Chosen Solution
I replaced my keyboard backlit and speakers (all), recently after watching ifixit and other youtube videos guidance. Everything went smooth, backlit was mesmerising for few days, until few days ago, I realised the laptop won’t sleep when the lid is closed. It eventually does due to Mac OS auto sleep after no activity, but it doesn’t wake either when lid is opened. I reopened back cover, changed hard drive cable from 2012 to 2011, re-opened and closed battery connector and indicator, all other connections, checked magnetic field on screen and on top of SD card socket. Everything is fine. I still don’t get the MacBook Pro to sleep/wake with the lid mechanism. I find it annoying because after replacing a part, a new part or repair is required. I can keep going, but the battery is draining when I close my laptop during night time. It was not like that before, it stayed more or less same during whole night because it was sleeping. I am worried if this issue may have effect on the board sometime in future. Can anyone help in this regard? Update (10/19/2019) Okay @arbaman and @danj, looks like I have to get an indicator cable replacement. I will get back on that and if it functioned properly.
I’d imagine if you took the trouble to replace speakers and KB backlight it was for a good reason..was it liquid damaged ? Check the small sensor connector next to the battery, it’s a bit fragile and might have been damaged when you removed the board. If there was liquid damage the sleep sensor/battery indicator may have been damaged electrically too.
Hello Vijay, I need your help.. I have a Macbook Pro 15’ 2011 I cleaned it and I did Heat Sink Replacement .But after that the doesn’t sleep when lid is closed :( I checked all cables and battery charge sensors, and they are functioning normally. Did the imam move? I tried to do this test procedure(https://www.youtube.com/watch?v=eRcWeVTy...), but I was unsuccessful, it seems there is no magnet there. What do you recommend me to try? Which component do you replace to get back up and running? This (https://pt.aliexpress.com/item/400026515…) ?
