''Create factory default disc'' -button don't work.

You will loose all data you have put on the computer. When you turn it on right at the beginning there is a black screen and there are a few f key options.
They will flash up with the option when you turned it on, before windows kicks in. Take a look at the user manual to find out for sure.
Press the correct f key before windows starts up, then go through the menus in setup (it will look all crappy and dos like) and find restore factory settings (or something like that) and click yes.
It's a great feature, and will completely kill any virus or **** problems you have had and couldn't get rid of.
Hope this helps. I would appreciate your feed back as I do this for fun not pay.

Hi,

You can restore the computer back to factory default,to do so, follow the below steps: Turn OFF the computer, now as soon as you hit the power button, keep on holding "Alt" key & keep on tapping "F10" key, i.e Alt+f10, it will open the recovery console, select full factory restore and follow onscreen instruction. NOTE: This will erase all the datas on the computer.

You can also create a set to Recovery disk from the recovery partition, to do so

Start Menu> All Programs> Acer erecovery management> Click Create Factory Default Disk, if you receive any error code or unable to burn the disk, please contact Acer Technical support at 1 800 816 2237 and order for an Recovery Disk.

Thanks and regards,
Jitha

This is for windows 7:
Click the Burn button.

1. Open your Pictures library from the Start menu and select your desired photos.
2. Select the photos and folders you want to copy by holding down the Ctrl key and clicking their icons. Or, to select all the photos within a folder, press Ctrl+A.
3. Need to select photos from multiple folders? Don't select any photos or folders in this step. Proceed with the rest of the burn process and Windows 7 will open an empty window showing the newly inserted disc's contents: nothing. Drag and drop the photos you want to burn into that window. When you're ready, go back to the Pictures Library and click Burn.
4. 
   

5. Insert a blank CD or DVD into your writable disc drive.
   

6. Decide how you want to use the disc:
   

   1. Like a USB flash drive:
      

   Choose this option when you intend for other PCs to read the disc. Windows 7 treats the disc much like a folder, letting you copy additional photos to the disc later.

   2. With a CD/DVD player: Choose this option to create discs that play on CD and DVD players attached to TVs. Don't choose this unless you plan to view the disc on a TV. You can't add any images to this disc later, so be sure to get them all selected the first time.
      

7. Type a name for your disc and click Next.
   

8. Click the Burn or Burn to Disc button again, if necessary.
   

9.

Unlike other laptops, Acer laptops integrate a computer management utility called 'Acer eRecovery Management' to create backup of hard drive data, create restore point, reinstall applications & drivers, and reset Acer laptop to factory setting.

Step 1: Before starting your Acer laptop, ensure that there is no external storage device attached to it. Now start your laptop.

Step 2: Press 'Alt + F10' when the laptop starts booting, and wait for a moment while Windows loads the reset files.

Step 3: When 'Acer eRecovery Management' window appears, select 'Restore System from factory default' and click 'Next' to continue.

Step 4: Again click 'Next' to reset your Acer laptop. This process will erase all data from your hard disk and reset your Acer laptop to original factory settings.

Step 5: Click 'OK' in the notification window to begin the the resetting operation. Now wait while your Acer laptop is reset to factory settings.

Tips: You can also create a backup copy of your laptop data before factory reset. Simply click 'Backup' in 'Acer eRecovery Management' window.

If you face any issue with your Acer Notebook, feel free to get expert technical assistance at http://www.vtechsquad.com/acer-support/

This was taken straight out of the manual for your model, which can be found here.

Acer eRecovery Management
Acer eRecovery Management is a tool to quickly backup and restore the system.
You can create and save a backup of the current system configuration to hard
disk, CD or DVD. You can also backup/restore the factory default image, and
reinstall applications and drivers.

Acer eRecovery Management consists of the following functions:

1 Create backup
2 Burn backup disc
3 Restore and recovery

This chapter will guide you through each process.
Note: This feature is only available on certain models. For systems
that do not have a built-in optical disc burner, plug in an external
optical disc burner before entering Acer eRecovery Management
for optical disc-related tasks.

When using Acer eRecovery Management, you may be prompted to enter the
Empowering Technology password to proceed. The Empowering Technology
password is set using the Empowering Technology toolbar or when first running
Acer eLock Management or Acer eRecovery Management.

Create backup

You can easily create full and fast (incremental) backup images of your system
configuration to hard disk from the main Acer eRecovery Management screen.
Note: Fast (incremental) Backup is only available after a Full
Backup is made.

1 Press <Alt> + <F10> or select Acer eRecovery Management from the
Empowering Technology toolbar to start Acer eRecovery Management.
2 In the Acer eRecovery Management window, select the type of backup you
want to create using Full or Fast.
3 Follow the instructions on screen to complete the process.

Burn backup disc
Using the Burn Disc page of Acer eRecovery Management, you can burn the
factory default image, a user backup image, the current system configuration,
or an application backup image to CD or DVD.
1 Press <Alt> + <F10> or select Acer eRecovery Management from the
Empowering Technology toolbar to start Acer eRecovery Management.
2 Switch to the Burn Disc page by selecting the Burn Disc button.
3 Select the type of backup (factory default, user, current system,
application) you would like to burn to disc. Choosing to burn a user backup
will burn your most recently created backup image to disc.
4 Follow the instructions on screen to complete the process.
Note: Create a factory default image when you want to burn a
bootable disc that contains your computer's entire operating
system as it was delivered to you from the factory. If you wish to
have a disc that will allow you to browse the contents and install
selected drivers and applications, create an application backup
image instead — this disc will not be bootable.

Restore and recovery

The restore and recovery features allow you to restore or recover the system
from a factory default image, from a user created image, or from previously
created CD and DVD backups. You can also reinstall applications and drivers for
your Acer system.
1 Press <Alt> + <F10> or select Acer eRecovery Management from the
Empowering Technology toolbar to start Acer eRecovery Management.
2 Switch to the restore and recovery page by selecting the Restore button.
3 Select the backup point you would like to restore from. You can also
choose to recover the system from a factory default image, recover from a
previously created CD/DVD or reinstall applications and drivers.
4 Follow the instructions on screen to complete the process.

There is an error in the manual. In order to reset to factory defaults, turn on (with no disc inside), DO NOT OPEN THE DISC TRAY, just press the stop button on the player for 5 seconds (some solutions say 20 seconds).
