I have had this problem for a few months. I have a toshiba satellite a45-s150 and I am using windows xp pro. When I first turn on the laptop I am able to input the hard disk password. After that my keyboard will only type a few keys...f - find, h - history, m - enter key, etc. I reistalled windows a few times, CLEAN installation, and since the keyboard doesn't work this was a problem. I kept pushing keys until I finally got the windows install started. The product key would not type so I went back to the languages menu and added dyvork and them removed dyvork and my keyboard let me type the product key...... but after windows was installed and loaded the keyboard still will not work, even if I go to control panel and REPEAT the steps i just mentioned. I finally downloaded a virtual keyboard called IMG My T-Touch. For whatever reason if I open this program my keyboard works perfectly FINE. But I only download the demo copy and now I have to open this program in safe mode for the keyboard to work. Otherwise every few letters I have to reopen T-Touch and it is very frustrating. Does anyone know what I need to do to fix this? I am pretty much ready to throw this laptop out the window.. Please help!At some point, you configured the laptop to work with the wrong SET of keys. I suggest you read the manual.
