get to the mouse manufacturer web site
select the down load for your model to suit vista
down load and run

none, except i don't understand you

Just buy a USB wireless mouse. There is a transceiver that plugs into the USB port of the computer, the size of a thumb drive, and it sends and receives signals to the wireless mouse. In my opinion, a wireless, optical mouse is the best. Normally the footprint (size) of the mouse is smaller than a desktop one as well if you choose. With Vista, just plug it in the USB port and windows should install the drivers without any disks. But if it doesn't just insert the disk that comes with the mouse. You only need a driver for it. A driver is a set of instructions that tell the device what to do. Every piece of hardware in your computer has a specific driver.
I hope this helps and good luck.

Sounds like a Ebay sold mouse with non matching receiver to mouse.
Best laptop wireless mouse to buy in my opinion is Logitech VX Nano from Staples or some store like it.Work wonderful and battery life excellent. Windows Xp,Vista,Windows7 install the driver auto for you. Don't need the cd at all

The mouse pad maybe faulty or the ribbon cable from the mouse pad to the motherboard may not be properly connected. Reseat this cable.
You can connect an USB optical mouse to the laptop. I prefer you use a USB mouse all the time over the mouse pad.

Some laptops have a key sequence to activate or disable the onboard touchpad.
Look for Fn+F8(or another combination) the key should have a mouse symbol on it.

try to boot ur laptop with disc manager cd or win XP.
if doesnt works then try win 98 cd and delete ur C:/ partiton and install new vista

You have a button just to do that simle task, its un the upper right side and it has a touchpad on it, press it, looks like a display but its a button :)
