replacing i8042prt.sys and kbdclass.sys drivers

filups21 · 24 Dec 2009

I upgraded my dell studio 1535 from Vista 64 bit to 7 professional 64-bit and now have problems with the keyboard (It's usually recognized, but keystrokes are often not recorded. Sometimes it doesn't work at all). USB devices work fine. I have my Vista OS under c:\Windows.old so I would like to replace the 7 keyboard drivers (i8042prt.sys and kbdclass.sys) with the Vista drivers of the same names that are in c:\window.old\windows\system32\drivers Will this cause any problems? If not, how would I go about doing this?

Hi Filups21, Welcome to SF,

Scroll not working for Dell Studio 1535 on Windows 7 ultimate__Is there a patch of driver to fix this?

There it give a link to download an update http://ftp.us.dell.com/input/R227995.exe

Make sure you create a restore point before updating in case if something messes up could you restore it back.
