- This is how you remove the bios password if you don't know it.
This should work on most if not all ProBook, EliteBook, ZBook models.
HP used to generate and provide a unique SMC.bin file that you could put on a USB and use to remove the password, but they no longer do this and tell you to go buy a new laptop and say they cannot help you.

OMG..dude. I've been doing IT for a long time. You blew my mind with this. Since I'm a nerd I found this fascinating, but aside from that I never thought to do something like this. Where did you even acquire the knowledge to flash the BIOS chip from?
Also, it was a bit disappointing that you seemed to skim over the area where you put the pads down for re-soldering the chip on the board. Even a layman knowing about flux can de-solder a chip, but re-soldering is where having skill comes in. Having a demonstration would have really helped since I think anybody even considering doing this would probably not be in your part of town to have you do it.
Iv done a lot of ModChips and that type of work so flashing and editing bios it’s pretty easy with the right tools. Check out my TikTok I post on there mainly.
Excellent video. Removed no problem admin password from my HP Elite Book 8560p, but most settings are greyed out: admin tools, update sys bios, disk sanitizer, sys configuration, boot options, ...etc
Set a new password. Then you can remove it normally and they will become enabled.
Also try reset bios to factory default also works most times.
@@CoolshrimpModz BINGO this worked, Thank you. Updated bios to latest version.
Tthanks! Worked with HP Zbook 14 G2, bios version 1.28, rescued from a dumpster.
Nice work
Excellent video my friend. As a PC Technician it has been a challenge to remove BIOS passwords from especially laptops. Please tell me the names of the tools I would need in order to achieve what you achieved. Thanks.
Usually a soldering iron/heat wand. And a eeprom programer for reading and writing the chip. Link to some in description just see what chips you normally need to work with and see if there supported by programmer.
@@CoolshrimpModz Cool bro. Thanks for informing me. I appreciate it.
You rock! I was able to remove the BIOS password on my Elitebook 2760p!
great video
i have hp zbook power g8 can i reset the bios pass without soldering and which programmer should i use
thanks in advance for your time
That is awsome!
Does this work for "HP Zbook Fury 15 G8"? Or is there another way to reset/remove bios-password?
Successfully did this to a ZBook 15 G2 using the SPI interface on a Raspberry Pi and flashtool! Searching for 'SPI EEPROM Dump with raspberry pi flashtool' should dig up instructions.
Notes: Could not do it with the chip on the board (via soldered wires), had to desolder and remove the chip and connect to the Pi directly. Obviously something on the motherboard corrupts the SPI signals.
The address was different in my hex file. Found the right address by searching for 00 42 00 49 00 4F 00 53 00 20 00 41 00 64 00 6D 00 69 00 6E 00 69 00 73. The dot before the U is actually AA not 00 and this did not show up as a dot in HxD (the editor I use). So instead of aiming for a dot, a better description is: "zero everything up to the pattern AA 55 7F 00".
Reflashed, resoldered and got straight into BIOS! Thankyou for the video!
It looks absolutely smart (& cool)! 👍
One question: would it be ok if I use a WSON-8 probe to read/flash the chip in question (mine is a Winbond 25Q256JVEC), instead of desoldering/re-soldering the chip? Thanks a lot for the tips!
Yes you can try a clip or probe it does work on many, but note some won’t allow for ISP (in system programming).
You do a great job at making the video and explaining. 2 thumbs up
Thanks
Awesome video. I came back to type out the BIOS password you cleared as I don't have the technical ability to handle hardware components, but I did not see reasonable strings to copy, can you help by sharing the original BIOS password you cleared?
I do not know the original password as it was set by a user, this is why we do this process it clears the password and returns it to be blank. after that you can set the password to whatever you like.
Nice video bro, one question tho.
Can't I just replace the entire bios chip? Won't that be cheaper than buying tge tools
Yes it is and is just as good.
@@CoolshrimpModz thanks mate, I subscribed!
