If your ASUS laptop's display has suddenly stopped working, it could be a sign of a broken display. This issue can be caused by various factors, such as accidental drops, electrical surges, or age-related wear and tear. A broken display can be frustrating, as it prevents you from using your laptop's main function. However, there are a few steps you can take to troubleshoot the issue and potentially fix it. Firstly, check if the display is simply turned off by pressing the power button or the function keys. If the display remains unresponsive, try connecting an external monitor to your laptop using an HDMI or VGA cable. If the external monitor works, it's likely that the issue is with the laptop's display and not the laptop itself. In this case, you may need to replace the display panel or seek professional repair services. Alternatively, if the external monitor doesn't work, the issue could be with the laptop's graphics card or motherboard. In this scenario, it's recommended to consult a qualified technician for further diagnosis and repair.
