I have an Acer Aspire 5532, and it used to have a scroll option on it, on the side of the touchpad. I used a regular mouse plugged into the USB drive for a while, with the touchpad disabled, but it broke and I'm back to using the regular touchpad. however, somehow the scroll option got disabled and after quite a bit of trying I still can't figure out how to re-enable it. does anyone know how?

I fixed the problem by clicking Windows » Start, typing "touchpad" into search and clicking on "update drivers".

Update Synaptics, then restart and it'll all be good.

In Windows 7, you can go into the start menu and type "change mouse wheel settings" and you should be able to edit your touchpad's settings there.

You may be having a driver issue if the above solution doesn't take you to any touchpad options. I know on a clean install on my dell laptop, my touchpad scroll didn't work until i reinstalled the driver. Acer drivers are available at http://support.acer.com/Default.aspx

To access your model go to Drivers & Downloads under the Service & Support link on the menu, install whatever you need under touchpads, and then "change mouse wheel settings" should work (again, if it doesn't already).

This isnt uncommon. Often when you download a mouse driver, you get more than the driver. They will install their own mouse applet/software in the control panel and disable the software that was there before. So when you go back to the original hardware, the software no longer applies and you are stuck with a partially functioning device. –  Keltari Aug 23 '11 at 21:51

I've got an Acer laptop too. I need to press the Fn button and hold it and then press the F7 button. It has blue square on it with a hand over it.

If you do it again it'll enable your touchpad.

just hit Fn (function key) and F9 at the same time. Same thing happened to me. Couldn't figure it out for a year. Felt like an idiot when I found out how to turn it on again.

better install following package to your machine and see, it worked for me.

TouchPad_Synaptics_15.1.18.0_W7x86W7x64_A.zip

Press fn + f12/scroll lock, it should then unlock the scrolling bar.
