Gap name in Aspire 5740/5740D/5340 Series is G77.  
Steps for Clearing BIOS Password Check
If the user sets the BIOS Password (Supervisor Password and/or User Password) for a security reason, the 
BIOS will ask for the password during system POST or when the system enters into the BIOS Setup menu.  If 
it is necessary to bypass the password check, the user needs to short the hardware gap to clear the password 
by following these steps:
Power off the system, and remove the HDD, AC adapter and battery from the computer.
Open the back cover of the computer and look for the hardware gap on the main board as shown 
in the picture(s) above.
Use an electric conductivity tool to short the two points of the hardware gap.
Plug in the AC adapter while retaining the short condition on the hardware gap. Press the power 
button to turn on the computer until the BIOS POST routine is finished. Finally, remove the tool 
from the hardware gap.
Restart the system. Press the F2 key to enter BIOS Setup menu.
