Y40-80 Screen is flickering when running on battery

Hi, 

My screen is flickering when laptop is running on battery. I tried all the "solutions" suggested on this board but nothing has helped? When plugged in  there is no flickering .Anyone has been able to fix this issue? My laptop is no longer on warranty and I just recently replaced the battery.

Hi there, Girl   -

 

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

 

Can you try the following?

 

  1. Right click on the desktop and navigate to Graphics Properties > Power > On Battery and set the following settings:

   Power Plans = Maximum Performance

   Display Power Saving Technology = Off

 

   - Sample image

 

  1. Follow this guideon how to disable adaptive brightness.

Re: Y40-80 Screen is flickering when running on battery

When my laptop is charging, there is no issue/no flickering.  

 

However, when it's running on battery below 80%, that's when the screen starts to flicker again. This also happens when it's connected to an external display via HDMI cable.

 

I just spent about $100 changing the battery last month, but my laptop needs to be constantly plugged in, since anything below 80% charge the screen starts to flicker.

 

I've tried all the solutions suggested on these forums. 

 

Next step would be to take it to the computer repair shop to change the screen, but I am skeptical whether this will fix the issue or not.

 

Any suggestion/help would be greatly appreciated.

If system is in warranty, you could visit the nearest service center & get the laptop examined if it’s a hardware issue. Hence I would recommend contacting Lenovo service centres and applying the normal phone techniques to get it replaced promptly.

 

Schedule a Call-back for faster support

During business hours, you may also engage with live chat support.

 

Update us how it goes.
