Reinstalling preinstalled programs
To reinstall selected programs, do the following:
1. Turn on your computer.
2. Go to the C:\SWTOOLS directory.
3. Open the APPS folder. The folder contains several subfolders named for the various preinstalled
applications.
4. Open the subfolder for the program you are reinstalling.
5. Double-click Setup, and then follow the on-screen steps to reinstall the program.
Reinstalling preinstalled device drivers
Attention: 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.
To reinstall a device driver for a factory-installed device, do the following:
1. Turn on your computer.
2. Go to the C:\SWTOOLS directory.
3. Open the DRIVERS folder. The folder contains several subfolders named for the various devices
installed in your computer (for example, AUDIO and VIDEO).
4. Open the subfolder for the device.
5. Reinstall the device driver by one of the following methods:
• In the subfolder for the device, look for a text file (a file with the extension .txt). The text file contains
information on how to reinstall that device driver.
• If the subfolder for the device contains a file of setup information (a file with the extension .inf), you
can use the Add New Hardware program (in the Windows Control Panel) to reinstall the device driver.
Not all device drivers can be reinstalled by use of this program. In the Add New Hardware program,
when prompted for the device driver you want to install, click Have Disk and Browse. Then select
the device driver file from the device subfolder.
• In the subfolder for the device, look for the executable file (a file with the extension .exe). Double-click
the file, and follow the instructions on the screen.
Attention: If you need updated device drivers for your computer, do not download them from the Windows
Update Web site. Obtain them from Lenovo. For more information, see "Making sure device drivers are
current" on page 88.

Solving recovery problems

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 112.
• Use recovery media if all other methods of recovery have failed and you need to restore the storage
devices to the factory default settings.
Note: If you are unable to access the Rescue and Recovery workspace or the Windows environment from a
rescue medium or recovery media, you might not have the rescue device (an internal hard disk drive,
solid-state drive, hybrid drive, a disc, a USB hard disk drive, or other external devices) set as the first boot
device in the startup device sequence. You must first make sure that your rescue device is set as the first
boot device in the startup device sequence in the Setup Utility program. See "Startup menu" on page 82 for
detailed information about temporarily or permanently changing the startup device sequence. For more
information about the Setup Utility program, see "Using the ThinkPad Setup program" on page 70.
