Hi Rajesh,
my friend I suggest , if you really need the informations trapped in that laptop, to find a good , trusted... ehm... "hacker"

I KNOW trusted hacker maybe is not self-explaining ... I mean you need someone that can read the whole Dell thing content without any Admin pwd or something...

I think you may ask people from some e.g. local unix/linux club maybe... or similar folks ( you may recognize them cause often they wear t-shirts with labels like "fu** the system" etc... ) :lol:

I'm sure you'll find a couple of guys ready to hack-down any data there... for free! :lol:

BUT , do not contact these guys by email... better buy a ticket for the next linux-day and wear similar t-shirts there... just to seem like one of them...;)

Kind regards,
Max

If this is a more modern laptop, it may have a security chip, and removing the battery will not work. Depending on the chip, you can short together certain pins, and that will reset the BIOS.

What is the make and model of the laptop?

hi qiaozhi sorry iwas out door for hunting. this is image back side of laptop

whos the ic wiil be reset

There is a program here that will calculate the master BIOS password for Dell Latitudes from the Service Tag number -> http://www.users.globalnet.co.uk/~sk...s/latitude.exe

You need to open a DOS window (obviously on a different machine) and enter "latitude 12345", where you replace 12345 with your service tag number.

I also read somewhere that you can use a backdoor BIOS password. Trying entering "Dell". This is claimed to work for some Dell machines.

About the "latitude.exe", you can save it wherever you want, but you need to run it from the command line.
It wants a 5 letter service tag number - yours looks longer than this.

A good Hardware Hacker can solve the Password Problem like this :
