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 96.

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 recovery

media” on page 62.

• 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 55.

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, 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 ThinkPad Setup program. For detailed information on how to temporarily or
permanently change the startup device sequence, see “Startup menu” on page 89.

It is important to create a rescue medium and a set of recovery media as early as possible and store them
in a safe place for future use.
