|Since the touchpad last worked.....|
- have you, or could someone else have, dropped the laptop?
- have you, or could someone else have, spilled any liquid on the laptop?
(It doesn't matter if it was running or not at the time, if the main battery was installed - damage could have been done.)
Apparently your model came with Vista 32 bit.
- have you installed Vista from a regular Vista DVD?
- has anyone taken the laptop apart?
When did it stop working?
- after you, or something, installed software?
- after some other event?
- there are drivers for the Touchpad on the Toshiba site for XP OR Vista 32 bit - did you install the right version?
I know from experience...
- if you install an operating system from a regular CD or DVD, the touchpad on a laptop is often NOT recognized properly until AFTER the main chipset drivers have been installed for the mboard.
For this model, the main chipset drivers are listed as Chipset Drivers on the same page for your model where you got the Touchpad drivers.
- you may need to install additional hardware related software specific to the model as well.
It appears that doesn't apply in this case.
- a wiring connection problem between the touchpad and it's connection to the mboard can cause it to not be detected by the operating system at all, or for it to be detected but it cannot work properly.
- installing the wrong drivers for the particular can cause it to not be detected by the operating system at all, or for it to be detected but it cannot work properly.
But - it appears you tried the proper drivers, IF you got the ones for Vista 32 bit.
