Hi Dogbert. Have a Latitude E6400 with serial ending -2A7B which I have put into the password generator and got several passwords. Have tried entering all of them using external usb keyboard but none worked. Any ideas what I may be doing wrong. Cheers.
that might be an issue with the keyboard layout - you have to enter the password assuming that the keyboard layout is US-en
Great work as always Dogbert. I have used this on different machines over the past 5 years and still works. Just used it on a Dell Latitude E6400 and works great. one needs to follow the instructions carefully and you would be amazed. Excellent work
My daughter got an old Toshiba Satellite 1105 and it had a password to access the BIOS. I fiddled with it for days before I ran across this site and could not make any headway. When I saw the hash decryption note, and I knew that I had seen the code flash by when I entered the wrong password three times, I knew that I was onto something if I could just get that code. It flashed by so fast when the third bad password was entered that I thought that I might not be able to ever get it, but I pushed the pause key at almost the same time as the third 'enter' password and it stuck. Using that code, I was able to get several possible backdoor passwords from the site. The first one worked, allowed me into the BIOS and I was then able to clear the passwords for the 'supervisor' which was what was set. So now all of the passwords are cleared, and I have control over the computer to allow me to go through and set it up for my daughter. I am so very pleased that I did not have to disassemble the laptop since that is a real chore and one that I don't even like to think about. I owe you Dogbert!!! I don't know who it was that wrote the code for the hash decoding, but whoever it was is a hugely appreciated soul!!!
So release some technical information on how your reversed the key-generation algorithm so that others can continue your work. Fujitsu is already using a 6x4 decimal Key
acer aspire 7741 what should I do its not mentioned ?? code is (redacted)
@Salm Mous,which way worked for you?I have an E4300 and it never says system disabled and gives me a number,it just shuts down after 3 incorrect tries and you can keep trying.Also have an E5510 with same problem,got them off eBay and both locked.Dell support is very rude and seemed like they didn't know what was going on,acted like I stole the computers even after I offered to send a PayPal and eBay receipt.I really don't want to give them even a penny!
How to reset bios password in Toshiba satellite C855-2j5 ... i tried to get out CMOS battery ... also make short connection near the battery at jrst2501 ... but still dont work ....any solution please.. Thank You
Remove RAM cover under laptop and search for B500 pads around ram memory area. Then the procedure is to short B500 pads and power on computer, once it POSTs remove short and system password will be cleared.
IMPORTANT: Be very careful not to short anything else, you can cause damage to motherboard.
There is no B500 for this motherboard ....all pins are named with jp or jrst similar .... near the CMOS battery is jrst2501 i tired to give short contact but there is no changes
I did one of those a few weeks ago. I had to solder a thin wire to the pin i think the jp one. I connected a push button with the other side to ground. I held the button while booting up. Then rebooted, It worked like a charm. Trying to short the pin with a paper clip didn't work, couldn't get a good enough contact.
Have you tried to remove the hard drive? maybe this isn't a system password, but an hdd password.
Could you post the complete model number, what follows C855 (ex.: C855-xxxxxx)? look under computer.
Dogbert YOU ROCK. my elderly father-in-law somehow locked himself out of his laptop. YOU saved the day!! what charity is your favorite so i can donate to it in your name?

Hi Dogbert,
im using Sony viao Eseries. , i forgot my bios password and i tried the methods that u have mentioned above.. but at the time of "system disabled" popup , its not showing any Checksum code to continue ... what i need to do ..please help me out
Dogbert do you have a way to do these newer machines. For instance a Dell Latitude E6410, E6420, E6430 and so on. I have a bunch of these units in my shop and would like to knock them all out. I am hoping you have a page or an app.
I have decided against releasing it: please use the dell support
So, the only way to get help on a machine such as the Dell Inspirion N5040 is to contact Dell Support? I called them, and they want $130 to unlock it. That is an outrageous cost, in my opinion.
just wanted to say thank you for making it possible to use my old locked up HP Mini 1101 again!
Worked great on Packard Bell easynote tj74 - phoenix bios ! Thank you so much for the info :)
absolutly perfect i can help a lot of people with this with out free support they are helpless because they dont have any money thank you from holland
Hi I have used your PW generator on Dells with 595B allways with sucess , but now I have an Dell Lat 2120 with 2A7B and when generated key entered I only come to another screen where I have to enter the old password , have tried with an USB keyboard as well , no sucess, Any tips ?
Solved , You have to fill in the generated password once more .
Little bit weird since it ask for old password.
gracias desde Colombia me ayudaste te agradezco por tu labor, si vienes aquí una vez cuenta con un amigo que te sera de guía y gastara las cervezas.
What psw generator have you used for LifeBook A530? Thanks
Man thanks a bunch! How can I donate to you? I have looked left and right for something that worked and you offered it for free. So i would like to give back for your hard work.
if you donate a few bucks to the animal charity, you'd make me happy :)
Hi there, I have been working on my friends Alienware 17 with Bios InsydeH20 version 03.73.02A03 and i need to set the nvidia card to discrete so its not using the integrated intel chip, but the setup is locked, graying out almost every option. I tried the bios-pw system disabled code but it isnt returning anything. system disabled code is F2FF5B5B07D3E7BD and the service tag is (redacted). Thank you so much in advance for taking the time to help me out!!
I Just wanted to say THANK YOU SO SO MUCH!!! This is my neices laptop and I don't know how the BIOS got locked. But Again Thank You so much. It worked on an HP G56 Prod XG598UA#ABA
