Need Help With Powershell Script for PC Uptime and Reboot

[MarshMan0331]

The script below will tell me the uptime on PC's. I want to add the language that says if Uptime is greater than X amount of days then it will send a reboot in 15 Mins. Any help would be appreciated.

 

# This PS script provides Uptime and Pingstatus for list of computers.
#######################################################################
$names = Get-Content "C:\Test\computers.txt"
@(
foreach ($name in $names)
{
if ( Test-Connection -ComputerName $name -Count 1 -ErrorAction SilentlyContinue )
{
$wmi = gwmi Win32_OperatingSystem -computer $name
$LBTime = $wmi.ConvertToDateTime($wmi.Lastbootuptime)
[TimeSpan]$uptime = New-TimeSpan $LBTime $(get-date)
Write-output "$name Uptime is $($uptime.days) Days"
Write-Host "$name Uptime is $($uptime.days) Days" -ForegroundColor Green
}
else {
Write-output "$name is not pinging"
Write-Host "$name is not pinging" -ForegroundColor Red
}
}
) | Out-file -FilePath "C:\Test\results1.csv"

if($uptime.days -gt 3){$wmi.Win32ShutdownTracker(300, 'provide a message for logged on users here.', 0, 2)}

This would reboot a machine, which is running for more than 3 days, after 5 minutes grace and also show a message to a logged on user.
