Model M52264
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.
