So now I need to find a replacement but can't get to know which exact model and where to find it. Will attach one pic of the lil'...

Working on this board that according to client died after he dropped the computer. Already swapped U7090 but no dice. Board has no signs of water damage. Edit 1: Managed to get pp3v42 stabilized to 0.9v after replacing a cap right before u7100. Then replaced u7100 and the voltage raised to...
