    My laptop recently developed a problem where the keyboard does not work within the Windows OS (Vista 64) but it works just fine outside the OS. For example, I can scroll the boot up menu just fine, and it takes alpha-numeric keys upon the OS install process. But once Windows boots, I am hosed. The touch pad does not work either. Here is what I have done so far:
    - USB Keyboard and mouse work just fine
    - Uninstalled/re-installed PS/2 standard keyboard driver- No luck
    - Device Mgr says that driver and hardware are just fine
    - Searches for new driver says existing one is the right one
    - Tried to copy the i8042prt.sys from another laptop and replace (different dates on the files)
    - Was not able to do so... I don't have the Sys Admin access to my own personal laptop, for some reason
    - Device Mgr does not recognize the touchpad driver
    - Re-loaded Vista three times... erased all partitions before re-install- No luck
    - Opened up laptop and checked keyboard connection... no problems there. Key board still works outside Win OS
    - Called Dell Tech Support- The guy tried to charge me $59.99 to do all the same things I had already done
    This problem happened to me after I opened an email and was replying to it. The keyboard just stopped working. However, I was able to re-boot and get back the functionality... for about a day. Then next re-boot, the problem has been permanent.
    Anyone have some thoughts?

    Well, I was able to solve the problem myself. I just replaced the touchpad hardware by replcing the palm-rest assembly and, voila, both the keyboard and touchpad started working! I got a brand new palm rest assembly online for about $38 including shipping. I am still a bit miffed why the keyboard was rendered inoperable when only the touchpad was faulty. But, who cares, it works now. I would be interested to hear if anyone else had this same problem and if this solved the problem.
