@yahnke123 ok so it looks like your board is a 5B20Y89742 Wistron OEM LC40CM. That make this IC reference designator PU5451 which is a NB694GD-Z-GP Monolithic Power System Switching Voltage Regulators. Something I learned while trying to find a supplier, was that usually parts with a horizontal line above the marking code, are monolithic power. Anyhow, I have found a few places with a quick online search, but do not know the suppliers and thus could not vouch for their reliability etc.
This maybe a situation where you need to consider either finding a donor board, or taking a leap of faith and order from a Vendor that appeals to you. Sorry, that is the best I can do. Hopefully @jayeff or somebody else can find out more about this.

Hi @oldturkey03,
I agree that the horizontal line above the marking code indicates that it is a monolithic power IC.
Finding the AWV manufacturer's website is difficult to say the least as there's nothing online regarding that "prefix" as a manufacturer's code for their products.
As for the rest, you've done better than me at finding a free? download for the schematics but I have no doubts that you are correct as to the part number.
Cheers

Thank you guys, really do appreciate the help, so the PN NB694GD-Z-GP Monolithic Power is what I should order then just do a chip off.
