Hi

You can go to http://www-307.ibm.com/pc/support/site.wss/MIGR-67131.html. It looks like you forced to upgrade your system to Windows 7 since its only good for XP and Vista in terms of driver. What you cna do is try the vusta driver here and see if it will work for you. Thanks

Base System Device drivers are usually installed by what the manufacturer calls "Chipset" drivers. If you are running Windows XP, there is an Intel Chipset driver available at the Lenovo Support Page for your model. If you are running an Operating System other than Windows XP, I would go to the above page and compare the drivers listed there with what you are seeing in Device Manager. Install the ones that are missing. Hope this helps!
