29 MacBook Pro 15 2013 Integrated GPU goes sleep itself randomly
Hi there :)
Things what I know and what I did with this MacBook:
- I’ve done SMC and PRAM reset - no changes
- fresh installation latest 10.13.6 High Sierra - no other apps installed
- no magnetic field around
- Apple said their diagnostic tool says MacBook is in fully working condition :/
- to be more weird - I’ve got MacBook Pro 13 2015 and it has problem with wake up after more than 12hrs sleep and it wakes up after about 1-2 minutes everytime - it wakes up instantly if left for about 30 minutes - when left for sleep or even off over night - it will not wake up / won’t on for about 1-2 minutes.
I start to suspect Apple is messing up with all those FIRMWARE updates in High Sierra - there were about 3 of them!
But I am not sure if it is a problem - but - why Apple says MacBook is 100% in fully working condition?
Update (08/22/2018)
.
Here are some additional info: when MacBook goes to sleep - when I press power button very short - it is switching on “from beginning” - it is like it is not going to sleep - but switch off itself

You stated you did a fresh install of MacOS High Sierra (10.13.6) did you wipe the drive before you installed so nothing was on the partition?
When you say the system goes to sleep randomly was the lid up or did you have it down and using an external monitor?
The magnetic field is only an issue if you put it close to the Hall lid sensor otherwise you could be in a MRI and that wont effect your system ;-}
Diagnostics has its limits! It only tests the inner world of the computer not the outer world like displays and other analog inputs/outputs.
The firmware updates are mostly for malware protection signatures for XProtect which is a good thing! XProtect Explained: How Your Mac’s Built-in Anti-malware Software Works
