Is there an overide bios password for my acer travelmate 2450 as i can not access the bios as it asks me for a bios password that i dont have

Try default codes 1234 0000.
If not you can reisntall a new bios.

if you dont have the bios password you will need to take apart the laptop and de-solder the bios battery leave it of for 10 minutes resolder it making sure the polarity is correct and there will be no password when you re-boot it

to reset the bios password go to acer service center and tell them that u have forgotten ur password and ask them to reset it.

u got to replace ur BIOS. but der r ways to recover the BIOS password using default passwords, i need to get to know ur MOTHERBOARD build.

try useing a cd of xp to repair it then going to http://www.filehippo.com and downloading AVG.9.00

Let me know if you have any issue. Thanks for using Fixya.com Thanks Shereena

Check on motherbord again you can find cmos cell it is look like round battery cell.
Then pull it for 10 minutes so all bios settings are defaults.
Also you can clear bios with jumper find jumper on motherbord it has 3 -pin 1-2-3 right now jumper is in 1-2 position set it to 2-3 position so your bios is clear.Then again set it to it's original position.
then it not ask for password.
Let me know if you need more assistance.
Thanks.

It is asking for the password that was set up with the finger print reader,Not the bios password.

you have to open the back cover and there you can find  a CMOS battery located on the motherboard ....try to remove  and insert it ..it will reset the BIOS password ...
