I've got a class that pulls model information (hardware info) for a local machine code is like so:
Imports System.Management
Public Class clsWMI
Private objOS As ManagementObjectSearcher
Private objCS As ManagementObjectSearcher
Private objMgmt As ManagementObject
Private m_strComputerName As String
Private m_strManufacturer As String
Private m_StrModel As String
Private m_strOSName As String
Private m_strOSVersion As String
Private m_strSystemType As String
Private m_strTPM As String
Private m_strWindowsDir As String
Public Sub New()
objOS = New ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem")
objCS = New ManagementObjectSearcher("SELECT * FROM Win32_ComputerSystem")
For Each objMgmt In objOS.Get
m_strOSName = objMgmt("name").ToString()
m_strOSVersion = objMgmt("version").ToString()
m_strComputerName = objMgmt("csname").ToString()
m_strWindowsDir = objMgmt("windowsdirectory").ToString()
Next
For Each objMgmt In objCS.Get
m_strManufacturer = objMgmt("manufacturer").ToString()
m_StrModel = objMgmt("model").ToString()
m_strSystemType = objMgmt("systemtype").ToString
m_strTPM = objMgmt("totalphysicalmemory").ToString()
Next
End Sub
Public ReadOnly Property ComputerName()
Get
ComputerName = m_strComputerName
End Get
End Property
Public ReadOnly Property Manufacturer()
Get
Manufacturer = m_strManufacturer
End Get
End Property
Public ReadOnly Property Model()
Get
Model = m_StrModel
End Get
End Property
Public ReadOnly Property OsName()
Get
OsName = m_strOSName
End Get
End Property
Public ReadOnly Property OSVersion()
Get
OSVersion = m_strOSVersion
End Get
End Property
Public ReadOnly Property SystemType()
Get
SystemType = m_strSystemType
End Get
End Property
Public ReadOnly Property TotalPhysicalMemory()
Get
TotalPhysicalMemory = m_strTPM
End Get
End Property
Public ReadOnly Property WindowsDirectory()
Get
WindowsDirectory = m_strWindowsDir
End Get
End Property
End Class
Any possibility to get a service tag from WMI ? From the client side form I display values like so:
Dim objWMI As New clsWMI()
With objWMI
Debug.WriteLine("Computer Name = " & .ComputerName)
Me.Label1.Text = "Name: " & .ComputerName
Debug.WriteLine("Computer Manufacturer = " & .Manufacturer)
Me.Label2.Text = "Manufacturer: " & .Manufacturer
Debug.WriteLine("Computer Model = " & .Model)
Me.Label3.Text = "Model: " & .Model
Debug.WriteLine("OS Name = " & .OsName)
Me.Label4.Text = "OS Name: " & .OsName
Debug.WriteLine("OS Version = " & .OSVersion)
Me.Label5.Text = "OS VERSION: " & .OSVersion
Debug.WriteLine("System Type = " & .SystemType)
Me.Label6.Text = "System type = " & .SystemType
Debug.WriteLine("Total Physical Memory = " & .TotalPhysicalMemory)
Me.Label7.Text = "Memory: " & .TotalPhysicalMemory
Debug.WriteLine("Windows Directory = " & .WindowsDirectory)
Me.Label8.Text = "Win Directory: " & .WindowsDirectory
End With
Entering the Service Tag in the BIOS setup programPress F2 when the Dell logo is displayed to enter the BIOS setup program. Navigate to the Main tab and enter the Service Tag in the Service Tag Input field.
I think you need to get the serial number from the BIOS like this:
Select SerialNumber From Win32_BIOS
On Dell's I believe this corresponds to the service tag
Here is some C# code that should get it
Here im getting from Win32_ComputerSystem but if you desire you can easly convert it to run againt Win32_Bios
void GetComputerSystem()
{
// http://msdn.microsoft.com/en-us/library/aa394102(VS.85).aspx
ManagementObjectCollection oReturnCollection;
try
{
ObjectQuery query = new ObjectQuery("Select UserName,Name,Manufacturer,Model from Win32_ComputerSystem");
ManagementObjectSearcher oSearcher = new ManagementObjectSearcher(gManager, query);
oReturnCollection = oSearcher.Get();
oSearcher.Dispose();
}
catch
{
gHasError = true;
return;
}
//loop through found drives and write out info
foreach (ManagementObject oReturn in oReturnCollection)
{
// Disk name
object oLoggedInUser = oReturn["UserName"];
if (oLoggedInUser == null)
gOSInfo.UserName = "None";
else
gOSInfo.UserName = (string)oLoggedInUser;
string Manufacturer = (string)oReturn["Manufacturer"];
string Model = (string)oReturn["Model"];
}
}
}
I wrote a program the recovers the Dell Service Tag, Express Code and links to the Driver and Warranty information. You can find the C# code at
