Hello Senthil,

I think I have the same problem that Amirala. I need to unlock my "admin password" or "setup password". I can access my BIOS but I cannot do nothing there, like activate the TPM security.

By the way, my laptop is a Latitude E6430. Is there a way of Dell restore that password?

Thanks.

Call Dell, verify ownership. There is a charge for the call and service if you're out of warranty.

Dell System prompts for a Hard Drive (HDD) or BIOS password

how can i verify ownership?

You need to place a voice phone call to Dell support.  Be prepared with your ownership details (name, address, phone number) - they will verify that before assistance is offered.

I can not speak English.

Is there an address I can resolve via mail??

thanks

No.  It needs to be done by voice call.  

I called the service in my country.

They were not helpful.

Password my own responsibility :/

Motherboard replacement recommended :D

second hand.

But as I said

Bill and box
