1. When new devices are claimed and licensed.
2. On-demand from the System Update page by clicking on the Check for updates link. 

1. Remote Deployment: Available updates can be deployed remotely at any time to one or more devices, as well as to groups of devices.
2. User Control: End users can accept or deny updates requiring a reboot based on the deferral configuration set in LDM.
3. Tracking: All System Update installations are tracked through the System Update Status Report.

This feature requires either a Pro or a Premium license and a special add-in service on the device to check for updates from the Lenovo repository. Most Lenovo devices are automatically preloaded with this service but if it was removed or your custom preload does not include it, LDM can automatically install it during provisioning. To enable automatic validation for the service, go to Policy Management/Organization Settings/Features/System Update Preferences

Troubleshooting

Using System Update

Schedule all Available Updates button

1. Deploy Now
1. Select this option to deploy the updates immediately.
2. Click Next.
1. A notification window will appear, displaying a list of updates affected by the operation.
2. Detailed information for each update is presented as it appears on the System Update page.
3. Expanding the accordions reveals the list of devices to which each update will be applied.
3. Click Submit. This operation will take some minutes.
2. Schedule Deployment
1. Select a specific Date and Time for deploying the update. 
1. Note: If devices are in different time zones, ensure the selected date and time is in the future for all devices. For example, if you have a device in India and another in Brazil, the India time zone is ahead of Brazil by several hours. To accommodate this, you must select a date and time that is several hours ahead of Brazil's local time, as this will be the earliest allowable time for deployment across all devices.
2. However, to prevent users from being blocked by a long-running operation, a minimum limit of 24 hours ahead has been set to ensure compatibility across all time zones
2. Click Next. 
1. An information window appears showing the selected date and time, and information about the updates programmed to be deployed.
3. Click Submit.

The Schedule All Available Updates will remain disabled for 5 minutes to avoid overlapping operations.
