    Bios ADMIN or WINDOWS VISTA admin PW? BIOS or windows/ which.
    no locked up screen shots posted, and not full model number posted and no OS told. VISTA
    I wild guess at this PC,
    2008 Dellâ„¢ Studio 1735, PP31L (ell) laptop,. see the 1735 there, not told
    is this BIOS ADMIN or WINDOWS VISTA login screen locked? I can not guess, blind.
    BIOS ADMIN (backdoor PW acts like this:
    hitting enter 3 times do you get the admin secret code on the screen from BIOS. Crude black screen)
    ?????
    A PC this old , you will have huge problems, if the CMOS battery is dead or below 2.9vdc (falling fast)
    will lcause BIOS ERRORS max.(chaos with lost BIOS setting and or PW setwrong)
    Did you forget the PW, not told , or kids did this or bought PC like this. please tell this history.
    or BIOS screen PW locked
    as in:

    or OUT OF THE BLUE it started, this, (CMOS battery dead)

    there are other PWs on PC this error too. a short list, post a photo of your failing screen.
    power on PW
    BIOS Admin (if this is known we can fix the next one user easy, as the master)
    BIOS user
    HDD PW , hopeless to hack only erase and start over new OS.
    windows PW (easy fix ask... if windows login fails. say so first)
    and online email PW and vast others amazon and more but I am sure not you, this but is in my list)

    for the Back door Pw try here (hit enter 3 times see PW clue to gain secret reset PW) (hopeless new PCs)
    https://bios-pw.org/

    some can be reset with RTC CMOS battery pulled, only on the most old PC do this.

    some web sites promise a code, for like $15 and money back if fails.

    the RTC COIN cell CMOS battery for NVRAM is no good. at 3 years old
    it can not be ignored, this battery PC will play all day long with HUGE PC BATTERY removed on AC power only.
    the coin cell is due, BIG TIME. NOW, if that old. only you know age, if not bought USED PC not told.
    ask as Dell.com too, but most times now, they will not help much, they may ask for proof of ownership, hard to do.

    post a photo of your failed screen, shoot a photos with Cell phone'
    the post it below under comment , say here it is and click image ICON below.

    the service manual covers the COIN, it is even titled as that
    here
    https://downloads.dell.com/manuals/all-p...


    free manual from dell.
    it looks like Pigs tailed, RTC battery, that has 2 wires and plug and easy to find and buy on ebay.
    all that are pig tailed and CR2032 inside work , red wire is plus polarity on all.

    WE CAN NOT GUESS HISTORY OF ANY PC (BIOS ADMIN PROBLEMS)
    Bought it like this? dead. locked.
    you set the PW and forget it?
    kids got to and use did the evil act?
    or just out of the blue just now , never before it ask for PC, show photos of your screen failing? below link posted?
    on some dells this old it has backdoor PW (admin) hit enter 3 times to see an old PW reset code?
    and the coin cell must be checked for sure any PC this old.

    each dell series , year (2008 here) AND MODELS AND SUB MODELS WILL HAVE DIFFERENT WAYS TO RESeT BIOS PW. (if not TPM locked that is, TPM is magic hard nut security chip and feature do not turn it on is best

    the PW is so strict in you case that all bios HOT KEYS ,WILL BE DEAD AND ONLY GAIN YOU THE
    password locked question small window.... this is Admin locked. (best is never use this unless work for CIA.
    the problem is Dell will not help now, back in say 2009 yes, but now with zero purchase receipts.
    the classic history of this problem is complex but here is a macro list of history
    most PC deskops have jumper for Pw_CLR. not laptops.

    1: remove coin cell battery, (a new one is necessary later, and NVRAM resets PW. (many old PCs do this)
    2: then EEPROM PC dedicated chip stored. th back door PW can work.
    3: later they only allow burning this chip( programmer eeprom) with a new BIN file (binary ROM)
    4: and last TPM clocked, this needs new mother board or direct DELL intervention. to cure it (a burn file)

    the hope for you is back door PW , built in to the PC, hit enter 3 times to see the hint in the box. popup
    if you see that be happy as there is a cure.

    as you can see each year gets progressively more difficult, avoid using any BIOS PW. or the whole PC and all data you held is gone. for sure not turn on TPM in BIOS if seen ,



    and last of all, you never said BIOS nor windows PW

    when posting about PW show your locked screen we can not see now. so we can see what PW CLASS it is.

    good luck recovering your PC.

