Get Lenovo Warranty Information with PowerShell

As many of you have probably already seen, some time ago I released the Dell Warranty Status Tool 2.0 as a console extension for ConfigMgr 2012. I’ve received tweets and comments from the community asking for the same kind of console extension for Lenovo and HP. Unfortunately Lenovo doesn’t provide a web service like Dell does (at least to my knowledge), so I’ve been struggling with what approach to use that will be the most stable one. I’ve come up with a basic script that can parse through the web page of Lenovo’s warranty information for a particular system, but I’d like to reach out to the community for a helping hand as I’m not sure if this is the best solution available. Enough talking, here’s the script:

Script

<#
.SYNOPSIS
    Get warranty information for a Lenovo system
.DESCRIPTION
    This script will parse through the warranty information webpage for a particular Lenovo system. Required information is the model and serialnumber of the system.
.PARAMETER Model
    Specify the model information
.PARAMETER SerialNumber
    Specify the SerialNumber
.PARAMETER ShowProgress
    Show a progressbar displaying the current operation
.EXAMPLE
    .\Get-LenovoWarrantyInformation.ps1 -Model "XXXXXXXXXX" -SerialNumber "XXXXXXXX" -ShowProgress
    Get warranty information for a Lenovo system with Model 'XXXXXXXXXX' and SerialNumber 'XXXXXXXX' and show the progress:

Using the script

As of right now, the script is basically just for running in a PowerShell console where you manually enter the Model and SerialNumber information of a Lenovo system. My intention is of course to extend this as a console extension for ConfigMgr later.
1. Save the script above as Get-LenovoWarrantyInformation.ps1 to e.g. C:\Scripts.
2. Open a PowerShell console and browse to C:\Scripts.
3. Run the following command:

.\Get-LenovoWarrantyInformation.ps1 -Model 20AR003SMN -SerialNumber PF01GACH -ShowProgress

That’s the output of the script as of right now, what do you guys think? Could you give it a try and let me know in the comments? I’m very much interested if any of you have made similar scripts but used another method. I’m not very pleased regarding the parsing of the HTML, but hey, you learn as you go.
Thank in advance!
