The soder is cracked, or the chip smells like melted pastic...

When BGA chips go..

What is the model of your laptop? and the chip?

Do you hear any noise when you turn on the computer?

I really think it is dead.
And the only thing you can do now is to buy a new laptop, or get the BGA chip replaced:

I was not able to find any documentation related to your laptop.
