For starters, you are attempting to ping multiple computers - you use $CPName, which contains the contents of your text file. You do the same thing in a couple of places. You need to enumerate those and use just one computer name at a time. However, right now this is not very well written, the way you have nested all of the functions. It may be a little difficult to fix, the way this is currently written.

I see what you are trying to do, let me see if I can get your stuff in a close to working state.

#PowerShell Script - Get-MyLastBootReport.ps1
Param([String]$ComputerName)

Foreach ($Computer in $ComputerName)
{
if (Test-Connection -ComputerName $Computer -Count 1 -Quiet)
{
try {
$wmi = Get-WMIObject -ComputerName $Computer -Class Win32_ComputerSystem -Filter {Address -eq $Computer} -ErrorAction Stop
New-Object -TypeName PSObject -Property @{Computer=$Computer;Active=$True;LastBoot=$wmi.ConvertToDateTime($wmi.LastBootTime)}
}
catch { New-Object -TypeName PSObject -Property @{Computer=$Computer;Active=$True;LastBoot="UNKNOWN"} }
}
else
{
New-Object -TypeName PSObject -Property @{Computer=$Computer;Active=$False;LastBoot="NA"}
}
}
The way you would use it is to call the file and get the field from the CSV that has the computer name
\path\to\ps1\file\Get-MyLastBootReport.ps1 -ComputerName (Import-Csv -Path FILENAME.CSV | Select -ExpandProperty CName) | Export-Csv -Path \path\to\csv\lastbootreport.csv -NoTypeInformation

Hope that help and keep in mind that this is untested ad-hoc stuff.
