    ACY25 14.1” & 15” INVERTER SPECIFICATION General Description There are two control signals that come from system to control lamp brightness. One signal is named DAC_BRIG, which limits current to meet LCD lamp current specification. Another one is named PWM, which adjusts lamp brightness. This inverter brightness is adjusted by PWM burst mode.

  • Page 79: Disassembly

    Chapter 5: Disassembly General This chapter provides detailed directions for disassembling the computer. You will require a medium size screwdriver, small screwdriver and a 6mm nut driver (for the helix screw nuts on the rear ports). Before starting to disassemble the computer, refer to the diagram below. This indicates which modules need to be removed to access the module needing replacement.

  • Page 80: Remove Keyboard / Button Board

    The example below shows which modules need to be removed before the audio board can be removed and repaired or replaced. The audio board is overlapped by the top cover, which must be removed before the audio board can be reached. The top cover is in turn overlapped by several other units (shaded gray) and these must be removed before the top cover can be reached.
  • Page 81 Safety Precautions Before you begin disassembly, read the following safety precautions and observe them carefully as you work. DANGER: Always use the lithium ion battery pack or backup battery that is authorized by the manufacturer or compatible with the unit. Since other battery packs have different specifications, they may be incompatible with the unit, and may burst or explode.
  • Page 82 Before You Begin Look over the procedures in this section before you begin disassembling the computer. Familiarize yourself with the disassembly and reassembly steps. Begin each procedure by removing the AC adaptor and the battery pack. 1. Do not disassemble the computer unless it is operating abnormally. 2.
