Acer extensa 4220 bios password


There's no way that we can determine the BIOS password of your laptop. But if you can disassemble your laptop and locate the CMOS battery you can remove the CMOS battery to reset the BIOS together with the password. After resetting the CMOS battery you will no longer be asked to enter a password for the BIOS when you turn on your computer. However, there are instances that even though you reset the CMOS it's still asking for the password, for this concern, the computer manufacturer should deal with this concern.

Actually you can clear the BIOS password by resetting the CMOS jamper. If you are familiar with CMOS jamper it is easy for you. Open your laptop with the use of screw driver. Once you are already open it locate the CMOS jamper near the CMOS battery at the south bridge of your laptop motherboard. Remove the jamper with in 5 seconds after that reinsert and trun on your laptop.

Acer Extensa supports two model of HDD installation 1) AHCI and 2) SATA.

Windows Vista get installs on both but for Windows XP you need to Enable SATA option.

For that go into Bios, Change option of Hard Disk from AHCI to SATA. After that you can install both XP as well as Vista.
