Reinstalling software programs
If a software program you installed on your computer is not working correctly, you might need to remove
and reinstall it. Reinstalling overwrites the existing programs files and usually fixes any problems that
you might have had with that program.
To remove a program in your system, see Microsoft Windows help system for detailed information.
To reinstall the program, do one of the following:
Note: The method of reinstalling a program varies from program to program. Refer to the documentation
provided with the program to see if your program has special installation instructions.
• To reinstall most commercially available programs in your system, see Microsoft Windows help system
for more information.
• To reinstall selected application programs that came preinstalled from Lenovo, do the following:
1. Turn on the computer.
2. Use Windows Explorer or Computer to display the directory structure of your hard disk drive.
3. Go to the C:\SWTOOLS directory.
4. Open the APPS folder. Within the APPS folder, there are several subfolders named for various
applications installed in your computer.
5. Open the appropriate application subfolder.
6. In the application subfolder, look for a SETUP.EXE file or other appropriate EXE files for setup.
Double-click the file and follow the instructions on the screen to complete the installation.
Reinstalling device drivers
To reinstall a device driver for an option you installed, refer to the documentation that comes with the option.
When you reinstall device drivers, you are changing the current configuration of your computer. Reinstall
device drivers only when it is necessary to correct a problem with your computer.
For more information about reinstalling device drivers that came with your computer, see "Reinstalling
preinstalled applications and device drivers" on page 41.

If you are unable to access the Rescue and Recovery workspace or the Windows environment, do one
of the following:
• Use a rescue medium to start the Rescue and Recovery workspace. See "Creating and using a rescue
medium" on page 40.
• Use recovery media if all other methods of recovery have failed and you need to restore the hard disk
drive to the factory default settings. See "Creating and using recovery media" on page 37.
