.SYNOPSIS This function gets power settings for local or remote computer(s). .DESCRIPTION This function gets power setting for local or remote computer(s). You can filter the results using the parameters SettingName, PlanName, ActivePlanOnly, and SettingType. .PARAMETER ComputerName This parameter specifies the ComputerName for the computer you want to get power setting from. Default value is $ENV:COMPUTERNAME. .PARAMETER PlanName This parameter specifies the plan name of the plan you want to get power settings for. Common plan names include "HP Optmized" and "Balanced". The function will grab all settings for all plans if no plan name is give. User inputted wildcards are not permitted, but the value provided will have wildcards on both sides added to it. .PARAMETER ActivePlanName This switch parameter will filter the power settings so that only the setting for currently active power plan are returned. .PARAMETER SettingName This parameter specifies the name of the power setting you want to grab. Wildcards are accepted. By default, all settings are returned. .PARAMETER SettingType This parameter specifies the power type for the setting, options include DC (on battery) or AC (wall power) power. .EXAMPLE PS C:\> Get-PowerSetting -ActivePlanOnly -SettingName *timeout* -SettingType AC Plan Name: HP Optimized (recommended) ComputerName Active Type SettingName SettingValue Range ------------ ------ ---- ----------- ------------ ----- TEST-MACHINE1-D True AC Secondary NVMe Idle Timeout 2000 milliseconds {0, 60000} TEST-MACHINE1-D True AC Primary NVMe Idle Timeout 200 milliseconds {0, 60000} TEST-MACHINE1-D True AC System unattended sleep timeout 3600 Seconds {0, 4294967295} TEST-MACHINE1-D True AC Hub Selective Suspend Timeout 50 Millisecond {0, 100000} TEST-MACHINE1-D True AC Execution Required power request timeout 4294967295 Seconds {0, 4294967295} TEST-MACHINE1-D True AC IO coalescing timeout 0 Milliseconds {0, 4294967295} TEST-MACHINE1-D True AC Console lock display off timeout 1800 Seconds {0, 4294967295} TEST-MACHINE1-D True AC Non-sensor Input Presence Timeout 240 Seconds {0, 4294967295} In this example we get all power settings that are on the Active power plan that have "timeout" in their name and associated with AC power type. .EXAMPLE PS C:\> Get-PowerSetting -ComputerName TEST-LAPTOP02-L,TEST-MACHINE1-D -ActivePlanOnly -SettingType AC -SettingName "Console lock display off timeout" Plan Name: Balanced ComputerName Active Type SettingName SettingValue Range ------------ ------ ---- ----------- ------------ ----- TEST-LAPTOP02-L True AC Console lock display off timeout 60 Seconds {0, 4294967295} Plan Name: HP Optimized (recommended) ComputerName Active Type SettingName SettingValue Range ------------ ------ ---- ----------- ------------ ----- TEST-MACHINE1-D True AC Console lock display off timeout 1800 Seconds {0, 4294967295} In this example we get the power setting "Console lock display off timeout" from two computers for the active power plan on AC power. Here we can see TEST-MACHINE1-D has a 1800 seconds (30 minutes) time out for this second where TEST-LAPTOP02-L has 60 second timeout. This setting controls how fast the ocmputer goest to sleep after a user locks there computer. The default of 60 seconds is usually too low. .EXAMPLE PS C:\> Get-PowerSetting -ComputerName TEST-LAPTOP02-L -ActivePlanOnly -SettingType AC -SettingName "Console lock display off timeout" Plan Name: Balanced ComputerName Active Type SettingName SettingValue Range ------------ ------ ---- ----------- ------------ ----- TEST-LAPTOP02-L True AC Console lock display off timeout 60 Seconds {0, 4294967295} PS C:\> Get-PowerSetting -ComputerName TEST-LAPTOP02-L -ActivePlanOnly -SettingType AC -SettingName "Console lock display off timeout" | Set-PowerSetting -IndexValue 1800 PS C:\> Get-PowerSetting -ComputerName TEST-LAPTOP02-L -ActivePlanOnly -SettingType AC -SettingName "Console lock display off timeout" Plan Name: Balanced ComputerName Active Type SettingName SettingValue Range ------------ ------ ---- ----------- ------------ ----- TEST-LAPTOP02-L True AC Console lock display off timeout 1800 Seconds {0, 4294967295} The first command gets the "Console lock display off timeout" power setting for TEST-LAPTOP02-L and outputs it to the console. We se it is set to 60 seconds. The second command runs the same command but then pipes it to Set-PowerSetting and provides the value 1800 to the parameter IndexValue. This will set that setting to 1800 seconds (30 minutes). The last command run the first command again to confirm that the setting was udpated to the new vale, and here we can see that it was. This particular setting's default value of 60 seconds is pretty low. It will put the computer asleep after 60 seconds a user locking their computer. If the user is just getting up to for a minutes it can frustrating to come back and have to wake the computer. .INPUTS [string] ComputerName .OUTPUTS [spz.Utility.PowerSetting] .NOTES The default grouping of the output is by plan name. All parameters have built-in tab completion, besides ComputerName.
