Re: Ideapad Y700- 15ISK Screen has horizontal lines that blink

Hi there, Jason -

 

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

 

This has been commonly linked to a faulty connection somewhere along the LCD cable (connections/cable itself):

If you notice the flickering resolving itself after flexing the screen (lightly) or that the problem only occurs in certain orientations then you are likely experiencing a wiring issue.

 

If the screen only flickers at the start screen then it is possible that your drivers are out of date and you will want to update those before continuing. Please go through HMM (Hardware Maintenance manual) for better understanding.

 

Please click here for latest video drivers.

 

Click here to know how to speed up the computer.

 

Update us how it goes.

 

 

 

 

Regards,

The screen flickers randomly and especially on google chrome even and google chrome is up to date. I'm gonna try to update NVIDIA from your link and see how it goes

Just to check, if you boot the machine in Safe Mode (or Safe Mode w/ Networking), are you able to open files faster?

 

Things that you can try:

 

  1. Follow this guide(option one) on how to optimize the HDD
  2. Check this guideon how to manage start up programs that might be eating up system resources
  3. Ensure that you set the power options to High Performance so the system will run at max speeds.
  4. [Optional] Use PC optimizations software’s (e.g. CCleaner)

Also, I would advise you to turn of Windows Aero   Computer -> Properties -> Advanced System Settings -> in Performance label press "Settings" -> Check Adjust for Best Performance 

 

Update us how it goes.

After I did the adjusting for best performance, there is less flickering. Also I am using Windows 10, not 8
