Acer Aspire 7 Screen Flickering Issue whenever I plug in or unplug the charger. How to fix it?

I recently bought an Acer Aspire 7. It's a good laptop overall, but from sometime I've noticed that the screen blinks or flickers whenever I plug in or unplug the charger. Has anyone else experienced this issue or know how to fix it?

There may be several reasons for your laptop screen flickering: Loose or damaged cable connection: A faulty cable connecting the screen to the motherboard may cause flickering.

Outdated or incompatible drivers: If your computer’s display drivers are outdated or incompatible, it may lead to screen flickering issues.

Faulty screen or hardware: A faulty screen or internal hardware component can also cause flickering.
Overheating: Overheating the laptop can cause the screen flickering issue.

Software issues: Some software or apps may cause some problems, leading to screen flickering.
Incorrect refresh rate: An incorrect refresh rate setting may also result in a flickering screen issue.
You can start by checking your HDMI, Display-Port, or USB-C cables. Ensure that the cables are securely connected to both the monitor and the laptop. Make sure that the cable is fully tightened and it doesn’t look
or feel loose.

This applies to all cable types, which can become loose for various reasons. Plug in your system to an external monitor to check if the issue reoccurs. If the problem does not occur on the external
display, it may be due to a hardware issue with the laptop’s screen.

Next is to make sure that the graphic card driver is update. Outdated drivers may cause incompatibility, leading to screen flickering problems. Regularly updating drivers ensures optimal performance and a flicker-free experience.

Also to note overheating can cause hardware issues so, routinely check your laptop’s temperature to
ensure it is not overheating. Make sure you clean any dust or debris from the vents and fans to improve airflow.

My laptop is only 6 months old. Suggest something strong that I can apply instantly otherwise, my last option is the service centre.

Hi Sophiekaile,
Here are a few Troubleshooting Steps:-

1. Check Intel Graphics Settings:
   Right-click on your desktop and open "Intel Graphics Settings".
   Go to "Advanced Mode" > "Power".
   Change the power source from "Plugged in" to "On Battery".
   Uncheck "Display Refresh Rate Switching" and click OK.
2. Update Graphics Drivers:
   Go to Device Manager (search for it in the Windows search bar).
   Expand "Display adapters".
   Right-click your graphics adapter and select "Update driver".
   Choose "Search automatically for drivers".
   If that doesn't work, try uninstalling the driver and then reinstalling it.
3. Check for Loose Connections:
   Carefully examine the display cable for any damage or loose connections.
   If you find any issues, you may need to replace the cable or seek professional repair.
4. Reset Monitor Settings:
   Try resetting your monitor settings to default.
   Adjust color calibration and refresh rate.
5. Consider External Factors:
   Check for any electrical interference or magnetic fields that could be causing the flickering.
6. Contact Acer Support:
   If the issue persists, contact Acer support for further assistance.
7. Check for Battery Issues:
   Try running the laptop on battery power for an extended period to see if the flickering continues.
   If the flickering stops, it could indicate a battery problem.
8. Check for Overheating:
   Ensure that the laptop is not overheating, as this can also cause screen flickering.
