For a quick look, using device manager is fine, but you can really do magic using PowerShell. The goal is to find the Device ID(s) for the devices that are missing drivers. You can either just open device manager and look, or use PowerShell to find out which drivers are missing. Identify missing driversĪfter deploying a clean Windows image to the Lenovo ThinkPad T420 you need to find out if any drivers are missing. But you can use any deployment solution you prefer as long as it's automated. Deploy a clean Windows 7 or Windows 8 imageįor hardware testing I typically use a MDT 2012 Update 1 offline media which I deploy from a USB stick, because it allows me to lay down a clean Windows image in about 5 – 7 minutes (assuming SSD). Lenovo store these packages on the Microsoft System Center Configuration Manager (SCCM) and Microsoft Deployment Toolkit (MDT) Package Index page, but as of this writing (August 2013), no packages are available for the ThinkPad T420. Note 2: Lenovo has started to make deployment-ready packages for some of it's models (ThinkCentre M82, M92, M92p and ThinkPad Helix, X1 Carbon, L430, L530, X131e, T430, T430i, T430s, T430si, T530, T530i, W530, X230 Tablet, X230i Tablet, T430u, X230s, and T431s). Note 1: Lenovo does provide you with model specific guides on how to install a clean Windows 7 installation (see ) but I wanted to provide you with a generic guide, that works for any hardware or Windows operating system.
Download any needed driver applications and verify that they work on the machine.Identify if any driver applications are needed, hotkeys etc.Verify that the drivers work on the machine.Deploy a clean Windows 7 or Windows 8 image.As an example I'm certifying the good old ThinkPad T420 from Lenovo for Windows 7, but you can follow this method for any Lenovo model or Windows operating system. There are many techniques available to find drivers and certify a new hardware model.
