PDF schematic for the HP EliteBook 2540P business notebook, built on Compal board LA-5251P, revision 0.9, in a RAR archive of about 1.3 MB. Compal is the ODM, and LA-xxxxP is its standard board numbering. The drawings let you trace the charger, system power rails, EC and power-on circuits when a laptop is dead or will not charge. Revision 0.9 is an early issue, so compare the revision silkscreened on the PCB before relying on component details.
