Explanation

Before performing any internal hardware work on a laptop, both external and internal power sources must be completely disconnected to protect the technician from electrical shock and to prevent damage to sensitive components through electrostatic discharge (ESD) or accidental short circuits. Unplugging the AC adapter removes wall power, and removing the battery eliminates the internal power source. Together, these two steps ensure the laptop is fully de-energized. Removing the keyboard, separating the screen, or removing all bottom screws are model-specific disassembly steps that are not universally required for memory replacement and would typically come later - they are not safety prerequisites.
