Motherboards Unknown bios password

Just thought I would get you guys opinion on this one. We had a Acer laptop come back from a customer where they had forgotten their Windows login password and also they had a BIOS password which they had forgotten. Is there a way of recovering the password without changing the motherboard?

P.S. we tried removing the cmos battery from the laptop.

 

Unless you can find a manufacturer password, then probably not buddy. Sorry
(we had the same problem at work, but the laptop was still in warranty with dell, so we dragged a 9V battery over the motherboard and phoned it in as a dead mobo )

 

If the battery pull doesn't clear it the easiest way is to flash the bios. Alternately there is a bios password clear utility on the UBCD.

 

What model?

I've come across a couple of laptops with BIOS and HDD password, they had a part on the mobo you "short" clearing the BIOS like a CMOS reset

 

Here is a list of some default BIOS backdoor passwords if you can be bothered!

Or you could do what some have suggested and call the manufacturer and give them the serial number on the back to get them to give you the backdoor password for your laptop.

 

Thats a handy little list.