Intresting. I have probook 4520s but haven't really located bios chip so i can try this.
Great video. Thanks!
Any chance to do this job without unsoldering / removing the bios chip?
I am not the best in soldering. (I have to do it on a HP ProBook 4530s.)
Only one other option you can try but I haven’t tried on your model. You need to short 2 pins on bios chip.
superuser.com/questions/1108228/remove-bios-password-for-hp-probook-4530s-reset-bios
If this doesn’t work then you will have to edit/replace bios chip. As they no longer provide the smc.bin file to reset the easy way.
@@CoolshrimpModz, thanks a lot! :) I tried the other way already, without result yet. Maybe i have to do repeat multiple times.
HP s#x this way, as they want to change and charge for a whole new motherboard. :(
@@axelh.7690 ok yes HP used to provide a file but they no longer do, and if you pay they simply replace the whole board or they use the smc.bin internally and tell you they replaced it but we can’t know for sure. They don’t simply replace the bios chip as they don’t do component level repairs.
Brilliant Video, Many Thanks
Excellent Tutorial
This same procedure is used to bypass locks on macbooks. But keep in mind it is only a bypass on the macbook.. not a permanent solution. BTW, I am curious how you didn't melt the bottom plastic around where you used the hot air.
He kept the heat gun moving. The plastic underneath is not as thin as paper. Had to edit this reply...The BIOS chip is connected to the circuit board (MOBO) which is made out of fiberglass and copper. It can scorch but not really melt unless you are determined to melt it.
No need to read twice and compare. Read once and just use the verify button. It will read it second time and compare it to the first read.
Your right. But at least with read twice you have 2 physical files saved. Incase you edit your original by accident you have a second original.
@@CoolshrimpModz True, good point. And by the way, this exact method works only up to 840 G2 and other series with similar release date (2014-2015 I guess). After that G3 and G4 use a different keyword and G5 and later need EC bios, not main bios, modified and again use a different keyword.

REALY REALY thanks ,Great job , you made my work very easy by this methode
Great ! Do you think it would work on HP EliteBook g10 ?
Can you share compare bat file ? Also, on 470 G1, i can't find the administrator password in the bin file... Is there another to look for than "BiosUser00" ? Thanks in advance and sorry for my bad english !
Damn it I was really hoping to find a way to do this but apparently I'm just not going to be able to. Well time to take apart these laptops and sell them for parts........ Great video though.
For clarification I don't have one of those reprogrammers. I'm just a small guy that buys recycled laptops.
I have a question: I have hp elitebook 850 g5 and i too do not know the admin bios pass. When i try and guess the default or whatnot i get i think 3 or 4 tries before i get an error lock msg. But i can still reboot and get into windows. Moreover i bought this laptop from a friend, and neither I or my friend had created this password. So my question is, is there another way to change the password through windows or command prompt? Also, great video. I wish I had the know-how and as much knowledge as you to set up my system, and fix problems such as these. Thank you.
Doing what I did In this video is the only way to remove the bios passwords on most current laptops. You cannot do it thru command prompt like some old models.
Hello, will this work on probook 6450b? And is it possible to do something like this without removing the chip and the motherboard?
Yes should work the same across most Probook models.
But you will have to unsolder and reprogram the bios chip.
There is no software only method like (SMC.bin) as they are no longer avaliable from HP.
Hello I love your videos they are so easy to follow. I just have a quick question, I am going to buy a programmer and would like to know if the program that you use comes with the programmer or do I have to purchase the software separate. thank you
The program for read/write itself is free (FlyPRO) and can download it off the programmer manufactures site. The one I’m using is a pretty cheap programmer. But can do many chips.
@@CoolshrimpModz what is the programmer you used?

Can I use Organizer SOIC8 SOP8 Flash Chip IC Test Clips Socket Adpter Programmer BIOS + CH341A 24 25 Series EEPROM Flash BIOS USB Programmer Module (Double Clip+ USB) . These are the ones being sold on Amazon but it doesn't look like yours? What is the exact make and model # of your programmer?
ch341 can only flash 3.3vdc chips it cannot flash below that voltage, so make sure that your chip is 3.3v supply by testing the voltage accross gnd and vcc.
