The touch screen don't work ? Do you use an external mouse ? Did you replace the external mouse if you have one?
1st gingerly, and softly pass your hand across the entire keyboard from left to right, then right to left touching ALL keys [[ ALL]] . go up and down the keyboard .
2nd take the eraser of the pencil and gently TAP all keys to UNstick any key that could be shorted out. If that don't work, get back to me so that I can show you how to use a WORD PROCESSOR to find your problem.

if the little button on top of the mousepad is in "off" position, the cursor won't move

Go to this page @ Toshiba Support for your model and download and install the Camera Utilty. Even though it says XP/Vista, almost all Vista Drivers will work with W7 Ultimate.

If your cursor is locking up, first make sure you are using the correct pointer device driver. if you are, then you need to run a utility to scan the drive for errors.

look into getting a bootable version of the utility pc-check it has a mouse utility to check as to whether or not the problem is software related.

Down on your task bar on the right there is a little screen that shows a green circle when you move your cursor. This is the Synaptics Pointing Device. Place your cursor over that and click your left 'mouse' button (just below where you tap). You will see 'tap to click'. If you click on that it will change it to your 'tap' function. That should solve your problem, hopefully. Hope this helps.

try going to device manager and right click on pointing devices and adjust the sensitivity.
