I am helping someone with their Dell Inspiron N5050, which has Windows 10 installed on it. The computer will boot up, but I only get a black screen. I did find, that if I closed the lid, reopened, and press the power button, I will get the login screen, and can use Windows 10 normally.
However, you have to repeat this process every time. I found out that the computer boots to a non-existent display on a hunch. I decided to plug in a second monitor, and got the login screen on that second monitor. I then disconnected the monitor, rebooted, went through the process above, and saw only one display listed in Display Properties. However, when I hit Detect, it listed two monitors. I did try to fix this with the following: • Going into Device Manager, and uninstalling Generic PnP Monitor. Hp Graphics Driver For Windows 10 64 Bit there.
• Disabling the 'Quick Restart' option in Power Options >Decide What the Power Button Does. • Checking BIOS for switchable graphics, but there are no video options in BIOS for this laptop.
