MSI: Katana GF76
Motherboard: MS-15821 Ver: 2.1
CPU: Intel® Core™ i7-11800H
KBC: KB9548QF
Motherboard in power off state consumes 0.040A. It reacts on power switch and consumes 0,041A. KBC programmed, BIOS programmed, no difference. 3,3V and 5V are working. No liquid damage. Resistance on coils below:...

Re: MacBook AIR 1466 [ 820-00165-A] = Missing "PM_SLP_S5_L"
Yes, nothing is connected to the board, only power supply. Then it cycles two times and go to 0,023A

Re: MacBook AIR 1466 [ 820-00165-A] = Missing "PM_SLP_S5_L"
F7140 = 8,574V, as I said all voltages are fine up to PM_SLP_S5_L based on https://logi.wiki/images/a/af/G3_-_S...ell.drawio.png
Even the battery charging works.Last edited by Lgolebio; 05-15-2023, 07:10 AM.Leave a comment:

It was replaced as I mentioned. And resistance is high.Leave a comment:

Sure.
Board is a little bit dirty with flux, because I replaced a capacitor and a TPS22924 switch.

MacBook AIR 1466 [ 820-00165-A] = Missing "PM_SLP_S5_L"
Hi
MacBook AIR 1466
MB: 820-00165-A
I followed the power scheme https://logi.wiki/images/a/af/G3_-_S...ell.drawio.png. I have all voltages up to "PM_SLP_S5_L" = 0V. When I plug the charger it tries to power on, goes to 0,250A then goes to 0,023A and does nothing. No fan spin.
I'm confused, board looks good under microscope. No corrosion. -
Sony PCG-71211M [no SUS_ON signal]
Hi
Motherboard:
M961_MP_MB MBX-224 [1P-0106j01-8011]
Laptop doesn't start. There is 3.3V on power switch. It reacts on that switch, turns on, but it only gets like 50mA of power. +5ALW is Present, +3ALW is present. No 3V on BIOS memory chip. There is no signal SUS_ON on Super IO.
Resistance to GND on all coils normal (kOhms and Mohms).
