Hi, I need help fixing this. Any help will be highly appreciated.
Got a macbook air A1932 820-01521-A with the trackpad click not working, the fuse was blown (its never the fuse) I tested the line and seems ok, replaced the fuse and it worked again... all good BUT when I tried to remove the board again I pressed the reset switch (SW6955) next to the battery connector WITH the USB-C power still connected to the board.... I pressed and kept pressed for some seconds twice because the fan started to spin... then I realized why.... 😕
After that the machine wont boot, It gets 20V and start booting it goes briefly until 0.57A the returns to 0.45-0.49A and stays there, after some seconds it restarts the boot process again (watch the video), I dont get anything on the screen. the CPU start to get hot and fan starts spining, I guess it reboots because CPU gets too hot.
The switch SW6955 still gets 3.3V
All the SLPS2R are with the correct voltage.
PVDDCPUAWAKE_SW0 to _SW3 when booting 0.97V then goes to 0.55V and stays there.
PP1v2_S0SW: 1.19V
PP1v_S0SW: 1V
PPVCCIO_S0_CPU: 0.95V
PPVCCSA_S0_CPU: 1.1V
PPVCORE_S0_CPU: 0.84V
PPVCCGT_S0_CPU: 0V
ALL_SYSPWRGD: 1.8V
L7210: 0.844V
L7230: 0.844V
L7230: 6.5 Ohms
L7210: 6.5 Ohms
L7430: 5 Ohms
L7410: 5 Ohms
L8102: 52.4 Ohms
L7030 is 1.9Mohm
Trackpad click still works, no green light on shift key, if I connect an usb to the usbc it gets light but not like it is reading it.
