Recovering or installing device drivers

Before you can recover or install device drivers, your operating system must be installed on your computer. Make sure that you have the documentation and software media for the device.

Device drivers for factory-installed devices are located on the computer hard disk (usually drive C) in the SWTOOLS\drivers folder. Other device drivers are on the software media that come with individual devices.

The latest device drivers for factory-installed devices are also available on the

World Wide Web at http://www.lenovo.com/support/.

To reinstall a device driver for a factory-installed device, do the following:

1.Start your computer and operating system.

2.Use Windows Explorer or My Computer to display the directory structure of your hard disk.

3.Open the C:\SWTOOLS folder.

4.Open the DRIVERS folder. Within the DRIVERS folder are several subfolders that are named for various devices that are installed in your computer (for example, AUDIO or VIDEO).

5.Open the appropriate device subfolder.

6.Use one of the following methods to reinstall the device driver:

v In the device subfolder, look for a README. TEXT or other file with the

.TXT extension. This file might be named after the operating system, such as WIN98.TXT. The text file has information on how to reinstall that device driver.

vIf the device subfolder contains a file with an .INF extension, you can use the Add New Hardware program (located in the Windows Control Panel) to reinstall the device driver. Not all device drivers can be reinstalled using this program. In the Add New Hardware program, when prompted for the device driver that you want to install, click Have Disk and Browse. Then select the appropriate device driver file from the device subfolder.

vIn the device subfolder, look for a SETUP.EXE file. Double-click SETUP.EXE and follow the instructions on the screen.
