Hi Everyone,
Can someone help me, I am running windows 7 64 bit on this machine I have only had the computer a few days and the touch pad does not work. I know the hardware is ok because I have downloaded the driver from Synaptics site, but windows seems to loose it when I power down. Has anyone had this problem if so can you help.

Hi,
From the Start Menu, open All Programs, open Accessories, right click the Command Prompt and select Run as Administrator. In to the prompt type the following command and hit enter.
sfc /scannow note that there is a space between sfc and the /
Let the process complete, then type exit and hit enter. Restart the notebook.
Now reinstall the synaptics driver and when complete, reboot the notebook again. If on restart, the driver has gone AWOL again, from windows Control Panel, open Device Manager and open up Mice and Other Pointing Devices, right click on your Touchpad device and select uninstall. When this has completed, restart yet again and see if Windows will rediscover the device and install the appropriate driver.

Hi DavidPK,
Thankyou so much I could not beleive my eyes when it worked, it is good to know that people like you are out there who know more than the so called experts.
Glad you ve got it working
Hi Davidpk,
I do not believe it.. The pad became erratic and stopped working, looked in control panel and all of the driver info had gone all except the tab for synaptics. I installed again and got it working again only to have the same problem. Do you think it is a Windows 7 Problem. as when the pad is working it is fine for about three or four boot up s.
Sorry to hear it s playing up again. Try the following.
Download the latest Synaptics Driver installer on the link below and save it to your Desktop.
.exe
Next, shutdown the notebook, remove the AC Adapter and remove the battery. Now hold down the Power Button on the notebook for a full minute. Re-insert the battery, plug in the AC Adapter and start the notebook.
When windows has fully loaded, right click the installer on your Desktop and select Run as Administrator to start the installation. When this has completed, restart the notebook again.
If the above doesn t help the problem, the root cause may well be a Hardware issue and I would recommend returning the notebook to the retailer and getting a replacement - you shouldn t have to be working this hard to get a brand new machine to work correctly.
