Disable Lid switch sensor on Dell Latitude E7450
Latitude E7450
Hello all, I wanted to know if it was possible to disable the lid switch on a Dell Latitude E7450. I want to do this because it is broken and therefore makes the laptop think that the lid is always closed, therefore forcing the screen to turn off. The only way to get the internal display to work are not using the Intel Hd Graphics 5500 drivers and just using Generic Windows 10 drivers, but this is not what I want. I have tried all software-level solutions to no avail, and even worse, there is no lid switch action option in the power management settings in the BIOS. I want to know if it is possible to either,
A) use software program that forces windows 10 to ignore the lid switch entirely
B) Remove the switch
C)somehow fix/reset the switch
Any help would be appreciated...

I ended up just installing Linux, which solved the problem…

Your assumption about how a laptop lid switch works is not quite correct. By default, if a laptop sensed that the lid was closing, it would prepare to turn off power and go into standby sleep mode regardless of what graphics driver you used.
As for your inquiry to disable lid switch, if you are using Windows operating system, just go to Power Options (in Control Panel) and you should see an option for Choose what closing the lid does and uncheck the boxes for sleep, hibernate, lock, your lid switch will behave (do nothing) as your preference.

@Chino de Oro
the issue is the fact that the laptop always thinks it is closed, even when it is open causing the screen to go blank. However, even setting “do nothing” when lid closed in control panel will still turn off the display (but not sleep mode) if the lid is closed. How do I make the screen stay on even if the lid is fully shut?

If you already confirmed that with a disabled lid switch (do nothing) and the display still turned off, that proved my early post, the issue was not caused by lid switch. If it was always closed, you could not operate the laptop even with generic Windows driver.
To have a laptop stays on and in operation mode with the lid fully shut, you can boot it up with a compatible docking station.

@Chino de Oro
would the docking station need to be hooked up all the time?
