Performance Problems

If the Notebook Pauses or Runs Sluggishly

■This may be normal Windows behavior. Background processing can affect response time.

■Certain background operations (such as a virus-scanning program) can affect performance.

■Press ctrl+alt+del and use Task Manager to see if an application is not responding.

■Restart the notebook by selecting Start > Turn Off Computer > Restart.

■Some file browsers respond slowly while processing graphics or waiting for broken network connections to time out.

■If the notebook hard drive frequently runs (as indicated by the hard drive light on the front of the notebook) while the notebook appears to be paused or running slowly, Windows is likely spending excess time writing to its swap file on the notebook hard disk. If this occurs frequently, consider installing additional memory.

■Check the amount of available free disk space. Delete temporary and unneeded files.
