No Bios Password

[Asphaltgeier]

Hello Everybody, 

i received an old Acer 7738g Laptop with Win7 as a gift to my children.
The problem is, that the old user forgot the Bios entry password.
I installed new SSD Harddrives, but i have no choice to setup any options in the bios.
I removed the battery for 24h, i flashed the bios from 1.11 to 1.13, but there is always a Passwort  

My search in the net was negative, and Acer doesnt support a Bios Password recovery

Is ist possible to flash a Bios with deactivated Password?

Can someone help me to reanimate the laptop.
