Acer Extensa 4220 Bios Password Problem!!!

[shk0915]

I am trying to remove or reset password for Acer Extensa 4220. I already tried several times removing battery but no luck on resetting the password.
Anyone know how to reset or disable the BIOS password? Thank you.

On most modern laptops the BIOS password is hardcoded into a security chip on the motherboard, and requires an EEPROM reader & writer for this purpose.

this is a paid program that will prob not work on a laptop due to how the password is stored, in eeprom chip

manufacturers set bios back door passwords that sometimes work, i believe acer use the phoenix bios
it will say on startup what bios its used, mine says award bios for example

then go here and check see if there is a password
