Hi, I have a Dell Latitude D620 with service tag #3TSFN2J-595B, and I can´t access the bios, i´ve tried the shorting method but it haven´t worked, there is no eeprom to flash... I also tried the master passwords you give in some threads, with no luck... I disconneceted the CMOS battery, no luck...
I also tried the boot cds you link in some posts, but i can´t not boot from the cd even if i take out hdd...I´m becoming crazy! could you help me?

Thanks in advance from Spain,

Mauri Gómez
 
Short answer: You need the original password.
That unit has been refurbished by a Dell-authorized shop (as all with the 595B are) so the restore discs cannot be used.
All of the suggestions your tried, are known not to work in that model... The D600 and D620 are the most difficult of all Dells to fix. You will likely need to replace the motherboard with one known to work. Most of the boards on eBay have the same problems you have.
 
Ok, thanks for the help, but I think is not necessary to replace the motherboard, I´ve heard that is possible to generate the master password having the service tag, anyone here knows something? I´ve tried several password generators but they don´t work with serial tag ending in 595B, please help!

Thanks in advance
 
If you are successful, let us know.
We see a great number of these machines, and have skilled technicians trained in password fixes, and password generators. I do not know of one system that has been fixed, but some say Rustam on this forum (now retired) has been successful. Due to the range of possibilities which run from 6 digits to 19 digits, upper and lower case, spaces, dashes, and tricks... the mathematics of it is against you.

From our experience, I would rate the D600 and D620 as two of the most difficult laptops for which to fix passwords.
At our shop, we pay $169.00 for a D600 or D620 motherboard, Dell Sealed, or
$119 for a Dell refurbished motherboard with a one month warranty.
We find too many others sell the defective board.
 
Hi raybay, thank you for the quick reponse... I think its possible because I´ve seen several places on the internet that offers the master password if you pay them. For example spam link removed

So they must have a kind of keygen, don´t you think? I´ll continue investigating, if someone of this forum can help us it would be very much appreciated!

Thanks in advance
 
Yep, he can fix a few... for $95, when the motherboard is $114. He does provide free shipping back... and his feedback is good, but he is limited to five Dell models. Or perhaps he just replaces the board, which he could do in volume... as the technician price in volume is $49. I suspect he has a Dell-Authorized contract with Dell.

He can do the D620, but not the D600. The D620, D630, and D420 are essentially the same motherboard. The XPS would depend on which models.
But fixing it for $95 is a price worth paying.
If you try it, let us know how it went.
 
No, he doesn´t replace the board, he gives the master password if you give him the service tag, read the entire description... So meaby you could save some money and work ;-)

But we must find a way of bypassing this password without paying, don´t you think? If you take a look to the posts of predator25 in this forum you´ll see he also can get the passwords! I´ve send him a private mail but his mailbox is full!
 
from what I remember predator25 gives hdd passwords for dell laptop out for free but he charges you some dollars for the master password which usually removes every password else.
Maurafarah, can tell again exactly what password you mean. there are often confusions with bios pw, system pw, primary pw and hdd pw. so maybe we can help you without a master pw!?

I think he is able to give both passwords. The password im talking about is the password of the green screen of doom, not the hdd password...
 
Did you tryb calling Dell? I used to work for Dell and you just need to the service tag and they can help you. Call customer care.

Click to expand...

yes, but propably not for the same price :D
well if its the gray screen then you can hope for a master pw only or try to get an arrangement with dell... you need to proof the legal ownership then!
 
Im notice mistake about 595B.

Brief explanation:
dell have many models, old models use various password systems but now it obsolete. Then its used 5-digit service tag ended with D35B to generate master password. Then they produce 7-digit service tag ended with D35B, but after one person (Christophe Grenier) public the latitude.exe (Latitude_MasterPW.exe), Dell changed ending to 595B. Now no any public tools were able to generate master password for service tags ended with modern ending 595B, only few person may generate master passwords, but it independent from model.
Mostly all Dells model have now -595B service tags, but since D620, D420, D820 it is impossible to use well known paperclip method, so D620 is more difficult than D600. But mostly difficult is Toshiba challenge method :)
other brands like sony, samsung, asus, fujitsu-siemens, hp have less difficult passwords.
Also please stop bother me about helping to unlock, I will help only for very old systems, so if you bought for cheap brand new locked computers - it is your problem.
Do not promise me any money or things, its uselessly, as well as any crying and insulting my headache.
 
Hello,.. I have a Dell Laptop I'm having difficulties with. I keep getting the gray screen. It was given to me by my brother when his daughter ( my niece) passed away. If anyone can help me out with the bios password I would be immensely grateful.

It's a Dell XPS M1210
service tag 4VB7PC1


thank you for your time.
