  • The "power on no display" issue in laptop motherboards is a common problem that can be caused by several different factors. Essentially, when you turn on your laptop, the power comes on but the screen remains black, indicating that the system is not booting up properly.
    There are several potential solutions to this problem, depending on what is causing it. Here are some possible solutions:
    1. Check the display: Make sure that the display cable is properly connected to the motherboard and the display screen. Check the display settings in your operating system to ensure that the correct output is selected.
    2. Check the RAM: If the RAM is not properly seated or has become faulty, it can prevent the system from booting properly. Remove and reinsert the RAM modules and check if that solves the issue.
    3. Check the power supply: If the power supply is not providing enough power, the system may not be able to boot up properly. Check the power adapter and the battery to ensure that they are functioning properly.
    4. Check the BIOS: The BIOS (Basic Input/Output System) is responsible for initializing the hardware components of your laptop. Check if the BIOS is properly configured or if any settings need to be adjusted.
    5. Check the graphics card: If your laptop has a dedicated graphics card, it could be the cause of the issue. Check if the graphics card is properly seated and if any drivers need to be updated.
    6. Seek professional help: If none of these solutions work, it may be best to seek the help of a professional technician who can diagnose and fix the issue.
