Question about Computers & Internet
SERVICE TAG NUMBER HR9C831 , EXPRESS SERVICE CODE 38653573357
My son was given this laptop by a woman that lost the power supply and forgot the BIOS pass word.
Can you give us either a universal unlock code or tell us how to by pass the BIOS password. We tried removing the BIOS battery overnight but that didn't help. Evidentaly it has a high end chipset that does NOT use the BIOS battery to retain the password.
Dell uses NVRAM which retains the password forever regardless of removing the battery as you now know. The service tag number is used with a keygen to generate a master password. As a Dell tech I can tell you that what I have done is to go to Dell's support site, add this laptop to your own products where you can enter the service tag number then ask Dell support for the master password which they will provide with their keygen. This is the only way you can access the BIOS setup where you can choose a new password or disable the password. If the service tag number you enter shows another registered owner you can just have them do an online transfer to yourself. Then you will have full access to customer service. Steve Medley

Usually there is a jumper to clear the cmos which will reset the bios password should be near the battery.
There is 3 prongs the jumper is on 2 you need to move it to cover the one that the jumper is not on.
Either that if there is only the jumper just remove it and then reseat it.

Tips for a great answer:
Each Dell Inspiron has a master password that clears the BIOS password. Call Dell Technical Support at (800)624-9896 to get this number.
Dell Technical Support will request the Service Tag and Express Service Code from the bottom of the Inspiron.
If the current user is not the original Inspiron owner, Dell will transfer the used Inspiron's registration from the original owner with only the Service Tag and Express Service Code from the tag on the laptop.
To transfer a used Dell Inspiron's registration, fill out the Transfer of Ownership form on Dell's web site. See... http://www.tech-faq.com/reset-dell-bios-password.html