Do you offer this solution meaning how much would you charge for it?
Yes I do depends on models. Message Me.
Do you have any idea of how to remove Computrace from a laptop?
Using this method once you have admin access you can disable it.
You can also lookup your motherboard chip listing and locate the computrace chip... some it is actually the tpm chip, so if you replace that along with a bios chip then you can clear everything and permanently disable computrace.... there is a CZcams video on how to do that
Would you happen to know where the bios chip is on a hp zbook 17 g3?
Hello dear sir, Thank you very much for sharing your knowledge. This solved my issue perfectly!! I had problem with writing to MX25L6406E chip (EZP2019+ programmer) so I pushed down speed to 1.5MHz and delay to 6000 and it worked perfectly! Thank you for helping me with deleting BIOS password for HP EliteBook 8560p. God bless you 👌
Removed no problem admin password from my HP Elite Book 8560p, but most settings are greyed out: admin tools, update sys bios, disk sanitizer, sys configuration, boot options, ...etc
Why you didn't use easy way to remove bios password using 'hpbr utility' 🤔
software doesn’t support the newer models, i just tried
Thank you so much ok for my zbook 15 g2 👍
Best regards.
Don't they have a coin battery in these you can remove overnight that will clear the bios?
This video is amazing, i will save it to the next time i have thhis problem. do u know how to do the same thing but in a hp stream laptop?
There are many threads for 'hp stream' on the badcaps site.
How good or bad idea is to do this with the clips that go over a chip, to remove the need of soldering altogether? Thinking about the traces and the components at the other side of the traces more than the chip itself.
It is perfectly fine to use a clip, but note they don’t always work and some chips just won’t clip due to the low profile.
Hey
What if there is a password but you can still boot to windows ?
Hi, I did the unlock with a HP ZBook 15 G2 and it worked but the options are grayed out and I can't make any changes.
Now set a new bios password and remove it like normal and they should become un-grey.
Also try reset bios to factory defaults option.
@@CoolshrimpModz The last one worked for me, thanks man :)
Great video. I've managed to desolder and u/l the bios using ch341, but cannot find that text string. Can it be anything else? Is a blank manufacturer firmware my best option?
Use the HP tool to remove the password.
@@CoolshrimpModz OK thanks, is that a download from HP? Do you have a link?
Cant you remove the password without opening your laptop
No
is that search specifically for user named admin or would that give you the admin user evern if they renamed everything? Debating on working with a company on a lot of their laptops. Thank you. (the have zbook firefly g7's)
You can clear password of any user or admin account.
Hey, I bought a chip without password on ebay for a ryzen elitebook, do you think replacing the chip will get rid of the password?
Not sure about that model but it should some require 2 chips to be replaced.
hi, I have a zbook 2x detachable workstation and one of the kids accidentally set a uefi password, we can't even boot to windows and hp won't help ... would it be better to just get a new bios chip, and do you know where I could get one? I take care of all our kids computers and phones, but I'm not great at soldering. Ebay is mostly selling from eastern europe and I need to get this thing up and running by the weekend, lol, bc she's starting a digital art class.
Hey yes easiest way is order replacement chip on eBay but it can take 2days upto a months depending where it’s from. Once you get it have a local shop solder it for you. Any cellphone repair shop should be capable. Don’t bother with a big box store most don’t do component level stuff.
Is the hot air blower really necessary to remove the chip? They're quite expensive and I'm looking for an alternative solution..
You can get a clip on programmer and program on the board but sometimes this only works with more expensive programmers. You can also simply use a soldering iron to lift the chip.
@@CoolshrimpModz thanks for your reply! I still don't understand how the bios info is stored on the chip without a cmos battery being present. I removed the battery for a month and the bios info is still on there..
