Legion y530 acpi.sys dpc latency

2019-10-03, 16:01 PM

Hello,

i tested my legion y530 using latencymon and noticed some bad results. Acpi.sys and wdf01000.sys spike to 4ms or even higher once per 5-10 seconds. Hardware is brand new, it happens even on clean windows install, but not that much. The problem can be forced by using Fn+volume up/down or Fn+ touchpad on/off (holding these combinations occurs in constant spike to 4000us). Sometimes i can hear some crackling/popping in audio or mico fps drops due to these latency spikes.

Bios is updated, set to default settings. 

I sent it to service, but they didn't find any problem... 

What can i do to solve this? 

 

I will add full specifiaction and some screenshots/tests as soon as legion is back from service.

Lenovo legion y530

i5 8300h

gtx 1050 4gb

256 SSd

1tb HDD

8gb ram 2666mhz

windows 10 pro

Thanks for response, where can i find trusted version for legion y530? Did find just for y530

 

EDIT

 

Version 8jcn43ww didn't make a difference, still high acpi.sys and wdf01000.sys DPC spikes.

I even feel that mouse movements are kinda delayed...

All drivers from support are installed.

256 ssd + 1tb hdd

So without HDD you don't have any DPC spikes?

i7-8750H

16GB RAM

128GB nvme + 1TB HDD
