Solutions for Computer Won’t Turn on with No Display

Technology can be frustrating when things don’t work as expected. One of the most common issues is when a computer won’t turn on with no display. In this article, we will explore solutions to this problem to help you get your computer up and running again.

Check if the power cord is properly plugged in and the outlet is working. Sometimes, the power supply might not be sufficient for the computer to start up.

Troubleshooting steps for a computer screen that won’t turn on

If your computer screen won’t turn on, here are some basic troubleshooting steps to follow:

1. Check the power source. Make sure your computer is properly plugged in and that the outlet is working. If you’re using a laptop, make sure the battery is charged.

2. Check the power button. Sometimes, the power button can get stuck or not work properly. Try pressing it a few times to see if that helps.

3. Check the display settings. If you’re using a desktop computer, make sure your monitor is turned on and set to the correct video input. If you’re using a laptop, try connecting it to an external monitor to see if you get a display.

4. Check for hardware issues. If none of the above steps work, there may be a hardware issue with your computer. Try removing any external devices and unplugging the power cable. Hold down the power button for 30 seconds, plug the power cable back in, and turn on the computer. If that doesn’t work, you may need to take your computer to a professional for repair.

Reconnecting and disconnecting peripherals and monitor

If your computer won’t turn on with no display, try disconnecting and reconnecting peripherals and the monitor. First, unplug all peripherals and devices from your computer, including USB drives, printers, and external hard drives. Then, disconnect the monitor from the computer. Wait for a few minutes before reconnecting everything back. Plug in the peripherals and power on your computer. If it still won’t turn on, try connecting the monitor to a different video input port. If you’re using a laptop, try disconnecting the battery and power adapter, then reconnecting them and turning on your laptop. These simple steps can help you troubleshoot your computer and get it running again.

import os

# Check if the computer is receiving power
def check_power():
if os.system("powercfg /batteryreport") == 0:
return "The computer is receiving power."
return "The computer is not receiving power."

# Check the graphics card
def check_graphics_card():
if os.system("dxdiag | findstr /i /c:\"Name:\"") == 0:
return "The graphics card is working properly."
return "There may be an issue with the graphics card."

# Check display settings
def check_display_settings():
if os.system("control.exe desk.cpl") == 0:
return "The display settings are configured correctly."
return "There may be an issue with the display settings."

# Main function to run all diagnostic checks
def diagnose_screen():

# Run the diagnostic tool

This code uses built-in Windows commands to check if the computer is receiving power, if the graphics card is working properly, and if display settings are configured correctly. The results of these checks are then printed to the console. However, this is just a basic example and a more robust diagnostic tool would likely involve more comprehensive checks and potentially even suggest solutions to fix the issue.

Resetting BIOS settings as a potential solution

Resetting the BIOS settings can solve the problem of a computer that won’t turn on with no display. To do this, first, turn off the computer and unplug it from the power source. Then, open the computer case and locate the CMOS battery. Remove the battery and wait for at least 5 minutes before reinserting it and closing the case. Alternatively, some computers may have a BIOS reset button on the motherboard that can be pressed with a pointed object. After resetting the BIOS, try turning on the computer again. If the problem persists, it may be necessary to seek further assistance or consider other solutions. Note that this solution applies to various types of computers including laptops such as Chromebook, MacBook Pro, MacBook Air, and others.
