In order to remove internal components of the Satellite Pro C40-G some tools from the list below may be
required located in Chapter 4 Replacement Procedures of the Dynabook Maintenance Manual
For your safety and the safety of the people around you, it is important that you use Electrostatic Discharge
(ESD) equipment. Correctly utilizing of the equipment increases the percentage of successful repairs and
saves on the cost of damaged or destroyed parts. The following equipment is required for disassembly and
assembly.
■ One Philips screwdriver with type 0 bit (for S-THIN HEAD screws)
■ One Philips screwdriver with type 1 bit (for screws other than above)
■ One flat-blade screwdriver (for removing the CPU)
■ Tweezers (for lifting screws)
■ ESD mats (lay on work table or floor)
■ An ESD wrist strap and heel grounder
■ Anti-static carpet or flooring
■ Air-ionizers in highly static sensitive areas
■ Antenna coaxial cable disconnector
■ Special syringe (for applying grease)
