Re: Help needed: 2020 MacBook Pro M1 A2338 (keyboard and trackpad not working)
Did you remove the trackpad from C case, and check the back of the trackpad?
Is it clear at the back of trackpad?
Keyboard working need KBD_INT_L, I2C_KBD_SDA, and I2C_KBD_SCL, which are come through JT400.
Maybe there is a water damage at the back of the trackpad, which cause the problem.
OR, check the voltage of these three line. normal voltage?

NEED HELP, MacBook Air a2337 will not turn on
Hi everyone! I need you help.
I have a broken a2337. After checking, I found out the Wi-Fi module was shorted to ground.
According to ''my own theory'', I removed the Wi-Fi module, I thought it will turn on only without the Wi-Fi function.
After all, I seems that I made a mistake. It will not turn on anymore.
Before I remove the Wi-Fi module, there was a 5V 0.3A short.
Now, there was a 5V 0A.
Before I remove the Wi-Fi module, there was voltage for M1 chip.
Now, there is on voltage for M1 chip.
So,

Re: A2159(820-01598) no image
I have a similar board in my hand. I also think the eDP of the CPU is partial dead.
Is there no chance to repair it without change the CPU?
Thank you!Leave a comment:
