If the Chromebook will not turn off, leave it open and unplugged in a safe place for 6-7 hours to let the battery run down. Then charge the Chromebook and turn it on using the power button. If the screen still does not light up, it may be broken and need to be replaced.

Failure to Charge ¶ 

The Chromebook will not charge, or will not hold a charge.

Charger Not Operating Properly ¶ 

Be sure the outlet the Chromebook is plugged into has power. Check to make sure the charger is plugged into the outlet and has no visible damage. Make sure the charger is inserted all the way into the charge port.

Faulty Battery ¶ 

If the Chromebook functions with the power cord in, but dies or runs out of power quickly when unplugged, the battery may be dead or dying. Consider replacing the battery using this guide.

Broken or Loose Charge Port ¶ 

If the battery is holding a charge, and the outlet and charger are functioning, then the charge port may need to be loose or need to be replaced.

Weak/Slow or No Internet Access ¶ 

The Chromebook is not accessing the internet, or the connection is slow.

Application Not Running ¶ 

If the Chromebook will not connect to the internet, or shows it’s connected to the internet but does not allow use of internet functions, turn off the Chromebook by pressing the power button for 5 seconds, and then turn it back on.

Too Many People on Network / Slow Bandwidth ¶ 

If your connection is still weak try to use Verizon Wireless Internet. Find and click the wifi symbol on the bottom right corner of the screen. Click on “Activate Verizon Wireless” and sign in to the user’s account. If the user doesn’t have an account, click “Create a New Plan” and follow the instructions given.

Once the user has created an account, they may need to wait five (5) minutes before Verizon Wireless services become active.

Router Not Functioning ¶ 

Be sure the router is plugged into an operational outlet and is turned on. Some routers have front facing light displays indicating quick information. Locate the internet symbol on the router and see if there is any light displaying internet access. If no light is shown and router is turned on, contact the internet service provider.

When using a wireless connection, the internet speed may slow down depending on the distance of the router to the Chromebook. To have optimum internet speed, consider connecting the Chromebook to the router using an ethernet cord.

Wifi Settings Off / Wifi Antenna Not Functioning ¶ 

Locate the Wifi network switch on the bottom right corner of the screen and make sure that the Chromebook is connected to the network. If it displays “connected to (the network name)”, then it is connected to the internet. If this message is not displayed, use the Google Chrome Connectivity Diagnosis App under the application launcher in the bottom left corner to attempt to fix this issue. If the network is not detected, but the router is on, contact the internet service provider for further assistance.

If the Chromebook is still unable to connect wirelessly using these methods, and the Chromebook isn’t detecting any networks nearby, it may have a faulty internal wifi antenna that needs replacing. Consider replacing it using this guide.

Camera Not Working ¶ 

Chromebook doesn’t detect camera, or displays the message  No camera found.

Application Not Functioning ¶ 

Restart the Chromebook by going under the profile picture on the bottom right corner of the screen. Click restart to restart the Chromebook. After the Chromebook has restarted, try starting the camera again.

Personal Settings Incorrect ¶ 

Check if the Chromebook is detecting the camera by going under the camera settings. To do this, go to Settings, and then click Advanced Settings. Under the Privacy section, click Content Settings, and then click Media. Check to be sure the camera appears on the drop down list of available cameras. If the camera doesn’t appear under the drop down list, the Chromebook may have a faulty camera and may need to be replaced.

Faulty Application ¶ 

If under the Settings the camera is detected, try using a different application. If the camera functions in a different application, return to the initial application and go through that application’s troubleshooting help section to detect camera.

If the camera is still not detected by the application, delete and reinstall the application by clicking the application launcher in the bottom left corner of the screen and locating the application to be deleted. Right click on application and click “Remove (application name)”, then reinstall the application from the Google App Store.

Faulty or Broken Camera ¶ 

If the camera isn't being detected under the camera settings, doesn’t appear on the drop down list, or is displaying a distorted image due to a potential crack or other damage, the camera may have stopped working and may need to be replaced.
