Touchpad

The built-in touchpad is a pointing device that senses movement on its surface.

This means the cursor responds as you move your finger across the surface of

the touchpad. The central location on the palmrest provides optimum comfort

and support.

Touchpad basics (with two buttons)

The following items show you how to use the touchpad with two buttons.

• Move your finger across the touchpad to move the cursor.

• Press the left and right buttons located beneath the touchpad to perform

selection and execution functions. These two buttons are similar to the left

and right buttons on a mouse. Tapping on the touchpad is the same as

clicking the left button.

backup copies to a USB drive.

2 Restore:

• Restore Operating System to Factory Defaults

• Restore Operating System and Retain User Data

Recovering your system (Optical

drive)

If calling Acer support did not help fix your problem, you can use the Acer

eRecovery Management program. This will restore your computer to the same

state as when you purchased it, while giving you an option to retain all settings

and personal data for later retrieval.

To recover your system

1 Perform minor fixes.

If only one or two items of software or hardware have stopped working

correctly, the problem may be solved by reinstalling the software or the device

drivers. To recover software and drivers that were pre-installed at the factory,

see

"Recovering pre-installed software and drivers" on page 17. For instructions

on reinstalling software and drivers that were not pre-installed, see that

product’s documentation or technical support Web site.

2 Revert to a previous system condition.

If reinstalling software or drivers does not help, then the problem may be

solved by returning your system to a previous state when everything was

working correctly. For instructions, see

"Returning to a previous system

condition" on page 18.

3 Reset your system to its factory condition.

If nothing else has solved the problem and you want to reset your system to

factory condition, see

"Returning your system to its factory condition" on page

19.

Types of recovery

Recovering pre-installed software and drivers

As a troubleshooting step, you may need to reinstall the software and device

drivers that came pre-installed on your computer from the factory. You can

recover using either your hard drive or the recovery discs you have created.

• New software: If you need to recover software that did not come pre-

installed on your computer, you need to follow that software’s installation

instructions.

• New device drivers: If you need to recover device drivers that did not come

pre-installed on your computer, follow the instructions provided with the

device.

To recover your pre-installed software and drivers:

18

1 Click Start > All Programs > Acer, then click Acer eRecovery Management.

- OR -

If you are recovering from your driver and application recovery disc, insert it

into

the disc drive, then go to Step 3 after the Acer Application Recovery main

menu opens.

2 Click the Restore t

ab, then click Reinstall Drivers or Applications to display

the Acer Application Recovery main menu.

3 Click Contents to show a list of software and device drivers.

4 Click the install icon for the item you want to install, then follow the

ons

creen prompts to complete the installation. Repeat this step for each

item you want to reinstall.

Returning to a previous system condition

Microsoft System Restore periodically takes ’snapshots’ of your system settings

and saves them as restore points. In most cases of hard-to-resolve software

problems, you can return to one of these restore points to get your system

running again.

Windows automatically creates an additional restore point each day, and also

each t

ime you install software or device drivers.

Tip: For more information about using Microsoft System Restore,

click Start, then click Help and Support. Type

windows system

restore

in the Search Help box, then press Enter.

art > Control Panel > System and Security > Action Center, then

click Recovery.

2 Click O

message box will appear.

4 Click Yes. Your system is restored using the restore point you specified. This

process may take several minutes, and may restart your computer.

Returning your system to its factory condition

If your computer experiences problems that are not recoverable by other

methods, you may need to reinstall everything to return your system to its

factory condition. You can reinstall using either your hard drive or the recovery

discs you have created.

Warning: This complete recovery deletes everything on your hard

drive, then reinstalls Windows and all software and drivers that

were pre-installed on your system. If you can access important

files on your hard drive, back them up now.

If you can still run Windows, see "Recovering from within Windows" on page

19.

If you cannot run Windows and your original hard drive is still working, see

"Recovering from the hard drive during startup" on page 20.

If you cannot run Windows and your original hard drive has been completely re-

formatted or you have installed a replacement hard drive, see

"Recovering from

your recovery discs" on page 20.

Recovering from within Windows

Click Start > All Programs > Acer, then click Acer eRecovery Management.

Click the Restore tab, then Restore Operating System to Factory Defaults.

Click Yes, then Start. A dialog box will display information about the hard drive

that the operating system will be recovered to.

Warning: Continuing the process will erase all files on your hard

drive.

Click OK. The recovery process begins by restarting your computer, then

continues by copying files to your hard drive. This process may take a while, the

Acer eRecovery Management screen displays the progress.

When the recovery has finished, a dialog box will prompt you to restart your

computer.
