Re:

Hi, Thanks for reaching out. We would recommend performing a BIOS update to rule out the possibility of this causing the issue. You can use this link to go directly to our support website to find the most updated BIOS version for this computer. https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/ideapad-z-series-laptops/ideapad-z5....

In addition, do you know if you have the FRU Part#: 102500541 or 102500540 listed on the CPU packaging? The reason for this is that the BIOS has a whitelist and only tested FRU's will work (see page 87 of the manual for more info https://download.lenovo.com/consumer/mobiles_pub/lenovo_z410z510z510touch_hmm.pdf).

Re: Re:

It is important to have the latest BIOS when changing CPUs..  I would also suggest booting into the BIOS with the new CPU (if possible) and load setup defaults.
