Hi!
I would like to try unlocked BIOS for my Y520-15IKBN (7700HQ, 1050 GTX, 8gb*2). Interested in overlocking CPU/RAM, tweaking fan speed etc.
Can I have instructions for how to BIOS dump properly please?

Hello.

I wanted to unlock the hidden bios settings. Please help me.
Lenovo Y520-15IKBN 80WK

P.S. The dump is read by the programmer. I found two flash drives and read both.

Hi. Yesterday i bought Intel AX201NGW wifi card. But my laptop Legion Y520 is not identificate. Can you make mod bios to work this card with Y520?

Hi,
I am a software engineering student, and my laptop has been underperforming lately.
Mainly the CPU is the problem, I was thinking about buying a laptop with a better CPU, but I don't have the money yet for that, so I would like to try some overclocking. I have done some undervolting in the past for this CPU using IntelXTU to prologue battery life, but now I would like a bit more power out of it. IntelXTU does allow me to change voltage but not frequency or anything else.
The processor is an i5-7300HQ, 3.1GHz max boost.
I have lots of room in terms of thermals: I get @60 C while undervolted and @ 65-68 C normal voltage, while running a stress test like Cinebench or Blender.
The bios version is 4KCN45WW
Please & Thank you
