Question about Computers & Internet

12 Answers

I bought a Dell D620 and I noticed that some BIOS features are password protected. The previous owner said he doesn't know anything about it, so I'm not sure what should I do now. Any ideas would be appreciated. The laptops service tag is 4YXMT2J-595B, if it's of any help.

    I have tried this in the past and tried it again now, but it does not solve the problem.



    Let me detail the problem: I can install the OS and use the computer,
    and I can view the BIOS settings, but I cannot edit them. I need the
    "master" password, which (from what I read on forums) is generated using
    the service tag I provided.



    In other posts on FixYa I saw experts that provided these passwords, but
    as they are attached to those users service tags are useless to me. I
    am waiting for one of those experts to help me too.



    Also advising me to buy 50$ worth of service/software to unlock my BIOS
    is not an option. I already paid FixYa for a premium response, so I'll
    wait just for that and hope it was worth my time.

    Removing the CMOS battery doesn't work. Tried it long before posting here.
    Also, I already have software that can remove/reset the BIOS password (for free), but as with any software there's a possibility it can brick my laptop. So I want to try the alternative before taking this risk.

    Contacting Dell would not solve the problem. To help me in this case I would have to make some sort of transfer of ownership.
    I got the computer on a ebay-like website a year ago and I don't have the contact data of the previous owner anymore.

  • limpangel Nov 12, 2010

    Unfortunately the set of passwords you gave me didn't work.
    Can you send me more to try out? Thanks.

  • limpangel Nov 12, 2010

    cmospwd does not work.
    I can boot and install any OS I like. I can view the BIOS settings but I cannot change them.

    Also firmware upgrade does not work.

  • limpangel Nov 13, 2010

    @joecoolvette: I don't use Windows. It is not a problem with the OS, the OS works fine, the laptop works fine.
    Just that I have access to BIOS settings, but I cannot change them.
    I have tried all the solutions provided here on FixYa even before posting, like:
    - removing the CMOS battery (no jumpers available on the motherboard). Left it 24h disconnected, pressed the power button, etc. to drain the power left in.
    - Dell support is not an option because it's out of warranty and Dell doesn't offer support in my country. Also I cannot prove ownership, I got the laptop from an eBay like website a year ago and I don't have the contact data of the previous owner anymore.
    - upgrading the firmware does not work
    - all the free software I tried doesn't work: cmospwd, pass generators, !bios, Ultimate Boot CD, etc. (and I don't want to pay 30$ for a piece of software that I don't know it will work for sure)
    None of these work.

    All I want is an educated answer from someone who knows this certain model of notebook and knows what he is talking about. That means he knows that none of the conventional approaches work or at least has knowledge of the 3 kinds of passwords this BIOS can set (admin, system, hdd). If that expert can provide me with a password to override the one set right now would be perfect. If not at least give me an straight answer with clear explanation on why it is not possible and with alternatives that are not listed above.

  • limpangel Nov 15, 2010

    Transfer of ownership is available only in the same country. Quote from Dell form:
    "NOTE: Transfers can only be made within the same country (US to US, Canada to Canada, Mexico to Mexico, etc.)". As far as I remember the previous owner said he acquired it from a German engineer and I don't think they made the ownership transfer. And I'm not in Germany.
    Also because I'm not in or from the US, I cannot get support through e-mail. I get a warning message like so:
    "Our records indicate that your service tag belongs to a system that was purchased outside the United States." and "Traveling outside your home country with a Dell laptop that is included in the Dell International Services Program? Click here to find support and service resources for your destination country."
    Europe's support list is limited only to phone numbers and my country is not listed there. I tried to call some companies listed on my countries Dell website, but they only provide corporate support and only if you have a valid warranty.

  • limpangel Nov 20, 2010

    I already knew about that post in Techspot forums before posting this question. I am a member myself on those forums.

    Anyway I will accept your solution even if it did not solve my problem because the other solutions were ****. Yours came close to what I was looking for.

    Thank you.

Hi,
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.

