It would be best to have the screen repaired or replaced as soon as possible to avoid any potential harm to your device. Continuing to use your laptop with a damaged screen may also cause eyestrain and discomfort for prolonged use.
You can contact your laptop's manufacturer or a reputable repair shop for assistance with screen replacement. Alternatively, if your laptop is still under warranty, you may be able to get a replacement screen for free or at a reduced cost.
Remember, it's important to take care of your laptop and its components to ensure its longevity and optimal performance.
