Visit the Lenovo Support Web site and type the serial number for your computer to look up warranty information. Lenovo preinstalled operating system and software What is the Lenovo preinstalled operating system? Some Lenovo computers come with copies of the operating system installed at factory. Lenovo provides computers with preinstalled operating system for your convenience. If you purchased such a computer, you can use your computer out of the box and do not need to install a separate operating system. What is Lenovo preinstalled software? This is software (developed by Lenovo or other software vendors) installed and licensed at factory for your convenience. The license for some preinstalled software may be for trial versions. When the trial period expires, you may need to purchase a license if you want to continue to use the software. Note: If a license agreement is displayed when you first start the software, read the agreement carefully. If you don’t accept the terms of the agreement, do not use the software. When I purchased my computer, it included a copy of Windows. How can I determine whether the copy of Windows is preinstalled by Lenovo? On the outside of the sales package of your computer, you should find a label containing configuration information for your computer. Check the printed string next to OS. If it contains Windows or WIN, the copy of Windows was preinstalled by Lenovo. 18 Chapter 4. Troubleshooting What is the Recovery Partition? If your computer is preinstalled with any version of Windows 10, the storage device of your computer contains a Recovery Partition. This partition contains the image file of the preinstalled Windows operating system. In cases of system failure, you can use the Lenovo OneKey Recovery System or the Windows Reset feature to restore the operating system to its factory status. Note: The Recovery Partition is not assigned a drive letter and cannot be accessed through Windows File Explorer. I uninstalled a preinstalled software, but there is no significant increase in the free drive space. The copy of Windows running on your computer may be Compact-enabled. For computers with Compact-enabled Windows, the majority of files needed for preinstalled software are installed on the Recovery Partition and won’t be deleted through normal uninstallation. What happens if I attempt to delete or modify the Recovery Partition? Attention: Do not delete or modify the Recovery Partition on a Compact-enabled computer. If the Recovery Partition is deleted or modified, you may not be able to restore Windows to the factory status. For computer models on which Compact is enabled, deleting the Recovery Partition may cause Windows to fail to start. How can I determine whether the Windows running on my computer is Compact enabled? Compact technology is normally enabled on copies of Windows 10 Update running on SSD (or eMMC) -only computer models. To check your computer, 1 Right-click the Start button in the lower-left corner and select Disk Management. 2 The Disk Management program starts. If Compact is labeled on the Windows partition, Compact is enabled on your copy of Windows. Where can I find drivers for the various hardware devices of my computer? If your computer is preinstalled with a Windows operating system, first check the installation program on the C partition of your hard disk. If you cannot find the drivers for all the hardware devices that you need there, download the drivers from the Lenovo consumer support website. Note: The Lenovo support Web site contains the latest drivers. Lenovo OneKey Recovery System Where are the recovery discs? Your computer did not come with recovery discs. Use the Lenovo OneKey Recovery System if you need to restore the system to its factory status. What can I do if the back-up process fails? If you can start the backup but it fails during the back-up process, try the following steps: 1 Close all open programs, and then restart the back-up process. 2 Check to see if the destination media is damaged. Select another path and then try again. 19 Chapter 4. Troubleshooting When do I need to restore the system to its factory status? Use this feature when the operating system fails to start up. If there is critical data on the system partition, back it up before starting recovery. Is the Lenovo OneKey Recovery System preinstalled on all Lenovo notebook computers?
