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 120.
