Chosen Solution
Hi everyone, Here is my story. My 2011 macbook pro got the Video issues and after some discussion (before the repairing procedure) I managed to get my motherboard changed. But when my mac came back, I noticed some problem of battery (drained over night). I tried to figure it out and found that when I close the lid of my Mac, it doesn’t go to sleep. The software problem seems to be impossible since I totally formatted and reinstall just after the repair. It seems that the magnet on the screen is not strong enough because when I put a magnet on the screen i still find it at the right place and if a use a small magnet near the keyboard, the Mac goes well to sleep as expected. Somebody knows what is happening? It is pretty annoying and the only solution i found is to stick a small magnet to the screen but I don’t know if it is recommended? Tks for helping!
When a MacBook has insomnia when you close the lid and the system does go to sleep when you put it into sleep mode from the menu option without any problems. You’ll want to first try resetting the SMC & PRAM. Follow these Apple T/N’s: Reset the System Management Controller (SMC) on your MacHow to Reset NVRAM on your Mac The hardware cause is either the magnet was not correctly located when the screen was replaced or the Hall sensor is going bad. Rare earth magnets don’t loose their magnetism on their own so thats not the problem. In this case the sensor could be the issue, follow this IFIXIT guide: MacBook Pro 15" Unibody Early 2011 Hard Drive/IR Sensor Cable Replacement. You’ll want to get the full cable assembly as the Hall sensor is part of the cable. Here is the part you want: MacBook Pro 15" Unibody (Mid 2012) Hard Drive Cable - Apple P/N 923-0084. This is the newer version of the cable which is what I recommend.
Hello!! I`m having the same issue you had - did you managed to fix it? Thank you!
I am havin the same problem with MacBook Pro 2016>The magnetic is working on screen.I test it passing a clip paper around bezel ….my problem it would be on lower case. I will try to test with a magnet like you did.
