  2. There is a green line in my screen ....

    There is this green line unexpectedly appeared on my screen. I've tried multiple ways to get rid of it but, it didn't work for me. I am aware that I might have to get a screen replacement but I'm currently unable to do it... The green line appears even when starting the laptop in the logo screen. Please suggest any way to fix this issue! However I've tried to include a screenshot, but the green line doesn't appear there?

    Blue and green horizontal lines on laptop screen.

    Hi Hoang,

    In most cases, colored horizontal lines on the screen are an indication of hardware failure, particularly with the video and graphics card or the screen itself. The chances of this being software related may be very rare, so we'd like to ask you a few things
    to better assess and isolate the situation and give you the most appropriate advice:

    • Laptop model
    • How old is your laptop/ How long have you been using it?
    • Did you make any significant changes in your system before it happened? (e.g. installing software, changing settings, etc.)
    • Do the colored lines also appear on the screen when you first turn it on (BIOS or boot startup) or does it only appear when you're logged in?
    • Do you encounter any specific error messages when the screen freezes?

    Here are some of the things you can do for basic troubleshooting and isolation:

    • If you have a second monitor, try to connect it to your laptop and see if the lines still appear.
    • Perform a hard reset on your laptop (press and hold the power button to turn it off then remove it from the power supply). This will clear all the residual power that may have accumulated during use.
    • If you installed new software before the issue began, we suggest uninstalling them (if possible) to see if it makes any difference.

    Don't hesitate to get back to us with relevant information if you need further assistance.

  4. I have a green line down on my laptop screen

    Green horizontal line on the screen

    I was connecting my laptop to a
    Smart TV Screen when a horizontal green line appeared on my laptop screen. No prior accident in my laptop happened. Can I troubleshoot anything on my laptop before I resort to screen replacement?