  • Rodie Nov 15, 2010

    if in case you do not have the details of the previous/original owner, you may try to request an ownership transfer. If you can boot the system to Windows, make sure to use it to access the following link



    http://tinyurl.com/ng8zjt



    Once you are on the page, enter your information as the new owner and submit it. Often, after submitting it, you should get a confirmation of it was successful. If not, wait till you get an e-mail and allow at least 1 to 2 days. After that, you may try to contact Dell again to see if the transfer was successful to request the password reset.

  • Rodie Nov 23, 2010

    thanks you. the password really has to be reset with the help of the temp password from Dell which require ownership verification.

Hello.

Some manufacturers use a backdoor BIOS password for their tech support.

Try the password "Dell" (without quotes).

Hope this resolves your problem.

Hi:
If there are any passwords in the bios, then they were set by the previous owner, the way to remove all passwords in to remove the CMOS Backkup battery in the unit, this will involve opening the unit and removing the battery. After removing the battery turn the unit on you will get a date and time CMOS error in which at this time the all passwords are erased, Turn off the unit and replace the battery back close the unit and your problem is solved. You will have to reset the date and time settings in the bios.

    I am sorry, I have no more idea from my end. Actually Dell should help you but I am not sure why they didn't. The main problem they would insist you is the proof of purchase, if you have all the documents related to the purchase, then they will definitely help you. There is only one and only one unique password, so it'll never work unless you get the correct code. And most of all, that password is only with Dell. Yes of course many tools like Bios/Cmos password could crack them, but not always 100% and they only use random attacks not the unique code. The bios password generator does the same, the only difference is the method, one use .bat file while the other use something like a key generator with with service tag.





    It's also possible to unlock the from the motherboard, resetting the cmos chip or other eeprom modules, but honestly I have no idea with this model and there seem no one has ever tried that way. To do this, you have to be a pro IC/Chip fitter and you should know all the numbers of the chips/modules.





    These are the things that I could share, i am sorry that I can't help you further to resolve this issue. All the best.



    Once again, Thank you for using FixYa.

The technique used by experts is mentioned at this site.

Be mindful of any risks in putting back the covers etc as laptops can be very miniature and sensitive.

Hope this helps.

The Dell Latitude D620 Notebook PC has a CMOS battery.

Coin-Cell 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,

http://support.dell.com/support/edocs/systems/latd620/en/SM/index.htm

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)

http://support.dell.com/support/edocs/systems/latd620/en/SM/hinge.htm#wp1111212


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,

    Either other forums are full of beans, or you misinterpreted what was stated. It isn't a Master Password. When you install Windows, there are hash values assigned to various major hardware components in the computer. Think of them as serial numbers, but no personal information is attached. (According to Microsoft, anyway) Some of the major hardware components are; Processor, Ram Memory, Harddrive, motherboard chipset, graphics chipset, and BIOS program and version. THIS, is what makes THE Windows put on THAT computer unique. A Master Password can only be granted by Acer, and it will be through an authorized dealer, or repair shop. (NO, I do not care for Acer Support, but the above is Standard for all computer manufacturers. THE computer manufacturer grants the Master Password. It is used by the authorized entity ONLY once, and you don't receive it. You are allowed to reset, or disable the password by the authorized entity. Requires Proof of purchase, Identification, and a few $$$$. Otherwise any thief could steal a computer, and use a Master Password) Those who post 'Master Passwords', as you indicate, are posting illegal Product Keys, and are being dealt with. What Genuine New copy of Windows are you trying to install?

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.

    Good luck. I've been working on Dell's for almost 20 years and I can tell you, Dell doesn't set any master password that would protect anything a user could service. In the areas where they do use a Master password they would not allow or authorize the release of that password. If they did then Dell Customer Service would be able to provide for free. Best of luck.

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, etc.
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.

OR
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.

Dell usually sets a default password as password or admin Try those first. If no luck go into the bios setup by continually tapping the exc key while the computer boots. If your licky you may be able to set yourself as administrator and give yourself admin rights. With admin rights you can do anything.
