BIOS Master Password

Laptop BIOS Master Password Generator

If you need your Laptop BIOS Password Reset, then you’ve come to the right place. The Laptop BIOS Master Password Generator reveals the password for many popular laptops. Not all laptops are vulnerable but many are – give it a try, it’s free.

For late model HP laptop owners we offer a guaranteed solution

Achieve Laptop BIOS Password Reset on HP, Compaq, Dell, Lenovo, Sony, Samsung, Acer, Asus, Lenovo & Fujitsu & more brand name laptops with the Laptop BIOS Master Password Generator!

Those manufacturers listed above – your BIOS is brake. All your password are belong to us. (Well, nearly all.)

8-digit BIOS provided by Insyde H20 and 5-digit Phoenix BIOS are also pwnd.

Hewlett-Packard (HP) laptop owners – if the Master Password Generator can’t solve your problem, we now offer a guaranteed solution. Confirmed working for all HP laptops 2012 & newer, except X360 & X2 models. HP Envy, Omen, Spectre, ZBook, Elite, Pro, Folio & every other range are vulnerable to this method.

Seen this before? Bios-locked & password lost, that’s what that screen indicates.  But the 20-digit machine ID code displayed can often be decrypted to reveal the BIOS password. (That code reveals a Fujitsu-Siemens laptop with password 9538393)

BIOS Master Password

When you open a laptop & find yourself faced with the immediate black BIOS password screen & absolutely no idea of what password you used, all you gotta do is come to this page @

Many HP/Compaq, Dell, Lenovo, Sony, Samsung, Acer, Asus, Lenovo or Fujitsu laptop BIOS passwords can be revealed.

Hints & Tips

In the case of Asus laptops it’s the date code you require – enter an incorrect password then press Alt +R at the next prompt. Take that date & enter it in the BIOS Master Password Generator below in the same order (yyyy-dd-mm or dd-mm-yyyy) as displayed on your Asus laptop.
If your laptop has an Insyde H20 BIOS, then your secret sauce is to use a USB keyboard to enter the master password generated here.
HP EliteBook/ProBook
For Elitebook & ProBook (up to 2014) there is an alternative method available here in the downloads section. Highly effective on vulnerable machines, full instructions included.
Late Model HP
Envy, Omen, Spectre, ZBook, Elite, Pro, Folio & more can access our premier guaranteed solution. Confirmed working 100% on all current HP laptops except X360 & X2.
After entering the password in Dell laptops, press & hold the left Ctrl key then hit Enter twice.  Some Dell service tags are missing a suffix – first try the password generated, then try the passwords for all suffices by adding either -595B, -2A7B, -D35B, -1F66 or -6FF1 to your service tag. Downgrading your BIOS can change your suffix, resulting in a successful password generation.
For the later 6×4 password implementation, download & install Python 2.7 (available for all platforms), then grab the Fujitsu 6×4 Python script & run it. All done.
If your response code pattern is 4 x 4, then it’s a one-time password, generated fresh each boot. Do not turn the laptop off after obtaining the Challenge Code as the Master Password is specific to that code. Restarting before the password is entered will require a new Master Password.
List of Vulnerable BIOS
Compaq 5 decimal digits, 10 characters Dell bios code ending with -595B, -D35B, -2A7B, -1D3B, -1F66 & -6FF1, also with no suffix. Fujitsu-Siemens 5 decimal digits, 8 hexadecimal digits, 5×4 hexadecimal digits, 5×4 decimal digits Hewlett-Packard 5 decimal digits, 10 characters Insyde H20 8 decimal digits Phoenix 5 decimal digits Sony 7 digit serial number, 4 x 4 one-time Samsung 12 hexadecimal digits Asus Date code

Anyway, whichever BIOS-locked laptop you have, grab the Machine ID Code - sometimes called the Service Tag, Challenge Code or Response Code  - usually displayed after submitting a few (3-5) incorrect codes - that’s the unique identifier we need. Pay special attention when reading the code, be careful not to confuse I & l or O & 0, B & 8, S & 5.

