1. Turn on your computer. 2. Go to the C:\SWTOOLS directory. 3. Open the DRIVERS folder. Within the DRIVERS folder are 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. 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 33. • Use recovery media if all other methods of recovery have failed and you need to restore the hard disk drive or hybrid drive to the factory default settings. See "Creating and using a recovery media" on page 31. • Change the USB 3.0 Mode to be Disabled from the ThinkPad Setup menu. See "Creating and using a rescue medium" on page 33. 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 or 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 ensure that your rescue device is set as the first boot device in the startup device sequence in the ThinkPad Setup program. 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. Recovery overview for the Windows 8.1 operating system This section provides information about the recovery solutions for the Windows 8.1 operating systems. A Windows recovery image is preinstalled in the recovery partition on your computer. The Windows recovery image enables you to refresh your computer, or reset your computer to the factory default settings. You can create recovery media as backups or replacement for the Windows recovery image. With the recovery media, you can troubleshoot and fix the problems on your computer even if you cannot start the Windows 8.1 operating system. It is recommended that you create recovery media as early as possible. For more information, see "Creating and using recovery media" on page 37. Refreshing your computer If your computer does not perform well and the problem might be caused by a recently installed program, you can refresh your computer without losing your personal files or changing your settings.
