I have a toshiba satellite a105-s4094. I recently installed the new keyboard, and now I'm in a world of hurt. The mapping is now all screwy. Some keys work and some don't. Pressing some keys causes the keyboard to register multiple keys. I think it's a problem with the driver but I can't find an updated one to install. I can't even figure out how to install my old one over again. One other thing - the keys that don't work, when i press them the light on the power button blinks off. Any ideas?!
