+''Laptop only uses power adapter for power supply and cannot fall back on internal battery''
+
+=== Broken Power Adapter ===
Make sure the power cord is completely connected to the Chromebook. Check for the battery icon on the desktop to see if the battery has begun charging. If the laptop does not register the charge, consider buying a new power adapter.

-If the laptop shuts off automatically when disconnected from the power source, check that the battery is charging when connected. If battery is not charging, consider replacing the battery.
+''Laptop only functions when power adapter is plugged in''
-=== Key strokes not registering ===
+=== Faulty Battery ===
-If you are trying to type but keys are not registering, try cleaning the keyboard to remove any substances such as dirt, dust, or dried liquid. Once thoroughly cleaned, attempt to type on the keyboard. If the keys are still not registering, try pressing down in the exact center of the key. The keyboard sensor pad underneath the keys may have shifted so that keys will only register if hit dead center. To fix this, you will most likely need to replace the sensor pad under the keyboard.
+If the laptop shuts off automatically when disconnected from the power source, check that the battery is charging when connected. The icon of the battery in the bottom right corner of the screen will display as charging. If battery is not charging, consider replacing the battery.
-=== Poor Screen Quality ===
+== Key strokes not registering ==
-First attempt to check the brightness keys located at the center top of the keyboard. If the keys are not responding due to keys feeling unsteady or sticky, please see the section labeled "Key strokes not registering." If the keys seem connected and functional then the problem relies on and under your screen. Damage to the screen will cause issues to the pixel functionality, which in turn correspond to screen quality. Replacing the screen is recommended.

+
+=== Faulty Brightness Keys ===

+
+=== Cracked Screen ===
+
+Visually inspect the screen for physical damage such as cracks and black spots. If there is damage, this will cause a problem in screen display on and underneath the screen. The screen in its entirety will have to be replaced.
+
+=== Poor Pixel Quality ===
+
+If the brightness keys on the top row are connected and functioning correctly then the problem lies with the screen. Damage to the screen will cause issues to the pixel functionality, which in turn corresponds to screen quality. Replacing the screen is recommended.