Now enter that code in the box below, hit the Crack It button.... Ka-ching!! No surveys to fill out, no pop-under pR0n adverts, just pure goodness & quite likely your Laptop BIOS Master Password too.

When you've done your Laptop BIOS Master Password Reset, please leave a comment, send a tweet, or do whatever peeps do on Facebook to tell the wwworld about your win...

  1. Thanks for Ctrl+doubleEnter info for Dell – it helps for Inspiron 5558 BIOS pwd crack! 😀

  2. Hi guys, Thank you very much for your hard work to create this tool. Unfortunately it’s not working for me. Could you provide working password for: GG87762-6FF1

    1. The issued response will be correct. The key to success is to hold your Ctrl key when entering the code, then press enter twice.

    1. The challenge code should be programmatically generated on-screen, it’s not a hardware feature.


  4. Latitude 7490 — 8RQSHM2-6FF1 — Dell Security Manager. Codes didn’t work. Any thoughts or suggestions?

  5. I have a 2017 dell inspirion service tag #52h07f2 i need a hdd reset passcode for my laptop help please

  9. Hi, I have an Acer laptop that’s BIOS locked – it’s giving a 10 digit unlock password of 1706266768

  10. Can you please give me a reset code for my Acer Swift 3 notebook? The bios code is 1903742341

    I tried all the generators but nothing works.

    Thank you for your support!

  11. I don’t understand, i tried with all codes from specific date, changed also A with Q, all with external keyboard in case of capslock problems.. and password is always invalid /ASUS

    1. Try taking 10 years off your date code Tibor. If the code is xx/xx/2018, then enter xx/xx/2008 & use the master password provided.

  12. How about Lenovo Thinkpad T430 NO challenge code at all.Just a stop sign, then power down. A bar code under the battery is all I have. : TYPE 2349-GP6 S/N PB-1HPEZ 13/05
    Can you help me?

    1. Lenovo BIOS has so many twists & turns. That padlock symbol indicates which level of lock you’ve got. Your best solution is to dump the bios with an SPI reader, decrypt, remove the password & re-flash. You’ll get quality guidance from the peeps @ &

  13. Owwww yeah !!!

    I have a very old Dell Latitude X1 that got stuck with the dreaded system password needed message.

    I entered the serial number in the code field and it gave me a couple of passwords.

    The second one was the good one !!!

    I entered the BIOS and disabled the system password so it would not bother me anymore.

    Thank you ! Thank you !

  14. Não consegui resolver o problema do meu setup, a senha que aparece depois de eu ter inserido os 18 digitos, vem systema não aberto…

    1. Josh, hard drive passwords are specific to the laptop that they were originally locked with. Without that laptop, I’m not aware of any recovery available.

  15. I have the dell latitude 7490 and its stuck on dell security manager page when i turn it on. None of the codes work and there us very important stuff on my laptop please help

    1. Hi Katie, did you hold the Ctrl key & press Enter twice? That’s caught many people out. If that didn’t work, try flashing a different BIOS firmware, download from Dell Support. That’ll give you a new System ID code that we can generate the master password for.

  16. Hi
    I used this free password generator. It’s gives master passwords but password is not working.
    My Dell latitude E5500 code is 1R8LD4J-1F5A

    1. Miles, straight up, click the link, it’s $40 for a guaranteed solution. Your HP 15 will be password-free or your money back. (We’ve never had to refund yet.)

