    Smile Dell d630 bios reset.

    A mate of mine has got his hands on a Dell latitude D630 only snag is it has a bios password set i said i would have a look, i thought just disconnect cmos battery few mins sorted no chance lol, a little more reading i could short the atmel chip, paperclip method no chance not on the D630 but i have come across this for 30 notes so i know it is doable.

    DELL MASTER PASSWORD 595B 2A7B 700m BIOS UNLOCK SERVICE on eBay (end time 23-Mar-10 16:08:32 GMT)

    Any one know a way round this or had a similar situation, any input appreciated cheers.

    Re: Dell d630 bios reset.

    these any use before you shell out good old cash

    list of some std passwords

    BIOS - Master, Setup and Boot Passwords

    This is a dos program to calculate the master password based on the service tag number

    Go into a DOS session (Start > Run > cmd)

    Go to the directory with the LATITUDE.EXE program in it (size is only 5,467).

    Type in latitude 12345 and hit enter.You have to substitute 12345 with your 5-character service tag number. The program then gives you the password.

    http://www.users.globalnet.co.uk/~sk...s/latitude.exe

    or theres

    CmosPwd - CGSecurity

    that should keep you going for starters

    Re: Dell d630 bios reset.

    How do Jackel, i did an acer aspire 2930 at the weekend and it worked by pulling the cmos battery.
    http://www.digitalworldz.co.uk/23123...-unlocked.html

    I was told by a technician that the battery must be at minimum disconnected for 1 hour for it to work.

    With the acer it was soldered onto the motherboard and he told me to just disconnect the positive terminal which i did by accident as i was full of cider.

    A tried all the passwords i could find and none worked.
    It was the missus old lappy and a had nothing to loose if a bricked it.
    When a first powered it up i had nothing but a black screen so i took all the cards and hdd out and re seated them.
    I put the ram in a different slot and tried again and it powered up and the lock was gone.

    good luck..

    The Dell D630 you need to use the paperclip method and it works. Have done a number of these.

    its the 2E8C chip located on the motherboard. When i get home I will send you the Pinout.
    I think it is pins 2 and 8 you short and that resets the BIOS password.

    @devil don't supose you have any info on the D620 m8, I've had it in my spares box for over a year n seems such a shame as it's a nice looking laptop.

    I'm pretty sure the paperclip dosn't work from my last google, and haven't seen a Public PW generator for it but I live in hope, any info would be appreciated.

    Cheers

    No mate it wont, it will just damage the PCB.

    Search google for "Dell BIOS password generator"...loads about.
    Once you enter the password, dont press enter, press CTRL+ENTER.

    Also, @theJackal, what processor does it have? If its the dual core...it wont work, if its centrino and less, then it will work. (sorry, should have said that earlier.)
