System is only two week old. My PC is connected to a Samsung HD monitor via HDMI. The lid of the PC is closed when connected to the external monitor. When I reboot the system with the lid closed, the system in non-responsive and wont' reboot. The only key that woks is the Caps Lock. I need to power-off the PC and restart using the power button with the lid open. The system boots up with the lid open and then transfer the video to the external monitor. I have tried everything, including updating all drivers, Windows updates, reading plenty of forum advises and speaking with Dell, who provided little to no support. I have updated the driver in the "ACPI lid" properties via device manager and edited the regedit.exe command to create a Lid always open "DWord" with a value of 1, but nothing worked. Other than having the PC lid open at all times in order to reboot without shuting-down, any other suggestions?