  17. Hi I have acer aspire 315 21 26a9 i tried your code didnt work why does it come up as a dell when its acer thank you im dyng here key is 1150855415

  18. Hi I have acer aspire 315 21 26a9 i tried your code didnt work why does it come up as a dell when its acer thank you im dyng here


  20. Dell Precision service tag 71MLYN1-1F5A, any code working? the generate didnt work for me

    1. The solution for 1F5A bios to override master password on Precision M4500 is to downgrade the BIOS using this method:
      Download M4500P02.exe BIOS update from Dell Support, then use this CMD to create .HDR file “M4500P02.exe /writehdrfile”.
      Now copy M4500P02.hdr to a USB flash drive. Shut down, remove battery and power from your Precision M4500, connect the flash drive.
      Hold END key while you plug in power cord and release END when the battery LED light comes on.
      If the LED light blinks red/blue it’ll be flashing successfully – wait till the laptop restarts.
      Now you have downgraded your BIOS and the 1F5A should be changed to 2A7B / 1F66 – the online generator will work.
      (When you type the master password, hold RIGHT CTRL, then ENTER twice.)
      I used M4500P02.exe as an example because it’s the earliest BIOS file for M4500, there are other BIOS updates available. All you’re looking for is to change your 1F5A suffix.

  21. Supervisor…no option to change something in bios..but boot option is can be installed,

  22. Hi,do you have an option for Lenovo Thinkpad Carbon x1 5th.generation

    1. There’s several levels of UEFI password on X1 laptops. Is yours Power On, Supervisor, User or Hard Drive?

  23. Need help with dell inspiron 15 system disable 3AC535C18F483011 AND SERVICE TAG BRP5602

    1. Did you try the Service Tag responses?

    1. The algorithm works, it can only be input. If you’ve already held the left Ctrl key while entering (& pressed Enter twice) then try it with the right Ctrl key. Failing that, grab hold of a USB keyboard & try again with that.
      I’m going to email you on a separate subject, you may be able to help me.

  32. Is this generator down right now or no longer work? Doesn’t do anything after i put the code in and hit the button

    1. What kit are you using, John? I just tried it from Chrome & Brave from my Galaxy S9. Works for me.

  33. I have an HDD S/N A1022087 and Service Tag: CV28MP1. Please can anyone help me with the Password. It’s a Dell Inspiron Laptop

    1. Some Dell service tags are missing a suffix – just try the passwords for all suffices by adding either -595B, -2A7B, -D35B, -1F66 or -6FF1 to your service tag.

  34. It worked for me but i forgot to disable the administrator password. I restarted my laptop and now the administrator lock is back. How the hell could this happen?

  35. yahoooo, worked like a charm…you are DA MAN !!, thx again…will definitely use your HP guaranteed solution if needed 🙂

  36. Hi Megabyte, tried to do a dell(1QVLM32-1F66), but your gen is not working, nothing comes as result. It worked for me in the past a couple times, thanks for your awesome solution anyway but did you update your code again? 🙂 (tried edge and FF)

    1. Hey thanks for the heads-up. I’m still not sure exactly what caused that, my suspicion is the Cloudflare caching rules that I created yesterday. Anyways, it’s fixed & doing what it does – generating BIOS Master Passwords.

  37. Hi, I tried for 7N18QQ2-BF97, but nothing found on your site. please if you can help. many thanks.

    1. 36833275 – please note, this is a one-time password. If you’ve rebooted your Vaio since posting your challenge code then it will have a new challenge code now & you’ll need to visit the Master Password Generator again.

  38. Fujitsu Celsius have 6×4 decimal numbers ,can’t create Master password. Please someone help me

  44. I got the code i 63229772. I can’t seem to figure out how to do this unlock thing. Can some one please help

  45. Hey, this worked!! Thanks so much! I tried from a different site a million times, which gave the same code, but for some reason it only worked when i used the code from your site. LOL!! Thanks!! you guys rock!! Dell E7270

  46. Hello, i have tried the code generated for my acer aspire a515-41g with the code 1747859934 but it is not working. I have pressed left ctrl, right ctrl as instructed, still is not working. Can you please further assist?

  48. I have a toshiba tecra m11-10e laptop bios password , i dont know how, suddenly its asking bios password . now i cant enter the windows ,how to break the bios password

  49. I have a 2015 hp, I purchased from auction, has admin or power password. There is no way I would pay for this “guaranteed solution” when there is nothing usable for any other computers here.

