Technical Specifications
Technical Summary
This Compal Electronics document covers the LS-4732P T/P on/off BOARD, a touchpad on/off sub-board. The main schematic document is identified as LS-4732P, revision 0.1, dated August 22, 2008. The board interfaces with the main motherboard via a 4-pin FFC connector (Z1) and includes a tactile switch (SW1, TJG-533-V-T/R_6P) for touchpad enable/disable. A bi-color LED (D1, HT-297UY5/BP5_YELLOW-WHITE) provides status indication, with white for enabled and amber for disabled. The circuit utilizes an N-channel MOSFET (Q1, 2N7002_SOT23-3) for control. Resistor values were revised in a later change list, with R1 changed from 390 ohm to 1.2K ohm and R2 changed from 200 ohm to 2K ohm.
