Quanta BL1 laptop board schematic, revision 1A, in a 919 KB PDF file. BL1 is a Quanta project code, and Quanta manufactures motherboards for multiple notebook brands, so the retail model is not given. Use this diagram to follow rails from the DC input through the charger and system regulators, check the enable and power-good signals, find components on a shorted net and confirm part values. Verify that the silkscreen on the PCB reads BL1 rev 1A before trusting the pages, since other revisions can differ.
