I have been consistently using an old Windows 10 laptop with a broken screen by plugging it into a monitor via HDMI. I was attempting to start fresh and erase the computer's files, but the computer went in sleep mode while this happened. I turned the computer off, and the next day, attempted to try again. Now, the computer will power on, but nothing is displayed on the monitor. The button LEDs on the laptop, particularly a network connectivity button, keep switching from orange to white every 30 seconds or so. I have tried using different outputs, such as VGA, and have still been unsuccessful. I have entered a variety of key combinations with no luck whatsoever. Occasionally, I see a faint flicker from the screen. I can assure you that there are no internal component issues, only display. How do I fix this? I was planning on waiting for an hour or so and trying again but I would appreciate quick results. Thanks!
