To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to disconnect the power cord from the wall outlet and allow the internal system components to cool before touching.

If you are having problems with the computer, try the appropriate solutions below to try to isolate the exact problem before calling for technical support.

NOTE: The Drive Protection System (DPS) Self-Test software is available on some models only.

●Check the power LED on the front of the computer to see if it is flashing or listen for a series of beeps emanating from the computer. The flashing lights and/or beeps are error codes that will help you diagnose the problem. Refer to the Maintenance and Service Guide (English only) for details.

●If the screen is blank, plug the monitor into a different video port on the computer if one is available. Or, change out the monitor with a monitor that you know is functioning properly.
