Revision 1.0 schematic for the Pegatron HE4EA board. The name gives only the project code and revision, with no laptop model, chipset or graphics details. Pegatron designs and builds motherboards for a range of brands, so identify the board by the code printed on the PCB. The PDF can be used to trace power rails, follow the power-on sequence and check connector pinouts during repair. Confirm that the PCB revision is 1.0 before relying on component values.
