Performance problems

For best performance with Windows XP, your notebook should have at least 128 MB of
memory (RAM).
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 to see if an application is not responding.
• Restart the notebook.
• Some file browsers respond slowly while processing graphics or waiting for broken
network connections to time out.
• If the notebook's hard disk 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'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 notebook stops responding
• Press Ctrl+Alt+Del to end the application that is not responding.
