Thank you and best regards.
Unless you can register the system with Dell (which means contacting the registered owner), you will need to replace the mainboard.
This is the part you will need:
you dont have to buy another motherboard to remove a bios password all you have to do is remove the cmos battery and it will reset it =P that is located somewhere on the motherboard sometimes they have jumpers they call them you can flip its kina like a switch some have to have 2 wires soldered on to a chip and touch them when its coming on to short it out which is how you remove the password and some just unplug from the motherboard im not sure which yours is but thats how you do it no need for another motherboard =]
after removing the battery is asking for bios password on boot, i can`t even boot from usb now. i try to find a schematics for the motherboard. thanks for tips.
There are no jumpers - nor is the password stored in a battery-backed chip.
i know the chip can be shortcut for reseting the password , but is not a easy way to provide me the master pass for my service tag ? is too bad to trash a good motherboard.
The master password is system specific. To obtain it you must call Dell, prove you own the system (which you cannot) and pay a $60 support call fee.
