This is Dell N4110 laptop.
The chip (circled) is gone, I can tell. But I cannot figure out the exact number. All that is written on it is "290".

Based on what it seems to connect with I would bet it is a buffer or schottky input opamp for shaping up a timing train signal.

I do not think it is a custom part. Just the number is too long to print on it
