By looking at your two posts and the action you have already taken, it looks like the problem is not of a software nature but hardware failure.
You have not mentioned how old is the laptop and how it was handled during it's lifetime. You have not mentioned what OS is there and were you able to boot into the OS.
One way of checking the keyboard and touch pad is that try to connect a USB keyboard and see whether you can operate all the keys. Similarly you can try connecting a generic USB mouse and see it functions.
If the system works with these external keyboard and mouse, then you can try to get a replacement keyboard either from local computer repair shop or directly from Toshiba. For mousepad it is not worth replacing it. Your friend can manage with a USB or wireless mouse which willl be cheaper.
Till the keyboard is replaced, he can manage the laptop with these devices.
