Just like computers, laptops, and tablets, a Chromebook also runs into a black screen now and then due to various reasons. Most people will be disappointed by the black screen but they often don’t know what causes the problem exactly. And more importantly, they don’t know how to deal with the Chromebook screen black.

In recent years, the Chromebook becomes a more and more popular portable device; its size, appearance, and basic functions are very much like the laptop you use. But some aspects of Chromebook are very different from those of a laptop or desktop computer. Take the unique OS as an example: the default operating system used in a Chromebook (no matter it’s an Acer Chromebook, a Samsung Chromebook, or another Chromebook) is Chrome OS, which is designed by Google.

Run into a Chromebook Black Screen

One of the popular problems Chromebook users have reported so far is Chromebook black screen. The screen of a Chromebook turns black (or blank) suddenly while users are performing tasks on it. This is undoubtedly a terrible experience when you’re in the middle of something, right? What makes things even worth is a black screen of death: a fatal error is detected on your device, causing the operating system to shut down forcibly.

Cause 1: Battery Problems

What you should first think of is whether the battery on your Chromebook is draining out or runs into trouble. The battery is the main power source of a Chromebook, just like a laptop. If the battery is not working well, you’ll find your Chromebook not turning on. The battery issue is one of the popular reasons to answer questions like why is my Chromebook not turning on.

You should connect the charger to your Chromebook and let it charge for at least 10 minutes. Then, try to turn the Chromebook on again. Please replace the battery or charger with a new one if it’s broken.

Cause 2: Screen Brightness Too Low

There’s a chance the brightness of your Chromebook screen is adjusted to a low level that you can’t see any information on the screen clearly. In this case, your Chromebook is working properly, but you just can’t see anything.

All you should do is turn up the brightness of your screen by pressing the bigger cogwheel key on the keyboard. Your screen issue will be solved immediately (you can see information on the Chromebook screen as usual) if this is the problem.

Cause 3: USB Device Issues

If one or more faulty USB devices (USB flash drives or USB disks) are plugged into your Chromebook, various problems may be caused, including the black screen.

You should safely remove all the USB & external devices and then, try to restart the Chromebook to troubleshoot.

Cause 4: Hardware Failure

Please restart your Chromebook and take a look at the lights.

  • If the lights turn on when you press the Power button, but you can’t access the Chrome OS, your hard drive may be damaged/broken. You should try to reinstall the system or try to replace your hard drive with a new one.
  • If no lights turn on when you’re pressing Power, please connect the charger to your Chromebook. However, this may also fail if your motherboard is broken. You should send your device to the manufacturer for a replacement if it is still within the warranty period.

Cause 5: Chrome OS Outdated/Damaged

If you may receive a message like Chrome OS is missing or damaged when trying to start your Chromebook, you should realize that your system is corrupted.

You should go to reinstall your Chrome OS under guidance. Google shows you how to recover your Chromebook on this page.

Cause 6: Overheated Computer

If no lights turn on when you’re pressing the Power button, you can use your hands to touch the bottom of the Chromebook. If it’s very hot, you can confirm that your Chromebook screen is turning black due to overheating.

Please wait for a while (at least 15 ~ 20 minutes) and try to restart the Chromebook again when it’s cooled down. If it starts normally, it means the problem is caused by too high temperature; then, you should use it on a hard surface in the future to prevent overheating.

Cause 7: Chromebook Screen Broken

Sometimes, your Chromebook screen may be damaged physically so you can see nothing on it no matter what you have tried.

You should connect your Chromebook to an external monitor or TV to check out. If the screen is really broken, please consider changing one.
