correct voltage at R7110 pin 1, double checked the values of resistors. I went ahead and replaced U7100, got green light back. When booted board still does not charge though. Here are my U7100 voltages now: 1 - 0.004v 2- 17.90v 3 - 4.32v 9 - 0.293v 12 - 3.4v 13 - 3.4v 14 - 3.305v 15 -...

R7110/11 looked like they had some gunk around them, so I replaced both from a donor - same voltage as before. Removed C7111, voltage dropped to 0.006v.

Just to check my understanding (hopefully I'm learning lol) pin 3 receives its power from PPDCIN_G3H_ISOL which is what also powers U7090 through D7005. So that should be the same voltage as my power supply is outputting then, not next to nothing?

Apologies, forgot to paste my results 1 - 17.15v 2- 18.08v 3 - 0.762v 9 - 0.030 12 - 3.4v 13 - 3.4v 14 - 0v 15 - 0.046v 17 - 0.262v 19 - 5.502v 20 - 5.507v 25 - 5.190v 27 - 0.005v

Went to go take measurements and the first few were 0v and I noticed I lost my green light and PSU now pulls 0 amps. Did some checking and I seem to be missing SMC_BC_ACOK at U7001, but I still have PP3V42 going in. Is that a good sign U7100 is pooched?

Correct, both of those measurements were taken while the board is plugged in to power but turned off.

With battery DCIN_ISENSE is 1.05v and without it is 0.24v. Resistance between pins 27/28 of U7100 is 20.9 ohms

PPBUS_G3H with the battery is 12.5v when powered off, but it falls to 10.8v when I power on the machine. On charger without battery it's steady 12.5v. SMC_CHGR_BMON is 0.049v and DCIN_ISENSE is 1.05v

It's a genuine 85w charger. Machine runs without batt and light stays amber. Tried a brand new battery to rule that out too and the new battery wouldn't charge either.

I have an 820-00138 on the bench that isn't charging the battery, but runs fine from the battery. No liquid damage, was dropped on its side and hasn't charged since then. Tried a known working DC board but same result. I tested with an el cheapo charger and it does charge, just not with my bench...

Sorry, should have clarified. I have 0.108 between L7231 and PPBUS_G3H

At L7231 I get 0.108 in diode mode and the meter beeps. I take it that's not a good thing...

Looks like with both F7000/1 removed C7050 is at 12.27v

Looks like it isn't actually fully booting, I get no image when plugged into the display and I don't get any flashing on a USB drive plugged in. When it does hit 20v it pulls around 560mA

Hey all, had an 820-00840 come in liquid damaged. Cleaned some corrosion away from the area surrounding the CD3215's and after that the board was working fine for a day. The next morning, went to go turn it on and it booted half way then the screen went black. Took the board back out of the case...

No big coils have the same reading

I just measured again and double checked that I am in diode mode. I'm now getting 0.770 with the red probe as ground, and 0.910 with the black probve as ground.
