Acer Aspire 3935 Notebook Computer Disassembly Instructions

System Disassembly This document provides step-by-step instructions on how to disassemble the computer for maintenance and troubleshooting purposes. Disassembly Tools In performing the disassembly process, you will need the following tools:  Wrist-grounding strap and conductive mat for preventing electrostatic discharge  Philips screwdriver  Flat screwdriver  Plastic flat-blade screwdriver  Plastic tweezers Stages of the Disassembly Process The disassembly process is divided into three stages: 1. External modules disassembly 2. Main unit disassembly a. Upper case disassembly b. Lower case disassembly c. LDC module disassembly IMPORTANT: The disassembly procedure described in this document is a gradual process, as illustrated in the flowcharts preceding each disassembly stage section. This means that users need to observe the instructions in a step-by step manner. To illustrate, if you want to remove the mainboard, you must first remove the keyboard, then disassemble the inside assembly frame in that order. Failure to observe the gradual process may result in component damage. NOTE: To reinstall the system components and assemble the unit, perform the disassembly procedures  in reverse. Equivalent Torque Values Torque values indicated in this document are expressed in kgf-cm (kilogram force-centimetre). For equivalent values in in-lb (inch-pound force) and N mm (newton millimeter), refer to the table below. kgf-cm 1.6 2.0 2.5 3.0 in-lb 1.39 1.74 2.17 2.60 N mm 156.93 196.17 245.21 294.25 1

System Screw List Listed below are the screw types used in this system. NOTE: The screws for the different components vary in size. During the disassembly process, group the screws with their corresponding components to avoid mismatches when putting back the components. Code A B C D E F G Type M2 x L4 M2.5 x L5 M2 x L3 M2 x L3 M2 x L4 M2.5 spring M2 x L2 Color Black Black Black Black Silver Black Silver Pre-disassembly Procedure Before proceeding with the disassembly procedure, perform the steps listed below: 1.
