Attention: If you need updated device drivers, 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 102.

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 62.

•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 59.

•Set the USB 3.0 Mode as Disabled from the ThinkPad Setup menu.

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. For detailed information about temporarily or permanently changing the startup device sequence, see “Startup menu” on page 96.

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.
