Touchpad Synaptics V7,5 on my laptop (HP) works now and then...I have downloaded all the new drivers. It suddenly stops, and when I close my laptop and switch on again it works until next time....

Have you checked the settings of your synaptics? Usually there's an Icon on the taskbar for synaptics you can right click it and check if "disable touchpad if usb pointing device is present" is checked, if so uncheck it then your touch pad should work again.
Here's a link for a step by step instruction though this is for windows xp but steps are the same. Hope this works for you:

For the full capabilities of the touchpad, you will need the Synaptics touchpad software and drivers. Look for your operating system here and download and install the Synaptics PS/2 Port TouchPad Driver under Keyboard and other input devices.

I am assuming here that all the functions of your touchpad are working correctly, and all you can't do is scroll.

Often times the Synaptics controler, which is the controler and the driver for the touchpad, will get corrupted, de-activated or will just stop working. The easiest thing to try would be to download the synaptics drivers from the support section of you computer manufacturer's website, then go to your control panel, select add and remove programs, find Synaptics in the list and uninstall it. Then you can go ahead and install the drivers you just downloaded. This usually fix the problem 80% of the time. If you provide your computer maker and model I can even send a link to download the drivers.

check out synaptics driver software if its running while windows loads up!

Hi there.
The touchpad drivers could be corrupt, try reinstalling the touchpad drivers again.
Go here to Toshiba Support fill in the details of your model laptop and download the synaptics touchpad driver and reinstall it, see if that helps.

Good luck and thanks for choosing FixYa!!

I had the same problem after purchasing an HP laptop with a Synaptics TouchPad. After using a wireless mouse for awhile, the TouchPad stopped working. The TouchPad light was white, indicating it was enabled. No TouchPad devices was listed anymore in the Mouse Properties in the Control Panel. I tried reloading the driver but nothing changed.

After shutting down the laptop and removing the battery (according to owner’s manual) it worked again. After turning on the laptop, make sure the TouchPad works. Then go to Control Panel, Mouse, Device Settings tab, and make sure a Synaptics TouchPad is listed in the Devices list and that the Enable button is grayed out.

Hi!
I resently had the same problem on my HP laptop and search Google for possible solutions. No solution works until I tried Windovs Update and then got 5 alternatives - Synaptics PS/2 port TouchPad was one of them. I update and restart and finally solve this problem.
