Toshiba Tecra M4-S435 is Tablet PC. Windows XP (Profession) has no option of touch screen.
In order to use the feature, you need to install Windows XP Tablet PC Edition or you may install Windows 7, which supports this feature and you would definately be able to use stylus and touch screen, as I have installed Windows 7 and its working fine with all the drivers etc.

Hope it helps! Good Luck!

The GPU graphics chip fails a lot in this model. It usually means a motherboard replacement. I've had it fixed 4 times at a cost of $600 each time at a authorized repair center but it reoccurs a year after. The GPU fan doesn't come on enough to cool the graphics chip so it fires or gets unseated.

I would look on ebay for a smashed one first.
or one with a malfunctioning screen. When I did an e-bay search for your model It came back with 509 results. The bottom link is a repair specialist for that kind of notebook.
