This chapter provides information on working with update packages, using System Update, and downloading
the Web upgrade for System Update.
About System Update
When you search for updates using System Update, the request goes to a repository or the Lenovo Help
Center, depending on how System Update is configured. In response, System Update provides a list of
new candidate updates. Then System Update verifies which of the candidate updates are applicable to the
hardware and software on your computer and displays a list of applicable updates. System Update will
also display update packages in order of severity that are related to other update packages. Once you
select updates of interest, System Update downloads the updates from the repository or the Lenovo Help
Center, and then provides an installation method. If two or more update packages are related, System
Update downloads and installs all update packages.
Designed to help you keep your system up-to-date, System Update provides the following functions:
• Get new updates
• Install deferred updates
• Schedule updates
Extras tab
As a feature of System Update, the Extras tab enables you to easily identify the applicable software,
hardware, and solution offerings to help you keep your entire system performing to its full capacity.
System Update analyzes your system, and then recommends solutions that can be used to enhance your
system performance. Examples of what the Extras tab may recommend include:
• Memory upgrades
• Printer recommendations
• Warranty recommendations
System Update billboard
In various panels of the System Update user interface, there is a live feed billboard image provided by
Lenovo for customer registration. If you click this image, the registration process will begin. If you register,
you will receive important information about your system from Lenovo. You can turn this live feed off by
clearing the value in the registry. For more information on configuring this setting with the registry, the ADM
file, or the start.reg file, see Chapter 3 “Configurations” on page 15.
Note: The registration function is available to users in United States only.
Working with update packages
An update package is made by bundling several files together. An updates package consists of a
self-extracting installer program, an XML descriptor file that defines the update, one or more NLS readme
files, any package license file, and any optional detection modules.
Applicable update packages must match the triplet of a client computer. A triplet is the combination of the
operating system, machine type (MT), and operating system language. An example of a triplet value is:
