Chapter 4. Working with EasyUpdate
This chapter provides information on working with update packages, using the
EasyUpdate program, and the Web upgrade for EasyUpdate.
About EasyUpdate
When you search for updates using EasyUpdate the request goes to a repository or
the Lenovo Help Center (depending on how EasyUpdate is configured). In
response, EasyUpdate provides a list of new candidate updates. EasyUpdate then
checks to determine which of the candidate updates are applicable to the hardware
and software on your computer and displays a list of applicable updates.
EasyUpdate will also display packages in order of severity that are related to other
packages. Once you select updates of interest, EasyUpdate downloads the updates
from the repository or from the Lenovo Help Center, and then provides an
installation method. If two or more packages are related, EasyUpdate downloads
and installs all packages.
Designed to help you keep your system up-to-date, EasyUpdate provides the
following functions:
v Get new updates
v Install deferred updates
v Schedule updates
Extras tab
As a feature of the EasyUpdate program, 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 fullest capacity.
EasyUpdate analyzes your system, and then recommends solutions that can be
used to enhance your system. Examples of what the Extras tab may recommend:
v Memory upgrades
v Printer recommendations
v Warranty recommendations
Working with update packages
An update package is made by bundling several files together. Updates packages
consist of a self-extracting installer program, an XML Descriptor file that defines
the update, and one or more National Language Support (NLS) translated readme
files. An update may also optionally include one or more NLS translated license
files and one or more external detection files. Applicable update packages must
match the triplet on the client system. Triplets are the combination of the machine
type, operating system, and language.
Note:
If you have multiple machine type/model numbers selected on the Update
Retriever main window, all packages common to the multiple systems that you
select on the Applicable Updates window will result in a check mark next to each
system. Clearing the check box for one system will clear the check boxes for all of
the systems.
