MacBook Pro don't sleep, stuck on load screen while using

Hi everyone I got this 2015 MacBook Pro retina 15 inches.

It don’t enter in sleep mode when lid is closed, either with apple menu - -> sleep . it do absolutely nothing. I changed the ssd and put in a new one with a fresh Mojave install, so no software related, but if I run safe mode sleep mode works perfectly (even with a external display connected, so I exclude a gpu problem).

Another problem with this Mac it that while using it randomly stuck on boot loading (yes, I have a normal application open and it go back to black screen with white apple and progress bar, nothing move more for hours). This also don’t happens in safe mode.

I don’t have any idea of what is happening here

Update (02/04/2020)

OK. I replace hall sensor.

Same issue!

Any ideas?

I noticed some artifacts when system is booting, the apple logo is flickering a bit. maybe we have a GPU fail? welcome back AMD ... We are back in 2011 %#*@

UPDATE:

As I said this morning I replaced the hall sensor, without any hope of success, only because I got a replacement and I wanted to try everything without giving up.

After that, I have the same identical issue. I don’t perform PRAM or SMC reset (as I said, I don't believe in this fix).

I use the MacBook as normal, I forgot it with power on (of course I don’t have sleep mode) so the battery completely drain an the MacBook turn of itself. I plugged in the charger and let it charge for a couple of hours and when I power it on I see the black screen with “your computer shut down for a problem” and now everything works great, sleep mode is OK, closing the lid works and everything looks good.

So, I have to believe that hall sensor could be the solution (but without the PRAM and SMC reset), or that is somehow related with battery?

I will update the post if the problem reappears.

Thanks

Hi,

Sleep problem goes away with new hall sensor, now I have random shutdown, plus always crash when I connect an HDMI monitor. I have different kernel panics

service: com.apple.logd, total successful checkins since load (200 seconds ago): 21, last successful checkin: 0 seconds ago

What make and model is your SSD drive? Is it an M.2 held in an adapter frame?

da

nope, both are original samsung ssd , both give problems. both works good in other MacBook

im downloading now Catalina to see if something change.

catalina installed, same issues

Let’s check the lid sensor to see if its working correctly: You’ll need a rare earth magnet and a steel paper clip (one that can be grasped by the magnet) and some masking or colored tape.

Using the paper clip slide it along the face of the screen along the edge Left edge somewhere along it the paperclip should get snagged by the hidden magnet carefully food down the lid so you can transfer the location using a piece of tape to mark the upper case. Now with the system running slide the magnet along the face of the uppercase make sure the location you’ve marked is where the screen turns off, do make sure you check the whole edge as different models have the magnet at different places.

I’m suspecting someone replaced the display and used the wrong version or they placed the magnet into the wrong location when they replaced the LCD panel alone.

If the screen does not go into sleep mode at all that points to a bad Hall sensor which is located on the backside of the logic board as seen here

hi, thank you so much for the help, but as I say before the lid work perfectly in safe mode, if I close the lid it go to sleep. in normal mode I can't go to sleep anyway, from apple menu it doesn't work,closing led don't work.

So, I don't think can be useful to test the hall sensor if it works in safe mode, however tomorrow I will give a try. thanks again

I got a spare a1398 board for harvesting, it's late 2012 you know if hall sensor could be the same?

Before I dig into logic board issues I always double check! This is such an easy test I do strongly recommend it. I've encountered all possible scenarios! Bad Hall sensor is still the least likely. Getting an idea where the magnet is in the lid and the alignment to the Hall sensor is the first thing I check. I've seen to many systems people had the display replaced only not getting the correct one or the magnet was forgotten or not in the correct location for the given series!

Just because you can use the menu control to enable sleep doesn't prove or disprove you don't have a software issue. There is a few apps like Amphetamine which are designed to prevent your system from going into sleep mode. Did you install it? Or is this a used system which the previous owner might have?

dan, im not sure I'm explained right the problem here (im Italian and maybe my English is poor).

SAFE MODE

everything works well, never crash, I can stop by apple menu, I can close lid, go to sleep, reopen, wake up.

NORMAL MODE

occasionally crash (from nothing it go to black screen with apple logo and loading bar, the same that you see when os is booting, I can regulate screen brightness and keyboard backlight, everything is very weird), can't stop by apple menu, close lid screen don't stop at all.

I also noticed that when I try to stop the Mac with apple menu in normal mode the keyboard backlight turn off instantly but nothing else is happening.

I tried with two different ssd with totally fresh OS X install, also tried with Catalina, everything is the same.

Thanks again

OK, let's look at this differently! What is the difference between Normal and Safe Modes

In Safe Mode the bare minimum of drivers are loaded! In most cases that can useful to know when the dedicated GPU has problems. As its driver is not loaded!

So with knowing that you maybe facing something totally different here, nothing to do with the Hall sensor at all!
