4 Replacement Procedures 4.1 General Safety Precautions Before you begin to disassembly read the following safety precautions carefully. Be sure to follow them while you are working. DANGER: 1. Always use the genuine batteries or replacement batteries authorized by Toshiba. Batteries other than those differ in specifications and are incompatible with the computer. They may burst or explode. To avoid leakage of alkaline solutions, never heat or disassemble the battery packs. Never throw the battery packs into a fire. If this is violated, they will explode. 2. The components such as the power supply and FL inverter carry high voltages. When you partially disassemble the computer and turn on the components, use extreme care not to touch the connectors and components to avoid the risk of electrical shock. Do not disassemble individual components during first-level maintenance. WARNING: 1. To avoid the risk of electrical shock, turn the computer off and remove the AC adapter from the electrical outlet. 2. Because the battery in the computer is left charged, the risk of electrical shock remains even after the AC adapter is removed from the electrical outlet. To avoid the risk of electrical shock, be sure to remove any metal jewelry or accessories such as necklaces, bracelets, and rings before starting work. Never work with damp or wet hands. 3. To avoid personal injury, use care to avoid the sharp edges or corners of the components. 4-2 Satellite L300D/L305D/ Satellite Pro L300D/ EQUIUM L300D/ SATEGO L300D Maintenance Manual