    at this screen locked, hit enter 3 times top see a hint (if lucky)

    and last and best
    1: new coin cell battery
    2: contact this PRO on EBAY go there click contact tell him your service tag,
    i see it has 1735 there


    at a cost of $2 , how can you beat his price. and help. ( get not one dime to say this ok?)
    https://www.ebay.com/itm/BIOS-PASSWORD-f...

    this is advice. only mine, do not short CHIPS out as a solution or risk bricking the PC forever
    Do not complain if a hack fails (back door PW)
    as no 2 PC made are the same, ever,. (unless is exactly and in sAME COUNTRY )
    if one service provider fail try others.

    and do not use PW admin locks ever, and not NOT BE IN THE PICKLE JAR.
    this PW stuff is a double edged sword
    1: edge 1, is hard nut security , DOD,DOD,CIA,NAS, and the like they must use it but not you.
    2: edge 2, lost all your data you did, join the COULD YET?

    on new PC 2020 up and UEFI locked as most or all are, there is no cure, (sword 2)
    only you can protect your self using external to PC backup or use the cloud

    that is it on my pw, page
    see 6 levels here.
    https://pcdied.com/passwords.html

    and cures, and for sure no 100% cures on all types of lockouts, nobody has that.

    above is not windows local at all (it is live cloud locked and easy to reset at live.com .)
    local accounts only PC we hack that easy too. not told OS, (VISTA) above is w10, live.

    Larry Ng Sep 29, 2021

    OP I can not see your screen at all there are over 7 levels of Password blocks (access) on PC.
    even fingerprint readers and more,
    above is windows 10 login, for local, or on line live.com account.
    the windows cures are easy , unlike BIOS.
    best is to use your working call phone and take a photo of any failing screen then post it here.
    add image below ICON
    edit that photo if your email is there, like this [email protected], I use PC paint to do that, easy as pie.

  • Anonymous Oct 02, 2021

    "locked by the administrator"
    post a photo of failing screens please, no better way on earth (in the blind here) works better.
    I must see your screen.

    NO screen posted
    bios PW? or HDD PW or windows? what?
    is this windows 10>?
    did the PW get forgotten by ken folk or you?
    did you buy it like that, locked
    did the PC never do that ever, but just not out of the blue ask for PW?
    history and context matters on PC, big time and for PW (huge)
    https://pcdied.com/passwords.html

    the 6 layers of PW, not counting OMG< finger print readers, or MS HELLO.
    NO OS told windows 10? not counting the DOOM of TPM turned on,(I call this CIA mode)

    this is your coin cell, not one lasted 13 years, we replace it first.
    if dead or below 2.9vdc it is bad,
    and if dead, the BIOS will Lie to you about 64 times (1/2 of 128 bits set wrong) lie like a dog it will
    CMOS means battery powered NVRAM. and is BIOS settings storage, and must never be bad.
    and never ever trust any BIOS lies with a dead coin or go crazy or broke fast guessing wrong.
    $1 coin, at walmart exit lane 15 get one. put it in and reset BIOS if it lets you.
    the big battery is bad to this old and if shorts it may catch fire,so remove it from the home (far)
    12 steps. for the reset. for all PCs. (not counting Laptop plastic cover pulls)https://pcdied.com/cmos.html#lapcoin

    this is YOUR MOBO !! see it ?

I forgot my Password of my Dell Laptop. I candidati not get on. I have face recognition and my username in FassAccess. Can I get help?

Larry NG and JonSnell are right, so you have few options.

One method is to try as many passwords as you can think of, since unfortunately, many people re-use the same passwords for different purposes.

The Dell website has a Contact option for help, but as they advised you here already, that may not give you a good option. They may want to know more information than you provided here. What model Dell is it, for example?

My laptop ask me primary or administrator password what shall i do to opperate my laptop?

Your laptop is password protected: in order to use it, you need to know a valid userid and passord.
- Primary password: your assigned userid and password (which could just be blank - press enter after entering userid)
- Administration password: enter admistrator userid (such as as administrator or Admin) and the assisgned password (whih could be admin) - Admistrator can override a user locked laptop.
Turning the power off to the laptop will reset the laptop to 'normal' usage but may still require a userid and password.
Hope it helps.

Always first check to see if your CAPS lock light and or your Number lock lights are on. Try your password again with the CAPS off and on the numlock on. If that doesn't work you may have had those buttons on or off when you originally typed in the password so try it in different ways also.

Breaking a pasword in XP is possible with the right software but not easy.
