Lenovo y520 completely freezing randomly only when AC adapter plugged in

Hello,

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 problem:

-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!

Re: Lenovo y520 completely freezing randomly only when AC adapter plugged in

Hi

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

 

https://forums.lenovo.com/t5/Gaming-Laptops/Hard-freezing-with-my-laptop-Lenovo-Legion-Y520-15IKBM-G...

 

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)

Hi.
When I delete the driver, it re-appears when the windows is restarted. Couldn't find any solution for that. How did you delete it?

And how can I find older bios versions? There is only the latest one available in download section.

Thanks a lot!

Found a way to delete the driver. Also downgraded the bios to the oldest version I could find which is 4KCN40WW. Unfortunately, these solutions did not work for me.

Re: Lenovo y520 completely freezing randomly only when AC adapter plugged in

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

Hello,

I deleted it and installed 190 191 version from this link:
https://support.lenovo.com/tr/en/downloads/ds500484

But still the laptop freezes after a while when it's plugged in.

Hi,

I installed 178 179 version and it didn't freeze for about 12 hours, I thought this solution has fixed the problem but after I restarted the laptop it froze after 3 hours. It has never gone this long without freezing before. I think we may be getting closer to fix the problem.

Re: Lenovo y520 completely freezing randomly only when AC adapter plugged in

Hi

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:

1.inter gpedit

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:

 

ACPI\VEN_VPC&DEV_2004
ACPI\VPC2004
*VPC2004

 

inter these IDs in "Show" section of restrictions

gpedit.pngFirst 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?

Re: Lenovo y520 completely freezing randomly only when AC adapter plugged in

Currently trying this while waiting for your reply:

Followed these steps:
1-Update driver in driver manager
2-browse my computer for driver software
3-let me pick from a list of device drivers on my computer
4-Unchecked "Show compatible hardware" and installed "System interface foundation V2 device" from the new items that appeared.

I have no idea what I am doing but wanted to try it. Will be reporting if this solves the issue.
