Advanced Settings; Exiting From The Setup Utility Program - Lenovo ThinkCentre A57e User Manual

Advanced settings

On some computer models, the Advanced settings menu includes a setting to
enable or disable HyperThreading. This feature works only with
HyperThreading-aware operating systems, such as Microsoft 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.

Exiting from the Setup Utility program

After you finish viewing or changing settings, press Esc to return to the Setup
Utility program menu (you might have to press Esc several times). If you want to
save the new settings, select Exit → Save Changes and Exit. Otherwise, your
changes will not be saved.
