DELL INSPIRON N5010

I am owner of my Dell INSPIRON N5010 , but i m not from USA , my computer hanged so my friend just restored its BIOS setting( i am not sure if these are called BIOS, but it happened as: he restarted Laptop, pressed F12 and there he restored settings 
then when it restarted there appeared a black screen in middle of which there is a blue box saying "Insert system password" 

Now i tried looking over internet all over the place 
I found out a few reasonable solutions 

1- remove a battery with motherboard , but for that you need an expert for which my laptop might have to opened which i prefer not to get opened 

2- second provide your service tag(S/N) on dellpasswords.com but that asks for $35 which i think is just too much! 

Now I want if the second one can be done for free or anyother viable solution 
thank you
