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.

PASS BIOS ACER 2930 ASPIRE


Hi the only possible way to reset the password in the BIOS is to reset the CMOS battery. It is located in one of the panel below the sys (you must have proper expertise to do this) towards the right hand side. The battery is set on a jumper You first need to disconnect all power source i.e adaptor and battery. than remove the panels to try and locate the CMOS Battery. Remember not to tuch anything else or connect any of the cables any where else it may cause a problem for the sys and you. Once the CMOS battery is reset the BIOS password will have gone.
All the best

Here is the data that I have found: In order to have the BIOS or hard disk password removed (This include any biometric security), the notebook will need to come in to our repair depot for password removal. This service is not covered by warranty and unfortunately there is no other recourse to remove a BIOS or HDD password from the notebook. The flat fee for BIOS password removal is $100.00 US dollars plus tax. If it is a BIOS or HDD password and you would like us to service it for you, please contact our telephone technical support line at 1-800-816-2237.
