Hardware Switch no backlight and cracked chip

[LegendOfLink32]

Customer brought in switch to get the usb port replaced. After replacing it I noticed that no backlight was coming on. Inspected the board and found this chip cracked. The letters and numbers on top look like 4ALJ 928. Any help is appreciated.

Found the chip, thanks to Severence over at tronicsfix. Part is a Max8969. But now I’m running into a different issue. The switch powers on but switches from .497 amps to .096 amps when powered on. M92 chip replaced. Bq chip replaced and p13 chip replaced. Any ideas?

Check for resistance on the 1,8V 1,3V lines. They can be found around max77620 ic
