Why Won T Laptop Screen Turn On. Ensure that your PC is receiving the complete power it needs. I just heard only loud beep sound continuously but screen remain black.
If you cannot detect the desktop image then connect an external monitor to the laptop and see if it displays OK when the laptop is turned on. Most laptops have a single cable that provides power and the image to the screen. To find out the reason for the issue you may want to try plugging your device into different outlets in different rooms or use a different.
If it doesnt then you either have a faulty GPU or a faulty motherboard.
Sometimes there is an issue with the power button. Many have experienced it. If your laptop is charged it should turn on the laptop. Normally we just have to press it for a second and the laptop will turn on and start processing.
