I am not sure why but my laptop, Lenovo ThinkPad T420 is not updating any drivers, I ran the troubleshooting for hardware and that is what came up but it did not tell me what I need to do in order for it to update my drivers.  Is there a setting that I need to turn on or does anyone know how to get it to download my drivers?  I have Windows 7 SP 1 64 bit and I just got it two months ago, it was refurbished.  If anyone can help me I would really appreciate it.
