== Non-responsive Keyboard ==

''The keys or buttons on the keyboard are not working.''

=== The Keys May Need to be Cleaned ===

The first thing you should do is turn off and unplug your Chromebook. Buy a compressed air duster and blow out the cracks between the keys. Look for any foreign objects, such as food bits, that may be stuck underneath or between the keys. After you finish, switch on your Chromebook and check if the problem is resolved.

=== Keyboard is Defective ===

Plug in an external keyboard and test the functionality. If the external keyboard works, but the keyboard on your Chromebook still does not, you will need to replace your internal keyboard. To see more information on replacing the keyboard, please refer to the Keyboard Replacement Guide.

== Glitching Screen ==

''Your computer screen is acting strange.''

=== LCD is faulty ===

A quick way to verify that the LCD screen is faulty is by connecting to an external monitor. If the external monitor works, then you know that the original LCD screen is faulty. To see more information on replacing the LCD screen, check out the LCD Replacement Guide.

=== Wires Going From the Motherboard to the Screen May Have a Poor Connection ===

Start by removing the keyboard and its surrounding panel. Follow the Laptop Cover Removal Guide for this. Perform a quick visual inspection of all cables connecting the screen to the motherboard. There is a larger black connector in the upper left-hand corner called a LCD cable that connects the screen to the motherboard.  Ensure that this cable attaches firmly to the motherboard, and that it is not frayed in any areas. If the connector is loose, ensure that it is lined up properly and press down firmly.

== Spontaneous Shutdown ==

''Your laptop is randomly turning off.''

=== Overheating Processor ===

An easy way to determine if you have an overheating processor is if the bottom of the laptop feels hot to the touch. This could be caused by being in a warm environment, or not allowing enough airflow to the processor. Turn off the Chromebook for 15 minutes and remove from any warm environment. Ensure it is receiving air flow. After set time, switch on your Chromebook to check if the problem is resolved.

=== AC Power Adapter Unable to Sustain a Charge on the Battery ===

If the laptop works when the power chord is plugged in, but the computer dies as soon as it is unplugged, then the battery is faulty and may need to be replaced. To see more information on replacing the battery, check out the Battery Replacement Guide.

=== Battery Overheating ===

If you are experiencing identical symptoms as an overheating processor, but only when the Chromebook is not connected to the power cable, then the cause could be an overheating battery. Your battery will need to be replaced. To see more information on replacing the battery, check out the Battery Replacement Guide.
