I have a satellite L305D-S5893 laptop that i bought last year. My son reported that the keyboard and touchpad do not function. So i reformated the computer with the provided toshiba restore disks. I erased the harddrive and reinstalled the vista. However the keyboard and mouse still do not function. The internal keybaord and touchpad only works in the bios settings and when i have to choose boot menu and what not. When i plug in an external keyboard and mouse they work fine under vista. This obviously is not a great tradeoff because it limits the portablity of my laptop. It would be nice if i could get the touchpad and internal keyboard to work. I have tried to update the drivers and nothing has worked.Has anyone else experienced a similar problem? And how can i fix this? I am willing to try troubleshooting procedures.
