[Lenovo legion y530] Latency problems

xilolee · Apr 16, 2020

Try to run verifier again.
I've fixed and added some options to the script:

Unzip on your desktop the file I attached, verifier.zip, and then:
1. Open an elevated command prompt (right-click on windows start button, click command prompt (admin)
2. Type (copy/paste) in it:
  Code:
```
powershell -executionpolicy unrestricted "%userprofile%\desktop\EnableVerifier.ps1
```
3. Press enter
  It will reboot your machine in one second, modify your bcdedit settings and set the necessary driver verifier settings.
4. If you'll get a very fast BSOD after you logged into windows, or after some dozens (tenths?) of minutes, the option resetonbootfail should reset driver verifier settings (and should allow you to boot your machine in a normal state)... But if this won't happen, you'll need to go to safe mode to reset verifier settings. Once safe mode is available, from an elevated command prompt you'll type:
  Code:
```
verifier /reset
```
  Sometimes it is necessary to use a system restore point (or a system image).
Post here the new verifier dump; from an elevated command prompt, launch this command:
Code:
```
md "%userprofile%\desktop\minidump" && copy c:\windows\minidump "%userprofile%\desktop\minidump"
```
And you'll find the minidump file in the minidump folder on your desktop.

Should it look like this?

Nothing happened. Another thing i noticed is i8042prt.sys latency growing while typing on keyboard...

Then let's try all settings and all drivers:

Code:

verifier /all /flags 0x03bfefbf /bootmode oneboot

Vezovi · Apr 17, 2020

System doesn't want to boot after applying this command

I.e, what did happen?

xilolee · Apr 17, 2020

Never mind... Let's try "only" standard settings (and all drivers):

Code:

verifier /all /flags 0x001209bb /bootmode oneboot

Lenovo logo appeared and this windows loading circle has kept spinning for infinite time

See previous message

Vezovi · Apr 18, 2020

After 12h:

I don't think it will show anything

Vezovi · Apr 18, 2020

Previous screen has been done after 12h on idle.
After hour of browsing internet, watching yt etc.

xilolee · Apr 24, 2020

Any news?

Vezovi · Apr 24, 2020

Verifier didn't find anything. In my opinion its bios/motherboard fault.
On Lenovos forum someone have tested very first bioses for this unit, mixing it with other tweaks and he managed to solve acpi problem partially.

Try to remove everything from nvidia.
Then install the drivers only, i.e. without installing the software, from your laptop support webpage: laptops and netbooks :: legion series :: legion y530 15ich - IT (if it's this)

xilolee · Apr 25, 2020

Any news?

The driver you found, i8042prt.sys, should be (one of) the keyboard driver(s).
(It is also the ps/2 port driver)
If you have another (usb) keyboard to attach to your laptop, we could try to exclude that driver to see what happens (apart from disabling the laptop keyboard).

I Will try as soon as i get my laptop back from Lenovo Service.

Do you already know they won't fix it?

Vezovi · Apr 26, 2020

I messed up with bios settings and it didnt want to boot up, just black screen. I tried to hold power button, clear CMOS, remove battery, nothing helped, so i had to send it.

It came back, they replaced motherboard, but the problem is still there
