Troubleshooting and Maintenance Troubleshooting Techniques • Press CTRL+ALT+DEL and use Task Manager to see if an application is not responding. • Restart the computer: click Start, Turn Off Computer (or Shut Down), Restart. • Some file browsers respond slowly while processing graphics or waiting for broken network connections to time out. • If the computer's hard disk drive frequently runs (as indicated by the hard drive light on the front of the computer) while the computer appears to be paused or running slowly, Windows is likely spending excess time writing to its swap file on the computer's hard disk. If this occurs frequently, consider installing additional memory. • Check the amount of available free disk space. Delete temporary and unneeded files. If the computer stops responding • Press CTRL+ALT+DEL and use Task Manager to end the application that is not responding. • Press the power button for at least 4 seconds to turn off and reset the computer. Then press the power button again to turn the computer back on. • If nothing happens, insert the tip of a ballpoint pen into the reset button on the bottom of the computer. Then press the power button to turn the computer back on. Port Replicator Problems If a connection isn't working • Check that AC power is connected to the port replicator, that the computer is fully docked, and that the port replicator lights are on. • Make sure the peripheral device has power connected and is turned on. • Make sure the device's cable is connected properly. • The LAN port works only if the computer has a built-in LAN port. • Try using the corresponding port on the computer while undocked. • Make sure the computer is fully inserted into the port replicator.
