The first thing you can do to fix such a problem is to restart your laptop. Because the monitor is working and the screen is not, the issue could be with the operating system such as Windows 10 or 8.

Therefore, when you restart the laptop, the issue between the OS and BIOS will be fixed, letting your laptop start back usually and show the display on its own screen. Moreover, it will also select those damaged drivers or other files that stop the laptop from starting.

  1. First, you need to remove your laptop’s battery.
    Ensure that no power cord, electric wire, or charger is plugged in with your laptop.
  2. Press and hold the power button on your laptop and wait until all the static electricity must release.
  3. Now, plug in the laptop charger without putting the battery inside. Make sure the laptop’s charger light is on. And when done, press the power button and see if this fixes the issue with your laptop.

Hopefully, it will fix the issue. But in any case, if it doesn’t, go for the next step.

Method 3: Update Graphics Drivers:

Can you see the laptop window still on that external monitor of yours? If you do so, you can fix something internally, which is based on improving the graphics drivers of your laptop.

Go for downloading the latest graphics and display drivers if you are currently working on Windows 10 operating system.

And when you will download and install them, restart your laptop. This time your problem will be fixed if the missing drivers cause it.

Method 4: What If It’s A Hardware Issue?

Not just the software. But the problem could also occur due to a hardware issue. Suppose your laptop is facing two issues right now based on its hardware. These are given as follows.

  • Either the display is broken.
  • Or the laptop’s LED bulb has been damaged.

Suppose you are facing any of these issues. In that case, there is a need that the laptop will only be fixed externally, and technical knowledge is required to do something like this. But you have the following solutions to try if you want to fix something like this.

If the laptop is in warranty—Be sure that if your laptop is in warranty and got this problem, send it back to the brand from where you have purchased it. They will fix everything for you.

If the laptop is not in warranty—On the other hand, consulting with a nearby computer expert would be the best thing to do if the laptop’s warranty has expired and you are facing this issue.
