How do I repair Lid sensor (hall sensor?) on T470?

2019-02-26, 23:44 PM

So my screen can suddenly blink on and off. It also turned my windows to sleep mode. I suspected screen cable connection but now I'm sure it's the lid sensor. Now it doesn't go to sleep mode anymore since I disabled "sleep when lid is closed" on power settings, now it's only blinks like crazy. When I start touching the area on the right side of my camera, the screen start blinking (don't even need a magnet, only touch!).

 

I think I have messed up my warranty (I cracked the screen, after the lid switch broken tho). I can't search the lid sensor model on the internet, maybe it's integrated with the webcam microphone? Will this be expensive? I can't even find the lid sensor on t470 repair manual. Is the lid sensor located behind the microphone?

Solved! See the solution

You can find the sensor location by finding the magnet under the palmrest.  I take a small steel screw and slide it around the palmrest until it snaps to the magnet.  The sensor is in the lit where it hits that spot.

I have found the magnet but I can't double check the lid switch because i don't have a magnet. The magnet is located right next to the palmrest and so I think the lid switch is the right side of camera.

Is there lid switch embedded inside webcam module?

I don't have a T470 to check, but that's a common place.  With the lids becomming thinner, it is common for camera, saensor and mic to be on the same module

UPDATE: I disconnected the camera/microphone connector and now the problem just stopped, so I guess my hypothesis that the lid sensor is embedded with the camera was correct. But now I can't sleep the computer when I close the lid.

does cracking the screen void camera warranty tho as the camera is malfunctioning before the screen? I have a replacement screen coming and I plan to ask the service center to fix the camera module after I replaced the screen.

The LCD panel is not considered customer-replaceable.
