Installing or reinstalling device drivers

Before installing or reinstalling device drivers, make sure that you have a preinstalled operating system and
the documentation and software media for the device.
Device drivers for factory-installed devices are located on the computer hard disk drive (usually drive C:)
in the SWTOOLS\DRIVERS subdirectory. The latest device drivers for factory-installed devices are also
available at http://www.lenovo.com/support. Other device drivers are on the software media that come
with individual devices.
To install or reinstall the device driver for a factory-installed device, do the following:
1. Turn on the computer.
2. Use Windows Explorer or My Computer to display the directory structure of your hard disk drive.
3. Go to the C:\SWTOOLS directory.
4. Open the DRIVERS folder. Within the DRIVERS folder, there are several subfolders named for various
devices installed in your computer, such as AUDIO or VIDEO.
5. Open the appropriate device subfolder.
6. Do one of the following:
• In the device subfolder, look for a SETUP.exe file. Double-click the file and follow the instructions on
the screen to complete the installation.
• In the device subfolder, look for a README.txt file or a file with the .txt extension. This file might be
named after the operating system, such as WIN98.txt. The TXT file contains information about how to
install the device driver. Follow the instructions to complete the installation.
• If the device subfolder contains a file with the .inf extension and you want to install the device
driver using the INF file, refer to your Windows Help and Support information system for detailed
information about how to install the device driver.
