The password reset for the bios on a Dell Lattitude D620 is "alt enter". To get there upon boot up hit F2 scroll down to security and go from there. Be sure to type case sensitive and follow with "alt" then "enter" in the password field.
If the above did not work, try the below link which has the password generator tools attached at the bottom of the page.

You'll need to request a temp password from Dell. Contact their technical support and provide them the code you received. Be also prepare to confirm the ownership details of the laptop. If it is not registered to you, confirm with the previous owner if they are the original owner. Then provide the details to Dell support once requested. What they'll do is request a temp password to be given to you which you can enter on the password prompt that you're getting then if I am not mistaken, you will be asked to hold the CTRL key and press the ENTER key twice after typing the temp password provided to clear/turn off the BIOS password. Let us know how it goes.

Some manufacturers use a backdoor BIOS password for their tech support.
Try the password "Dell" (without quotes).
Hope this resolves your problem.

The Dell Latitude D620 Notebook PC has a CMOS battery.
If you remove it, and then perform a drain of residual power, this will reset BIOS back to the factory default settings, and there will be no password set in BIOS anywhere.
Drain of residual power.
After removing the Coin-Cell Battery, press the Power On button, and hold it in. Hold it in for a count of 5 seconds. Let go. Do this procedure two more times.
To remove the Coin-Cell Battery.
Dell Inspiron D620 Service Manual. Free from Dell Support,
Click on Coin-Cell Battery in the list.
1) The first order of business is to remove ALL power to the laptop, (Notebook)
Remove the AC adapter (Charger) and Battery.
2) Work on a table, use an ESD wrist strap if available. Connect the alligator clip to a good ground source.
An ESD wrist strap's average cost is around $3 to $6. I connect to the metal frame of an empty desktop computer case. (Electro Static Discharge)
Your body carries Static electricity. Static will fry out (Short Circuit) the hardware components inside a computer.
(Some such examples are Processor, Ram Memory, motherboard chipset, graphics chipset, (GPU), and so forth)
You aren't really going into a critical area, as far as Static shock to the hardware components is concerned, but why take a chance if it only costs $3 to $6 for cheap insurance?
3) I would suggest wrapping a piece of tape so it is double-sided, and stick to the table. Stick the screws you will remove on the tape, make a little notation of where the screws came out of.
[Ordinarily I would advise using a multi-compartment container, and marking the compartments for where the screws came out of. As you read on you'll see why I changed this ]
You will remove the Hinge Cover. (No screws)
Then you will remove 3 screws that holds the Keyboard in place.
(The Keyboard is not removed all the way to access the Coin-Cell Battery)
4) The Hinge Cover is the flat piece of plastic directly below the LCD screen, and above the Keyboard.
Contains the Keyboard Status LED lights, Volume Control buttons, Mute Button, and Power On button.
The Hinge Cover has plastic tabs on the front and rear edges. These tabs hold the Hinge Cover in place.
These tabs snap into place when installing. (They 'pop' when removing)
5) At the top of the Keyboard are three Philips head screws to remove.
Then pick the Forward side of the Keyboard, (Towards the LCD screen), up to a slight angle, and slide the Keyboard forward until the tabs at the rear are free from the Palm Rest.
(The Keyboard has plastic tabs that are on the side towards you. If you lift the Keyboard straight up at a 90 degree angle, you risk breaking the tabs off, and damaging the Palm Rest)
You can only lift the Keyboard so far. There is a flat flex cable going from the Keyboard, to the motherboard.
All you need to do is rotate the Keyboard back towards you, and lay it on the Palm Rest.
(Top of Keyboard that faces the LCD screen, is brought up, and over until it lays on the Palm Rest)
This will give you access to the Coin-Cell Battery.
The Coin-Cell Battery is a watch type of battery. May be similar in size to a CR2032 as used in most desktop computers, I don't know. It is a 3 Volt battery.
It's in a plastic 'bag' type of holder with a Positive, (Red) wire, and Negative (Black) wire coming from the 'bag' holder.
The Positive and Negative wire end in a white small connector.
This is an example,

Seems that you need to unlock the administrator password of your computer's BIOS. According to Dell, the best way to do this is as described below:
If you forget the primary password and do not have an administrator password assigned, or if you have both a primary and an administrator password assigned but forget them both, contact your system administrator or Dell (see Contacting Dell).
You can refer to the following document from Dell for more details about different kinds of passwords:

Well, BIOS passwords are very difficult to get past if you don't know them or have forgotten them. You can try, notice I said try because sometimes this works and sometimes it doesn't, removing the battery and the power supply plug then holding the on off button down for 60 seconds. The procedure actually calls for 10 seconds to discharge the capacitors and cause a BIOS reset but do it for 60 seconds just to be sure. I couldn't explain how this works or why but occasionally it does. Your other option would be to try using a program to recover BIOS passwords called LCrack. It works 90 % of the time even though it wasn't specifically designed to work on BIOS passwords. I will tell you this, in cases when the password was put on the machine by a technician who thought they were helping most will use something like admin, administrator or in your case delladmin or d620admin. This assumes the previous owner just forgot what they put in the password slot or don't remember putting a password on the device. Humans being Humans we tend to use passwords that are fairly easy to identify, to us anyway. If the person did put the password on the device and just forgot since he wasn't accessing that area very often he most likely used the same password he had for logging the computer on or some combination of that password.

First open your dell and remove cmos battery for about 30 minutes then put it back and check. if this doesn't work, on its motherboard, look for the jumpers near the CMOS battery.
Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS,
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin. Make sure to turn the PC off before opening the cabinet and resetting the jumper.
You may use the BIOS/CMOS Password Recovery Tool. Simply boot your PC to DOS and execute the program, you will get access to the password.
