How to unlock a computer

Resetting the CMOS password on an Acer Aspire laptop is much more difficult than resetting the password on a desktop.
Disassembly steps vary from model to model, but on most models, you'll have to take apart the computer to access the CMOS battery.
Don't take apart the notebook if you don't have experience disassembling PCs.
After turning off the computer and disconnecting the AC adapter, take out the battery (different from the CMOS battery).
All visible screws must then be removed from the bottom of the notebook.
Remove all components stored to their separate compartments on the base of the notebook.
Turn over and open the PC. Lift up the switch cover and remove the screws securing the keyboard to the PC, if any are visible.
Remove the keyboard.
Remove the screws securing the monitor to the hinges, and then set the monitor aside.
Disconnect all visible cables connected to the motherboard; and then remove the screws from the top cover.
Remove the top cover to reveal the motherboard. Locate and then remove the CMOS battery. Leave it out of the notebook for 24 hours; then reinstall it and reassemble the Acer Aspire.
Other Options
If removing the CMOS battery fails to clear the password, or if you dont feel comfortable with the idea of opening your computer, you might be able to gain access to the computer using a backdoor password.
These special passwords were implemented to allow technicians to access locked computers. Not all models recognize backdoor passwords.
Most Acer Aspires use the Phoenix BIOS, and backdoor passwords for this BIOS include BIOS, CMOS, phoenix and PHOENIX.
All of these passwords are case-sensitive.

Press the "Ctrl," "Alt" and "Delete" keys on your keyboard simultaneously to unlock your Gateway computer.

Type the last logged-on user's login information and click "OK" if you see a locked computer message along with "Only domain/username or an administrator can unlock this computer."

Press the "Ctrl," "Alt" and "Delete" keys once again when you see the Unlock Computer window disappear. Log on as usual.

hope this helps

Hi,

How to Unlock an iPod


Your later generation Apple iPod can be locked to protect your personal data from anyone else's eyes. There are a variety of ways to unlock it depending on your access to the combination, the primary computer linked with the iPod, or neither.
Difficulty: Easy
Instructions

Unlock with the Combination

Remember the 4-digit combination you used to set the screen lock.

Enter the exact combination. If the combination is correct, the iPod unlocks and displays the screen you were on before you locked it.

The numbers on the screen flash red if you enter the code incorrectly.
Unlock with the Primary Computer



Plug the iPod into the primary computer linked to that iPod, the first computer you synchronized it with unless you have designated another computer as the primary computer.

Open iTunes and sync the iPod as normal.


Remove the iPod, following the normal removal procedure. The iPod unlocks automatically as you remove it.
Unlock by Restoring


Restore the iPod to factory settings if you do not have access to your primary computer. This erases all of the data you have stored on the iPod.

Plug your iPod into the new computer you want to be the primary computer. Open iTunes and click on the "Restore" button.
