If your HP Laptop has a dark display with no light, ensure the notebook is powered on and has warmed up. Verify the power supply is working. Make sure the SDRAM modules are properly installed. Adjust the display brightness. Press Fn+F5 several times. As a further check, try connecting an external monitor. The cause may be a display cable connection, SDRAM modules, CPU module, display assembly, or the motherboard.