    1. Ericka – displaying her inability to read comments.
      I’m actually quite happy not doing business with you & knowing that your HP remains useless. So far today I’ve taken 10 HP UEFI solution orders & not once have I ever had to issue a refund. My solution works, your laptop doesn’t.

  50. Hello!

    many times I typed wrong bios password, so the bios of Acer Aspire V5-471G notebook has blocked. I tried many web link bios master password generator (for yours too), but didn’t work.
    I disassambled my notebook and under the RAMs two pins I connected 20-30 sec. G2201 BIOS password reset, G2101 and G2701 power button. It’s didn’t work too.
    The BIOS of the notebook is Phoenix securecore BIOS.
    Please help me.
    The bios system locked code is at the moment D662ABB3
    sorry my english…

  51. Hello.
    Have an Acer Aspire A114-31 notebook and was forget bios password. Can boot from internal hard drive but cannot from usb or sd due to disabled functions. Code I get is: 1536031184. With generated unlock key I cannot do much as it is NOT correct.
    Can You please help about that?
    Thank You

  52. I have a Dell Inspiron 15, the model number is 3521-6024, the service tag is CH36GW1. I have tried putting the service tag in the generator but nothing happens. Please help, I have been struggling for days with this.

    1. In the case of newer UEFI Dell laptops, your best bet is to contact Dell Support – they’re very helpful in situations like this.

  53. I am from india, i am having sony vpceh3aen laptop .which was locked bios from two years but it was working normally because i did not tried 3rd time and today i tried it my password is cracked with this site .i am very thankful to this website owner again thank you my english is poor

  54. The Button is not working for me. I have a Dell Servic tag DX64QY1 When I hit generate nothing happens.

    1. That’s because the Master Password Generator only supports Dell laptops with 7-digit code plus one of the following suffixes: -595B -D35B -2A7B -1D3B -1F66 & -6FF1

      If your system does not provide that type of System ID, all I can suggest is that you try official Dell Support, they are pretty good to deal with.

    1. Sorry, I haven’t got that algorithm, I don’t know anyone that does. You could always try Dell Support, they’re quite good to deal with.

  55. He’s referring to the “Crack” button on your webpage. It’s doing the same thing to me. Click and nothing happens. I’m going to try to update my Java and see if that helps.

  56. Thank you very much.Sony Vaio has reset the Notebook bios.
    I would also recommend your site to my friends.

  57. Hi there, I have an Acer Swift SF315-51 which produces a 10-digit numeric unlock key after 3 failed attempts. I’ve tried entering it with ctr+enter, I made sure to try using all forms of letters (l vs L, 0 vs o) but nothing works, it this because the algorithm only cracks 8 digit acer passwords?

  58. I thought I had a pointless contribution to the huge pile of electronic waste that we’re generating until my friend showed me this website. Now I’ve got an excellent laptop for university!

  59. Thank you so much, it really belp me bypass my laptop that i found in storage. Although i did get the right pw at another website they did not give me the hint of hitting control enter. Once again thankyou for your help.

  60. Hallo ich habe eine Toshiba Satellite c670d-126 bei dem kommt kein code was kann ich da machen bitte um hilfe

    1. Hey thanks Dakota, I didn’t realise that the Asus Master Password Generator wasn’t working. After some quick keyboard action, it is now. Check it out again. Your password is 0L2LBADB

    1. Dell tell me the process for entering the generated password in your laptop is:
      Enter the generated Master Password, press Enter. If the computer responds with the message Invalid Password, press the Enter key and continue to enter the same password three more times. After the fourth attempt the BIOS should accept the master password, clear the password and allow access.

        1. Are you entering the response code exactly as it’s displayed on the Dell? I don’t recall seeing a Dell response code with lower case characters. The Master Password for the one you gave – 230r3c2-1f66 – is w9C49rRZQWJFZlf6 (3rd last is lower L), whereas if we replace the lower case letters with capitals – 230R3C2-1F66 – then we get zYkqw19iDC5313B0.

