Hi there,

Only way is to remove the CMOS battery for an hour or two and hook it back. It should work.
Optional is conatct Acer they would have a Default password for all the machines that they produce.

Hi,
1. Go and download the bios file - ftp://ftp.work.acer-euro.com/notebook/asp.../bios/v1.06.zip
2. There should be a file call AG1A-106.EXE inside Alviso folder, just extract this file to the location you like.
3. In windows, use cmd (Command Prompt) to run this application.
4. The syntax should be ---- AG1A-106.EXE /ldcmos /reb -----
5. It may take 1 minute to load up, when it appears, just flash it.
6. Computer will restart after flashing and password should be cleared.
7. Don't forget to set back the BIOS settings if required.

Hope this helps!

There is only one way to clear cmos (BIOS) passwords and I'll show you the procedure.....

Steps for Clearing BIOS Password Check

If users set BIOS Password ( Supervisor Password and/or User Password ) for a security reason, BIOS will
ask the password during systems POST or when systems enter to BIOS Setup menu. However, once it is
necessary to bypass the password check, users need to short the HW Gap to clear the password by the
following steps:

q Power Off a system, and remove HDD, AC and Battery from the machine.

q Open the back cover of the machine, and find out the HW Gap on M/B as picture.

q Use an electric conductivity tool to short the two points of the HW Gap.

q Plug in AC, keep the short condition on the HW Gap, and press Power Button to power on the
system till BIOS POST finish. Then remove the tool from the HW Gap.

q Restart system. Press F2 key to enter BIOS Setup menu.

q If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and
try again.

NOTE: The steps are only for clearing BIOS Password ( Supervisor Password and User Password ).
