根据BIOS信息修改主机名

Dell: 
Rename-Computer -NewName ("CNHZPD-" + (Get-WmiObject -class win32_Bios).SerialNumber.substring(0,7)) -Restart

Lenovo:
$parttern_ln="\b\D{2}\d{8}\b"
$parttern_tp="\b\w{7}\b"
$biosname = (Get-WmiObject -Class win32_Bios).serialnumber
$baseboardname = (Get-WmiObject -Class win32_BaseBoard).serialnumber
if ($biosname -match $parttern_ln) { Rename-Computer -NewName ("CNHZLN-" + $biosname.Substring(2,8)) -Restart }
elseif($baseboardname -match $parttern_ln) { Rename-Computer -NewName ("CNHZLN-" + $baseboardname.Substring(2,8)) -Restart }
elseif($biosname -match $parttern_tp) { Rename-Computer -NewName ("CNHZLN-" + $biosname) -Restart }
else {Write-Host "Sorry"}
