go to the manufacturer's website..... type in the MODEL number of the computer in the SUPPORT /driver D/L area
9) ALL computers that come with an OS in tact that you have to "SETUP"  on startup that installed "windows" to begin with has the OS already on the computer itself.... including all drivers.....you just have to know where to "look" for them with the browse command

IBM made the "thinkpad" with various processors and configurations....

Go to This site http://www-307.ibm.com/pc/support/site.wss/homeLenovo.do?country=us then CLICK ON  "AUTO DETECT THIS SYSTEM"

From there you should be able to get the proper drivers....

IF the US drivers do not work you need to use the drivers and OS from the area the PC was manufactured in and you should be able to change the country selection to get the available drivers

IF you did not have the "original" disc's to the system... how did you "reformat" the hard drive to begin with? Did you use a different OS other then what was originally installed? That too could be causing the problem.
