Why Your Chromebook Has Red Battery With Exclamation Mark

People buy a Chromebook computer because of its exceptionally long battery life. But unfortunately, issues with your Chromebook battery can arise, like the red battery with an exclamation mark. The appearance of a strange red exclamation mark on the battery indicator all of a sudden has been of concern for many people. This post is intended to solve the issue of why your Chromebook has red battery exclamation mark and how to resolve it.

A red exclamation mark on the Chromebook battery indicates the battery is not charging. To resolve the issue, press and hold the Refresh and Power buttons together for a few seconds to reset your battery connection. If the problem with the Chromebook battery icon persists, try removing your battery for a few minutes to see if it helps.

What does the red exclamation mark mean on the Chromebook battery icon?

If you notice this red exclamation mark on your Chromebook battery, one of the common reasons is that the computer battery is not charging correctly or the battery needs changing. There are possible ways you can resolve this, either by resetting or changing the battery for a new one. 

To resolve the issue, we will take you thru some possible reasons why this happens and ways to fix the red exclamation on laptop battery issues. But if our approach does not work for you, your battery is probably bad, and you will need to replace it immediately.

Why do you get the red exclamation mark on your Chromebook battery icon?

Usually, this indicates that the battery needs to be changed or that the device will not function adequately unless it is plug-in correctly.

This indication or mark that you see also indicates that your battery is not functioning properly. This means that your device’s battery begins to degrade due to prolonged use. This can also occur due to faulty charging or overcharging the device. You will need to change your battery to resolve this issue. To maintain the life of your battery, you must adhere to safety precautions. 

Also, these Chromebook computers come with a charging cable. Using anything other than the original cable or a cable that does not produce enough or higher voltage than the specification can cause the red exclamation flag to appear. 

How to fix Chromebook red battery with exclamation mark

If you have noticed the red mark on the Chromebook, here are some possible solutions to fix it. 

Reset the battery connection on your computer.

Connect the charger to the USB port on your Chromebook, then press and hold the Refresh and Power keys together for approximately 5 seconds. Please keep in mind that this key combination will allow you to reset the hardware on your Chromebook.

Continue to keep the keys in place while unplugging the charger.

After that, let go of the keys, remove the charger from the wall and wait 30 seconds before reconnecting. Then, to start the laptop, press and hold the power button for a few seconds. But if the problem persists, repeat the preceding procedures three or five times to completely reset the battery connection on the computer.

Remove the battery from your device.

Take your battery out, wait a few minutes, and put it back into your computer. Next, connect the charger and set a timer for 30 minutes. It’s OK to disregard the red exclamation point if it appears. Next, replace your Chromebook’s battery and check if the problem remains after 30 minutes to 5 hours to allow the battery to readjust and fully charge before using it. 

Change the battery

If the red exclamation mark doesn’t go away, try replacing the battery and see if the problem remains after that. This shows that your old battery was defective if it didn’t work. Replacing your faulty battery with a new one should resolve the issue in most cases.

Why is the Chromebook laptop connected but not charging? 

If you have fully connected your charger or adapter wires, both to your Chromebook and the wall, with the electrical outlet operational and your Chromebook is still not charging, try the following:

  • Remove your charger from the wall outlet as well as your Chromebook.
  • Reconnect your charger to your Chromebook and then to the power outlet.
  • Charge the gadget for at least 30 minutes before using it again. 

If you have done the above and the Chromebook is not charging, go to the diagnostics menu and choose Troubleshoot. 

No power supply detected on Chromebook laptop.

A Chromebook is a ChromeOS notebook, and with every new technology, you may experience charging troubles. If it has stopped charging, we will try to assist you with recharging your Chromebook. 

First, like with PCs, Chromebooks all run ChromeOS, even if different brands manufacture them. As a result, troubleshooting processes for all ChromeOS devices are nearly identical.

Several variables contribute to non-charging. Consider this:

  • The charger is either frozen or not connected properly.
  • Your wall socket may be broken. Try another outlet, and if it’s linked to a light switch, turn it on.
  • If it hasn’t changed in a long time, this implies that it might be slow to start.

These are only a few points to consider. Often, troubleshooting the items above will save you much time finding a solution.

How to Fix Charging Issues on a Chromebook

Fixes for Non-Powered Chromebooks

Check the charger cables and plugs.

The physical layer is always the first place to look for issues. However, this indicates you should inspect the charger itself, especially if this is a new issue. 

  • First, make sure the AC adapter is properly connected to the wall. The prongs might easily come out of the sockets if you move the laptop around a lot.
  • Suppose you have a good connection, then try output. Most outlets have two sockets. Connect the AC adapter to the adjacent socket if you have a tester. If you need to, unhook everything to see if the original socket is broken.
  • Ensure all the connecting cables are tightly connected at their respective entrance locations.

LED Indicator Lights

Most Chromebooks include an LED light that flashes when they detect a charger. Depending on the brand and model, these should be easy to recognize.

  • If you see a light, your Chromebook is charging. Wait 20–30 minutes before turning on the laptop. If your Chromebook is making noises, but the screen is black, it might be a screen problem or something else.
  • If the LED light doesn’t come on, but the laptop’s bottom heats up, remove it immediately to avoid future issues. 

Reset embedded controllers

Your Chromebook may be frozen and not responding to the charging connection. Try performing an embedded controller reset while the laptop is still plugged in if this happens.

  • Make sure your Chromebook is turned off.
  • Connect your charger and Chromebook.
  • Hold the power and refresh buttons on the keyboard.
  • When your Chromebook turns on, let go of the refresh button. The Chromebook should power up now. Once on, reset to continue. 
  • Use the power key and volume up key to reset the Chromebook tablet.


Hopefully, your Chromebook is now completely functional. If it isn’t, contact the manufacturer. You may have a warranty or require specific device troubleshooting. Thankfully, Google has compiled a list of manufacturers and their phone numbers.
