Power

The Power Policy page creates and maintains power policies and applies them to selected machine IDs. A power policy determines how a machine's power management options are configured. Power management options can be set for:

  • The display screen
  • The hard drive
  • Shut down, hibernate and stand by time periods
  • Low battery warnings

You can provide your customers a significant savings in power consumption and extend the battery life of laptops automatically by applying a Power Policy to all your managed machines. The same policy is applied to each user on a machine, whether they are logged in or not. A power policy is not defined by group ID, since the same power policies are applicable to multiple customers. A machine must have the Desktop Policy client installed using Install/Remove to display on this page.

Note: Certain machines may not support one or more power policy settings. Typical examples include virtual machines and terminal servers. Power policies settings, if applied to these machines, are skipped. The Power Status page identifies which machines do not support a specific power policy setting.

Predefined Power Policies

The following predefined power policies are provided by KDPM and cannot be changed. They are based on predefined power schemes in Windows XP. You can assign them just as you would any user-defined power policy. You should be aware that selecting a predefined power policy affects processor performance on XP machines.

Processor Performance Control Policies

Microprocessors employ different performance states:

  • High voltage/high frequency states for use when processor utilization is high.
  • Low voltage/low frequency states to conserve battery life.

To support these microprocessor performance states, Windows XP uses processor performance control policies. The power policy determines the processor control policy on the target machine.

Policy

Description

None

Highest performance state.

Adaptive

Performance state chosen according to demand.

Degrade

Lowest performance state + additional linear performance reduction as battery discharges.

Actions

This page provides you with the following actions:

Schedule - Click Schedule to display the Scheduler window, which is used throughout the VSA to schedule a task. Schedule a task once or periodically. Each type of recurrence—Once, Hourly, Daily, Weekly, Monthly, Yearly—displays additional options appropriate for that type of recurrence. Periodic scheduling includes setting start and end dates for the recurrence. Not all options are available for each task scheduled. Options can include:

  • Distribution Window - Reschedules the task to a randomly selected time no later than the number of periods specified, to spread network traffic and server loading.
  • Skip if offline - If checked and the machine is offline, skip and run the next scheduled period and time. If blank and the machine is offline, run the task as soon as the machine is online again.
  • Power up if offline - Windows only. If checked, powers up the machine if offline. Requires Wake-On-LAN or vPro and another managed system on the same LAN.
  • Exclude the following time range - If checked, specifies a date/time range to not perform the task.

Apply Now - Apply a selected policy to selected machine IDs.

Cancel - Cancel schedule options for selected machined IDs.

Edit - Add, edit or delete an existing power policy. When adding or editing a policy you can rename the policy. The policies you create apply to all groups. To create a new policy select <Create New Power Policy> from the policy drop-down list and click Edit. You can Share... the power policies you create with other users or user roles. Built-in power policies cannot be modified and are already shared with all users.

Check-in status

These icons indicate the agent check-in status of each managed machine:

Online but waiting for first audit to complete

Agent online

Agent online and user currently logged on. Icon displays a tool tip showing the logon name.

Agent online and user currently logged on, but user not active for 10 minutes

Agent is currently offline

Agent has never checked in

Agent is online but remote control has been disabled

The agent has been suspended

Select All/Unselect All

Click the Select All link to check all rows on the page. Click the Unselect All link to uncheck all rows on the page.

Machine.Group ID

The list of Machine.Group IDs displayed is based on the Machine ID / Group ID filter and the machine groups the user is authorized to see using System > User Security > Scopes.

Power Policy

The policy assigned to this machine ID.

Last Apply Time

The last time this policy was applied to this machine ID.

Skip if Machine Offline

If a checkmark displays and the machine is offline, skip and run the next scheduled period and time. If no checkmark displays, perform this task as soon as the machine connects after the scheduled time.

Next Apply Time

The next time this policy is scheduled to be applied. Overdue date/time stamps display as red text with yellow highlight.

Period

If recurring, displays the interval to wait before running the task again.
