Datasheet in PDF for the Texas Instruments BQ24770 and BQ24773 battery charge controllers, 794 KB, catalogued here under schematics. These chips are notebook charger controllers configured over an SMBus or I2C interface. A technician uses the document for pinouts, the typical application circuit, the role of sense resistors and the expected voltages on key pins when a laptop does not charge or will not run on adapter power. Compare the marking code on the chip with the datasheet package information before measuring.
