Original article:

If your script needs to know whether your computer has a battery, you can ask WMI. Here is a small function:

Function has-battery {
 
@ (Get-wmiobject win32_battery). Count-Ne 0

If (@ (get-wmiobject win32_battery). Count-Ne 0 ){

$ True

} Else {

$ False

}
}

Note the use of @ () which wraps the result into an array so you can check the number of batteries. Most systems have only one, but there are some systems with more.

 

 

Translation:

If yourCodeYou need to know if your machine has a battery.WMI. The following small function can implement this method:

Function has-battery {
 
@ (Get-wmiobject win32_battery). Count-Ne 0

If (@ (get-wmiobject win32_battery). Count-Ne 0 ){

$ True

} Else {

$ False

}
}

The idea is@()Put the results in a sequence so that multiple batteries can be retrieved. Most systems only have one, but some systems also have multiple batteries.
