I replaced the battery and it has fixed the issue. Thank you for the guidance... much appreciated!

I can try a good battery, just don't have one right now. The laptop is so slow it takes 30 minutes to login and for everything to load. Would a bad battery do that?

Hi. Macbook Air 2017 A1932 820-01521-A. No liquid damage. Powers on ok. Performance is sluggish and fans initially spin slow but get faster and louder after 2-3 minutes. Apple diagnostics reports: 1) battery requires service: PPT006 2) There may be an issue with SMC: PFM006 Does this SMC need...

Tried to heat up CPU as instructed. Did not help. Is it worth validating PCH is outputting correct frequencies? Thank you for the help and guidance. Much appreciated!

PM_SLP_SUS_L = 0v Also originates from U0500.

PM_BATLOW_L = 3.342v

RTC_RESET_L = 3.341v PCH_SRTC_RST_L = 3.341v (the doc refered to "SRTC_RST_L". I assumed it was this one) PCH_INTRUDER_L = 3.073v PCH_INTVRMEN = 3.249v

I do not have the original magsafe charger. PCH_SRTCRST_L = 3.342v PCH_INTVRMEN =3.25v PM_DSW_PWRGD =3.4v PCH_DSWVRMEN = 3.25v PP3V3_S5 = 3.34v

3V3_SUS = 0V checking that Rail

Macbook air 820-00165-A Charger showing green for 3-5 seconds, then orange light. Drawing 0.118A on power supply PPBUS_G3H = 8.59V PPBUS_S5_HS_COMPUTING_ISNS = 8.59V PPBUS_S5_HS_OTHER_ISNS = 8.59V PPDCIN_G3H_ISOL=14.82V PPDCIN_G3H = 14.82V PP3V42_G3H = 3.418V PPVRTC_G3H = 3.347V PP5V_S5 =...

Yes, old board with GPU issue. I've been pulling components from it for last few months for other repairs.

I noticed the values changing between hot and cool board. I removed U7000 last night and checked it this morning. I'll continue playing with this, but being an old board, I'll work on it when I have time. My biggest issue is not being able to compare this to a working board. Appreciate your...

I removed C6952/53 and measurements dropped slightly. SMBUS_SMC_BSA_SCL = 0.510 SMBUS_SMC_BSA_SDA = 0.522 Removed U7000 now getting: SMBUS_SMC_BSA_SCL = 0.597 SMBUS_SMC_BSA_SDA = 0.698

I did not check when u7000 was removed. BIL not connected. With D6950 removed... SMBUS_SMC_BSA_SCL = 0.517 SMBUS_SMC_BSA_SDA = 0.532

SMBUS_SMC_BSA_SCL = 0.519 SMBUS_SMC_BSA_SDA = 0.535 Thank you.

My bad on the diode "v" (edited the above) . Just to clarify, for the above diode reading, board was not connected to power. Could anything else be pulling down the voltage on PPBUS_G3H or is this most likely a bad SMC? Thanks for the guidance. Much appreciated!

Replaced u7000 and now getting steady green light. 12.3V on PPBUS_G3H which seems a little low. Board not connected to battery. diode mode(red probe on GND) SMBUS_SMC_BSA_SCL = 5.2 SMBUS_SMC_BSA_SDA = 5.3 Voltage... SMBUS_SMC_BSA_SCL =3.4v SMBUS_SMC_BSA_SDA = 3.4v PP3V3_S5_AVREF_SMC=3.3v...

Looking at a 2009 macbook pro LB 820-2530. No light on charger no ppbus_G3H u7000 pin resistance on: 17/18 => 20.7 27/28=> 20.5 voltage on... pin 1 = 16.78v pin 2 = 16.78v pin 3 = 4.02v pin 19 = 5v pin 20 = 5v pin 21,23,24 =0.7v ping 25 = 4.5V Need to replace U7000 as does not appear to be...