@@dinigi the chip has non-volatile memory allowing it to retain stored information even after power is removed. Like a flash memory card.
Hi, do you think this will work on a Probook 450 g5? And could it work with a soic8 clip?
Yes should work on all of them. And the cheapest option if you only have to do one is buy a replacement cleared bios chip on eBay and just get someone to solder it in. You don’t need the expensive programmer to do one as the chip is only $8-25
I broke the chip on hp probook 4530s do you know how to fix it or where can I buy new chip?
Just to look at label on front of chip and buy new one one aliexpress or in local soldering store. Label should be like W25Q128...
It work with 255 g7?
I can't find any other way to call it biosuser00 with that term, zbook firefly 14 g8,
It has HP Wolf Security block.

@@CoolshrimpModzthe process it's the same for the Huawei Matebook D15 cause I can't find anywhere on the damn internet how to remove the BIOS POST Password, please answer. Thanks!!
Can't you just remove the CMOS battery for 6 - 10 mins? I read that that's al you have to do on the HP web site.
That worked on laptops like pre 2005 or so. Newer systems now have non volatile memory that doesn’t need a battery to retain settings. So only thing removing a battery does is lose time. Dell and HP are easily bypassed by editing the bios image externally, Lenovo you use a custom injected EFI to the bios to bypass tpm where the password is stored.
Can I take out the bios finally and not putting it back on the laptop?
Will the laptop still work fine
If you remove the chip the laptop will not turn on. A Chip must be installed to power on. And must be correctly programmed. Make multiple first backups keep them safe as they can be reprogramed to repair it even if you need to replace the chip.
Not work on my laptop Hp zbook 17" g2.
Could you help me with my elitebook 8470p
Hey I love the video, I have the HP Spectre x360 it's a little different because it doesn't let me load bios at all it just prompts me to the Administrator Password or power password screen right away . Then recommends the HP sparekey recovery option. Ive done some troubleshooting but do you think I could reprogram the chip on this board aswell? Any advice helps thank you.
At the password screen, hit enter 3 times and you should receive a 'halt code' - try using the code on this site to generate master key.
bios-pw.org
Chip removal is an option but since most hp can be done without bios chip reprogramming try that first.
@@CoolshrimpModz I've tried removing the rtc battery I'm afraid to use the paperclip method where some say it shorts the two pins from the rtc battery and resets the bios . I bought another battery and tried with no luck . I even called HP and tried there steps but we can't get into the bios . It doesn't prompt a halt code either.
@@paulzeev can you send a screenshot of the password screen you see. And error screen after 5+ failed attempts.
@@paulzeev I just contacted one of my sources they say if you enrolled the spare key feature you will have to follow similar method as video and clean/reprogram bios chip.
Hi, I got a zbook 15 g2 from second hand but unfortunately the seller forgot to mention that the bios was locked. My friend has a ch341a programmer with a clip, can I just use that to flash the bios instead of desoldering it?
You can try, look for the bios chip read the model and make sure your programmer can support that chip. Then you can try reading it in system. But many times it dosent work and you may have to solder to reprogram it.
@@CoolshrimpModz My main concern is damaging the bios chip if something goes wrong. I'll try in a few days, after I get the programmer
@@zadkielalfano you can order replacement or even a new clean bios chip on eBay, just don’t damage the motherboard when soldering if inexperienced ask a local shop to assist.

No the password is not stored in plain text it is encrypted, we are simply erasing/replacing it.
@@CoolshrimpModz do you think the password could be decrypted? I imagine they used some salt. The docs for up say the password is aes encrypted, and that’s a symmetrical algorithm. I have 400 devices that are locked at bios so it’s worth decrypting the password once rather than for every single one
@@antokh there may be some tool but I haven’t used one, but I’m sure someone’s made something. if anything a rainbow tables tool basically they lock bios with a list of words then read the encrypted version then you compare your encrypted password with the list and you’ll know the starting password.
