Using Dell™ PC Restore by Symantec
NOTE:
Dell PC Restore is not available in all countries.
Use Dell PC Restore by Symantec only as the last method to restore your operating system. PC Restore
restores your hard drive to the operating state it was in when you purchased the computer. Any programs or
files added since you received your computer
— including data files—are permanently deleted from the hard
drive. Data files include documents, spreadsheets, e-mail messages, digital photos, music files, and so on. If
possible, back up all data before using PC Restore.
NOTICE:
Using PC Restore permanently deletes all data on the hard drive and removes any applications or drivers
installed after you received your computer. If possible, back up the data before using PC Restore.
To use PC Restore:
1 Turn on the computer and watch the keyboard status lights.
