I've got this problem with a "Lenovo Legion Y520-15IKBN". I bought the device during the summer of 2017 and had no problems in the first 4-5 months but I am dealing with this problem since the spring of 2018.
-The laptop freezes only when it is charging.
-It does not freeze in BIOS setup but freezes anywhere else ie. safe mode, even while installing Windows(happened twice)
-When it freezes screen remains where it was before but the device does not respond to anything(keyboard or mouse, closing the lid, power button[just hitting not pressing long])
-When it freezes I have to hold the power button to shut it down and start it again.
-Plugging the charger in and out, closing and re-opening the lid, waiting 14+ hours does not help to unfreeze it.
-It takes about 10 minutes to an hour to freeze when I plug the AC adapter in.
-It never freezes when the AC adapter isn't plugged in.
Things I've tried but failed:
-Tried Windows 10 and Linux(Both froze even while installing them once or twice)
-The authorized service said they fixed the motherboard
-The service replaced HDD and SSD
-I asked the service to change the device with a new one but after they tested it, they said it had no hardware failure so they can't change it. The device was still freezing after they formatted it with their own Windows 10 software.
-Tried upgrading all drivers (Today upgraded the BIOS to Jan 18 update)
I wanted to take your advice before losing all hope. Thanks in advance!

i had the same problem as you have but after much investigation i finally found out it was not a hardware failure
it was a software conflicts between windows & one of the drivers
check out my post
also your problem is kinda weird,i never get any freezing during OS installation because there is no point to get freeze when windows haven't installed yet
i think you should test your AC adapter maybe this one is causing it. (based on what you said and the problem is only occurr when AC is plugged)
also i suggest you to go and downgrade the bios to the version when you bought the device
try to downgrade the windows and drivers to the first day of device (or the last time when the device worked properly)

delete it and go to safe mode
from there install this version:
Energy Manager Driver with Yoga Mode Control-190 191
search it through the google
it fixed my problem idk if it helps for you too but its worth to try
i think you might need to check the AC adapter if nothing helps you after all
but first the software is the one to blame

yeah me too
the freezing back for me last night with 190-191 so that didn't fixed the problem but it last longer than before
haven't tested 178-179 but i bet that still have the same problem
currently i uninstalled the acpi driver and prevented the system from installing it via group policy editor and this fixed the problem completely
here is the steps:
2.this adress: administrative templates>system>device installation>device installation restrictions>prevent installation of devices that match any of these device IDs
go to device manager
open the unknown device
in details copy the hardware IDs
should be like this:
inter these IDs in "Show" section of restrictions

First I removed the driver checking the "Delete the driver software for this device." box.
Then I followed those steps as i showed in the image above. It stll keeps reinstalling itself, did I miss a step?
