Lenovo Y50-70 screen flickering

Hi guys,I've just bought refurbished lenovo y50-70. It's got warranty until 2018. Problem is that my screen is flickering . But not always,it happens sometimes but no when I'm playing the games,only when I'm doing something on desktop ,web etc. I upgraded bios to 3.03 and downloaded the newest intel graphics driver. Can you help me? Thank you

Hi there, Sliziky -

Thank you for writing in to the Lenovo Forum - happy to have you here today.


  1. To fix the flickering problem, you should first check the laptop cables for loose connections.
  1. Another possible reason for the flickering problem in computer screens is interference of magnetic fields from other gadgets. Yes, check if near your laptop, you haven't placed speakers, fluorescent lights, cell phones, radios and any other electrical device. If it is so, you must remove any such interfering electrical gadgets away from your laptop. Studies have proved that cell phones do cause screen flickering.
  1. First of all try and identify when you face this issue, when on Battery power, mainsAC adapter or in both scenarios? Is it for a particular power plan or for all power plans? Also check if this happen when you enter BIOS and in Safe Mode too.

Also -


Does the flickering happen using an external monitor as well? Because if it does you may really need to send it for a repair since it's a graphics card issue.

Does it happen even the laptop is in BIOS as well? While the laptop is in BIOS observe if it will still flicker because if it does it could also the display itself.


Update us how it goes.

Re: Lenovo Y50-70 screen flickering

This has to do with a graphics related issue. I had your EXACT problem. It was fixed by entering the nvidia control panel, selecting manage 3d settings, and then selecting high-performance nvidia processor under global settings. Then restart your computer. It works. It did on mine at least. This disables the Intel HD 4600 graphics from competing with the Nvidia card.

And we're back...
