To fix a dead laptop screen, start by checking the power supply and ensuring that the battery is adequately charged. Next, try connecting an external monitor to verify if the issue is with the screen itself or a different component. If the external monitor works, your screen may need replacement. Inspect the laptop's display cables for any disconnections or damages. If comfortable, reseat or replace these cables yourself; otherwise, consult a professional. In some cases, a hard reset might resolve the issue, by turning off the laptop, removing the battery and power cord, then holding the power button for 30 seconds before rebooting.
