Enable Dell TPM Chip with Powershell

Here’s some Powershell code I used to enable the Dell TPM chip with Dell Command.  The Get-Laptop function was provided by https://blogs.technet.microsoft.com/heyscriptingguy/2010/05/15/hey-scripting-guy-weekend-scripter-how-can-i-use-wmi-to-detect-laptops/

The –% option (that’s dash-dash%) basically just says “Powershell, just pass these arguments along and don’t try to interpret them”.  This functionality requires Powershell v3 or later.

Probably would have been better to use Start-Process and check if the exitcode is not zero.  Note to use Dell Command to turn on the TPM chip you need to set a BIOS password and for 64-bit systems you need to use the 64-bit version of CCTK.

Function Get-Laptop
[string]$computer = "localhost"
$isLaptop = $false
if(Get-WmiObject -Class win32_systemenclosure -ComputerName $computer |
Where-Object { $_.chassistypes -eq 9 -or $_.chassistypes -eq 10 `
-or $_.chassistypes -eq 14})
{ $isLaptop = $true }
if(Get-WmiObject -Class win32_battery -ComputerName $computer)
{ $isLaptop = $true }
} # end function Get-Laptop

If(get-Laptop) {

.\cctk.exe –% –setuppwd=secretpassword
.\cctk.exe –% –tpm=on –valsetuppwd=secretpassword
.\cctk.exe –% –tpmactivation=activate –valsetuppwd=secretpassword
.\cctk.exe –% –tpm
.\cctk.exe –% –tpmactivation
.\MbamClientSetup.exe –% /q /acceptEula=Yes

else { # do nothing }
