Experiencing a black screen on your Chromebook can be a distressing incident, especially when you’re not quite sure why it’s happening.

This issue could stem from factors such as overheating or charger malfunctions, among other things.

What Causes a Chromebook Black Screen?

The causes of a Chromebook’s black screen can include issues with the power supply or charger, incorrect screen brightness settings, overheating, and damaged hardware.

Issues with power supply or charger

Your Chromebook may have a black screen because of power supply or charger issues.

First, make sure your charger is plugged in correctly.

loose cord can cause problems. Also, check if all parts of the charger are put together correctly.

Sometimes, pieces come apart and need to be fixed again. Don’t forget to test with a different charger too. This step lets you know if your original charger is making the screen go black.

Incorrect screen brightness settings

Sometimes, if your screen looks too dim or even black, it may be due to low brightness settings. T

uning up the display brightness can help fix this issue.

Adjusting the visibility settings on your Chromebook is easy.

Use the brightness control key on your keyboard to boost the light levels.

Overheating

Chromebooks can get hot and cause a black screen. This is called overheating.

Hot temperature or thermal overload happens when the Chromebook works too hard and builds up heat. 

If the Chromebook gets too hot, it may turn off to cool down. Just like you need to rest in a cool space after playing under the sun for too long! Unplug your Chromebook if it’s hot, then wait about 30 to 40 minutes before use again.

Damaged hardware

Damaged hardware can also cause a black screen.

This could be due to a physical issue with the screen, such as a malfunction or failure.

If you suspect that the hardware is damaged, try connecting your Chromebook to an external monitor.

If the external monitor works but the built-in screen doesn’t, there’s likely damage to the hardware. 

How To Troubleshoot Black Screen On A Chromebook?

1. Check the power supply and charger

One of the things you should check is the power supply and charger.

Make sure that the power cable or charging cable is securely connected to both the Chromebook and the electrical outlet.

Double-check that it’s properly plugged in and that there are no loose connections.

Sometimes, simply reseating the charger can fix the problem.

If everything seems fine with your current charger, try using a different one if possible.

This can help determine if your original charger is causing the black screen problem.

Keep an eye out for any signs of damage on both the charger port and power cord as well.

2. Adjust screen brightness

Low screen brightness can make it difficult to see anything on your Chromebook’s display.

By increasing the brightness level, you can improve visibility and prevent the black screen problem.

To do this, press the screen brightness key on your keyboard and check if the visibility improves.

3. Restart Chromebook

You can try restarting it. Simply hold down the power button for about 10 seconds until the device turns off completely.

Then, press the power button again to turn it back on.

This simple step can often help resolve the issue and get your Chromebook working normally again. It’s an easy and quick troubleshooting method that you can try before exploring other options.

Restarting can be effective because it helps refresh the system and clear any temporary glitches that may be causing the black screen problem.

4. Check battery

One possible reason for a black screen on your Chromebook is battery problems.

To troubleshoot this, you can start by checking the battery. Make sure it is properly connected and not loose.

If the battery seems fine, try removing it and then reconnecting it securely.

Another option is to let the battery drain completely and then charge it for at least 30 minutes before turning on your Chromebook again.

Additionally, trying a different charger might also be worth considering if you suspect that the original charger is causing the problem.

5. Allow Chromebook to cool down

The next step you can take is to allow it to cool down.

Overheating can sometimes cause the screen to go black, so giving it some time to cool off can help resolve the problem.

Just unplugging your Chromebook and letting it sit for about 30 to 40 minutes should do the trick.

This cooling down period can not only fix the blackout issue but also prevent any further malfunctions.

6. Disconnect external devices

To troubleshoot a Chromebook’s black screen, one simple step you can take is to disconnect any external devices connected to your Chromebook.

This includes peripherals like keyboards, mice, USB sticks, and SD cards.

Sometimes these external devices can cause conflicts or malfunctions that result in a black screen issue.

By detaching them from your Chromebook, you may be able to resolve the problem.

So if you’re facing a black screen on your Chromebook, try disconnecting any external devices first before moving on to other troubleshooting steps.

7. Use a different charger

Trying a different charger can help you determine if the original charger is causing the issue.

Sometimes, chargers can malfunction or become incompatible with the Chromebook, leading to screen problems. By using an alternative charger, you can see if that resolves the black screen problem and allows your Chromebook to start working again.

So, don’t hesitate to test out a different charger if you’re experiencing this issue.

8. Reset Chromebook hardware

You can try resetting the hardware.

This is an advanced troubleshooting step that can help resolve the issue. One way to reset the hardware is by performing a factory reset or hard reset.

This will restore your Chromebook to its original settings and may fix any software problems causing the black screen.

Keep in mind that performing a factory reset will erase all your data, so make sure to back up any important files before proceeding.

9. Let the Battery Run Out

Here’s what you can do:

– Allow your Chromebook’s battery to deplete completely.

– Plug in the charger and let it charge for at least 30 minutes.

– Turn on your Chromebook and check if the black screen problem is resolved.

10. Check for Updates

– Go to the “Settings” menu by clicking on the gear icon in the bottom right corner of the screen.

– Click on “About Chrome OS.”

– Click on “Check for Updates” to see if there are any available updates for your Chromebook.

– If updates are found, click on “Restart to Update” and let your Chromebook install them.

– Once the updates are installed, check if the black screen problem is resolved.

Remember to regularly check for updates as they can fix software bugs and improve performance.

11. Reset Chrome Flags

Chrome Flags are experimental features that can affect the performance of your browser.

Here’s how to reset them:

– Open the Chrome browser

– In the address bar, type “chrome://flags” and press Enter

– On the flags page, click on the “Reset all to default” button

– Restart your Chromebook

By resetting Chrome Flags, you can revert any changes or customizations that may have caused the black screen problem.

This could potentially fix the issue and restore normal functionality to your Chromebook.

Remember to only perform this step if you are comfortable with experimenting with browser settings. 

12. Perform a Powerwash

Here are the steps you need to follow:

– Back up any important files or data before starting the Powerwash process.

– Go to the Settings menu on your Chromebook.

– Click on “Advanced” and then select “Reset settings.”

– Click on “Powerwash” and confirm your choice.

– Your Chromebook will now be reset to its original factory settings, erasing all data in the process.

Remember, performing a Powerwash should be considered as a last resort if other troubleshooting methods have failed to resolve the black screen issue.

13. Seek Professional Assistance

If you’re unable to troubleshoot the black screen issue on your Chromebook, it may be time to seek professional assistance.
