I have Acer Nitro ANA515-52, and currently using Linux on it,

When normally using laptop when adapter is disconnected it works just fine, but when I plug the adapter, it starts randomly flickering after some time, after that it flickers even if adapter is disconnected, putting it on sleep solves the problem but again f adapter is plugged this occurs,

I tried using diffrent adapter but it still happens,I check using both gpus, integrated and gtx1050, same problem exists, so it is not driver or gpu issue, can anybody help me with this problem?

[Edited the thread to add model name to the title]

    It could be an issue with your power, either the power going into the supply is not stable, or the power supply itself isn't stable causing the power being supplied to the laptop to not be stable. When running on battery, of xourse, the battery itself is going to provide good power. Not going to be easy to test unless you have the electronics tools needed to verify both voltage and noise. A typical VOM wouldn't show it unless it was really, really bad. Even a cheap oscilloscope like this one should be enough to show that though. Of course a replacement supply would likely be cheaper. :)

    Hello!!

    @patrick90900

    Your problem is either the eDP cable that is damaged or the actual LED 15.6" screen needs replacing, btw the best reference and retailer of screens for your AN515-52 which is the N156HCE-EAA screen so have a look at their site, also have a look at your OEM screen part number first and cross reference with the screens that they have, as the screen might be on its way out?

    Also, try to connect the laptop with an HDMI cable to an external monitor (as that will give you a definite solution if its the laptops screen or eDP cable?) and see if those screen flickering problems are still there? As screen issues are complex as they could be an issue with the eDP cables plugs and/or tiny power/data wires within this cable, that are shortening out or slightly touching other wires within the eDP cable hence giving that interference as this cable is susceptible to allot of wear from opening and shutting of your laptop.

    Hi @patrick90900 is the plug of your power adapter connected to an earthed wall socket?
    Can you test if the same thing happens by connecting an external monitor or TV?
    Thank you.
    All the best.

    Hello!!

    @patrick90900

    Step 1


    We need to determine whether it is a hardware or software issue..  Turn off the computer.  Tap ( f2 for laptop - dell for desktop ) while turning on the computer.  It will go to bios.  Please stay on the bios screen for 30 mins.  If the display is looking good on bios then it is a software issue.  If the display is not looking good on the bios screen then it is a hardware issue.  


    If it is a software issue try the following the steps..


    Try windows x 

    go to device manager 

    expand display adapter

    right click on display driver - uninstall 

    Restart the computer 


    It should work fine.. 


    If it is still not working 

    Uninstall the display adapter from device manager 

    Don’t restart the computer. 

    Go to support.acer.com 

    chose your country 

    type snid or chose your model 

    go to drivers 

    Install the display driver 


    give a try!!

    Hello

    @LunaNova14

    I tried diffrent os's windows 10, Ubuntu(with integrated graphics), Ubuntu(with gtx105) the issue stayed so it is not software issue for sure.

    Can tell me what hardware issue it is exactly, monitor or EDP cable,

    It occurs when power is plugged in

    Thank you
