Software provided by Lenovo
The following software applications are provided by Lenovo to help you improve productivity and reduce the cost associated with maintaining your computer. Software provided with your computer may vary depending on your model. ThinkVantage Productivity Center The ThinkVantage Productivity Center program guides you to a host of information and tools to help you set up, understand, maintain, and enhance your computer.
ThinkVantage Rescue and Recovery
The ThinkVantage Rescue and Recovery program is a one button recovery and restore solution that includes a set of self recovery tools to help users diagnose, get help, and recover from system crashes quickly, even if the primary operating system will not start.
ThinkVantage Client Security Solution
This ThinkVantage Client Security Solution (CSS) is available on select Lenovo computers. It helps protect your information, including vital security information like passwords, encryption keys, and electronic credentials, while guarding against unauthorized user access to data.
ThinkVantage System Update
ThinkVantage System Update (TVSU) is a software application that helps you keep the software on your system up-to-date, by downloading and installing software packages (TVT applications, device drivers, BIOS flashes, and other third party applications). Some examples of software that you should keep updated are programs provided by Lenovo, such as the Rescue and Recovery program and the Productivity Center program.
System Migration Assistant
System Migration Assistant (SMA) is a software tool that enables system administrators and individual users to migrate a work environment from one computer to another.
Fingerprint Software
The integrated fingerprint reader provided on some keyboards enables you to enroll your fingerprint and associate it with your power-on password, hard disk drive password, and Windows password. As a result, fingerprint authentication can replace passwords and enable simple and secure user access. A fingerprint reader keyboard is available with select computers or can be purchased for computers that support this option.
PC Doctor for Windows, PC Doctor for Windows PE
The diagnostic programs are preinstalled from the factory on your hard disk drive. Two diagnostic programs are available to assist you in diagnosing hardware problems. PC-Doctor for Windows works through the Windows operating system to diagnose hardware problems and report operating-system-controlled settings that can cause hardware failures. The PC-Doctor for Windows PE diagnostic program is part of the Rescue and Recovery workspace. Use PC-Doctor for Windows PE if you are unable to start the Windows operating system or if PC-Doctor for Windows has not been successful in isolating a possible problem.
Advanced settings
On some computer models, the Advanced menu includes a setting to enable or disable HyperThreading. This feature works only with HyperThreading-aware operating systems, such as Windows Vista and Windows XP. The default setting for HyperThreading is Enabled. However, if you select Set Defaults and are using an operating system other than Windows Vista or Windows XP, your computer performance might be degraded. Therefore, you should always set HyperThreading to Disabled unless you are sure your operating system supports HyperThreading.
Using system programs
System programs are the basic layer of software built into your computer. They include the power-on self-test (POST), the basic input/output system (BIOS) code, and the Setup Utility program. POST is a set of tests and procedures that is performed each time you turn on your computer. BIOS is a layer of software that translates instructions from other layers of software into electrical signals that the computer hardware can execute. You can use the Setup Utility program to view and change the configuration and setup of your computer. Your computer system board has a module called electrically erasable programmable read-only memory (EEPROM, also referred to as flash memory). You can easily update POST, BIOS, and the Setup Utility program by starting your computer using a flash update diskette, a disc, or by running a special update program from your operating system.
Lenovo might make changes and enhancements to the POST/BIOS. When updates are released, they are available as downloadable files on the Lenovo Web site at http://www.lenovo.com. Instructions for using the POST/BIOS updates are available in a TXT file that is included with the update files. For most models, you can download either an update program to create a system-program-update (flash) diskette/disc or an update program that can be run from the operating system.
