If you are having problems with the computer, try the appropriate solutions as described in the previous sections and summarized below to try to isolate the exact problem before calling for technical support. ● Check the power LED on the front of the computer to see if it is flashing and 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, replace the monitor with a monitor that you know is functioning properly. ● If you are working on a network: ◦ Use a different network cable to connect your computer to the network. ◦ Connect a different computer with a different cable to the network. If your problem is not resolved, the network jack on your computer or the network wall jack might be faulty. ● If you recently added new hardware, remove the hardware. ● If you recently installed new software, uninstall the software. ● Boot the computer to Safe Mode to see if it will boot without all of the drivers loaded. To boot to Safe Mode: 1. Restart the computer. 2. Press and hold the F8 key before the operating system starts to display the Advanced Boot Options screen. 3.
