Disabled the touchpad, now cant bring it back

The case:

I got annoyd by my thumb hitting the vaio Z31WN touchpad when docked, that coused the cursor to jump around the screen. Also, what had been bothering me was the missing scroll function from the touchpad.

I decided to install the synaptics 64bit drivers, the vision on my mind was to enable the "Disable touchpad when USB-mouse is connected" option, and possibly to get the scroll function.

Well, any of these did not work. I got no scroll, or no USB controlled disconnect. I got depressed, and for bandage, i disabled the ps/2 touchpad from the synaptics controll panel... I was happy

Time passes, i do some cleanup on the computer, and i spot the synaptics on the software list, thode "what the heck im going to do whit this since it had no use" and uninstalled it. Time passes again, and i need to grab the laptop on the go, and use it whitout the dock. When i needed to use the laptop, lightning hit me, and i forgot "damn, i disabled the mouse". Using the keyboard i navigated my way to device manager, in order to enable the mouse again. SUPLAIIIIIIIIIIIIIIIIIIIS!!! the device manager claimed that the mouse was allready in use.

So, i tryed to remove it, windows wanted me to do reboot. After reboot i get the baloon "New hardware has been installed". And it doesn't work.

So, i went to do expedition on the amazing jungle of the internets. I googled drivers by the laptop model, by the HW id of the touchpad, tryed everything that had eaven the slightest chanco to work... Nothing.

Device manager always shows the mouse ok, claims its fine and operational, tho the "disable device" button is unavailable (possibly cose there is underlying problem that keeps it hiddenly disabled).

If i remove the device, and reboot. After logon i get the baloon "New hardware has been installed" _but not_ "new hardware has been installed and is ready to use" like you usualy get. Could this have something to do whit the cause?

Then there's this: Randomly, after hibbernate the mouse works fine for ~20seconds. after that it just goes cold. but there is no precise method that i could repeat it. Its just plain random.




So, then this came to my mind: What if, when i disabled the touchpad from the synaptics, it somehow alternated the windows registry (or something) and created entry "disableTouchpad = 1". Now everytime the computer starts, it loads that line and disables the touchpad. I found that registry entry under the synaptics, but removing it, and enything that has anything to do whit the synaptics did not change enything.

I also figured that if i remove every entry from the registry from the physical hardware, the windows would rewrite it during boot. But, you cant remove those since they are in use.

Ive also checked the bios, but theres nothing even remotely connected to the touchpad.

Also tryed to reinstall the synaptics, and togle the touchpad off / on / off / on, whit reboots, and nothing...

So, any ideas? since im running extreamly low on good ones... (heck, i dont eaven have the bad ones anymore)


Thanks

You shouldn't have disabled the touchpad from the Device Manager... instead a better choice would have been the Control Panel>Mouse. Anyway if you have the drivers installed correctly go to the Control Panel>Mouse and make sure it's enabled... good luck.

PROBLEM SOLVED!!

Got tip to try booting on to Ubuntu-Live, and try if the mouse works on there... Well it did not. Went back to bios, in order to change the boot order back, and decided "heck, ill just give it a shot" and resetted bios deffaults... (tho, there was nothing on bios that eaven remotely had anything to do whit mouse)... Gues what, after booting to ubuntu, the mouse worked just fine. Rebooted to windows, and the mouse works.