          Does that help?

          1. Yes I used lowercase it just auto currected when I pasted it here I used one that started with z

            1. You could try Dell, they will issue their own Master Password after checking ownership & user authority. Ask for their help here:

            2. Pls I really need the hp mini code for ” i 60337746″ the accepted code is 16 letter unlike the generated one here that is 18 letters… thanks

              1. It’s that empty space causing an undefined input error. Where it’s expecting a defined character, there’s an empty space. Maybe take a second look @ your HP Mini?

  61. Hi!

    Could it be possible to get the master password of a Dell Latitude E6410 please ? I try several time but never works. My Service Tag is JRDLZN1-1F5A

    Thank you very much for your help!

  62. Can I get some help please. I have a Dell Inspiron 11.
    Service Tag: 88WRC82
    Express Code: 17953011362
    Can I get some help ASAP with a working code. Ive tried calling support, and have tried all available codes even with left/right ctrl. Thanks!!!!

    1. Help is provided on this page. Use the Master Password generator. Enter the response at the BIOS password prompt. Pr0fit.

  63. Hey I have a Dell Inspiron 3542 and the service tag is short – F06ZL52. Ive tried many generators but haven’t been able to get any of the keys to work. Do you know if that model requires a left or right ctrl-enter? Any tips? Thanks much.

    1. Sorry Tom, it’s way beyond the spec of this service to provide the particular password entry nuance for each model Dell produce. Rather than the Service Code, have you found your BIOS response code, finishing like -1F66 or -1F5A or similar. Throw that into the Laptop BIOS Master Password Generator.

    1. Press & hold the Left Ctrl key. Carefully enter the BIOS master password. Keep holding Ctrl key. Press Enter. You may need to press Enter twice.

  64. Wooowwww coooooolll
    Worked for my Dell E5440 1F66 .

    Thank you guys.

    Thanks for the FREE.

    You founders of this site are not living for nothing.

    You leave something behind.

    Respect for you.

    1. Lenovo (& previously IBM) have always had solid security in place for their BIOS passwords. You’re going to need a service from Phu Hai in Vietnam – WhatsApp +84 91 872 55 97. Or visit this Ghostlyhaks forum here: join up & ask for advice.

  65. Heyyyyy help me pls, my Acer aspire 7 has a key of 10 digits, the password generator doesn’t work because it says that insydeh2o has 8 digits but I have 10. I have read another comment of a guy that has an Acer aspire also with 10 digits.. my insydeh2o version is 1.13. how to solve?

      1. Either try the methods listed in the comments or contact Acer support. I do not have the algorithm for 10-digit Acer BIOS at the moment.

  66. Hi am just doing something wrong dell #9PSHH72-6FF1 tried several times but nothing no code shows up please help

    1. Sorry about that Richie, I’m experimenting with various caching & CDN systems to improve website performance as the visitor numbers scale up. Seems like some affect site functionality negatively, & that’s no good for anyone. So no, you didn’t do anything wrong, & thank you for reporting the issue. It’s fixed now, your unlock code is FcCZmCR8ZRzzEMWS

  67. Looks like it doesn’t take codes like 2016/12/05 (as shown on ASUS screen), if entered as 2016-12-05 it gives a password but it doesn’t seem to work.

    1. Heh, that, Mike, is because here in the sunny South Pacific, way down at the end of the Internet, we do write our dates DD/MM/YYYY – the reverse of yours, which do – I must admit – make more logical sense than ours do. But anyway, play it the Kiwi way – put your date code in backwards & let’s hope you get lucky.

  68. Hi, i need to unlock ma acer travelmate P645-S, key: 67994976 leads to an generated key from your site (Same as from other sites) that doesn’t work.
    I suppose insyde/acer changed the was of generatIng the unlock key… Do you have any hint?

