keyboard not working toshiba satellite a505 s6012 with windows 7 64bit

[Haymore]

Trying to use laptop keyboard
Load Ubuntu from a usb flash drive and keyboard works fine
Keyboard arrow keys work fine for select boot drive in the bios setup
If I start safe mode keyboard does not work
Start reinstall of windows 7 with Microsoft install dvd disk and keyboard quits working shortly

Use usb keyboard and all is well - but it is a laptop and I do not want to lug an extra keyboard around

Suggestions?

Have you scanned for Viruses or Malware?

Which Antivirus and Malware programs do you use?

Have you tried a Clean Boot?

Same result - no laptop keyboard after clean boot per How to perform a clean boot in Windows
when I plug in the usb keyboard after checking on the laptop KB it works fine.
