Closed lid sensor not working well

When I close the lid on my macbook1,1 the system does not go to sleep unless I use squeeze the left edge of the laptop. in other words, I need to use moderate pressure to squeeze the lid closer to the keyboard before it will go to sleep.

I presume there is some type of sensor installed in the lid and base. Is this true? If it is true, can I make it more reliable via an adjustment, or is there a part that needs replacement?

Thanks,

Mitch

There is no misalignment between the lid and base when closed. When closed, the front edge of the display does touch first and thus at the location of the magnet there is a small gap about the thickness of one or two business cards. this is the area where I "squeeze" to get the macbook to sleep.

So if it's not an alignment problem, is it possible that either the magnet or sensor has moved or is malfunctioning?

Do you know if the sensor or the magnet is replaceable or is it part of a bigger, more expensive assembly?

I wonder if I just tape a small magnet to that area to keep the Mac asleep. My intention is to just use the MacBook in clamshell mode.

Thanks very much for your help,

Mitch

You could try to remove de display bezel and check if the magnet is correctly installed. If so then the battery charging board may need to be replaced.

My older MacBook a1211 Pro started to shutdown and resume erratically. I ended up removing the lid sensor by disconnecting it from the flat cable under the keyboard. There are 3 connectors, the lid sensor is in the middle.

Just disconnect it. Thank God, it worked !.

I hope many Mac users will benefit from this procedure

Hi Mitch, welcome to iFixit Answers.

A magnet located a the left edge of the display enters in contact with a sensor located on the battery charging board (under the top case) when you close the display, this action triggers the machine sleep function. If your display is a little twisted there could be a gap between the two components causing a bad contact and the macbook sleep issue. Check if your display is closing firmly to the top case. There could be a hinge problem. Was the macbook dropped ?
