Can anyone identify these two ICs from a laptop motherboard?

    \$\begingroup\$ Considering everything points to these being power supply ICs: if they have failed, they've with a high likelihood fried something else, too. That's not absolutely certain, but if you're assuming that "just" replacing these ICs will fix your notebook: expect to research much deeper. \$\endgroup\$ – Marcus Müller Dec 12 '17 at 10:30

It seems to be a step down controler. You can find here the datasheet : datasheet.

For replacements, I invite you go on the TI power supply test bench and simulate the need of your circuit. The website will advise you the proper chip. Link here
