Client Management Suite

Can i change the time period of sleep mode on systems with altiris solution?

Yes, you can use "Power Scheme" solution

1. Rollout "Power Scheme" plug-in on managed Windows OS
2. Execute Power Scheme Inventory and set required Power Scheme settings via task as well.
3. Check report data about power scheme on managed endpoints.
4. Power Scheme solution doesn't required license, therefore you can use it on any amount of managed Windows endpoints.

Also you can try to modify power scheme settings on client PC, using only a "Run Script" task without "Power Scheme" solution usage.

• Create "Run Script" task ⇒ set appropriate cmd line to change a power scheme on managed windows clients and schedule it to run on clients.