      1. Remove your RAM, look for 2 pads labelled G2201. Remove your laptop battery & charger connection. Hold a piece of wire firmly on both the G2201 pads. Now connect your charger & press power.

        If you don’t have immediate success, try again with a firmer connection between wire & pads. You may have to do this 5-6 times but eventually you’ll free yourself of the BIOS password.

        1. I will have a closer look. I only See jcmos, no G2201, and no other pads… Hmm. Jcmos didnt work…

          1. Look closely for 2 pads next to each other, very similar in style to the JCMOS pads. Maybe labelled JCMOS1 or RTCRST or JPW. Short those as I suggested.

  69. [I 72663069] is the code i get. Im trying to fix this hp notebook for a friend. Ty in advance

  70. Acer Aspire R3-131T-C1YF
    S/N NXG10AA005541017626600
    F2 Forgotten Password
    3 times gives gets me to Bios however can’t clear Supervisor Password

    Tried Multiple software with no luck

    MUST fix for school use

    1. Have you got the BIOS key hint? If not, Acer BIOS clears when you remove the CMOS battery, main battery, power connection & RAM, then press the power button for 15 seconds to clear any last residual bits of current. Now replace everything & you’re good to go.

  71. If you’ve got a BIOS lock, I would use the longer Dell from Serial password. If it’s merely a HDD password – you’ll know this for sure if you swap the HDD & boot successfully – then use the shorter password.

    Don’t forget to hold the right Ctrl key when you press Enter to validate the password.

    1. Well, that’s where I’m stuck….I have 3 HDD’s but they’re junk they don’t work. So worse case scenario is that I have to go and buy a new HDD. I think that’ll cure the problem! Thanks for your time Megabyte.

      1. Try booting without a hard drive, see if you get dropped into the BIOS/UEFI. You won’t do any damage. If so, it’s a HDD lock for sure & you’ve just been given the password.

        If you’re running Win10 on another laptop, that drive will just slot in & highly likely boot straight up. The other option is to download a Win10 PE .iso, use Rufus to burn it to USB & boot from that.

        (It’s not really burning, there’s no smoke)

        1. Alright, I’ll try that but the only other laptop I have belonged to my late uncle and I’m not comfortable opening it up it works and I don’t want to mess it up. I’ll let you know what I come up with going without the HDD.

    2. Ok, it definitely has a system or bios pw. But I found the only sn in the batt comp and input it into the generator and it doesn’t pop up any codes. My sn is CN-OU692R-12961-973-3277-AO1 not sure if the O’s are zeros or vice versa? It’s got windows vista as the current OS so it looks like a lost cause. Thank you for your efforts I’ll be back I want to see the generator work successfully seeing others having good luck it has to be for real. Take care

      1. James, put 96ZYRK1-2A7B into the generator. That’s your machine ID code, your master passcode is only a click away

        1. Heck ya that worked but there is a HDD pw and the one the generator gave me didn’t work but I’ll keep at it thank you so much.

          1. If it’s not the original hard drive, maybe it’s one locked by another machine, then no, the generated password won’t accept. Maybe the original drive is one of the other drives you have? Try them if you think that’s possible. Hard drives will only unlock in the laptop with which they were originally locked.

            If not, a new HDD isn’t a major expense, but for a 10-year old laptop I’m sure you can pick up a reasonably reliable used drive at your local recycling center. Scavenge 2x 2GB DDR2 RAM – that’s your biggest performance booster. Then install Ubuntu or another lightweight OS on it & you’ve done a good thing, returning old junk to life, making it useful for someone instead of useless to everyone.

            1. Honestly speaking I’m not a big fan of Ubuntu but I guess in this case I have no other choice right? It’s actually my cousins laptop given to her by her friend who passed away and that’s the reason for the password dilemma. Anyways I am a believer in your generator it worked awesomely. Now if I can get past iOS heh heh, I’d be in trouble. Lol have a good night and once again thank you a million.

