What safety precautions should I follow when replacing the battery in my HP EliteBook?

To avoid personal injury and damage to your computer when replacing a battery, do not puncture, twist, or crack it; handle with care avoiding metal tools near connectors due to risk of shorting. After disassembly preparation steps (off power, disconnect devices), carefully lift tape off battery cable connector, disconnect this from system board, remove speaker cable along battery's bottom edge, and unscrew retaining screws holding the battery before safely removing it from your device. Insert replacement using same care reversely detailed here (Pages 32-41).
