Replace reed switch/hall effect on MacBook Pro
I have a Macbook Pro Retina (a1398), and I need some help.
A few days ago I closed the Macbook lid, it went to sleep, but the I opened it back, it never came back on.
I tried to force a restart but the power button did nothing. It seemed like the mac was dead.
I opened the bottom case, disconnected the battery, and connected the power cable and the mac started ... I can ear the mac chime, but the screen turns off after a second and it never shows any image.
I did a PRAM and SMC reset and the problem still persists.
I connected a external monitor and I can see everything on the external screen.
I tough it was a LCD issue, but then i noticed that the keyboard and trackpad stop working a few seconds after the OS boots. If I connect a external keyboard and mouse I can work normally.
So I believe that my Mac thinks it has the lid shut. That's why it shuts down the screen after a second or two when it boots, and when the OS boots, it shuts down the onboard keyboard and trackpad.
I don't know if this mac uses a reed switch or hall effect sensor. I searched Google but I wasn't able to find anything about this macbook model, so i could replace the defective part.
Can someone please help?
Thanks in advance.
Hi Dan thanks for your reply,
The bottom cover has been off since I started having these issues.
Here is the result of CoconutBattery (yes, I let the battery fully discharge on as a test).
Questa è una buona domanda?
