PDF schematic for the K42JV motherboard, revision 2.0. The 2.44 MB document should include power regulation, charging, CPU and chipset sections and the discrete graphics circuitry associated with this model.

Confirm that the main board is marked K42JV rev 2.0, as earlier or later revisions may use different component values.
