    Please provide the exact model of your laptop. Kindly check the steps given below. When was the last time it was working fine. How long it is staying blue? Was it working fine earlier?

    If it was working fine earlier..

    Sometimes a simple system restore will fix the issue.. 

    Try windows x
    click on power shell admin or command prompt admin 
    type rstrui
    chose an earlier date on which your computer was working fine  
    click on next, finish, yes
    It will restore your computer to an earlier date 
    if you get an message - system restore not completed - click on close 
    It will show you all the icons..
    Try and check whether it is working now ..

    If it is still not working..

    Try windows + r - on run type appwiz.cpl

    uninstall the predator sense

    Go to support.acer.com 
    chose your country 
    type snid or chose your model 
    go to drivers 
    Install the predator sense software

    It should work fine

    Kindly go through the details from the link given below

    There could be several reasons why your blacklight is not working, including:

    1. Dead or weak batteries: If your blacklight is battery-powered, check the batteries to see if they are dead or weak. Try replacing them with fresh batteries and see if that solves the problem.
    2. Bulb issue: If your blacklight has a bulb, it could be burnt out or not properly connected. Check to see if the bulb is properly seated and if it is not burnt out. If it is burnt out, you may need to replace it.
    3. Incorrect distance: Blacklights work best when they are placed at the correct distance from the object being illuminated. Make sure your blacklight is the appropriate distance from the object you want to illuminate.
    4. Poor quality or wrong type of blacklight: Make sure that you have a blacklight that emits the appropriate wavelength of ultraviolet light. Not all blacklights are created equal, and some may not be suitable for the task you have in mind.
