[Acer Aspire 5] Screen flickering

I wasn't touching my laptop while having a break and suddenly the screen went black while my other monitor was still on. I restarted it and now part of my screen flickers, which seems to be the backlight.

It is kind of bothering me at the moment, so I was wondering if others have had similar experiences or know how to solve this if this isn't even a hardware problem.

    For some reason, it is (fortunately) now completely gone. I'm still curious what could have caused it though.

    Hi, sounds good that the issue got resolved!
                                 However, coming to the cause of the issue, this might have caused due to unwanted static energy that gets stacked up in the unit. You can also try the below steps if in case if you face any issues with your unit.

    Power Drain


    1)Unplug the AC power adapter.

    2)Press and hold the Power button down until the unit goes off. 

    3)Search for a pinhole on the backside of your laptop, insert a small paperclip in the battery reset pinhole, press and hold it down for 25 seconds. Then release the paperclip and try to turn on the unit and check.




    1.Turn off the unit. When the unit is off completely, press the power to turn on the unit.

    2.Immediately keep on tapping the F2 to enter the BIOS.                               

    3.In the BIOS, press F9 to reset the BIOS to setup defaults.

    4.At the confirmation screen, press Enter for Yes to load the default configuration.

    5. Press F10 to save your changes, and restart the system. Select Yes and press ENTER to confirm.

        You can try the above steps. I hope it is helpful!:)