  72. Does your code generator work for Dell Latitude E6400 96ZYRK1-2A7B is the service tag number on the system/admin password entry white screen. Or would that be a HDD password? Thanks, James

  73. please please help ,
    i have a proof of purchase of laptop fujitsu lifebook AH531
    I forgot my bios password ,I can’t boot can you please help ?

    1. Richard, Vaio VGN uses the notorious 4×4 pattern one-time BIOS code where the 4×4 code changes each reboot – hence the one-time reference.
      Go ahead, grab the 16 digits showing on your errant laptop screen & enter them into the BIOS Master Password Generator. Click the Crack It button & you’ll have your answer.
      If you are doing this remotely, make sure the Vaio doesn’t shut down between you taking the 4×4 code & entering the master password.

  74. my Acer Aspire 3 model A315-31-C8PH, wich Key: 1838835523, the code generated is not work.

  76. Yes! It worked! God, I have been trying to solve this problem for days. I have a Dell Latitude E7440. My code ended in 6FF1 and I used the ‘Dell from serial number’ password that this page generated. I entered the password and then pressed left-control and enter. BINGO!

    1. Hi Steve, bugger, I was doing some updating on that page this morning, must have forked something up. I just tried it with Chrome on my iPad though, here’s your code – S8EME9kKDUMUVqof

  79. You are the best for a dell 6FF1 I have entered the “Dell from serial number” field password and pressed left CTRL and ENTER (not the OK button)
    P.S. the Service Key that you enter is case sensitive !!!

    Where can we donate?

    1. That’s because you’re 1 digit short of a Dell passcode. 7 characters + suffix gets you there

  81. I actually cant open my dell xps 12 9Q23 i tried the provided passwords and did press right ctrl and enter to enter the available passwords but it didnt work please help asap

  82. I just ran a Dell 6FF1 UEFI successfully, B02HMC2-6FF1 was the Asset Code, master password response generated fz0Ibn3vHw321fNs – which is correct.

    Two points to consider: the 4th character is an upper case i – not lower l, & even if you have entered the password correctly, you still need to hold the right-side Ctrl key when you press Enter.

    1. Did you press the right Ctrl key when you hit the Enter key? That’s a required action for some Dell BIOS passwords.

    1. Hi John, it’s not so much the laptop manufacturer that’s relevant here, it’s the bios provider who is targeted.

      Award bios is used by several laptop manufacturers, for example. Award own Phoenix, there’s also Insyde & AMI brand bios too. Very rarely do the manufacturers write their own custom bios. Even if the bios is self-branded, there’s a high likelihood of simple rebranding going on.

      If your (insert brand name here) laptop has a bios that reports back with a challenge code – This Laptop XYZ123456 Is Locked – or similar, then you know that the possibility of decoding the password exists.

      I don’t have a Toshiba laptop & I’m not certain who makes the bios in those models you mention.

      My best suggestion is to give it a go, it’s free to use & I’d be interested to know the answer too.

      Cheers, thanks for stopping by

  83. I’ve updated the decrypting JavaScript to include later model laptops today. It’s still a case of “some, not all” but this solution does cover the majority of brand name laptop manufacturers – Dell, HP, Sony, Acer, Samsung etc, and now includes their late model products too.

  84. Is not working. Button not even respond. Stupid button… Okay I make joke, that was joke. Is a nice button.

    Can you help with fix or workaround? Maybe I do something wrong, but still I get no error code.

    I enter my challenge code: AL2MY-N48VX-2TD8G-JH4UH-KCG5K

    1. What brand of laptop is giving you that response code?

      As it says up the top of the page – for some, not all laptops. Maybe (sadly) this is not one that the decryptor works on.

  85. So like my boyfriend says “no, that laptop is f**ked” and I think “I’m gonna go ask Megabyte” and I don’t even ask, I just use this page. I put the code numbers and letters in then click Crack It and Yis! it worked!! And all my posse are going “Yis, girl power!” and now I am l337 haXx0r!
