Lenovo Legion Y520, 7700HQ I7, 16 GB RAM, Samsung 960 EVO, 1TB Seagate.
BIOS version : 4kcn45ww, have tried 4kcn40ww, 4kcn41ww
Please do kindly have. Experiencing problem with 7700hq everytime I put turbo boost on, or put processor power state into 100% , random freeze will occur which is I need to perform hard reset.
It's only occuring if power cord is plugged in. In my understanding turbo boost wont hit on battery.
So I think it happening because the turbo boost, because if I tried to disable the turbo boost the system running relative stable.
Have tried everything possible ranging from:
1. Changing thermal pads and paste
2. Removing RAM, SSD, HDD
3. Reinstalling Windows
4. Downgrading BIOS
5. Change AC Adapter
6. Checking for broken cable etc.
7. Do Memtest, Cputest from Intel, basically any other test passed
Have tried XTU, whenever I click benchmark it will suddenly freeze and need to hard reset. But if I tried stress test it's going well and normal, until the stress test completed it will randomly freeze again.
So please if any magician could help me out, thanks in advance
Additional detail, have contacting the service center of Lenovo.
Change new SSD, HDD, and even new Motherboard. The problem keep persisting. And currently my warranty have already expired. Please kindly help.
