按下开机键后，屏幕没有反应，黑屏。键盘灯不亮，背面的苹果LOGO灯不亮。

只有风扇声。

去授权店进行检修说是屏幕出问题了，后面又去直营店天才吧进行检修，说是可能和系统有关。但是我已经进行过抹盘重装，系统无论是升级到10.4还是10.15都会出现这个问题。

另外我装了双系统，在windows下面没有出现过此种情况。

黑屏状态如图（背光正常）

Thank you

Battery Terminal & Data PORT. On my MacBook Pro 16” M1 Max, snapped off or broke off when putting in new battery and I believe that was the reason why the battery it was not being recognized by the board because of the logic board connector,

I’m in desperate need for someone who can help me fix or find the parts name or number

(Battery Terminal & Data PORT)

because I’ve tried, can’t find or get anything

Can you please call me I’m looking for an adapter that allows me to plug in a 2016/2017 non touch bar SSD drive to either a USB-A or USB-C port to read and test drives externally.

I would need about 10 of them.

I've torn the lid angle sensor while trying to clean the inside of my computer. I've attempted to work around this by putting the computer to sleep before closing the lid however the screen turns back on as soon as it is closed. Also strange that the screen will stay on indefinitely until the battery is dead, even though i've changed my power savings settings are to turn the display off after one minute of inactivity. Its odd because if the sensor is broken and the computer thinks that it's still open, it should turn off after inactivity. The only solution i've found is to shut the computer off before closing it which is not ideal. Finally, i've found replacement cables online however i've been reading that this will need to be calibrated by a professional? Can anyone confirm if this is true?

Thank You

Thank you all for the wealth of information. Just to provide an update to you all, i made sure to purchase a used angle sensor that was taken from a working computer and replaced it on my own. So far everything works as it should!

I have a problem with a Macbook Pro Mid-2012 (A1278). When I turn it on, the fan immediately starts spinning at maximum speed. When it gets to the login screen, I log in, and after two seconds of loading it shuts down. I've already tried to reset SMC and PRAM, but that didn't help.

My guess would be that it is a thermal sensor not working properly? Does anyone know were the thermal sensor is located? Or any other ideas?

Thanks!

Thanks a lot for your help so far.

I did a quick inspection on the pins and also the logic board, from what I can see and judge, it doesn't look too bad.

Here are some photos:

I will try to also find someone with the same charger. Although the charger seems to be in quite ok condition and I think is replaced at some point. The only thing I can see is that the chord is slightly squeezed at the top, but I don't think enough to not make it work properly.

I'm assuming that I did not reconnect one of the cables properly on reassembly, so will be opening it back up, and it would be helpful if I had a sense of which cable to look at when I had it open, as the prior teardown was extensive, delicate, and time-consuming.

I used three different teardown guides as there isn't one specifically for this model (1st Gen M1 13" MBP, late 2020). The main teardown guide I used is this: MacBook Pro 13" Two Thunderbolt Ports 2020 Touchbar Removal

Unfortunately not every cable connection is identified.

Is there a map of the internal [microphone] connections available for this (or similar) Macbook Pros?
