If you have forgotten your password and it is stored in the BIOS, then you can reset the BIOS to the factory default state by removing the BIOS battery, wait for over 1/2 hour for the BIOS to discharge and wipe its contents, then reconnect the battery. You will need to reconfigure the BIOS before Windows opens.

I do not know this model, but if the password is stored in an EEPROM chip then it is near impossble to reset it without knowing the actual password. It would be difficult to remove, if you know a friendly hacker with a piece of hardware that can read the contents of the EEPROM chip and then identify the password, so he can tell you what it is.
Best of luck.

Bios password


The master password for Compaq is "compaq"
If that doesn't work you need to use a jumpe on the motherboard:
This Jumper is often named like: "RTC_CLEAR" , "CLEAR CMOS" , "CLRCMOS" , "CLRCMS". His position is often near by the motherboard battery. You will need to reconfigure any BIOS changes that you have done.

Password


Some BIOS manufacturers implement a backdoor password.
The backdoor password is a BIOS password that works,
no matter what the user sets the BIOS password to.
These passwords are typically used for testing and maintenance.
Manufacturers typically change the backdoor BIOS passwords from time to time.

Clear power on password


Removing the Time of Year battery will clear the BIOS password. It is located on the underside of the n610c behind the panel covered by the Microsoft COA label. A small phillips screwdriver is required to remove the two screws on the panel. Carefully lift the BR1225 battery with a small flat blade screw driver.

After 10 minutes re-insert the battery. The BIOS Password should now be cleared, as well as other BIOS settings, the time and date.

Frogot password


It would help if you will clear the BIOS or the CMOS of the laptop. It can be cleared by pulling out the cmos battery of the laptop for a long period of time or by locating the jumper/dipswitch on the motherboard that would clear the BIOS. You may go to these links on ways on how to clear an unknown BIOS password.
