Dell Latitude 9450 — Display Not Turning On Fix
Force restart with power button Try first
Hold the power button for 10 seconds. Release, wait 10 seconds, then press once to power on. Listen for POST beeps or fan spin to confirm the system is alive. If the Dell logo shows, the display was in a sleep fault state.
Boot to Safe Mode and Reinstall Display Driver
Hold Shift and click Restart from the power menu (if accessible), or interrupt boot three times to trigger WinRE. Choose Safe Mode with Networking. In Device Manager, uninstall Intel Iris Xe Graphics. Download the driver from Dell Support and install. Restart normally.
Check Display via External Monitor
Connect an external monitor via USB-C or HDMI adapter. If the external display works, the issue is with the laptop panel or display driver. Press Win + P to toggle display modes.

Common questions
Can I hear Windows startup sounds with a black screen?
If you can hear startup sounds, Windows is loading but the display driver failed to initialise the panel. Safe Mode boot and driver reinstall will resolve this.
Is a complete black screen hardware or software?
If an external monitor also shows nothing and no Dell logo appears, it is likely hardware — contact Dell Support. If only the internal panel is black, it is usually a driver issue.
Can the Latitude 9450 display cable cause this?
A loose or damaged display cable inside the 2-in-1 chassis can cause intermittent black screens. If software fixes do not help, a Dell technician can inspect the cable.
