Lenovo Legion Y520 performance issues and 100% disk usage

2018-12-14, 12:18 PM

I bought a lenovo legion y520 couple months ago and the performance has been horrible.

It has an i5-7300HQ and an GTX 1060 Max-Q 3GB, 8gb of DDR4 ram and a 1 terabyte hdd.


The laptop is really slow, mainly because the disk and ram are always in high usage even when im not really doing anything and barely any programs are open (only programs that are always open are discord, steam and google). In game the processor is over 85% usage, the disk is 100% and ram is 80-90%.

I have tried alot of different solutions to fix these issues like disabling and/or uninstalling some programs to changing the power settings to max performance. I already have sent this laptop to lenovo once and they changed some parts which did improve the gaming performance, the fps increased from 20 to 40 fps in overwatch on low settings to 50 to 70 in medium settings. I have reset the laptop completely to factory settings twice already and that has not helped at all, i would like to hear if you had some solutions to this problem!

Hi Niko_Annala! Welcome to Community Forums.


We need to know what's using the memory and disk. Go to Task Manager then Open Resource Monitor. Please send a full screenshot of the memory and disk usage, so we could check.
