TROUBLESHOOTING

Your computer is sturdy and subject to few problems in the field. However, you may encounter 
simple setup or operating problems that you can solve on the spot, or problems with peripheral 
devices, that you can solve by replacing the device. The information in this section helps you 
isolate and resolve some of these straightforward problems and identify failures that require service.

Identifying the Problem

If you encounter a problem, go through the following procedure before pursuing complex 
troubleshooting:

1.  Turn off your Chromebook.
2.  Make sure the AC adapter is plugged into your Chromebook and to an active AC power source.
3.  Make sure that any card installed in the memory card slot is seated properly. You can also 

remove the card from the slot, thus eliminating it as a possible cause of failure.

4.  Make sure that any devices connected to the external connectors are plugged in properly. You 

can also disconnect such devices, thus eliminating them as possible causes of failure.

5.  Turn on your Chromebook. Make sure it has been off at least 10 seconds before you turn it on.
6.  If the problem has not been resolved, contact your support representative.

Before you place the call, you should have the following information ready so that the customer 
support representative can provide you with the fastest possible solution:
•  Product name
•  Product configuration number
•  Product serial number
•  Purchase date
•  Conditions under which the problem occurred
•  Any error messages that have occurred
•  Hardware configuration
•  Type of device connected, if any

See the Configuration Label on the bottom of your Chromebook for configuration and serial 
numbers.
