"Insert smart Card" message on HP Compaq nc6220

Thank you all you folks for helping me with my previous computer issues. I have an HP Compaq NC6220, which when powered up displays a message right at the BIOS ( even before I can enter BIOS ) " Insert Smart Card ".

I can't get past this message at all. I tried all kinds of combinations to get to BIOS, but nothing seems to be working. :- ( I am not able to go beyond this message.

Could i bypass it by removing the CMOS? Or what else can I do? Please help.

Different model, but similar problem:
