Scoll bar action on touchpad works outside the scroll area

I trust that you understand that scroll bars are only visible if more than 1 page is to be displayed. If you have magnified a particular page, the scroll bar may be outside the view of the screen - on the right side, Scroll to the left until you see the right border.
Perhaps you are referring to the touchpad.
The scroll feature on the touch pad is not visible. You enable the touchpad by tapping twice on the upper left corner of the touchpad. A lite will appear in that corner when the touchpad is ON.
Then the scrolling feature is enabled on the right side of the touchpad. Simply run your finger up and down the right side of the touchpad. For more information, refer to the User Guide here:

I suppose there is no hardware fault. Please reinstall touchpad drivers from the following website and try going into Mouse settings and check if scroll bar is enabled. Install the one apppropriate to your hardware for eg if your touchpad is ALPS install ALPS driver.

Download free driver for notebook Acer Aspire 5532 Windows 7 XP Vista

Step 1:
The touchpad of Hewlett Packard Compaq notebook computers comes equipped with vertical and horizontal scroll capabilities. Dragging your finger on the top or side of the touchpad will scroll in windows equipped with scrollbars. This feature takes some getting used to if you're used to a regular mouse or a wheel equipped mouse. If you prefer to not have vertical and horizontal scrolling performed from the touchpad, one or both features can be disabled.

Double-click the red Synaptics icon on your task bar. If it's not displaying, open the Control Panel and click on "Mouse" in Windows XP. In Windows Vista/7, type "Mouse" in the search field of the "Start" menu and click on the Mouse result. Click on the "Device Settings" tab and then click on the "Settings" button. The Properties for Synaptics TouchPad dialog box will appear. Click on "Virtual Scrolling" in the "Select an Item" box on the left. Clear one or both scrolling features in the "Virtual Scrolling" section. Click "Apply," and then "OK."

If the scroll part of the touchpad is not working it indicates a hardware issue, brand new! I would return it to the place of purchase, this should not be issue.

go to control panel and open mouse option, from here selct the "touchpad" tab,now you should see a line that display the name of the your hardware ( the touchpad name) and below there is a button named "advance configuration" or simply "configuration" or "setting" ecc. Push it.

From the new windows you can control a very large number of options ,not only you can activate scroll in two direction ,but you can also decide the dimension of the touched area interested in the action.

The "Touchpad is very sensitive; if you look while scrolling, the "scroll-bar" will turn (Blue), click on the ("scroll-bar"), until it turn "Gray." Note: "You ca use the Pointer Device / Touchpad without using the Scroll-bar, basically anywhere on the screen; ("bottom scroll-pad" = left to right"), and ("right -side edge scroll-pad = up & down").

You say it has been restored so I assume that Windows has been re-installed. If so then it is probably using the generic Windows touchpad driver and you need to update to the specific touchpad driver. Go to HP Website and download the touchpad drivers.

I have found a solution related to your issue:

The option to enable or disable the scrolling option for the notebook touchpad is generally available by going to the Control Panel, then selecting Mouse. Within that area, go to Device Settings, select the touchpad from the list of available devices, then click Settings. There should be an option for "virtual scrolling" - click on it, and you should be given the options to turn on or off both horizontal and vertical scrolling for the touchpad control.

Double click the icon in the toolbar. Click the device settings tab and then hit setting. select buttons in the list on the left side. Hit the plus sign(maximize) and select scroll up button action....scroll down button action...Etc. For each action select what you want it to do and just hit apply and move to the next. Once you have selected the action for scroll up, down , left, and right hit apply again just to be sure and try it. It should work. I just did it on my 5630 but Im assuming it works the same.
