I have the W500. You have to use DH's modder tool and get the catalyst from here DriverHeavenDownloads.net - Fast n Furious then use the modder tool here Mobility Modder - DriverHeaven.net Follow the steps given here. Remember to switch disable the UAC from MSCONFIG before you mod the driver or it won't work properly. Also after you have modded the driver, go into BIOS and switch display to DISCRETE. Once the computer start up you will see a driver being located and installed in the system tray. Ignore what is happening there and do not restart when prompted by Windows. Instead go into C:\ATI\SUPPORT\..... where your modded driver folder should be located and do a setup. It will tell you that windows does not recognise this driver which is a side effect of the modification. Install the driver and reboot. You should also download the switchable graphics driver from Lenovo's website here Lenovo Support & downloads - Drivers and software - ThinkPad T500, W500 and reinstall that if you want that option to work properly. Shut down and start back up, go into BIOS, restore your Display defaults and save and exit. Hopefully everything should be in order. You should see the ATI icon in your system tray, and if you right click on the desktop you should be able to avail of the switchablegarphics feature in your W500. Good luck!
